WK1 General Performance DiscussionIf you are planning on modifying your Jeep Grand Cherokee SRT8 with a performance enhancing modification, this is the section to post about it.
I have been wondering if we have any numbers from guys that just have a supercharger and no other major mods like headers,exhaust,cam, built transmission, ect. Just want to know what the best times are for supercharger modifications only?
Prochargers sound sweet, Magnuson's look amazing, and Vortech's have great reputations...but which one runs the best without any other major modifications?
I just ran my personal best with a Magnuson 6lb, MTCM, and Bwoody CAI...

I believe a couple guys have run high 10's with a Vortech and a few bolt-ons.

I think tony was pretty stock except his SC and went 11.1 also before Jake did his cam he was in the low 11's 11.2-11.4 I think. Not sure exactly when he put his cam in.
So many variables involved with this question however, there are guys that have maggies and vortechs that run super slow too, but then there are others that run super fast, as far as procharger guys go, not very many have made it to the track yet so there's no real world data to work off of until more guys hit the track. I've only seen one guy hit the track and that was 10GCSRT8, Brian, who ran 11.4s with his setup on $hitty tires to boot spinning through first gear, still had a pretty decent 60' time.

The average is mid-low 12's with a blower only on a stock Jeep. Reason being is that once you start getting to 8 psi +, you start to need a built tranny......and then the mod bug bites.
Well if I get my a$$ to the track I will tell you what a stock truck with only a SC will yield. Procharger D1 is all I have plus a Cat-back. Everything else Stock.

We have a guy in our group and all i think he has is cai, vortect and i think he still has stock exhaust and at our 1/4 mile track which is 14 ft uphill he went 7.26 1/8 11.64 1/4.

Really what I am looking for is a close as possible comparison for the superchargers out there. Magnuson, Vortech, Procharger, KB. It is not a real comparo if there are headers, cam, exhaust...because that doesn't make for a apples to apples comparo. I cannot wait to see what the prochargers are doing on the track. Stock with superchargers lets see those times!!!
The air here sucks, but for comparo, I ran 12.3 with my maggie. I ran 13.6 before, on a good tune.
