Ive used some of the calculators online but not sure how acurate they are.What im tryin to figure out is why the track I race at is so slow.Ive talked to alot of guys at big events such as Fun ford weekend or super chevy that complain about there cars losing as much as .5 from there home tracks.
The track is Bristol Dragway located in Bristol Tennessee.
Ive talked to a few locals on this board that complain about how slow it is.The track sets at 1450' above sealevel.
I done a calculation on a 90*day and came up with 4000'.Does that sound right???
My car in bone stock form a4 2.73 gear ran a best of 14.50 @98mph on a 90*+ day.I since done full bolt ons and gears and tune and went 13.4 @ 104 i couldve done a little better but the weather was crap.

Most ls1 cars run low 14s stock and ive seen a couple dip into the 13s not many though.
My main question is is the altitude the reason for the slower than normal times???

Bristol is an ET sucking abyss lol, it runs uphill (1% grade) and in the summer the DA can run from 3-5000 feet. I usually run about .3 in the 1/4 slower then Bowling Green, Steele, Rockingham or Carolina.

Plus the prep sucks on 'street fight' nights, nice facility though, but they open late and close early so 'good' weather days are far and few between..

Dang, 14.5 at 98mph? I race at Bristol also, my bone stock '98 A4 ran consistant 13.6's at around 101-102mph in hot weather and my bro's '98 M6 ran just alittle quicker when it was stock. I never hardly see any LS1's in the 14's there unless they just spin like crazy or cant really launch the car. Bristol is a slower track for sure with being uphill and the DA.

My car went 14.30@98 when it was bone stock with a 1.8 60' on street tires. Yes, the Density Altitude will kill your times. I went to Crossville dragstrip before the headers and cam, at Bristol I would run 8.5's, went to crossville and ran consistant 8.2's, went back to bristol running 8.5's again. Back in 2000 at the GMHTP race, the DA was 4800 above sea level. PSJ was running 11.7's where he was and when he ran at bristol went 12.4's, went back to his track and went 11.7's again.

you must have a strong car.my buddies 01 ss ran a best of 14.0 and he has alot of experience.my car was in need of a tune up but i dont think it wouldve got out of the 14s.a guy i used to work for had a 99 ta and it went 13.7 with only a gear when i was gear and lid the car was in the 13s.but 14s stock.im there alot at the street fights and rarely see stock ls1s in the 13s.
my mustang has everything but heads and it takes a 150 shot to run13s.
the track is so nice its hard to complain about the slower e/ts.

It's alot on the driver too like I said... one of my friends over in TN(mod on here, OneMeanZ) ran 13.0ish at bristol in his 6speed trans am with just a lid, 4.10, and DR's. I dont really think my car is that strong, just get outta the hole good and your set. The 13.66 run was with a 2.01 60ft, so I dont see how the guy above me ran 14.3 with a 1.8 60ft unless he just had some major problems. 1.8 sixty foot is crazy on street tires at bristol. Sounds more like he had a 2.8 with that run, haha. Another guy I know that just sold his '99 SS awhile back ran 13.00 at Bristol with DR's, 4.10, lid, catback. His car before that was a '99 T/A and it ran 13.7ish stock also.

yeah 4.10s and stickies 13.0 i can see like i said my gear helped alot.my car was gown on power as well but i dont think it wouldve hit 13s with the 273s.they are guys in florida runnin 12.90 in bone stock form.my 60 was a 2.0 with no tire spin.
some of these cars do run better than others.
ive seen more 14s ls1 cars at bristol than 13s in stock form.
what gears did your car have??

I've been going to Bristol since 1981....kp summed it up...ET abyss.

My Firehawk ran 13.5 at 105 with headers and all the other bolt ons and crappy BFG's.

Added Incon twin turbos and a mega built engine and went 9.9 at 141 at the last event last year....before the rain started...

Great track...sorry prep on Street Fights...sorry air...ET eater.

I must appologize, I posted the wrong 60' in my original message. Kept thinking of what I ran last and that is what stuck in my mind. Ran a 2.1-2.0 best 60' on the stock runs. My car must have been pig rich from the factory because everything I would add that would lean it out made it pick up more than my buddies car that ran the same times and added the same parts. This is the breakdown of my mods and times.

14.3 run=bone stock mph 98 60' 2.1-2.0
got seat time=14.1 mph 98-99 60' 2.1-2.0
Borla=13.9 mph 99-100 60' 2.1-2.0
added lid, FRA=13.7 mph 100-101 60' 2.1-2.0
more seat time, good air=13.6 mph 101-102 60' 1.9
added ST3500=13.2 mph 103-104 60' 1.82
added 222/.566 112 cam, hooker headers, ORP=12.85 mph 110 60' 1.85
added E.T. streets=12.70 mph 106 60' 1.77
Car is still untuned

Been racing at Bristol since 1997 and I have seen stock LS1's run anywhere from 13.7-15.4 depending on the weather, driver, and track prep. Saw a guy with a red LS1 camaro(on test drive from dealership for the weekend) thrash the crap out of it all night trying to get into the 13's and the best he could do was a 14.1, best mph was 98. This was on a street fight night. He still had the dealers tags on it! His buddy went with him with a rented vette(don't know the model) and he did the same thing but best he could do was a 14.3. Last I heard guy got busted in the camaro when a sales rep was there watching the street fights and recognized the car and the tag.

No problem, I will look around in the thousands of slips I have to try and find a few. I've only ran in the 14's once with this car, and that was with a 2.6 sixty on some bald tires and was just goofin off. Bought it with 60K on it back about 40 years ago. I'm at the track EVERY single weekend running my '88 T/A, I have plenty of seat time to back up my ET's. Like I said, my friend with just drag radials, 4.10, and a lid ran 13.00 in his M6 LS1, so it shouldnt be too hard to believe mine ran 13.23 with drag radials, lid, catback. Unless you misunderstood and think that I ran that on street tires, which I didnt, they were M/T Drag Radials, only got to use them one time, and borrrowed them off of 1SLOWSS(dont know if he's on this board or not). Everytime I'm at Bristol I see plenty of LS1's in the 13's, maybe we're just there at different times, haha. It takes alittle practice to run there.

no prob,i thought you were on street tires from what ive seen the 323 geared cars seem to run a little quicker.most of the time im there its on thursdays about 100 degrees.
you racing every weekend you probably know alot about the track as well.the day i ran the prep was so bad i about know i couldve went faster on street tires.no matter what i done the et streets would not hook up.
where in va are you im in lee co

mine was the opposite lean from the factory.i had to get the car tuned to stop detonation after doin boltons.ive also noticed some of these cars run better than others

I dont run every weekend at Bristol, but at Rogersville, the 1/8 mile track. No street tires, I couldnt get under 13.6-13.5 with them. I'm like 20 minutes away from you in Big Stone Gap. You on the local board? I jhad detonation from simple boltons as well, still have it.
