Has anybody used this supercharger?

I think you can do it, I just think the quality of the tuning and parts in the kits that have been available have been sub-par. On the 996 side VF Engineering has sold over 500 of their supercharger kits that run a mild 6 psi. People are tickled with them and they seem very reliable. But VF does it right. They supply larger fuel injectors and have the ECU reflashed with a custom GIAC tune. I think that's the real key here is that they had an industry pro like GIAC tune the thing.

TPC used a 7th injector and a Uni-chip piggy back ECU for their 996 supercharger kit and now they've followed suit and switched to using larger fuel injectors and a custom ECU reflash like VF.

Based on what I've read the IA and TPC installs were crap and yes tuning was an issue too. Just look up Gary in BR's dyno chart comparing his IA setup to his TurboWerx setup. The IA supercharger was making almost nothing over stock!!!

It looks like TurboWerx might have things right with the current Boxster S turbo kit they sell - low pressure (like 5.5 to 6 psi) turbo with larger injectors and a custom ECU reflash. If their tuning is good (and that's a big IF) that should be good for a reliable 100 HP, which is what they claim. If the 996 and VF Engineering guys can do it reliably with the 3.4 and 3.6L engines, then we should be able to do the same, if not more, with the 3.2L which is theoretically stronger!

IA is no longer in business....

It is worth noting, that on the M96 motors, it's relatively simple to update the sleeves (LN), very easy to update the rods (R&R, Pauter, etc), pistons (JE), but not the crank. These motors unfortunately don't run a forged crank, and finding someone to make a forged crank for these motors would be cost prohibitive by itself.

As to how long it takes a turbo motor to blow up, a significant portion of that depends on how well it's tuned.

I will say, however, that I think a proper turbo kit, done within the realm of sanity, is possible on these cars, and that no one to date has done it right.
