New best
Went to a track rental. As usual I couldn't get the stuff that I wanted to do done like leaning it out (was 10.4afr), lashing valves, plugs, and reset timing. Anyway, this was leaving off 4.5-5psi with 5° of timing pulled and ramping to 14psi. I made a mistake and had my timing 4° down from where I wanted it. I think it would have ran a 5.6x or better leaner with a couple degrees more timing. Idk. Not hateful for a little over 3,800lbs.

Thanks! I spent some time with the suspension and cage this year. Got tired of spinning. It's starting to come around.

Thanks! I don't think I've seen you post in a while. Is everything still good with you and your car?

Hi Curtis did it run 9.80 in the quarter ? Did you let off because it said 98 mph . Slowe;6296845]Went to a track rental.

Yeah, let out at the 1/8. Would've gone 8.9x-9.0x in the 1/4. Last edited by Curtis Slowe; 12-17-2021 at 09:01 PM. |
