Thanks ! Really no clue. Last time I weighed it, it was 3715 with me at Norwalk , but I have taken quite a big of a weight out of it . If I had to take a guess I would say 3300lb with me maybe less. When I go to Milan or 131 I will have to scale it. I'm quite interested to see what it's at.

Went to ubly drag way today instead of shitty lapeer.
Much nicer facility all paved pits, well maintained, track prep is good . It's up in the middle of the thumb in michigan.
Made 3 fueling corrections to it all day, added about 3 tenths of a percent to the power enrichment table that's rpm based, which isn't much but im trying to take baby steps with it. I've managed to whack almost two and a half tenths off it. Went 10.73 at 125 and some change .
This was on motor.
Car is still a bit lean going down the track. Also at the hit the car goes way way rich . That's kind of why it's not sixty footing hard.dum
Anyways a successful day. Every change that I made it picked up et.
Density altitude was 2950!dum
Long live the opti bitches

Thanks
It's a br7ef gapped at .032 . Stock ignition
Static is at 12.8:1 , cold cranking psi is at 240 to 250
The plug recommendation is what I got from reading lots and lots on the fuel section on yellowbullet. Mark sullen recommends a ngk heat range 7 for just about everything on e85, but the mixture has to be tuned accordingly (fat)

Ya its good stuff for the guy that's running decent compression and don't want to shell out money for race gas.
Try to target Between 11.7 and 12.0 on the gas scale with a -7 plug.

Figured I'd update went to milan last night .
Was supposed to be a test and tune but ended up being a cluster with grudge event going on. First pass went 10.66 at 125.2 . Then brought it up 200 rpm more on the converter and went 10.58 at 125.7. Got to race my buddy Jims lt1 30th . He got his best of 10.28 at 131 with a 150 shot with some issues out of the hole .

Thanks Travis . Would like to see what it does on the bottle. I'm not going out next weekend . Just going to the ltx shootout 2 weekends from now. Gonna run it on motor in the modna class and I have a 100 shot on it to run the modified power adder class. It ain't gonna be enough to win that but I'm not gonna throw big jets in it right off the bat.

Be sure to update the thread when you go to the shootout. I will send you a p.m. or post on here when I get it switched over. Car is 11.5:1 so I hope to pick up a little power.

Do it. Add some more torque to the 383. Just what it needs lol. I just watched one of your youtube videos, if you are still running the stock MAF I would put the new Delphi unit on there. It is bigger in diameter and not tapered like the stock unit. Plugs right in and Solomon told me it shouldn't need retuned when I bought it. It's a true 85mm vs the stock 78mm. At your power level I bet there is a gain.
