My engine is at the shop and being built this week. I am doing a complete 383 stroker long block build up to prepare my ls1 for F/I in the future. I was just wondering what kind of horsepower i am going to make with 9:1 compression without the turbo.
I am using callie crank, callie h beam, mahle piston, double roller timing chain, ls6 oil pump, Patriot LS6 Stage III heads 2.08 intake 1.60 exhaust, thunder racing blowr cam 219/230, 117 LSA, 160 degree thermostat, 36 pound injectors, harland sharp rocker, completely new valvetrain, powerforce plus harmonic dampner, ported MAF sensor, new plugs and wires,borla exhaust, stock intake and exhaust manifold for now?
Does anyone have any idea what kind of power i will be putting down at the wheels N/A????

 

Isn't a 2.08 intake valve kinda big for a stock 3.90 bore? Might want to ask about that as well. I've always read, been told it shrouds the valve. Hopefully someone more knowledgeable will chime in.

As far as power, don't have a clue...

 

Its not a stock bore. Its been bored and stroked 3.905 bore 4 inch stroke

 

Needs more cam/intake and DCR to make HAPPY N/A power imo. Looks good for the FI setup though.

 

i know its not a good setup for N/A but im not gonna have enough money for the turbo until next year so is my car gonna be any faster than stock right now? How much power can i expect right now until i got F/I?

 

390-400 rwhp thru an m6

 

built engine with stock intake and exhaust will rob a **** ton of power since you asked for N/A numbers. i would say 385hp

 

That 385HP sounds about right for the way the motor is presently set up.

BTW your block was not bored....it was honed to 3.905....and that equates to an increase of "one" cubic inch....the four inch stroke makes it a 382.The valve size you are using is better suited for a 4.00 bore.

 

I dont know, but isnt that cam he chose better for a supercharger and not a turbo? I have been seeing turbo cams and they are more along the lines of having the same intake/exhaust duration. (i.e. 220/220, 224/224)
