I know many people dont like these threads but if you've got some time to kill and dont mind lending me some of your infinite knowledge, maybe you could give me a little input. Well, I'm going to get my car dynoed and was wondering what I should expect. Now before I go into my mods in detail, I just want to let you all know that this car has been built on a MAJOR budget so dont flame me on all the stupid moves I made, I know there stupid so you dont have to tell me. Also, just wanted to say that the car dynoed 369 rwhp on the stock motor. So here it goes

383 Stroker Motor
Approx. 9.6:1 (I know to high)
Stock LT1 Heads port matched and ported LT1 intake
LT4 Hotcam Kit
52mm TB
Stock Exhaust Manifolds
TH400 with a converter that might has some slipping problems
3.23 gears (i needed some driveability)
Vortech S-Trim w/ about 10psi (i had 8psi stock and have cometic gaskets now so I'm not to worried about it)
Water/Alky Injection
PCMforLess tune
42lb Injectors w/ FMU

So basically since the 369rwhp, i stroked the motor and cammed it and upped the boost - so what should i expect? if theres any other info that i can give to better estimate let me know and thanks to anyone, if anyone does, who gives up some of their time.

 

On my old turbo setup, I added heads, cam, larger turbo and upped the boost from 7 psi to 16, and I picked up 175 Hp on the dyno...

I know it's not a great comparison, but... I'd say addin 2 psi, cam and some cubes gotta be good for 50+ hp or so. I wouldn't be too optimistic if you aren't changing the tune on the dyno though, it could be way off which will affect the numbers.

Thanks that helps but i did get a new tune with the new motor.

 

Is there a reason you're still running stock manifolds? I bet you'd notice a significant increase switching to any header w/ the best being one of the longtube variety.

Good luck.
