Alright so I'm trying to figure out about how much power my engine is putting out. I know I could just and get it dynoed but it's currently not in the car and I'm wondering if I should build it first before I put it in. So if anyone is running a similar setup I would love to know your power outputs. Thanks in advance.

Parts list

Sr20det notch top
Enthalpy rom tuned Ecu
Nismo 740cc injectors
Isis intake
Walbaro 255 fuel pump
Act 6 puck clutch
3inch manifold back exhaust
Hks 256 cams with vct
Vct sprocket
S15 stock turbo
And it's running on 14.5 psi of boost

what maf? probably like 250hp

mike240s · 03-26-2016, 04:03 PM

Z32 maf sensor

derass · 03-26-2016, 04:05 PM

I'd say about 300 whp.

kojiki88 · 03-26-2016, 04:50 PM

I'd say about 250ish. Mine made 267Whp and 256 torque with the enthalpy tune.
Had the same setup except I had the Toda 264 Cams and running 17PSI.

derass · 03-26-2016, 04:54 PM

That seems very low. 17 psi and cams should have been around 350 whp. I made 320 with stock cams at 15 psi.

kojiki88 · 03-26-2016, 06:18 PM

I think it was the enthalpy tune. It was tuned in Florida. I moved to New Mexico and retuned with the Nismotronic Software and made 305WHP and 296 torque.

Derass - was that with the S15 turbo?

280rwhp on a dynojet is normal around 17psi

Its really silly to force an S15 turbo past that point. You can do it, lower IAT, spray meth, more boost, squeeeeeze it for 302 or 308 but that is borrowed time. Upgrade the turbo, or turn the boost back down to 12psi~ if you want it to live long happy life.

You'll never get an accurate measurement. Every dyno reads different and too many variables per tune. [temp, dyno calibration, fuel, etc]

Its just a number and it means nothing.

Well k do appreciate all the feedback. I was just trying to figure what I'm going to be able to keep up with since people keep saying that I'll never stay with them in a race

Put sticky tyres and an LSD
laugh at anyone with more hp and less traction
