450rwhp? They are claiming 630 at the crank! In a L99 with the 18-20% drivetrain loss your looking at 515-505rwhp (with longtube headers, CAI and tune). That's 500+ RWHP that is ALOT more reliable than a blower car. Personally I LOVE the procharger but due to $ and the fact that these motors were not built for boost I'm building all motor and maybe a 100 shot. There are guys on here running 7+ psi that have had great luck but my luck is not so great so I'll play the safe route. As for drivability... With a good tune and in my case a 3200 stall converter with trans cooler it'll be just fine. As for usable power... With that kinda power from a sub 25 punch in an auto it'll just break lose anyway and on the highway/interstate downshift from say 65mph in either manual or auto will yield a 4500rpm start and wont take long to reach the 6k mark and keep you in the big power range. Other than that you'll be fine at the track... Lots of all motor + spray cars running hard with blower cars.
