Hi all
I'm new to the site and wonder whether someone can advise me on the ideal setup. I miss my Hummer H2 and decided to buy a new H2 SUT. I've driven the 2008 model and actually it's a slow beast. Not comparable to my previous H2 who had a whipple charger on it. The reason for this post is to gather information for the best set-up for what I'm using the car.
I like the Hummer as its a great car for pulling heavy load and at the same time an incredible comfortable drive for the longer distances ie trips to Germany & France. Considering this I'm looking for the quiet ride and enjoy the driving = not the loud thing to get noticed (an H2 is noticed over here)
At the same time I like some performance and like the kick off and see how people are surprised that such a big beast pulls off like that. The max I got out of the previous one was about 210km/h +- 130mph.
And .... fuel is expensive over here so want to transform it to LPG.

I think for the purpose I want it the best choises are.
1) The Corsa Touring exhaust system as that one is not too loud.
2) Some nice 28" wheels
3) The Whipple supercharger. (They replied me they'll be offering it for the 6.2L engine soon with an intercooled Kit).
Your ideas - information is welcome.

 

Look at the TVS from magnacharger also.

 

Big wheels hinder performance. I'd be interested to see the power increase over S/C with gasoline that LPG's higher octane and a retune will give.

 

TVS doesn't have a charger for the 6.2L engine. The only ones I found so far for the 6.2L hummer is Big 3 performance & Pro Charger. For what I'm using it I think a screw would be better

I know big wheels aren't good performance but the for the looks. Regarding LPG with the S/C I haven't got a clue. don't know people over here to tune the car you see.

 

I can't even imagine how much 28's would kill the performance, my guess is the blower will negate the heavy **** wheels.

I have 24's on my 2008 Silverado, and they weigh right at 100lbs per corner...

 

on my previous H2 I had 24' and they weren't bad. It's just and idea to put on 28's for the looks. The bigger problem is finding the better charger for the new one.

 

I would say use the TVS1900 as soon as they get the calibration finished.

 

There is a 6.2 Hummer in the shop as we speak.....You can have your hummer system in 15 days from Monday.

 

leftcoast32 : what do you mean with calibration?

blownchevy : pls send me specs about the H2.

 

By far a TVS is what you're going to want to do. By calibration he means the tuning. Magnacharger actually builds a system with good pcm tuning unlike most other boosted manufacturers.
