High Compression Boosted Build
Good afternoon gentlemen,
My current build:
2001 Z06
LS6
D1SC A&A Kit
RC 750CC Injectors
Dual In Tank Welbro Pumps
FAST 92 Intake
LS6 TB
LG Headers
Corsa Exhaust
Monster Stage 3 clutch
currently on 7lbs, made 558rwhp on a Mustang dyno (Drivers race against a heads, cam, intake, exhaust C6Z)
With this set up, it feels like there isnt much power/torque down low.
I have been thinking about installing a 11.5:1 LS2 based 402, increasing the boost to 10lbs, methanol injection and calling it a day.
Would it be advisable to run 10lbs produced by a D1SC to 11.5:1 comp?
Thanks in advance!

What size blower and crank pulley are you using? Save your money. You are barely pushing a D1SC at 7 psi. Why not increase the boost with a smaller diameter pulley?
You mentioned there isn't much power down low. What rpm range are you referring to?

You are really selling your setup short........... refine
10lbs +meth on your current setup should make a noticeable increase
with smaller pulley you will also increase tq across the rpm range (including lower rpm)
your LS6 10.5:1 static compression - is well suited for 10lbs with meth

For extra credit, post up vids of you walking the C6Z. Bonus points if you include video of your C5Z decimating a C7Z.

See changes in bold above.
As a trusted advisor, I would have to recommend that you run 10lbs on your current LS6. Please erase any thoughts pertaining to increasing the compression ratio.

I drive all over Michigan, I want to avoid searching for fuel.
