What's the octane rating in New Jersey? 91 or 93? If 91, I'd play it safe and not run leaner than 11.5 ( I aim for 11.3 with 91 here in AZ) if you want to keep your motor for long. Also, the compressor choke point on a GT35 is just North of 500 HP, so you're getting pretty close to being maxed on that turbo. Still, great numbers.

the car was tuned by steve kan at first, it blew up after maybe 3000 miles on 15 PSI, Then it was rebuilt with new housings and the map was tweaked (at distance) by Chuck Westbrook to remove some timing since it seemed to be too aggresive and it was probably the cause of the fresh blown engine. So the map was made to be safe, not for performance.

Hi guys, this is my old car.
The results are impressing! I'm really happy to see these numbers! I would have liked to keep it but the timing wasnt the best for me.
Happy for you Matt, it's a fantastic car. A real rocket!
BTW : I'm back in a FD

Hey Max! I did clean up a few things with the car since I bought it from you, but nothing much... solid engine and diff mounts, diff brace, removed P.S., replaced the 13 lb spring with a 10lb spring in the wastegate, fresh plugs (your's were very nasty ) and few other things.
So... I took the car out today and set the boost to 14/15 psi and pulled some 2nd and 3rd gear WOT runs. The AFRs never went above 11.3/11.4 all the way to redline. Made it to about 6k in 4th and never saw higher than 11.0. I'm pretty sure the car's tune is just fine. It feels fast as hell, easily the fastest I've been in - passenger was scared shitless as well .

We should meet up sometime soon, Max's old FD is clean as hell and I wouldnt mind seeing it again. Also, I think I have a spare stock jack laying around as well.

Wow!
I knew this car had great potential. I'm thinking of making a nice setup on my new one, but probably or 1-2 years depending on the job.
For now it has :
new rebuild (stock)
full exhaust
pfs intercooler
power fc
intake
apex'i avc-r
ACT clutch
Pettit AST
Fluidyne Rad
New rebuilt tranny
etc.
What about a 500R or a GT40R on a nice ported engine
Rich : my ex car is really nice... light and fast rx-7.
Matt : could you send me some pics of my old car? did you take some ?

Nice numbers. This gets me excited for my car when I get done. I have the same kit with a 82mm comp, 74mm turbine. I will not be running a ported engine as you are, but I hope to get numbers close to your numbers.
Hope you can get all the bugs worked out and get better numbers.

Despite the power curve, the turbo is great on the street. I can drive it easy or aggressive and the power feels very controlled until about 6.5k. Then it's just scary fast... Also, the power keeps going; I have to consciously look for redline since the power keeps climbing linearly.

Few people believed the results from this turbo, so yesterday I redyno'd in on a Dynapack.
It made 478 rwhp and 369 ftlbs of torque (SAE corrected) pretty consistently over 3 or 4 4th gear pulls. Boost spiked to about 18 psi though - but AFRs were in the mid 11's and the knock was low. I essentially turned my boost control off and was running off the Tial 44mm wastegate with a 13 lb spring. For some reason, 4th gear pulls on the dyno makes this car over boost at about 7k rpms.
So, between these results and the earlier results on a more optimistic dyno (Dynojet) I would guess this car is putting down a comfortable 450 rwhp at 15 psi. I'll post dyno graphs later.

impressive... Hopefully my a-spec T435r kit w/ a 1.06 hotty will be dynojeted around Christmas. Putting it together right now. I'll have some pics up soon of the progress..G

Congrats man, when can you post the sheet?

Rx7 specialties engine with large street port and 3mm seals
550's/1680's injectors
Apexi PFC tuned by dave at KDR
HKS twin power ignition
NGK B10EGV plugs
A-spec GT3574 kit with long runner manifold
Tial 44mm WG
No a/c or PS
ACT SS clutch w/ stock flywheel (I need to change that )
Solid motor and diff mounts w/ diff brace
A bunch of other stuff... but that's about it for the power.
Hey rich, my wife and I just had the baby on Thursday , so I haven't had time to get my scanner and new computer working, but I'll post it as soon as I can.
You should post it, if you got the time - that was LOUD .

"I'm sure I'm pushing it for pump gas, though . No water or alcohol injection as of now..."
you are making 475 rw or 550 flywheel, actually deduct 10 from both as SAE hp is the norm. anyway so 465/540 on 93 octane pumpgas????
that's 3.4 hp per cubic inch. i don't care what AFR you are running. you will either have warped apex seals or broken apex seals real soon.
i suggest you pedal your car a bit until you have AI.
nice going BTW, i like your turbo. also how about a real dyno sheet w rpm at the bottom done in SAE.

I run the car on the street at 15-16 psi, for some reason on a dyno I cant keep the boost below 17/18 psi in colder weather (running off a 13 lb wg spring). That's why I inferred the turbo to make around 450 rwhp at 15/16 psi.
Do you think at 15 psi w/ 3mm seals the car is unsafe? It drives great .

wow, very impressive numbers, i am just searching for info on the GT3574 kit from A-spec, and i believe i will order one after reading these post. sorry to bug u, does everything fits from a-spec and what else do i need except for custom IC piping and intake, in order to complete a single swap? and for the tuner mentioned here (Dave,steve and chunk), can i just buy PFC maps from them or would they come up to Canada to have my car tuned?
