Blower Cam I am looking to do a cam to "improve" on the efficiency of my Procharger. I have a D1SC on a LS1. I am looking at running the cam with stock heads for now, but will likely go to some STG 2 LS6's in a bit. I know that a lopey cam isn't always the best for a blown application, but I kinda still want that "Muscle" sound to it. I was thinking about doing a 02 ZO6 cam, but I would like something a little more. Let me know what you think. I know there are sponsors selling "blower" cams, but I want to know what the masses think.
It's for the GTO in my sig.
Thanks in advance

I had a non-blower cam in my car when I added the procharger. Cam is a 228/234 .588/.598 (Comp XER libes) on a 112+2 LSA.
It did right at 400/375 to the wheels (Just cam and boltons) before the blower and 546/504 with the P1SC at somewhere around 9psi. The HP was in the 540's from 5700 - 6600 rpm so I'm sure it could have made more if we weren't pulling timing and dumping fuel to try and make it last a little longer.
You can see the dyno graph in my other thread, and it made pretty decent low end torque for the mods. At 2900 rpm it is at 400 pound feet, at 3500 rpm it's doing 442 pound feet.

This is on stock heads, stock bottom end (Just pushrods and valvesprings changed to support the cam.)
The cam may not be ideal for the boost, but it did alright.

We put our blower camshaft in this GTO last year, along with an ATI ProCharger D-1SC. http://www.exoticperformanceplus.com...Car.php?car=11
We had it on display at the ProCharger booth at the Super Chevy Show at ORP in Indy. Every time we fired this car up it would draw a crowd around it due to the lopey sound of our camshaft. We're now in the middle of installing a Moser M9 rear in it. Bob

I went with the LG GX5B cam. I believe the specs are 228/234 .588/.598 115 lsa. Its a tad smaller than Exotics cam, but man did it pick up the power and it performed great at the track.
Can't go wrong with either.

Bob, every project car you guys do comes out looking clean. I'm trying to find comparisons of other procharged cars running a stock cube (346) on 8 to 10 lbs of boost so I can draw some informed comparisons of various setups. You wouldn't happen to have any examples of this with some numbers would you?

The GTO's are heavier and typically don't 60 ft as well. Heath is on the verge of getting into the 10's with a six speed. Bob
