Supercharger for 2.5 - 986 Forum - The Community for Porsche Boxster & Cayman Owners

If I may....The way the blower works you are correct it makes its peak boost up top. However based on the design of the C1 and the efficiency it creates positive pressure down low. Not a ton, but with some timing and fuel the change is enough to bring the lower end up over the OEM spec car.

I will need to pull the dyno sheets as I don't recall the exact amount it was. Bottom line is with proper programming and the positive pressure the unit has a gain across the board.

Since your supercharger is one of the centrifugal types, it may not develop appreciable boost at low RPM (Boost Threshold), but still uses up prodigious amounts of engine power to operate thus possibly eating up more fuel even when just doing the daily shopping.

Do you have any data in regard to this?

Thanks

What would you estimate the 0-60 is on a stock 2.5 fitted with your supercharger?

THanks for the reply. I am definitely more open-arms to this supercharger and thanks once again !

Oh boy, things are really taking off with my supercharger fund! I got $20 in donations just yesterday! I'm saving hard too, so I might just be able to get one early next year the way it's going.

You know what's amazing to me? I finally started one of the thread topics that has four pages of responses! That's a first!

Hi,

How about posting the Torque/HP Curves..?? Perhaps even Before/After? Thanks...

Happy Motoring!... Jim'99

We do not have any estimated 0-60 times, unfortunetly. I am sure as the kits sell, we will hear from customers concerning track times, etc.

I am liking those dyno results. Very cheap HP compared to an engine swap.

Hey Doc, how often does one need to change the oil in the supercharger?
