So it's basically a bolt on 3 valve with 9-10 psi then? Coming from the Mustang world that car seems much stronger than the basic blown 3 valve that i've encountered lol! Nice kills man! 575 SAE hp equals about what rwhp...any idea?

That's 575rwhp (SAE) rather than uncorrected or STD. I make sure to list SAE, due to elevation. It makes much less uncorrected when at altitude.

Just decided it was time for a change, so I picked up a CTS-V. I hate to see it go and I'll definitely miss it. Driving it right now while the V gets some work done...almost makes me think I made a mistake...*Almost*. heh

It's a sweet car for sure! Does seem like a timebomb with stock internals though. I used to have a basic bolt on roush charged 07GT. Made somewhere around 410whp. I'll always have a spot for it!

Yea, it's about at the limit of what most consider 'safe'. It makes about 480rwhp uncorrected (remember, mile high/7500ft+ DA's), depending on weather. I have a pulley setup and tune for if it ever goes to sea level. The good thing is, it's making that 480rwhp uncorrected on a very safe tune - 17* timing and 11.5:1 AFR's.

Firehawk isnt running much boost. Horrible cam for boost + elevation. I think like 4 or 5psi? I believe his cam is the main culprit. It still makes decent power and runs strong, tho.

Also, our track times wouldn't be a good comparison..as we usually run .8 to a full second slower at our elevation.

My suggestion is to stay away from the Roush M90 blower and go for something bigger like the Roush TVS2300 or the Whipple. Tho, if I were to do it all over again, I'd probably have just sprayed it. If I were going to build the short block, then I'd definitely do the blower. It's just a lot of money to spend to be limited by the relatively weak short block, imo.
