I've recently converted my 914-6 to a 2.4S spec engine with PMO 40 carbs.
The engine/heads are standard S spec but with 2.2S pistons giving about 9.3:1 compression rather and the std 8.5:1. Can any one recommend a specific cam profile/supplier that is optimised for use on carbs with an S spec engine ? If the std S cams from an MFI engine are considered to the the best for this application then I would be happy to hear your experiences. I'm looking for a fast road cam to give me similar performance to the std S cams on MFI. The car is used on the road as well as for competition, so I need something smoothy and tractible at low RPM. Regards Andrew |
