To Turbo or to Supercharge, that is the question.

Dont you think a supercharger would be a nice addition to your rig?

On your technical specs it mentions a flat spot on the unit must be installed down and within +or- 15 deg from horizontal. I assume this is for oil flow and cooling.
When offroading it is possible that the vehicle will be more than 15 degrees off horizontal. What is the potential for supercharger failure?
How long will it last in this condition?
If it does fail would it be considered an out of warenty failure?

Great questions.....

c'mon no one actually gets their H3 more than 15 degrees from horizontal! Hummer uses a special oil pickup on the I-5 as a poser mod, not one that's actually needed. I just measured and I only get 3-4 degrees going over curbs - that's the worst offroading I'd ever want to subject my H3 to in real-life situations.

How much power you going to get on the 3.(and how many front differentials will you have to replace. )
The stang will kick a$$ with a supercharger

Bebe how come there are no pics or videos of the stang.
Lets see some holeshots ,flatspins and donuts


Ill post some of the 442 soon.

What about that 'stang? Details/pics maybe.

Spends most of her time in the garage. The H3 has 48K, the pony 8K, bought them within about 2 weeks of eachother.

I'll see if I can find some pics.


Edit: Found one

Her upgrades so far, Magnaflow exhaust, superchip w/CAI (brought the HP to 350), lowered, and some other cosmetic stuff.

The 15 degrees is the static mounting requirement. We posed the question to them a while back when we started working on a Jeep kit. They told us they see no issue with short term driving at steep angles. I'm sure once the pump is primed there won't be any issues. Now if the vehicle was parked at a 60% grade for hours then started up and driven on that grade I could see some issues. But I would be concerned with the engine having a problem with that also.

Since we are in the process of developing a Jeep kit, I am going to try and push to do some gradability testing of the Rotrex unit. We have specs for many of the OEM's, so we could use that as a start. I'm sure as we get into more and more off-road vehicles this question will come up.

As for power potential of the '07 H3, I'm not sure yet. We usually see over 50% increase in power. The base power was 175, so I would hope for at least 275....at the wheels.

Hey Bebe, have you seen the glass back roof for the new stangs? We have one in a development vehicle. They are made by classic design concepts. They are SWEET! Heres the link....http://www.glassbackroof.com/
