I got some questions for you guys with blowers.
How much boost you guys are running? I'm running 10psi on my 3.8L S/C in my Monte Carlo Intimidator SS. 7.5 was stock. It's a stock M90, not the M112. I have no intercooler, but extras from ZZPerformance. You guys should be about 10-13psi? Anyone up to 16-17psi yet?
Are the intercoolers air to air or air to water like the Cobalts? Air to air like the GXP, right?
Has anyone put a GM cam kit in, or different rockers?
https://www.zzperformance.com/cobalt_ion/products1.php?id=862&catid=143Are you porting the blowers and intakes? (this link shows the M90 ported)

https://www.zzperformance.com/cobalt_ion/products1.php?id=920&catid=143What size injectors are you using now? Anyone using 60#? 72# or 79#??? I'm using stock 34# and running out of steam.
http://www.zzperformance.com/cobalt_ion/products.php?id=174What size S/C pulleys, stock 3.35, 3.1 or 3.0, or smaller? 2.8, 2.7, 2.6 or even the 2.5? I got a 3.4, with 3.8 stock, but again, no intercooler. Guys with I/C's on L67's are running 2.8's on their M90's, I drove one with a 3.0 on a ported M112.
Modular pulleys?
https://www.zzperformance.com/cobalt_ion/products1.php?id=446&catid=142Are you using fuel pump voltage boosters?
Colder spark plugs? Copper? Iridiums? What?
How are you detecting and controlling knock retard?
Will the LS4 75mm TB bolt on as it does to the LSJ's, with minor modifications?
https://www.zzperformance.com/cobalt_ion/products1.php?id=999&catid=174Is there plans for adding a turbo to the S/C, as ZZPerformance has done on their Cobalt? Every time I stop in there, they try to talk me into adding a turbo kit to my L67.
https://www.zzperformance.com/cobalt_ion/products1.php?id=871&catid=143They have dyno'd 440whp on pump gas. These guys have the world record holder 3.8L FWD (900+bhp, 800whp), at 8.66 and 159 in the 1/4!
