Default Any guesses

Ok So I got my meth injection squared away and I'm about to go do some WOT logging and tuning with the help of our corvette forum hero BBZO6. (when he gets time). Anyway, I currently have a 3.12 pully on my YSi. The rest of the build as it would pertain to boost is 402 engine with AFR 225 heads 2.08 1.60 valves. 24x/24x cam on a 114 +4. A DP big mouth blower intake, a ported LS2 intake manifold and unported LS2 90MM throttle body. I.W. 10 ribcrank pulley and a DP direct drivd. I have an additional blower pulley. It's a 2.75. How much boost and power do you guys think I'll see with the smaller of the two pulleys? I know its not an exact science I just want to see what you guys think.

You'll make 20 psi with the 2.75 pulley.

Assuming everything else is good to go what kind of power do you think she will make?

It's got one of your cams so I know she's gonna eat.

925+

I like to stay on the conservative side.

20lbs of boost! I sure would hope you would see 900+

You built the motor to handle big power Mike, take off that 3.12 and put on the 2.75 and let that Monster out of it's cage!

If you spend the $$$ and time to tune with the 3.12, you know you are going to kick yourself in the *** later wondering what it would do with the 2.75.

Please correct me if I'm wrong!:

Default should make 900+

I'm running the same heads AFR 230 ported on my 402 smaller cam 224/228 580/588 114lsa stock ls6 intake. YSI with a 3.125 pulley makes 16-18 psi boost, car has seen 907rwhp but makes more now since BBz06 Bret re-tuned it so you should see more since I'm automatic and yours is a stick car
