new cams - what to change
Hi,
I'm planing to install Piper DUR1892 cams.
The engine runs with a Cosworth Roller Barrel and Omex600 since one year, without any problems.
Everything else is standard.
My question is, what should be changed when using other/those camshafts?
More fuel, of course - but what about the ignition? Completely increase?
