02 C5 with Magnuson - Before / After With LG Motorsports G5X-B cam 
Before was done with Dual filter intake, Corsa Cat Back, 1 5/8 Shorty headers and Magnuson intercooled blower with stock pulley
After is all the above plus QTP long tubes, LG Motorsports G5X-B cam, Comp 921s, and cats removed!
Car was kinda a slouch before the cam as it was torqey but missing that extra power... the cam fixed that problem making it pull STRONG all the way to 7000 rpm, while maintaining stock drivability, a good lope and INCREDIBLE pull throughout the rev range! this car is a FIERCE freeway car since it has stock gears and has top end like ive never felt from a vette around here before for having stock heads and bottom end! I HIGHLY recommend the cam to ANYONE looking for more power with the blower but do not want to sacrifice drivability! I think the car might have had a little more with an agressive tune but we tuned it for 91 octane as that is all we have here, and it still had stock run flats on heavy wheels. I believe we are going to crack 500 rwhp easy with the electric water pump and normal street tires when he comes back soon!
Enjoy!

Far as the cam specs, I think Lou is keeping them secret!

personally i'd like the power shifted down more toward the midrange, wonder if he change the duration to do that. The cam doesn't even wake up till 5-5500 rpm.

I thought the magnuson's get to boost quicker than centrifugals like mine and that weren't as dependent on rpm.
I'm sure the AFR's would give this car that nice midrange power that would be very complimentary to the high rpm power it already has.

CHRISPY,
