i stopped at 27 degree's. im sure it can take more, but the minuscule power gains aren't worth hammering the bearings over.

pump gas sucks

 

was ur dyno on e85 also?

 

25/75{e/91octane} blend. i was in the middle of tuning the timing tables for random mixes i might run across. me personally, i have zero desire to tune my own vehicle. from ethanol free to e85, i don't have to do a damn thing to it. my last car burnt me out on tuning.

 

Just noticed my dyno pull was in 4th not 3rd... Does it matter?

 

Dyno pull in 4th gear will result in VERY slightly better numbers than pulling in 3rd - 4th gear is closer to direct than 3rd so less loss through the powertrain. Like I said, VERY slight - probably 1% difference or less.

Pat made my pulls in 3rd gear as didn't like the idea of 6000+ RPM with 3.42 gears and 32" tires, which my quick calculations would equal around 150 MPH!

HTH!
