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. |

Altitude and compression are important variables for timing
I change timing depending on the altitude of the track |

QUOTE(brant @ Dec 10 2020, 11:10 AM)  Altitude and compression are important variables for timing I change timing depending on the altitude of the track For all intents and purposes it will live most of it's life at sea level. There is one track that is at 2300' so I'd add or subtract a few degrees? The driveline was originally built and jetted for much higher altitude, so i've been wrangling with that to. I installed an AFR gauge so that has gotten easier. Modern tech, gotta love it.. |
