I probably should have put my thread here instead.

• Also trapped 114 MPH on one of the runs.
• Running on 2002 era Pep Boys Futura Z-rated 245/50-16 tires.
• Spinning off the line, the 1-2, and the 2-3 shift.
• Currently have a mail-order tune. Hope to pick up a bit more with a dyno tune.

WHY IS MY CAR SO SLOW!

that's an lt1 car, right? i think you answered your own question.

i have no idea what kind of power your engine should be producing, but my lid/muffler 99 ta traps .5 less than what yours did in the 1/8 mile. there is obviously a problem somewhere. who/where tuned that setup? that that h/c combo is killer, it has to be a tuning issue.

edit: top half pick up says m6..? what clutch and gear?

Tires and practice.

Yeah it is an LT1. I am told it should be 425-445 at the wheels, and trap 117-122 (according to AI). The tune is a mail-order from MadTuning. I'd like to get it on a dyno and get it tuned that way.

Correct, M6. Spec Stage III clutch, with a stock 3.42:1 rear.

Ai is correct. I have a Vette with similiar numbers/motor as you(though I am 3200 pounds) and trap 121-122 and run low 11s on Nittos but with 390 gears.
Air quality has sucked lately so wait for some decent air before freaking out. What track did you go to?

Don't put real tires on that car till you get a rear in it

a mail order tune...? how many times did you send it back for adjustments? i can't see that motor doing anything close to its potential on a mail order tune. i'd think a dyno tune is a must for a setup like that. ba for sure and will def roll out. i think the answer to your question lies within the tune.

Dave88LX

That's reassuring. Hopefully I can at least get it into the high-teens. I'm not freaking out too much yet, maybe after a tune and it doesn't pick up, then I will freak a lil. I was at Capitol, and you're right the air was bad. 90* and high humidity.

I sent a couple datalogs to my tuner, and was told "The logs don't look too bad and code 71 can be deleted, but code 16 should not be set with a good optispark. It's quite possible that the opti may be bad."

"Not too bad", at least to me, means there is room for improvement, but what do I know.

"not too bad" could be in reference to safety, as well.

as far as full on tuning, it'd be very hard to tell without the car there and back to back runs/pulls or whatever to see how it responds to adjustments. i believe it would gain huge from a real tune. sweet setup, good luck.

Captial is not great either hence its called crapital. Wait for some good air and watch the car pick up!!
Take the car to Cecil on a Saturday-car will pick up 2-3 MPH the way it sits!!

Dave88LX

Thanks s346k, I hope that it does!

Mike, you think there is 2-3MPH in just the track/air? Damn, I will be a pig covered in **** if there is.

Mike Morris

Yes-ask around. Cecil is a good 2 MPH faster without doing a thing -been that way for me since 1992 with all of my cars. Good on a Saturday or Wensday. Friday prep is terrible

I have seen my best times at MIR.But that's the only 1/4 mile I have ran at..How far are you from MIR..

Dave88LX

Awesome, I can't wait to get there on a Wednesday night now! My "Ford friends" are surprised it's even hitting 114 MPH, they were guessing in the 107-110 MPH range. Nice.

I live between Annapolis and Baltimore; MIR is about 80 miles from me.

MIR is 50 miles from me but everyone I now gets the PB there if its a 1/8 or 1/4 mile time.. Its only 78 feet above sea level I think..

Fast T

Congrats
