Dyno results from my other car, not my Mustang.

It's a 1997 Toyota Supra, completely stock engine with a big turbo replacing the stock twins. Only thing taken off of the engine was the intake manifold to install larger injectors and fuel rail. It makes the 500rwhp my Mustang puts out look like childs play.



Driving the car is very scary to say the least. Even with drag radials, it still spins the tires in 3rd gear at over 80mph and will break the tires loose in 4th at 110. I'm taking it to the track this friday and hope to run at least mid 10's at 138+ mph.

How big a turbo is it? The torque curve doesn't look all that peaky.

It is a 74 mm compressor with a .81 AR. The internals are forged but the pistons are not. It's really not too laggy surprisingly and the power band isn't really that short. From 5000 rpm to over 7500 rpm(not shown on this sheet) it's over 600 hp. That's over 2500 rpm of 600+ horsepower. Comparing it to my Mustang's dyno, the Supra has a much wider range of higher horsepower, just that the Supra's is at lot higher rpm.

Bigger turbo + fuel rails= 700+ horsepower

How?

I know that Supra's are dangerous but damn.

Specs on the car:
1997 Supra, stock motor
Sound Performance SP74 Turbo kit and Fuel system with dual pumps and 95lb injectors.
Tanabe Racing Medallion exhaust
AEM ECU
Greddy 3 Row front mount intercooler.
RPS Carbon/Carbon clutch.
HKS Twin Power DLI.

I think that is about it in terms of performance upgrades.

Also, this was at 29PSI, if I had a stiffer wastegate spring, I could have ran a few more pounds of boost and probably been 730+. This actually pretty tame considering other Supras out there. Once I get different cams and do more tuning(as it's conservatively tuned right now) it should be close to 800 rwhp.

How long will the stock block last with that much power?

Jeremy, it should run 10's fairly easily as long as I can hook up. With the AEM ECU, I've got a 2 step and I can build about 6-10lbs of boost at the line. Launching like this on the street, the tires go up in smoke, so I hope I can get it to hook on the BFG drags at the strip. I'm hoping for upper 130's and possibly low 140's if I get a little more aggressive with the tune.

Venom,
The stock internals start to become a concern around 825-850rwhp. The stock block and internals current record is 958 rwhp on nitrous, and 912 rwhp all turbo.

my guess is mid to high 130's for mph. say 137-138mph. i know that down here at our local 1/4 mile track, the battleground supra ran but not w/ the 900rwhp tune but the ~840rwhp and it mph'd at 142.9 on a 10.3x pass. that being said, i think you'll do mid to high 130's unless the weather is phenomenal and you absolutely dead hook. these are just a guess based off the other car i saw run though, so good luck and let us know how you do b/c i'm by far no expert on possible e/t's and mph's. anyways, nice car and let us know how it goes.

I'm not very Supra smart, but did you have to put in the air, spark, fuel tables yourself? what steps did you use to make the tables? Did these cars ever use a Mass air setups requireing a meter or is it all speed density kind of stuff?

92fastlx,
I'm hoping for 135-136 at least. The car will make more power on the track because of the increased load actually allows me to make 31 lbs of boost as opposed to 29 on the dyno, plus more air will be going through the intercooler to cool the incoming charge. Temp should be in the low 60's high 50's tomorrow when I run, pretty good weather for making power. I'll let you guys know how it goes.

Zeet,
AEM provides base maps that have initial tables set up. Pretty much fine tuning of the base maps is what is needed once you get it set up to run with your injectors and sensors you are running. A stock ECU supra uses a MAF, with the AEM ECU I've converted to Speed Density.

AEM makes these ECU's for mustangs now. I'm thinking of putting one in my mustang, as the possibilities with it are endless.

Great #'s Axoman. Is the SP74 the GT-Q or the H.O. "pimp" trim. I have an MKIV myself (94' 6-speed) and have a single sitting up in my room going on ASAP. It's just a weedwacker turbo compared to yours though!

Boost? ...Yes please!!!

pkstang - Thanks, I'm also Axoman on Supraforums as well.

Troy, just the GT-Q version, I may go to the HO though later on. What are you putting on your MKIV?

Your Supra is definitely impressive. I wish I could afford one of those.

Man, there must be something REALLY WRONG with my friend's Supra. He only made 586RWHP @ 30psi with his combo.

Mods:
Stock bottom end
Custom bigger intake
Wilson 80mm TB
Custom Intercooler (I think it is way too small for his combo)
GT74 Q Trim
HKS 272 cams
MicroTec ECU
850cc injectors
ClutchMasters Stage III kit
Dual fuel pumps
HKS GT Wastegate
Greddy Type-R BOV

Boosted - I'd say something definitely isn't right with your friends set up. That is very low. The IC could be restrictive, but I wouldn't think it would be that restrictive. With 272 cams, he should be at least upper 700's to the wheels.

I ran the Supra at the track on Friday night, didn't do near as well as I was hoping. I couldn't hook up at all, 60 ft's usually around 2.4-2.5, and pedalling it through the first 3 gears. At only 25PSI I was able to run a 12.0 @ 135MPH. Upping the boost only made traction worse, and I ran slower. If I could have hooked up on 31PSI, I think I would have been very close to 140 traps.

Nothing to be ashamed of. Practice makes perfect. Your engine is very clean. I like it.
