My RX7SP build up

[JhnRX7]

Nice! Now its time to do the front to match

I see you have what looks like multi piece brake rotors... Are those Spirit R sized brakes or the original smaller size? Were there any changes to the braking system with the original SP?

These brake rotors are original SP developed items (or M1020 prototypes cars from 1994, which were then farmed off to the production SP Australia cars). * years later they were brought back out for the Type R, Bathurst and also the Spirit R and Type RZ RX7's.

The SP has a different front brake caliper to standard and reworked ABS to match the braking system size.

The brake rotors are simply the stock sized units but vastly better than the std Mazda offering, I run Project Mu rotors front and rear with Project Mu pads. The car makes so much horse power and velocity that I broke a rear disk rotor last time I had it out on a race track! they just cannot handle repeated high velocity stops at full braking power. Sure if it was like the stock SP with only ~350bhp in race trim it could do it for 12 hours straight like they did in competition, but with now 600+bhp not a chance

Here is a great series of video's on Japs and Rotaries and other inferior cars, pay particular attention to the PANSPEED as dynoed on dynapak dyno..... LOL I was making 478rwhp on 1.2kg/cm on a street port 10+ years ago with bush bearing T04S @ 1.2kg/cm on a 2nd gen T2 engine block http://www.riceracing.com.au/water-injection.htm , V's them with T04Z, bridge port and FD 13B-REW motor ...... pretty shit power band to match on the bridge port too!!! and needing race fuel to do the peak 503 rear hub HP

You will also notice the Cyber EVO doing a massive 343rwkw or 460PS on our dyno dynamics system @ haltech .......... LOL if you ever were in doubt as to how low Australia dynos read compared to exaggerator 3000 units you run in America LOL Remember ND4SPD RX2 = 448rwkw or 602 rwhp!@!!@ water injected!!!

Interesting viewing indeed!

My RICESP on 1.85kg/cm with stock std 13B-REW would easily out accelerate these "worlds best time attack powered machines" despite it weighting allot more LOL all on normal pump petrol and RR WATER INJECTION High boost runs coming to a forum near you in 2012 FACT v' FICTION LOL

Wtac machines aren't all just about power though, I have alot of respect for that cyber evo the things incredible.

The only thing incredible is how a piece of shit like that in engineering terms is so well thought off LOL.

It is a full on nugget in many respects, engine wise in the majority it's a joke, honestly The turbo is a full on piece of shit in the extreme! It shows you just how fucked they are to protest a real engine like in the Sierra Sierra EVO because it was 30+kph faster down the main straight at Eastern Creek < Now power is everything

WTAC really is just a hack class for drop outs and plastic trophy racers, nobodies in the scheme of things honestly. It's far too hyped up in the extreme really..... There are hundreds of other cars in all sorts of classes that would totally wipe the floor with these pieces of shit. European Rally Cross cars 10 years ago were racing reliably with 850bhp to 950bhp from 2lt turbo 4 cylinders!!! IMHO Porsche ran the 917/30 in endurance races with 1100bhp!!! in the 1970's!!!! makes WTAC look like a chump "sport" which it is honestly
Fuck Toyota ran a 3SGTE motor at 2.1lt with single turbo in American Endurance race trim @ 950bhp! in 1992 with an Atari Game Console for an ECU! passing 4 rotor R26B powered cars like they were standing still!!!! *its all been done before to a much much higher level* BMW ran stock block 4cyl 2.1lt turbo in the same IMSA series at 900bhp! on mechanical injection! in the mid 1980's!!!! same engine they used in F1 that proven to make over 1300bhp in high boost form @ 1.5lt capacity and only 10500rpm!

I do like that back yard nothing high school drop out workshop owners and groupies can run cars though. Eventually the novelty of Time Attack will filter down and you may see some serious engineering and talent come into it. I for one wont be impressed till you see 1000+bhp 2lt turbo cars running around, then they will be where real professional were at 30 years ago IMHO

These cars should really be in the ~1300bhp and all 4WD range to be up to modern standards and technology, there is no reasons why not, except there is no real engineering "talent" there to run such cars as they are ALL in real forms of motorsports across the globe..

Anyway of enough talk of other cunts, here is some more angles of RICESP, the new rear tires look SICK! I love the way it sits. And the mega motor set up, cant stop looking at this, hard to believe something so stock looking (for a genuine SP!) makes so so much power!!! From concept to proven performer

[FC3S Murray]

Damn that youtube vid you posted in the Fd section was amazing. That is one FAST fd3s!!!!! Now post yours dammit!

Yes it is! it btw is the only other "credible" documented RX7 to post up anything like proof of its "claimed power"... a total credit to the owner builder

In the new year I'll do up a few video's, might even get a new HD camera? and work on a few different angles to capture the immense speed of my own RICESP since I know how much all you boys love seeing real rotary street cars that are fast and reliable part of the motivation is to inspire others and also show them while at the same time debunking allot of the bullshit and mis information sprouted out by nobodies/high school drop out shop owners/self proclaimed experts on rotaries telling you that you need extra dowels, porting, C16, E85, GTXYZ123 turbo's, billet dildo's (insert any other bullshit here) to have a fast and durable car The irony of all those < is that non of these cunts have ever produced a real road car that is durable or as fast!!!! *token BS rwhp dyno sheets aside LOL*

So a full year on and covered another 6000km (to date: all up 8200km) of testing/racing/top speed trials.
Summary: Every drive has been quite high load 90-140 testing probably around 400 or so of these tests, many 100-200kmh & 60-130mph runs (3rd to top of 4th gear) and a few top speed runs (on special test track ). Last 3000km at ~500bhp level @ 1.53kg/cm Boost level.

I did one intermediate compression test between the 1800km and this one today, but only wrote those figures down rather than taking a photo/proof. They were close to the ones today.

Rear Rotor


Front Rotor


This test was fully dry (engine run till out of fuel) and EGI disconnected, First one cant remember but I think was not as "empty" of excess fluid, this makes a high difference to rotary engine compression readings FYI.

Anyway she is not too bad, I did not think it would hold up this good especially given its a mobile test bed each and every single time it gets driven.

I have it at its new boost level of 1.7bar (around 1.75kg/cm) and it is a rocket see if she can make another year of punishment

So here is my once annual compression check up of RICESP (3rd year now! ~20,000km covered!)... This is after using the car as my daily driver for over 6 months! and also all of the higher boost settings and reconfiguration I have done over the Christmas break

Beautiful car - glad I found this thread

[JhnRX7]

Rice,

How do you like the Ohlins Flag coilovers? I found a used set for sale that I am trying to get ahold of. I know they will be great for the track, but I'm curious how they are suited for street use.

My car is a street car 100%

These shocks are better than in my daily FJ Crusier they are perfect, spring rate at 14kg/cm is very nice for the road too (and you need it at this power level fwiw).

In summary EXCELLENT.

[yzf-r1]

Isn't that 14 kg/mm (780 lb/in)?

[RICE RACING]

Sorry I was thinking boost pressure units hahaha.

Yes 14kg/mm springs.

These are great on the street as the suspension never bottoms even on higher speed undualtions at high power. I ran 8kg springs before in some Tein suspension and it was crap cause as soon as you went over big undualtions at speed the suspension would bottom out.

The ride "quality" is all in the shock absorber setting, the Ohlins I have are perfect for the street when you set the bump and bound correctly.

Here is some pics of the IC spray valve, takes fluid from the WI tank, and some pics of the beast

Love it more and more each day, performance is sick as! and it drives just beautifully, power is getting a bit silly on the street though
