So what... still isn't anything impressive. Especially considering it is a 3.0L blower. There are 2.6s and even 2.3s making that power with the same psi and good tuning. Hell, I made over 500 to the wheels with a 9.5psi pulley on my 2.3l. I do like how they can't get a consistant psi out of the damn thing so now they rate the pulley for a range...i.e 7-9.5psi.
Bottom line.. a 3L blower at 9.5psi should make a hell of a lot more power than that. Think i'm wrong? Just ask any of the 2.8L KB people how much they are making with 9-10psi. I promise ya it's more than 450. Shit, for that matter, pretty much any blower out there is making at least 450 with 10psi.
As for your post.. at least put a LITTLE bit of effort in to it other than just a link to Brads site...geesh.
