I'm with Bob - quarter tank per 20 min session. Another friend who drives a stock 993 uses about the same - 1/4 tank per 20 min session.

Is this a Porsche design - all cars use the same amount of fuel

GB -- you sure you don't have a fuel leak? ...just kidding. ....Norm's car is 700-800hp with 4-4.5 mpg. Must be the CIS thing.

Joe,

I'm sure it is a CIS thing... Besides, I'm running a bit rich!

My A/F lambda ratio is 0.81 (or 11.91) @ 6,500 RPM on 3rd and 4th.
