02 About to Supercharge

Are you kidding.....that's barely broken in. The 4.6L in my Cougar had 235,000km on the clock before I tore it down to beef up the internals. The cylinder walls still had the original cross hatched pattern in them and the bearing were barely worn.

I wouldn’t worry in the slightest about strapping a blower to an engine with so little mileage on it.
 
if your car has been well maintained and you have a safe tune, you won't have any problems. There are plenty of guys pushing 200,000 miles on supercharged motors. It wouldn't hurt to do a compression test before you make the investment.

:nice: Wise advise.

I remember seeing pictures of that engine on here a while back it seems.

I'd say go for a centrifugal to keep the stock drivability on the lower end of the powerband.

ATI Procharger: P1SC, D1SC
Vortec: V-1 S-Trim, V-2 SQ-Trim

All of the positive displacement blowers for these cars have bypass valves, so part throttle drivablity is not effected.

Positive displacement blowers drive stock as a rock until you start putting your foot in it. The only issue after that is the smile that all of that low end grunt puts on your face.

As a matter of fact, drivability is often far better with a positive displacement set-up. Most systems will pull hard all of the way up to redline and you don't have to step up the gearing to pick up the low-end like you do with a centrifugal.

Regardless, it's been shown that either system work well with a 4.6L, whether it be street or the track. You've just got to decide where you want the majority of the power to hit. Stock grunt down low, with power in the mid/high ranges with a centrifugal? Or brute torque in the low/mid ranges, tapering off up top with a positive displacement system?
