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.

Awesome , I have the a very simular setup but I am on E85 , what are you running for timing and are running race fuel ? Are you running a factory block ? I am just wanting to run mid 9 ,s in the quarter with a a full weight 79 trans am with A/c and overdrive (4l80e )

I thought I had 38° in it for base timing but only had 34°. So I was pulling 11° for 27° but was actually at 23° because of the mistake. I checked timing before running and added 2° for my first pass for a 25° under boost. Got caught up in tuning the 60' and never did add more timing. Was planning on 28-29° at 14psi. Was also pulling 5° on the leave. Hope all that isn't confusing. Lol

Sorry, haven't been on here in a while. I'm using a MSD 6530 box. It allows you to pull timing where you want and at different amounts if you'd like. I drive around on normal timing and dont pull any until 3psi. It also allows me to pull timing at the leave to calm it down some. Not worried about it failing. Anything could fail at any time. Hard to say.
