Peter is a hell of lot better engine builder than I am. I'm really just an engine assembler.

My 2.7 with Mahle 2.7RS pistons (nominal 10.5 but not that hot), twin plug bigger ports, stock crank and rods, RSR light flywheel and pressure plate, Weber 46s, twin plug crank fire, Elgin 315 cams, and headers and stingers, made 220 at the rear wheels. I was hoping for maybe 240, which would be about 100 hp/liter. Porsche got 110/L out of the 2.8 RSRs. Torque curve was such that optimum shift RPM was 7,600. Race motor, though it idled nicely about the paddock.

I had to switch from the mag case to a sand cast one, though, after a wrist pin retainer had an issue, and during the teardown to fix that the inserted studs, green Loctited in, started backing the coils out. So I didn't get to see if the mag case was up to it in the long run.

It's on the shelf now, as the 2.8 semi-clone with Electromotive EFI/crank fire dynoed at 250 at the rear wheels. Again, I was hoping for RWHP of about 270.

Spyerx, what cam did you choose?
