Supercharged Nissan 370Z in Cannonball One Lap of America 2009?

You can safely assume that any supercharger dyno we perform here is done using a car that has been equipped with an exhaust system. Supercharger's definitely see benefits of opening up the exhaust similar to a turbo however you don't want to use too big of a pipe. On a turbo car you generally see exhaust piping around 3" diameter. This is a little too big on a supercharged application.

For example, we do not recommend running headers on our current supercharger configuration because the decreased backpressure causes the supercharger to drop one pound of boost.

Good, cause I cant pass emissions here with those anyway more than likely haha.

Im VERY much looking forward to seeing a completed kit, and price...

but dropping boost doesn't necessarily mean you're losing power.........going from a stock header to a race header in my supercharged RSX did the exact same thing in dropping boost, but the blower/engine were more efficient with the improved breathing and I gained power........of course I'm sure an I4 and V6 work on diffrent basis of mechanics so everything I just said might be worthless in this case.

I do agree about going to big on the exhaust side, no point in going with an exhaust that's bigger than your header flange imo, b/c the "choke up" or hold up point is the collection of the header(lets suppose 2.5") so going bigger(3") won't reallly "free up" anything...........of course 3" downpipes to 3" exhaust are a diffrent story......
