I plan on supercharging my 4.3 Vortec. Has anyone done it? And if so where did you get it from and what are the performance numbers?

 

Seriously? You obviously haven't searched "supercharger" or anything in here lol.

So far with a stock cam & marine intake I got 192 or something at the wheels. Stock is around 152 at the wheels. When I get a couple issues corrected & it dyno'd for the cam I'll hope for 225 or so plus bigger gains in torque with the Lunati torque cam I have.
"What to call this thread, sofaking cool..." is mine. ZR2Dan has a build thread & he has the same Wynjammer I have but with Wynjammers spyder assembly.
LOTS to read in there, grab a few bevvies!
