I've got a P600B with twin intercoolers, paxton fuel pump, vortech t rex pump, crane ignition (brand new from Vortech kit) if your interested. The blower has a 12-rib setup for approx. 11-12 psi on a 355, I made 525 rwhp with it. The blower only has around 10-20 K miles on it and the intercoolers even less. I took it off cause the blower was too loud for me and made my car stand out too much. If you like blower noise, this is the one to get. There was a guy with a P1sc on a Vette around the corner from me, you could hardly hear that one compared the the P600B. Shoot me an email if you or anyone else is interested. I have pics.

Thanks,
Ed
