My 600hp skyline with the old head setup and 280degree cams, and CNC ported, oversized valves etc on a 2.6litre RB26 had the best idle ever! A modern ViPEC ecu helped there too.

I had the ability if I wanted to constantly changed the ignition timing at idle, then 40, then -10 etc, gave it an almost comical idle, but even with specs set to one thing, with those cams alone, and individual throttle bodies, the idle was a thing of beauty

No issue. In the USA, it was race on Sunday, win. Sell
on Monday.


Sir William knew that. he wanted an engine that not only ran well, but looked good doing it. DOHV does that!!!

Guess I was thinking more of the heady days of racing in the 50's at Le Mans and Rheims (C & D Types) and Monte Carlo (MKVII)!
