First run in the formula

[Tx98Formula]

I went to the local track today (1/8th mile). This is my first time having the car out there, i've made a couple passes before in my truck and a bunch on my old bike.

First run was my best run

Reaction-.5232
60ft----- 2.07
330ft---- 5.71
1/8th---- 8.69
MPH----- 82.74

i could not get my 60ft down at all, best 60ft was a 2.06, every run after the first was either 8.8-8.7 all mph's were 81-82. I was hoping for some better times, there was another 98 T/A out there with just headers from what they said and it was running 8.2-8.15 with MT ET streets. I have new BFG KDW 2's on the back, first run had about 38psi after a couple runs i dropped it to 25psi and it didn't change anything, my buddy said i wasn't spinning at all but the car just seemed very weak off the line. I was launching with rpms between 2-3k, first run was at most a 2k launch.

anyone have any input to get times down, besides better tires and such? Once i receive my income tax check i will be putting a circle D 3200 stall in it, all current mods are in my signature.

Do you have TC if so was it on or off. Try leaving off idle thats when my car runs its best at. I have a stock stall/and 273s I have street radials to.Iam running 8.5s@85mph with a 1.9 60ft.

[Tx98Formula]

no TC in the car. I'll try launching like that next time. That first pass i it was maybe 1500-2k rpms when i launched and it was my best time, every pass after that i brought the rpms up more. We will find out next weekend!

[EVIL-LS1]

OK keep us updated.

On a 6 speed I previously had with a LM, the best 60' I could manage was a 2.3 and I ran 8.91@86.xxmph. I could never hook worth a damn... ever that night

Friend of mine had an A4 LS1, when it was stock down to the paper filter on some aftermarket heavy chrome wheels, it ran 8.3@87mph.

Those trap speeds seem a little slow to me from all 4 LS1s I've seen run at the track. I've yet to see one personally trap slower than 85.6mph that was bone stock to the paper filter. Try to take out your filter next time and see what happens. Worth a shot

Tx98 - You said all mods are in your signature, but I don't see your sig

[Tx98Formula]

Oops. Guess I didn't save my sig... It has LT headers, manual cutout, ngk tr55 plugs, msd wires, slp lid, k&n filter, mail order tune, 3.73's, and new bfg kdw 2's.

Maybe the full tank of gas was hurting me, but I don't see it hurting my mph and et that much

get some drag radials and that should help.....the stall is really going to help. I cut a 1.68 60' last year on my way to a 7.58 1/8 and 11.89 quarter.

When mine was bone stock mine went 9.03@79mph at Sumerduck and 8.88@81mph at Colonial beach. Low MPH is probally from having 273 gears..My 60ft was 1.9s.My car just went 8.6s@83mph at Sumerduck with 2.0 60ft and 8.5s@85mph at colonial beach with 1.9 60ft.

I don't want to kick a dead horse, I was just stating what my car and Gunz's car ran in stock trim. Gunz's car was a 2.73 geared A4/LS1 as well, couldn't be any more stock at the time either. Unless you're counting those big 17" aftermarket wheels

I was dissapointed with my time but once I saw what he ran with hardly being 1MPH faster, I was good, just knew I had to learn how to start launching on street tires

Doubtfull. When I ran my 70 formula in pure stock we had to use stock street rubber. That meant F/70-14 bias plys.
When in a limited traction situation, a full tank of gas or close to it is a blessing.

At first I was thinking like you, but when I saw all the fast guys in the class running with full tanks, I didn't argue. Sure enough, my best 60 foot times and quickest ET's were with atleast 3/4 tank of gas or more.

I'm going back tomorrow night so we will see what i can get out of her.

Good luck..

i al ways ran on 1/2 tank of fule just so my pump alway would be wet...

and it seems like the 1st gear clutch is slipping.... if ur coming outt the whole and not spining some thing is wrong if the car is just laying down

[Tx98Formula]

I went back tonight, here is the best run i had

Reaction-- .262
60ft------ 2.1
330ft----- 5.75
1/8th ET-- 8.72
1/8th mph- 83.15


for that run i launched from an idle. The other runs i would bring the rpms up to about 3k right before the back tires would start spinning. It would spin a little bit when i launched like that but not to bad at all, but i pulled worse ET's like that, i brought the rpms down so i didn't spin and still ran about the same. Seems like the car likes a very low rpm launch more than anything. I know i need a stall but it still just seems like something is off with the car.. i'm thinking its my tune..

[MrMasterCraft]

That MPH seems a little low to me as well. I'm guessing your "mail-order tune" was done in accordance with your LT upgrade and more than likely the other little stuff? If so, you should be trapping ALOT higher than 83.xxmph...

[Firebirdjones]

Looks about right to me. When my auto LS1 was running in the upper 8.60's in the 1/8th it was trapping 83.xx mph too.
It ran 13.40's at 104-105 mph on those same runs. 3,820 lbs. race weight and 2563 ft. DA according to the timeslip.

Appears he is running right on par with stockish LS1's.

I've got two times posted above for "stockish" (only exhaust) LS1s. My previous, and buddy's previous. Can also remember another guy that had full exhaust on his LS1, not tuned, and ran an 8.1 in an M6 '01 WS6.

I would say it could be the elevation of the track, or you guys just got some slow LS1s



















ok ok, don't get upset I was JK

Jimmy, we still need to run

[Tx98Formula]

UPS finally dropped of my LS6 intake today, as soon as i got home from work i put it on!! took the car down the street just for a quick run and couldn't tell much of a difference right now, but hopefully this weekend i'll see a difference in ET's if i get a chance to go to the track.. Best so far is 8.69 1/8th hoping to see 8.50's would love to see 8.40's, but we will see..

[Tx98Formula]

with the '01 ls1 you also already had the ls6 intake.. maybe that is the key factor here, lol.. i'd love it if just adding that LS6 intake made that big of a difference
