Most people relate supercharger output to that of a roots style (like a magnuson or a Roush). The supercharger we use is a centrifugal style (similar to a procharger). With a roots style, you tend to make high levels of boost down low, which make for great low-end torque. However, they usually run out of air at higher RPM's and fall off. With the centrifugal style, you don't usually make boost till about 2500 rpm (depends on engine rpm and max boost) so they usually make better power up top. Now if you are concerned about over-loading the driveline at low rpm (15-2200), I don't see any added stress from this perticular supercharger. We have a system on a 2006 H3 development vehicle that we have been driving around. It has pretty much only been driven on the road, so I can't give any feedback to how it does in the crazy situations some of you are looking to put one through
. I have a dyno sheet on it, but it didn't print very clear so it doesn't show up when I try to scan it. Here is a summary:
Max Power - 242hp @ 5800 rpm
Max torque - 226 ft-lbs from about 3200-5000 rpm
Max boost - 7.78
These numbers are pretty conservative for a stock engine. Of course you can push the boost for more power, but at some point I would worry about the pistons. I'm going to contact some of my guys at GM, as I know they have pushed this engine with both turbos and superchargers until they broke. I'm curious as to at what level they broke, and where they broke (pretty sure it would be the pistons). As I get info I will pass it along.
