Weber jetting needed
 

I'm building a set of 42mm IDAs for a 3.2 with early 930 cams. The car will be used for DE events but is not a dedicated track car. I'm guessing that peak HP will occur at 6000 RPM so a 36mm venturi size would probably be best. Since the engine is a lower RPM engine I'm guessing F26 emulsion tubes would be better as opposed to F3's. Any real experience in jetting this engine would be appreciated.

Cheers,

Paul
