Hey!
I had my 2006 H2 installed with Supercharger (2.9" pulley), custom tune, little tranny upgrade, dual fans, 160 t-stat, Dynatech headers with WRC cats and exhaust.
I shortly tested it the other day and it said 5.7s 0-62 mph, I really sounds too good to be true and I plan to do some more runs, but it is really is a rocket (and loud). Actually there is way more power than I have courage to push it. I've heard that rear end won't be able to handle it all, so I really don't want to push it too far.
I think SC, tune and the exhaust did the job...
btw, I have 37" tires, so there is more meat the engine must move.
If I just have the time, I'll go out and do a vid for you.
This is the face I'm getting people driving Volvo T5 when they see my tail light off the lights
