I have more or less always used this Dynojet. I used the dyno dynamics just the one time (should have staid with the one I used for 6 years). Now he has sold the shop and dyno (dyno dynamics). So I can't put it on that one again.


I'll get the pump rebuilt and have a couple other ideas. Talking to another guy on e85, he is running it a lot leaner than I am on E85 and going 128 in the 1/8. I noticed every time I leaned it out, I picked up power. Never saw the breaking point nor detonation, just started getting nervous going leaner than .78 lambda. If I do go as lean as he is, based on power increase per .01 lambda, I might just make another 30rwhp before the pump, rockers and headers.

 

I've seen people go all the way up to .86 lambda to find peak power. But most I've noticed had been around .80 - .82. I wish I had a dyno to play with these things.
