Tegheim - Home made 4 rotor Wolvo 142

[Tegheim]

Hi!
Mazdabater on Ausrotary pushed me into this forum.

I will give you a big intro later this week, but wanted to give you an teaser :)

Check this album out for all pics. Will put some of them up here later as I said.
Tegheim's Wolvo 142 with 4rotor (http://s815.photobucket.com/albums/zz71/Tegheim/My%20Wolvo%20142/)

Here's some teaser.

Welcome to the site! How could rcc not have the craziest build I have ever seen on it!

[RICE RACING]

Welcome to the site! How could rcc not have the craziest build I have ever seen on it!

If only BDC were allowed to join, we could have the craziest along with the gayest, all in one site :smilielol5:

[Tegheim]

Thank you! Who/what is BDC? :-)

[TitaniumTT]

Welcome! Mazdabater was wise in his ways to drag you over here. Build looks badass and I'm very curious about the 4-rotor. Fabrication is always a good thing, the more the better!

[TitaniumTT]

Thank you! Who/what is BDC? :-)

Who, and he's the rotary worlds punchline. There's a thread in the lounge that's worth a read, lounge is able to be viewed once you have 20+ posts..... buuuuuuut, if you can't wait, I can hook ya up ;)

[My5ABaby]

Holy fabrication. That's a very impressive build. Can't wait to see it finished. I demand a dyno ASAP... :icon_tup:

[FC Zach]

Welcome :seeya: and . .. . . HOLY CRAP :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly: :willy_nilly:

[Force13b]

I love this build i've been fallowing it on the other site for a while.

[TitaniumTT]

You love anything with long shafts in the pictures :rofl:

[vex]

needs more cow bell.

[Force13b]

You love anything with long shafts in the pictures :rofl:

If that were true i wouldn't like you so much now would I ;)

[-xlr8planet-]

Good to have you here!

[TitaniumTT]

If that were true i wouldn't like you so much now would I ;)

I generally only take the pics when it's dipping in stomach acid so there wouldn't be that much shaft left showing ;)



More fab pics!!!

[Tegheim]

You will get some more cowbell soon! Have been away all weekend, and now back at work :)

[vex]

What program are you using for modeling? It almost looks like Inventor if I had to guess.

Almost 99% i MasterCam X4-5, not much in Inventor, though I have that too...

Thank you! Who/what is BDC? :-)

welcome to rcc !
as for BDC research his name !

We start small :)

This is the beginning of my new chassi in the Volvo 142 from 1973.

Damn son, that's some grade A+ fabrication right there.

More Chassi, and the welding-jig to put the car on when I cut the floor out.

[MazdaMike]

Holy shit how long did it take to make all the components for the e-shaft? And how many times did you measure?

[Force13b]

I wish i could come hang out at your shop for a year or so to learn.

[RotorDad]

Beautiful work thus far! Definitely interested in this project.

[Tegheim]

Holy shit how long did it take to make all the components for the e-shaft? And how many times did you measure?

Hmm, I really don't know. Too long :) I had to learn how a CNC-Lathe worked first, so the E-shaft was my training-tutorial :) But there is many small things that took long time in total.


I wish i could come hang out at your shop for a year or so to learn.

Haha, I don't have a shop, its my work-place. The boss lets me use the machines after work and weekends. Free Education he says :)

Hopefully that will stay then :D

[MaczPayne]

Astonishing work. A CMM even!

[need RX7]

This is awesome. :bowdown:

[Tegheim]

cmm?

[Tegheim]

Tomorrow my little friend are going on his first journey by himself... :cry:
We'll hope it works out fine :)

[reddozen]

What kind of lobe orientation did yo use? 90's or 180's?
It kinda looks like 180's from the pictures.

Nice work man!

[Force13b]

Haha, I don't have a shop, its my work-place. The boss lets me use the machines after work and weekends. Free Education he says :)


I'm fine with being a live in janitor :lol:

[reddozen]

It kinda looks like 90's now that I'm looking at it again.

[Tegheim]

Haha, you can be my janitior, I won't fight you :)

Yes, It's 90's.
The ignition follows 1,3,2,4.

[Mazdabater]

Where did you have to send the shaft too? Whats getting done to it now, plating?

[Tegheim]

I'm sending it to a engine-shop, that also machine some details to the Koeingssegg by the way.
And he will get it straight again. I have a warp on 0.2mm i the middle after all machining and heat treatment. And we want it below 0.04mm.
After he will send it back, and I will continue the prod.

[NoDOHC]

This is an amazing build! I definitely like the custom eccentric shaft, do you intend to use 13b intermediate plates or 20b intermediate housings for the end rotors?

Awesome build!

Keep up the good work.

Keep up the good work.

The plan is to use 13B-parts. But we are thinking a bit of doing own intermeditate plates... But thats only a dream this far.

[diabolical1]

... we are thinking a bit of doing own intermeditate plates... But thats only a dream this far.

though i know it's been done before, that would be far out.

[TitaniumTT]

WOW is all I can say. I would LOVE to do a 4 rotor in a '68 Charger.... Hell I would out a 4 rotor in ANYTHING for that matter. All this does is solidify the fact that I need to get some machinery and learn how to use it.

Tegheim we need updates!

[N.RotaryTech]

Tegheim,

[Tegheim]

Thank you all, stay tuned, I will try really hard to find some time to do some work on the shaft and then updates!!
Sorry for the delay!

Best Regards
Tegheim

[Flash]

Wow. I can't believe you made your own brake disc hats, let alone the suspension from scratch! The old tank Volvo's bring back memories. Personally, I can't wait for the sound of the 4 rotor. When it's all done, promise you'll post a vid of it!!!

Its a sad sad day when a man
needs to try really hard
to find the time
to work on his shaft

Still looks incredible though

O my god. Such nice work. Subscribed!

And I can't belive that the brake-hats impresse you the most :)
They was maybe the easiest part of the whole project so far :P
Just playing you man :)

Welcome back :)

[Tegheim]

Well, the year goes againt darker times here in Sweden. Luckily that means more time inside the garage, workshop and with the computer.
Last week I got Solidworks 2011, and startet tonight to practice. It's not much, but I'm satisfied with the result.

The CAD shows my 184mm Tilton clutch. Soon, there will be blo... cnc-porn? :)

[Silver86]

nice work! subscribed for the awesomeness!

[Tegheim]

The assembly is done!

This is wicked awesome!

[prrex4ever]

You sir have SKILLS, awesome work!

[dream36realms]

my god, my dick is so fucking hard right mow. I wish there were more pics to beat off too.

[Mazdabater]

I can't believe your fabricating the clutch up for it too. That shits insane.

[Tegheim]

Mja, I really don't should fabricate my own clutch :)
I already have this clutch, but you never know when you need to create something.
This assembly was just for training in Solid Works acctualy.

Right know I'm sitting in Solid Works and bulid some Brake Calipers though.
Hopefully I will have my own 330mm Calipers :)

[Tegheim]

Not much, but a start at the front-brake-issue...

Hopefully I will be able do to make my own brake-calipers.

So... just out of curiosity are you making the irons as well as the housings? Or are you pulling those parts from other engines like the 13B/20B? Are you going to offer the EShaft for sale eventually?

I'm just curious as that would stop me from having to re-invent the wheel when I'm ready to do this.

[Tegheim]

So... just out of curiosity are you making the irons as well as the housings? Or are you pulling those parts from other engines like the 13B/20B? Are you going to offer the EShaft for sale eventually?

I'm just curious as that would stop me from having to re-invent the wheel when I'm ready to do this.

No, I will not make any irons or housings. Just the E-shaft and the parts that will need to be done to start :)
I will not sell the shaft then, or the blueprints. You'll never know when you need to have these blueprints in the locker :)

[Mazdabater]

There is a joint over here that sells quad rotors, was very amazed to see one when I was down at WTAC. They do some other weird shit though as theirs is only 50mm longer then a 20b the guy said. I didn't find out how much it was though, he told me that it comes as a package with g/box and shit.

[Tegheim]

Have made my own tool for the little jack into the loosen shaft-parts. Don't know the english word for it.

3.40mm wide and 5.70mm deep. Then put an insert for a lathe there, tada! :)

[Tegheim]

I have now google-translated to explain myself :)



This tool I will put into my CNC-mill. Lock the spindel still. Then I will "shave" of the material inside the lose shaft-parts to make the KEYWAY :)
Yesterday the word "keyway" wasn't in my head, soo I used the word jack ;)

[Tegheim]

This picture maybe help you all understand what I'm about to try out.
This is an 20B-front just for show.

I will now make an fixture to hold the same of mine, the with the spindle off, cut about 0.1mm at time i stages untill i got the right keyway.

[Tegheim]

First attempt!

Have done a keyway in a test-piece. Works fine! And now I will continue with the fixture for the real deal...

Movie on the way!

Did you take special note of how fucking big the inlet port was on the rotor housing side!

Very wide! D shaped and extremely tall too. Was almost identical to my old Peripheral Port 13B from back in 1992!

[730RWHP12A]

very impressive build! i like your choice of volvo too!! my first car was a 122S :)

[MaczPayne]

Nice, CNC broacher!

[Tegheim]

Time for a little update!
Sadly my HTC Desire isn't the best camera in workshop-lights...

Have finally got along with the Keyway!

First, I did new irons to the vise (correct name? Google translate)
They are mounted from the inside with M10-bolts
http://i815.photobucket.com/albums/zz71/Tegheim/My%20Wolvo%20142/My%204rotor-build/IMAG0677.jpg


A hole at 43.61mm, and an Radius 6.0mm to give clearance for Radius 5.0mm on the eccentric.
This is not bored, so the surface is just roughed yet.
http://i815.photobucket.com/albums/zz71/Tegheim/My%20Wolvo%20142/My%204rotor-build/IMAG0681.jpg

Indication of a cam, I have my zero point where I did the fixture, so then you have easy track of the eccentric theory should lie on the X 15.0mm Y0.0mm.
http://i815.photobucket.com/albums/zz71/Tegheim/My%20Wolvo%20142/My%204rotor-build/IMAG0688.jpg



A final inspection of the tool. Indicates the track of the tool in the X-axis, thus I know that it is angled precisely 90grd.
Using the M-code M19 in the machine, so I lock the spindle in the same place every time.
http://i815.photobucket.com/albums/zz71/Tegheim/My%20Wolvo%20142/My%204rotor-build/IMAG0690.jpg



This is what working out, it will actually go much faster, when the cutting speed in such a cut is about 80-120m/min, ie as soon as it will go through the material. Easy as it spins to get the cutting speed, but now the cut stands still. So I drive 2m/min:) or F2000.0 as many may know. Takes just 0.1mm per insert to avoid accidents in my fine pieces :)
wqGoEAxAFRQ



Results! Keyway on 5.00-5.01mm width, and depth with little clearance.

I like this.

"First, I did new irons to the vise (correct name? Google translate)"

We call these "soft tooling" since they're made of softer material that's easy to machine.

Tonight I made a little keyway in the crank, which corresponds to the ones I did in the eccentric.

That did it! The track is 5.01 mm wide and 43.5 mm long.
Easy to forget compensation for the shaft shall be grinded then when you set the depth.

[djmtsu]

Are you friggin milling your own rotors??

Holy shit!

[FC Zach]

Wow! :bowdown:

[Raksj04]

how much will they weigh?

[Tegheim]

I aim at less than 3800-3900grams complete with bearing and gear. It's maybe not very light, but it's my own, and I could easy do some changes and do one more if somethings goes bad.

Aluminium would be very nice, but I know to little about it, and don't wanna take the chance :)

[Raksj04]

well heavier rotors may give you more torque. right?

[My5ABaby]

That's actually pretty light.

S4 are ~4500
S5 are ~4300

[WankelsRevenge]

well heavier rotors may give you more torque. right?

They would take more power and time to spin up though, so any torque gains would be lost.
Ryan

[Libor]

It's maybe not very light, but it's my own, and I could easy do some changes and do one more if somethings goes bad.I would say its very light! But FWIW shouldn´t we talk about moment of inertia? Surely its big difference when the weight is in the middle or on the periphery of rotor? Maybe its not applicable in this example:blush5:

well heavier rotors may give you more torque. right?

No, not even remotely. If anything than it would be less torque.

Its just combustion pressure, rotor face area and effective distance covered during expansion what creates torque minus mechanical losses.

[Tegheim]

Today the E-shaft was left to it first grinding-session. Feels strange :)

I should add that I am not entirely alone in this with billet rotors.
My friend Gustav and I often get yelled at for talking more with each other, then our partner's when we are sitting with headsets and drawing SolidWorks at night:)
We have our visions. I want my 4rotor, and Gustav wants his "tired" 770hk 13B will go a bit better:)

Ok, now I have seen it all.

You are basically building your own, from scratch, 4 rotor engine.

Next time my parents go to Sweden to visit family, I'm going with them to come check out all this madness.

[Raksj04]

I you going to use a oil pan or are you going to go dry sump?

[Whizbang]

this project is far more hardcore than i.

[Tegheim]

It's gonna be a dry-sump. I'm about to design my own dry-sump-cover at the moment. Will try to do as Mazda did and keep the pump into the front cover instead of havin a external pump with belts. More about that later on :)

[Tegheim]

Good combustion chamber sealing is always an issue with Wankels, so I hope you haven't made it worse by making the rotors and side plates multi-piece.

We try this way, and if it's not working. Let's do it again :)

[rgould]

As a fellow machinist and race piston engine builder why make a steel rotor when you can buy iron ones i would think if you are going to go this route use Titanium and save the weight ( half the weight of steel and all most the same strength ) or Is it to say it can be done.

[Mazdabater]

The titanium would probably crack, it's too brittle.

[rgould]

well seeing how titanium is used as compressor blades in turbine engines.
The SR71 Blackbird is 95%+ titanium seeing any where from 500 to 3000+ degrees F at mach 3+
It's used as intake and exhaust valves in all forms of race engines, head studs for Top fuel engines at 8000 hp.
I question brittle. Figuring out the expansion rate for proper clearances at operating temps mint be a little tough.
Machining it's a bitch and aircraft quality billet is pricey.

[Mazdabater]

Given how much I see it crack on aircraft firewalls, I wouldn't trust the apex seal groves, that's just me though

[WankelsRevenge]

Plus, isnt titanium insanely expensive when compared to steel/iron?

[rgould]

Given how much I see it crack on aircraft firewalls
I would say that an apple to orange comparison of a sheet metal fire wall of 0 too thin sheet titanium vs a copy thickness of a cast rotor thickness ( most people try to run titanium as thin as possible instead of the same size as the original Steel part trying to maximize the weight saving)

As an A&P in the US, aircraft firewall in the US is stainless steel per FAA. reg. non military

Plus, isn't titanium insanely expensive when compared to steel/iron?
which is why I asked why make a steel rotor when you can buy iron ones I would think if you are going to go this route use Titanium and save the weight ( half the weight of steel and all most the same strength ) or Is it to say it can be done.

But it was just a question to see the thinking behind the route taken.

[Mazdabater]

Yep, its a bitch to work with. And if you question brittle get some and try and bend it, needs a much bigger bend radius then stainless. It has it's applications no doubt. Studs and valves are a much different application to an actual rotor.

[Tegheim]

The main idea was to SAVE money doing them myself and get the other forefits along with it.
A used Rotor today are about 200USD, the material-cost only for a new one in billet-steel is about 100-110USD. And the work I do by my self.

[rgould]

I can understand that thinking.

With over 20 years of machining a lot of it for high end race teams and programs I tend to not look at the dollar amount but what is the advantage gained from something. I have been told buy people that know me that my out look is skued from the work that I have been involved with over the years.


Hope it works out
Good Luck :icon_tup:

I just ran into this thread...

First, welcome to RCC!

Second, I will be following this thread :)

[infernosg]

im pretty sure turbine blades are a titanium alloy, specifically titanium scandium
Compressor components are made from titanium-based alloys. I know Ti 6-4 is used quite a bit in blades, disks, etc.

What's a typical rotary EGT? I'm thinking all the titanium alloys I'm familiar with would not stand up to rotary combustion chamber temperatures and gases for very long. Titanium is poor in high-temperature oxidation and corrosion. Almost all modern-day turbine components (at least in the industry I work) are nickel-based. Inconels, Hastelloy, Waspalloy and other materials I can't name.

__________________

That I would agree with that on a modern-day turbine components but you also have to remember that modern-day turbines are cooled only by extra air being forced through the insides of the blades so the actual metal temp on a modern-day turbine components is a lot higher than the actual metal temp of a rotor witch is cooled on each rotor face by an intake charge of air and fuel and the internal side of the rotor has engine oil cooling it there by making the rotor more like a piston than a turbine component ( the turbine components never see a cool down cycle once its up and running )

std egt for a race rotary are around 1600 to 2000 deg F
piston race engine 1400 to 1700 deg F pending on tune and application

there are coatings that can be aplyied to the rotor for high-temperature oxidation and corrosion if that would be a problem

No need to explain to me; I design turbine stators (we call 'em nozzles) for a living :) We actually use compressor bypass air to cool turbine components the "cooled" air is actually north of 1000F, typically.

std egt for a race rotary are around 1600 to 2000 deg F
piston race engine 1400 to 1700 deg F pending on tune and application
That isn't as bad as I thought but still too high for Ti. From what I've seen 1000F is about the limit. In the turbine actual metal temperatures can get above 2000F, which is getting out of range for most traditional nickel-based alloys and then you've got to start getting into directionally solidified and single-crystal alloys with protective coatings...

there are coatings that can be aplyied to the rotor for high-temperature oxidation and corrosion if that would be a problem
I'm familiar with your typical TBC's and environmental coatings on turbine components but not in compressors. In the aviation world compressor blades typically are bare Ti or have some kind of anti-abrasion coating.

Sorry to get OT but this is a good discussion.

[My5ABaby]

http://www.kmhkreations.net/wp-content/uploads/2011/09/dollar-sign.jpg

I support the cheapness. It's cutting weight and costs less than a used rotor. Win/win.

Yes the rotary runs hotter than a pistion engine with its EGT temps But it is still a water and oil cooled engine witch still goverend bt some constancs

Was not trying to o fend by explaining the turbin cooling. You never realy know the person background but it also lets outher people know what we are talking about
I would say that the running temp of a rotor would be less than 500 deg F if it's that high. The Apex spring, side seai springs and corner butten springs would not be able to keep there strengh at temps higher than that. Another point would be that a rotor beinging hotter than that the oil on the inside would want to cristlize due to the heat. Also the rubber oil control seai would be more likely to fail as well.

An alum piston melts at around 1200 deg F yet a race engine see EGT of 1400 to 1700 deg F and the piston does not melt if tuned correct thanks to the water in the block and the oil in the sump keeping operating temp in a range of 180 to 230 deg F for both water and oil. The same is true of the rotary yes the EGT is higher and the parts are hotter but they still operate in a range of 180 to 230 deg F for both water and oil.

But it's good to have this discussion

22Kg startweight.
About 19.5kg will be removed :)

[Tegheim]

Now I've cleaned up after me and takes weekend.
This took a lot longer than I guessed. Then it's always so well with the first, but had probably hoped for smoother processing:)
Has anyway tried to run a finishing the outline today. Is not quite satisfied, however, it does not matter for the function. Has left 0.5mm for further testing:)

To be continued in the Christmas Holidays!

[RICE RACING]

Your talents are wasted on rotaries and volvo's!

You should be working on making the replacement space shuttle :)

[Tegheim]

Haha, I don't know how a space shuttle works?! :P

Tried a little bit smaller step this face. What do you think about the comp-ratio in the bottom?
Good or silly...?

http://i815.photobucket.com/albums/zz71/Tegheim/My%20Wolvo%20142/My%204rotor-build/IMAG1030.jpg

[FerociousP]

But you lowered the compression ratio by engraving the numbers!!! Its pretty silly but as long as it doesn't cause any "hot spot" problems then why not...

[Tegheim]

Haha, you didn't like it ;)
I have 0.5mm left to cut, this was just a fun test ;)

[My5ABaby]

I think having the compression ratio somewhere on there is an excellent idea. Where you put it is up to you... it's different there, but not bad.

[Pete_89T2]

I think it's a great idea, but I'd recommend not doing it on any of the combustion chamber surfaces. The edges of those numbers might become localized hot spots, that could lead to pre-det issues.

BTW, Awesome build! :cheers2:

[Tegheim]

I'm thinking about making my own centerplates, billet of course. And in steel at first. What are the biggest issues that stock centerplate have?
This is just a thought at the moment... :)
Could I improve the cooling or something else easy? The front and rear would probobly be stock.

[Tegheim]

Now finally the production has begun for real ... I had never guessed that it would be so much preparation work on these. Do they look simple, but have been scratching my head once or three times ...
On top of all this, a revision of the CAM program take 5-15minutes of the heaviest pieces.
3st roughing 3D pockets from one direction is about 1500kb large program. Times the third Times two ...
Milling time, we will not even go into. It takes time:)

It's accually kind of fucked up that we don't have aftermarket-rotors with human prising. The piston-guys could pick and choose how ever they want. I also want that without sell my mother.

Whats the cost of the materials for this project at so far? Id imagine one of those gigantic metal discs costs an arm and a leg.

[Tegheim]

Actually each rotor-material costs 750SEK, and that is $90-100.
Quite cheep I think, as the HM-endmill of 10mm dia that I use for the pockets costs about the same :)

[Tegheim]

Built me an lightweight-engine today that is alot easier to get in and out of the car when i want to do some measurements :)

Wow really? Thats awesome dude its probably cause you know people lol I bet if I tried to buy that it would be more than 100 bucks.

[Tegheim]

No, the materials aren't the expensive. The expensive is the time in the machine.
If I would hire myself at work, my boss would charge about 1200SEK/hour, thats about 170USD/Hour...

[Pete_89T2]

About how many hours of labor are involved in making one of your rotors? Out of curiosity, I checked what rotors cost at Mazdatrix. A new rotor from the Mazda factory for an FD costs about $700 US dollars; you can get one a little cheaper shopping different Mazda parts dealers, but that's a good reference number. If you & your boss can get the unit cost per rotor below that figure, you might have a great business opportunity here.

[Tegheim]

I don't know much hours involved, but theres a couple...
Mostly because the machine I'm working in aren't high-speed-machine.
I'm limited to 4000rpm in the spindle.

Today I worked in the wrong direction :)

If it all works out like you plan and it can take a beating, you should start to produce 2 and 3 rotor engines for the consumer market.

I would gladly shell out the cash for one!

[Tegheim]

I'm afraid thats never gonna happend. I think the part would be to expensive, and I don't know how to find time to do it :)

But, if you remember, I can't move the brakedisc futher in.

[sa22c]

Hi,

I have a few things to input into your build.

#1 Use LDR rotor recess rather than MDR. LDR requires less fuel to idle and makes more power. The only disadvantage of LDR is that it promotes higher combustion temperature and thus increased NOx emissions which is why Mazda stopped using LDR in 1985.

[EDIT] If you make your engine side ported how are you going to deal with rotor 2 and 3 having different port area to rotors 1 and 2. Sure you can port the timing angles to all match but the runners will be considerably different.

[Tegheim]

Whats MDR and LDR?

It's going to me PP :)

[sa22c]

This is an LDR rotor.

http://img.photobucket.com/albums/v227/diabolical1/Engines/12Afrontrotorpolishedvi.jpg

[Tegheim]

You mean that the combusion is not the same all over?

[Pettersen]

It refers to the shape of the combustion chamber.

LDR = Leading deep recess Good performance high emissions.
MDR = Middle deep recess Compromise to get down emissions.

[Libor]

It refers to the shape of the combustion chamber.

LDR = Leading deep recess Good performance high emissions.
MDR = Middle deep recess Compromise to get down emissions.

Well, I have seen too much data on this stuff so I forget most, but looking at "Recent Technology Development of High-powered Rotary Engine in Mazda", its clear that MDR design produces highest BMEP from all tested variants, especially in the top-end. Note: this is with both spark plugs. Second best was "leading flat" recess and LDR design was third as far as power goes.

With leading only ignition, leading flat was best and LDR/MDR were about the same at the top-end, LDR slightly better in midrange, but both considerably worse than leading flat variant. But the point is moot since the most people do use both spark plugs.

IIRC R26B and 13G also has MDR rotor pockets. Maybe this desing has bad name due to Renesis rotors, but their problem probably lies much more in inferior gas sealing - low dynamic compression.

[Tegheim]

Huh?!

Have changed my Cad a little. Moved the bracket 50mm to the center of the car, to gain 61.5° angle on the coil at rideheight, and 66.0° angle at full bump.

This is what it looked lite before the change.

To be sure that the caliper and disc are in level.
And also, to get a fine surface to attach to.

Amazing, I have worked with CNC in the past, but this is well over my head... Excellent build thus far! Cant wait to see it finished!!

[RICE RACING]

Reminds me of designing and building fabricated uprights (and all other parts!) for our Formula SAE cars back and the University I worked at ......... so so so many hours of work and I can relate to what you are doing!@

Keep it up.

[Weltall]

This is mind blowing! Hurry and get this done so I can buy one from you to put in my Opel GT!

[Yoshi]

This is quite the excellent build, sir!

[vex]

I want to make sweet, sweet love with this build.

I may have to pick your brain in a few years about some of your engine stuff. Consider yourself warned.

[Raksj04]

I still wish I had half of the skill to do this.

[Tegheim]

Thanks guys! I will try to keep the pace now when I feel the flow.
Some days, I just wanna blow the whole shit up in the air :)

[Tegheim]

Today I did a mockup to see that the coilover-lenght could ba about right, and that the angles looks good in the car.
I also got som used rear tires, also to mockup and make sure the fit later.

I think we all feel that way with a project sometimes. Take a week or so off, have a beer, or two, or three, or.... with guys that are tracking their cars. Run a few laps of Gran Turismo, etc. Bam! good to go, ready for more work. :auto:

I see that you say "four rotor" build. how about some images of the motor build?

[My5ABaby]

I see that you say "four rotor" build. how about some images of the motor build?

Look at the whole thread.

[Tegheim]

You got to have a car to put the engine in. There's alot of time there!

[Mazdabater]

Looking gorgeous as always buddy, do you have the shaft back yet?

[Raksj04]

So how much of this car will you still be able to call a Volvo?

[Mazdabater]

I'm going to assume the badge. Lol

[Tegheim]

On the outside the car will look original, but rather low, about 150mm lower than stock :)
But Volvo have thought about this idea a looong time. This Badge the had on the P1800-model. I think they wanted to say something :)
