Reason I ask is I took the car out and was running 13.3 @ 104 w a nasty 2.05ish 60

Wondering if it can go 12.9x with a solid 1.8 60

Remember my times are at very high elev, DA was over 7000 all day.

We also had a VERY strong headwind. A local racer who's very consistent and wins my class often was down 2 full tenths because of the strong headwind.12.90s to 13.10 so that gives me a little more confidence.

Pyro, just the tb, cutout, and the tuning I've done to it

I think so as well AC. Gotta get a clutch n still have the AC delete to put on. Gonna try the front sway bar disconnect too.

Disconnecting the bar will really help.

I've only managed a 1.9 60' running a 12.6 at 112. That's with big cam, half *** tune, 4.10s, some bolt ons, on 20psi MT et, no kinds of deletes at damn near perfect DA. Yeah a little dissapointing... my shifting did suck a lil that day tho.

Well my car doesn't spin so it should be good there and I got compliments on my shifting all day. Just need a clutch that's not slipping.

DA should have been part of the question as well...it makes a hell of a difference.

Mine was @ ~ 3200'

Have you decided which clutch you'll be going with? and is it common for the stock clutch to give up at this power level or is yours just worn out? I was just curious........Mike
