An 85 911 with 62,000 miles just became available in my area. It has a Paxton Supercharger which was installed by "a local Porsche mechanic" the installation looks neat and clean. But I can not contact the mechanic. Has anyone had any experience with this? Should I run to it for run from it?

I happen to like Paxton blowers, but I just don't know if I would want one on a 911.

I'd concur,.....

I like Paxton blowers too, but not on an air-cooled engine and I wouldn't buy any 911 that had one.

Steve, a question for you, if I may.

I've supercharged previously naturally-aspirated cars before, and one positive point of a super vs turbo charger is the intake air temps (boost dependent, of course). If an air-cooled engine is capable of dealing with the inherent temp increases with an exhaust-driven charger vs. a belt-driven charger, why the blanket statement, or is it more along the lines of assuming it's because it won't have a lowered compression ratio?

Folks do have to understand that if you're approaching 1 bar supercharged, the intake temps are still significantly higher than ambient air... sometimes to the tune of +50 to 100 degrees F I've observed under constant use at the track. I ran a non-cooled pent-roof headed water-cooled V6 at 9.0:1 & 1 bar of boost, & the same engine type w/ 9.8:1 & .7 bar without detonation. Obviously (to me anyway) the 911's w/ single plugs are going to have a big problem with this setup. But even with low boost levels (say, 6psi?)

Thanks Steve.
