The Head Unit looks like a Vortech (Will have Oil Lines)or Powerdyne (Internal Belt or the new gear driven with self contained oil), Your Boost is more than likely 6-8 psi. Did it come with a blow-off valve? Most of those type superchargers (centrifuge) use about 13% of your HP.
Note that Centrifuge types are not that linear, as your revs increase so will boost. Roots-type are little more linear.

I would get a boost gauge and A/R ratio gauge or a DashHawk tokeep an eye on rich /lean conditions. Did you get replacement injectors?

Having the Alpha come outstymies the aftermarket to make power-addersfor a 5 cylinder.

As far as putting a V8 in, a Crate motor almost cost as much, then you have to get wiring harness, PCM, motor mounts, exhaust, change shocks and springs, front suspension parts.So I don't know were you get off saying it's cheaper, if you want to do it RIGHT.

I see STS has a setup coming out, thats a good company, when I was in the Dodge arena I knew a few guys had them on there Hemi's and were getting tremendous performance with little boost.

 

Mountainbiker,

I have a Wheel to Wheel Rotrex supercharger on my 07 H3. It's been on there for about 7 months, and over 10,000 miles. So far it works flawlessly and the gas mileage isn't bad either. It is headed over to Roush this month for certification testing so it is 50 state legal. I can get you some additional information if you would like. W2W is now shipping '07 kits for the public.

 

is it bad for engine?
