Not really into dyno-ing my car. But was just curious on how much estimated power i actually do have. I have a 89 Fastback. Untuned

-SR20DET Stock Motor-T28(S15 Turbo)-S14 Turbo Elbow-3inch Down Pipe(was told from person bought from), but it looks bigger-Tanabe SMR 3inch Catback Exhaust System-Walbro 255 Fuel Pump-HUGE FMIC-Drifting Tuned transmission-HKS SSQV BOV

Was wondering how much HP and TQ i have at 8psi and 16psi of boost

at 8 psi, around 230whp

At 16psi, you'd run so lean on your stock injectors that you'd probably destroy your motor.

Oh, also, big LOL @ "drifting tuned transmission"

8 psi I seriously doubt hes make 230 whp. I made 227 on 10 psi on a T4 with no ignition timing. 8 psi Id say 220 with an agressive tune.Id say on 14 psi which is very doable youdmake around 235 whp

A friend in need of a bigger turbo and fuel injectors, is a poor friend indeed.

Of course he does...he has a drift tuned transmission...

But really I think the drivetrain mods are missing. He may be making that 230-240 at the crank, but what kind of drivetrain upgrades you got?: rear end, clutch, flywheel, what about pulleys, or any unused accesories...those things will find him some more power. That is if you are trying to see what you are putting down as apposed to what you make.

Got a lightweight flywheel(cant remember the name, the dude told me when i bought the car). i got a Excedy Stage 3 Clutch (Clutch kit). since i blew up my last motor i had to install a new motor it came with a upgraded head with Tomei Solid Lifters. And im thinking since the person before me that Fast 1 motorsports bought the motor from installed the Solid Lifters they would of had to install different cams and etc.
