pics of my 20b FD

[vincentrx7]

Just got some pics taken after I washed it. Sorry but I'll have to make several posts.

[vincentrx7]

Instead of multiple post, try the link if you want to see more pics. There are also some pics of my TT BMW 335i.

Looks good, glad that trans is working out for you. Look forward to seeing you in the fall at the Speed For Sale Shootout.

[Nutsid]

Great looking car. I like the BMW as well.

[Phoenix7]

nice! I like the lip. Great job. Don't forget to enter it in next month's ROTARY OF THE MONTH Contest.

[vincentrx7]

Thanks for the compliments.....

Bestiality should be illegal. How much power are you putting down to the ground?

:uhh::confused:

[vincentrx7]

It made 470whp at 10 psi and 560whp & 414 tq at 14.5 psi.....

[Nutsid]

It made 470whp at 10 psi and 560whp & 414 tq at 14.5 psi.....

4.5 psi made almost a 100 horsepower difference?!?!?!??!?!?!??!?!?!??!?!

[vincentrx7]

I was off, it was 14.92...call it 15psi...not 14.5

You question the difference but 15 psi is 50% more than 10 psi.....

[My5ABaby]

So............. I approve of this thread.

Thanks Mr 5A.
The 20b is a pretty strong engine.

[KaiFD3S]

Who did the install...I have been thinking about going this route...but just so undecided due to the amount of work...

[Herblenny]

This car was at the DGRR 2008. Beautiful car and well put together!

Kai, I believe RX7store did the install.

I think I also have few pics of this car from the event..

Yes, RX7 Store did the install. Checkout their website
www.rx7store.net. They actually have several in progress pics of the build.

They have 1 or 2 more 20b jobs in progress now. I am very happy with the work they did.
As you'll notice, there are a lot of 20b project in progress but few 20b's on the road...that is because there is a ton of little things to do that you just don't think of going into the project. I would have never completed the project if I did it on my own. I have a demanding job and a family so the only way I could have the car is have someone else build it. PM me if I can help in anyway. Good luck.

[sumdeus]

Yeah, I saw it at DGRR, sounded beautiful too.

Sigh... I want it.

[GorillaRE]

4.5 psi made almost a 100 horsepower difference?!?!?!??!?!?!??!?!?!??!?!

On an engine with a high VE it is not uncommon to see over 15hp-per pound of boost (in this case 18hp). There are a lot of other factors and though you most the time see gains of 10-13hp-per pound it IS possible.

[GorillaRE]

You question the difference but 15 psi is 50% more than 10 psi.....

It doesn't work that way my man...... :icon_tup:

[Lotte]

how much did it cost to build the 20b at rx7store?

[vincentrx7]

It doesn't work that way my man...... :icon_tup:

-J

You are right, it is only 20% difference...... I would be hesitant to even use a rule of thumb since so many other factors influence hp other than boost such as AFR, timing you name it....basically the whole tune...... I just figured the guy posing the original question was calling me a liar. Thanks for the correction.

[vincentrx7]

how much did it cost to build the 20b at rx7store?

You should call Jason. I'm not sure what they are quoting now. They are building 2 3 rotor engines now. The other thing is it depends on what you already have such as intercooling, radiator, etc......

[sk8world]

very clean!

[KaiFD3S]

Very nice, I soon to will be joining the 20B club...Can't wait...May take a couple years though to finish...LOL...

[Phoenix7]

you ARE going 20B!?!

[GorillaRE]

Why not?......He's got every other mod :)

[Phoenix7]

well, I asked him for an interview :suspect: What he'd do differently if he were to do it all over again and he said 20B. SO it's great/funny to see that he IS going 20B.

[Dan Devin]

Efficiency gains in rotories never cease to amaze me when increasing airflow.
My built 3-rotor with a Borg-Warner S-400 turbo acheived a 100 horsepower gain on the dyno at 17psi when the exhaust system was simply removed at the downpipe. This was a quality exhaust with no cats, not stock! My NA 2-rotor 6port gained over 40hp by removing the cats and replacing the exhaust with an Apexi GT N1 and a K&N intake. That is on a motor that comes stock with only 148hp!

[vincentrx7]

Wow....how loud was the 3 rotor? On the flip side, I thought I would restrict hp with my airfilter but it dyno'd the same with and without....I have a 4 in exhaust TB but I do have a resonated midpipe and a CB.
Looks like you are new to the forum....Welcome.

[Dan Devin]

Thanks for the welcome. My down pipe goes from 5"down to 4". After seeing the dyno results I put an electric butterfly y pipe at the end of the downpipe and I can open it up with the flick of a little toggle switch on the console. It sounds like the hounds of hell! Unfortunately I have some motor issues right now that I haven't had time to investigate.
I also have a second gen 3-rotor with a whipple supercharger and an 850 cfm Mighty Demon carb. It is a fun car, a very simple, dependable set-up that makes a great all around car. I'm almost 54 yrs old and I shock the heck out of the boys around here when I just walk away from their prized Evos, WRX's, etc. -Love your car-very sharp!

[vincentrx7]

Were you at DGRR this year with a white FD? Sounds like you have some really cools cars. Cool to see another older guy in the import scene.

[sk8world]

on the old guy note, we used to have another 3 rotor guy that spent the winters down here in AL. Dick Lambert. Have not heard his name around in a year or so. I think Dick is in his mid 60's. I heard he sold his CYM 3 rotor but still has his white drag FD.

[Dan Devin]

Yeah that was me Vincent-I thought your car looked familiar.

Now about the "old guy" references; nobody that owns 6 RX-7's and 5 20-b motors can be old. Just think of me as a mature juvenile. Just ask my wife!

[vincentrx7]

Actually I'm Bobby....I live in Vincent. I recall you were just finishing the install and didn't have it running yet. I remember the BW turbo that was huge. One of the guys with you ended up buying an ignition amp from me while I was there. Planning on going to DGRR in '09? You should consider the Speed for Sale event in October. I'm planning on trailering my car down for that. Maybe I can get my wife to bite on the "mature juvenile" line. She just thinks it is a mid life crisis.....

[Dan Devin]

Bobby,

Based upon my experience you can forget getting your wife to change her mind about your car hobby. My wife cannot see any intinsic value in it at all. Yes, that was Brian Gray that bought your amp-he is my local partner in crime and the one who told me about DGRR. What, and where is, the Speed for Sale event?

[vincentrx7]

Look on this forum in the vendor section for the vendor Speed For Sale. In that section is a thread on the event. It is in late October..... Check it out and let me know what you think. Looks like there are going to be some really fast cars there.

[gmonsen]

VincentRx7... Hi. Thought I'd see how civilized it might be over here. Nice to see your car. I am really thinking of a 20b East Coast meet.

Gordon

[vincentrx7]

Good to hear from you....How many RUNNING 20b's are on the east coast?

[PortedRotorTuner]

Very Nice 7.

[BLK FC3S]

How many RUNNING 20b's are on the east coast?

Quite a few just in Florida. I can think of 5 just in central Florida but I'm sure there is alot more down near Miami. Deffinitely more here than the west coast.

[vincentrx7]

Seems to be more and more interest in 3 rotor conversions these days.

[BLK FC3S]

Thats because the 4 rotor engine isn't available readily.

[hsitko]

What turbo did you go with? Secondly what were the deciding factors that lead you to pick that turbo? Only reason i ask is, it seems like you dont see peak boost until 5700 rpm. Seems like that could likely be improved a great deal, depending of course, entirely on what your goals for the car are. Really nice looking build. You definitely have a 7 to be proud of.

[vincentrx7]

I have a PT74. It has a .96 or .98 A/R....funny that when I was building it people were commenting about having a turbo that is too small....The boost could be a little more responsive if I tweaked on the boost controller....I will say that the power comes on really smooth and as a result I don't have any traction problems. Even when I turn the boost up to 15 psi I stay hooked up in 2nd gear....Oh about how I picked the turbo. I didn't. I bought everything (engine, ECU,clutch,ignition, turbo,exhaust..etc.) as a package from a guy that had been collecting the parts to build his car. It was a deal I couldn't pass up and I ended up with what he picked out. I've been pretty happy with it to be honest...not sure I would do too much different. Thanks for the comments.

[Brent]

Your car looks great Bobby! Very clean subtle exterior... and the 20b under the hood. Look forward to seeing it at the SFS event here in a couple of weeks. Will you be running it on the road course or 1/4 mile? just spectating?

[vincentrx7]

I'm doing both. I built it to run it! I'm 10+ hrs away so I am trailering it down. I won't be the fastest on either track but it'll be fun. I just got my new transmission put in tonight and got an engine torque brace installed. I hope this will help my 1/4 mile times as I have been shifting from 2 to 5th gear. I also got my AI working. I'm looking forward to meeting everyone too. Make sure you introduce yourself.

[StreetRx7]

Very Nice 3 rotor FD... :driving:

[HDP]

Wow, it's up for sale?

[sk8world]

Wow, it's up for sale?

\??? were does it say that?

[Charlie Redden]

I thought I saw it on ebay...or autotrader

[HDP]

Click the link in his signature...

[sk8world]

ok.. wow 54k!

[HDP]

Yeah, that's what I said. So, anyone going to volunteer info on why it's up for sale?

[sk8world]

54.5 reasons!

[HDP]

Nah, that's just an incentive... what's the REAL reason(s).

[David Jerome]

He is partners in a high end car sales business, Im sure it just looks good on the site being for sale. Years ago it probably could have brought around $45-50k, the market just isnt there for any car right now.

[sk8world]

I here ya... I am so glad I unloaded my Porsche last year...

[vincentrx7]

I haven't looked at this post in a while......About it being for sale....everything is for sale you know. BTW, I dropped the price to $53.9...LOL. You never know when someone w/ money would want a unique car to take to a rotary event or something and needs it quick. It would break my heart to sell it but like I said, if someone really wants it, I would sell it. Like David said, it does get people to our website to look at the other cars we have in inventory for sale....www.sesportscargallery.com if you're interested.
HDP, no underlying reason. I love my car.... I like having something unique to drive and take to events like the Speedforsale event they had in Alabama this year.
