Wanting to get some opinions on which supercharger to purchase for my Sierra Denali build 6.2L (L92). The truck currently has a Texas Speed VVT camshaft package, LS3 ported heads, 1 7/8" long tube headers and a circle D 2800 stall. The truck will be a daily driver. My next purchase is going to be a supercharger and I can't decided between the 2.3L whipple and the Procharger. Give me some input and opinions.

Thanks

 

Depends on the feel you want. The whipple will have tremendous off idle and low-mid rpm power. The procharger will feel like a huge NA engine with power increasing with rpm and a soft bottom end.

 

Pretty much exactly as Atomic said.

Both can be deadly when spun to their max.

 

How much of a noticeable difference opinion wise is the low end power difference going to be. I mean I like the idea of the instant power off the line being that my Denali is AWD. But I also like the idea of having the power curve build throughout the rpm range...

 

Off idle will basically feel stock with a procharger, which is why most procharger guys run larger stalls to basically not spend any time there.

 

What would your money be on in a 1/4 miles showdown with both chargers running around 8-9 boost with the list of bolt ons I have on my truck listed above.

 

Probably the procharger by a fender, but the whipple will be more fun stop light to stop light.

 

What would be the characteristical differences of each setup be say driving at 55-60mph on the open highway and going to WOT for say passing someone.

 

Whipple would hit harder at first then fade some as rpm rises. Procharger would carry the power band further without fading.

 

Instant power with the Whipple. Procharger will need to build boost.

When I had my Whipple, I made 64% of my boost at 2k. Don't underestimate the Whipple on top, it will pull like a freight train.

I'm not bias or anything.
