Hi all.
I have a query in regarding how much advance is apropriate. I myself cannot run more than about 27 degrees total advance. At the moment I am running 10 degrees initial and about 16 degrees in the curve and seems very good on 98 octane fuel. Any more initial and the engine will ping when hot. The best allrounder is 10 degrees initial. Is this a problem? Do I need to reach a magic figure of 30 degreees and over for optimum performance? Or is this ok. Its been set up to have 10.1:1 comp with a Comp cams (xe274 230/236 @0.050) with stock heads. From my understanding I think I am not bleeding enough compression with this cam and compression is too high.
Can anyone give some advice?
Regards
