Blower and LQ9 combo?

**Badass99SS** · 10-06-2007, 07:02 PM

So looking for heads that will compliment a procharger set-up. I definately want to go with a patriot product, was looking in to the LS6 stage II heads. I gave Gunnar a call at Patriot and he recomended LQ9's, does any body run these heads with a blower set-up and if you do what kind of performance are you seeing? The guys at Patriot are really great, just would like to hear some feedback from somebody who runs this set-up......Thanks for any info

If I am not mistaken, the LQ9 heads have a larger combustion chamber which lowers the compression ratio. Which in turn allows you to safely run a little more boost.
They flow pretty good from Patriot. Gunnar is top notch, and knows his stuff. Very helpful and I can't see him steering a customer in the wrong direction.

He did me VERY well on my heads for my 402 LSx.

Ya the combustion chambers are larger, it will take the comp down around 9.3:1-9.5:1 thats why he recomended them. What heads do you run?

I have a N/A build...running Patriot Stage III LS6 heads.

what kind of power will you see from a procharged LQ9? that could be pretty nasty...

Well I hope to see around 400-450hp N/A, then add the procharger(30-40%). So when all is said and done I would be happy with 520-560hp.

you know it might be cheaper to just stroke an LQ9 and build it up. Mr. Luos is pushin that n/a

Ya it probably would, but my goal for this build is for the car to retain its original motor. I just built a 69 Chevelle with a bored and stroked 454 to a 496the car was pushing 500-550hp but the cam in it was so damn big.I want to build this motor to have good power and diecent fuel economy, when I really want to haul ass I will get into some boost. But the most important thing to me is to keep this original motor in the car, I have a clone SS Chevelle but I have a real SS Camaro.Learning from peoples mistakes in the 60's-early 70's I want to keep this car intact.
