JLT cold air kit with pulley on GT500, claim 110-140 rwhp gains ??!!
GT500 owners, I need your help on that one...
A friend in Belgium has a new GT500 and want the JLT kit for the car. He faxed me some specs and I smell BS on that one...
On their web site, they stated a gain of 110/140 horses at the wheels with: Their carbon fiber induction kit, SCT tune and a pulley package.
WTF?? If it's true, we all need to jump on that!
Also who is the best supplier out there for that particular car, without touching the blower. Same components.
A big thanks in advance

I wouldn't doubt that they got that much of an increase from that package. Hennessey Performance got a 120hp increase with a pulley upgrade, custom tuning, an intake and a stainless exhaust. Steeda also got 125 hp and 100lbs of torque from a pulley upgrade, intake and tune. Those figures are all very possible.

From personal experience we put a 2.5" pulley on and a Steeda cold air intake with an SCT tune with SLPloud mouths and nothing else. Dyno'ed at 605rwhp and then dropped to 580.
Decided to toss all that and go with Kooks all the way back andKenne Bell stage2 with a few stage 3 parts to make it street able. Werun around750-790rwhp on VP106 and 93 octaine.
I would say with a good tune he could do it.

Dan Carlson who tuned this car is generally a conservative tuner...so I bet more would be even possible...

Oh brother, not skycam again.
For the OP, when they say pulley package, they mean a smaller supercharger pulley or over drive pulleys to increase the boost.

I got that about the pulley... I wanted to make sure about the numbers though.
It's just my friend's not that good with English and didn't realize that the pulley was included in the deal.
Since I never owned a supercharged car (for now), I didn't want to assume instead of knowing for sure.
He needs the stuff by Oct 17 so I needed an answer quick, thenI can send exactly what he wants. His car will be in some magazine over there and the photo shoot is on the 17.
