Does anyone know the true reason why TPC's supercharger has problems?

[HB.]

Thank you for your reply, my only question about your statement is you view of the supercharger on a high compression car. I know a lot of NSX owners who have placed a positive displacement blower on their cars, and have had no problems what so ever except changing the belt every 10-15k miles but that is normal. Given these are two totally different motors, the blower mounting, and the blower used, could be as to why it works wonderfully on the NSX and not the Boxster. The NSX's supercharger from Comptech has two kits, both running higher boost, and there are plenty of oweners of these kits who have put well over 10k of daily driving and track miles on their cars.

I can see how the oiling would cause a big problem. Is this kit bolted to the bottom or the side of the engine? Also, do you know what type of fuel management was used with this kit?

Thank you for help
