Interested in opinions on timing specs. Engine is 2.0 , 9.5:1 Euro pistons, big valves, Webcam 86b, IDF 44’s , headers,92 octane clear gas. ElectraMotive crank fired with adjustable settings for Initial, 3000 rpm, and 8000retard ( mine will never see 8k).
I’ve been told a variety of advice. Need the straight scoop. Thx. |

Yeah, but "finding someone with VW experience" is a tough one. For example, I've got lots of dyno opportunities up here in CT but most are Honda or 'Mercun experience.
I'd like to find out how far we can push this envelope, but I'd prefer to not use my own engines as the guinea pig... (IMG:style_emoticons/default/wink.gif) I tune my historics racer, roughly the same specs as yours except Mallory disty, to 32* total advance at 3000 RPM. On my dead-stock-engine street car using Microsquirt, I tickle the edges with 30-33 at max-RPM full throttle to as much as 36 at mid-throttle cruise to 40 at high-RPM mid-throttle. No clue if that's good or bad. But not really applicable to your engine specs, as this is truly a dead-stock 2L engine. |
