hey guys I ran a 14.3 at like 98mph is that normal for a bone stock LT1 A4? just wondering, post up your stock times

 

Yes! Go to the drag race section.

 

Before my mods my car ran a 14.5 so your a little high but with high mileage and worn out parts it happens. Of course new it is faster.

 

last time I was at the track, ran against a 95 A4 camaro, she ran a 14.55, and I had my quickest a 14.44 against her, though I would think your mph would be a tick higher, mine are always 98-99 and that's with 14.4 and 14.5 runs, maybe I just can't come outta the hole right and it can do more. How many miles are on the car, I've just rolled over to 152xxx on mine. But you're on par, have fun with it and be safe.

 

I had a 95 Z28 years ago that ran a best of 14.2 @ 97.8 so my time was very similair to yours. Every stock LT1 I have ever seen run is usually in the 13.9 - 14.5 @ 97 - 100 range.

But that's in the real world. Go read some LS1 vs LT1 threads and suddenly everyones LT1 runs 13.6 @ 102 stock

Seriously, that's a very normal time. Now start modding and say hello to 13's

 

According to your sig you have a M6. Manuals always trap higher then autos because they eat less HP through the drivetrain. I usually see M6 LT1's trap 99-101.

Your 60' and shifting skills will determine how well you ET. Anything in the 1.9-2.1 60' range is considered very decent for street tires. Anything higher and there is some room for improvement. With a good launch, say a 2.0-2.1 60', and fast shifting I bet your car can run 13.9-14.1 with no sweat. Whether you can actually get a 2.0 60' will depend on your tires and how well the track is prepped.

 

The slowest and perhaps the nicest of all my lt1 cars my 94 formula 2:73 car stock 14.3@98 or 97 I cant remeber

95 M6 13.8@100 stock
95 Auto 3:23 13.9-14.0@99 stock
97 TA 2:73 CAI,13.7@102
95 Auto 3:23's 13.9@100 stock

98 Formula auto 13.5 stock
99 TA m6 13.1@108 stock

 

Some numbers would of been nice. But my 96 Z28 at palmdale ran 14.1 to 14.3 . Went to Fontana, Cal. and with tires, ( ETstreet) and a centerforce clutch, Ran 13.5 @ 101.5 Back to Back. Good tires and a good launch is worth an 1/2 second. Every 10th you pick up on the launch in the first 60 foot, you can double on the top end. You won't go faster with tires, maybe a hair slower, but you will be quicker.

 

I think every M6 LT1 car is capable of 13's with sticky tires.

 

motor trend or someone ran a 13.6 at 105 or 106 in a 1996 m6 ss

in a bone stock down to the filter and original street tires

 

No offense but I would have to see that to believe it. I have never seen a stock LT1 trap 105-106. With full weight you're looking at needing around 300 rwhp to trap that high.

Not to mention that a 106 trap is good for very low 13's on a decent launch. I know I managed 13.1 @ 106 on a 2.0 60' in Illinois and the same car ran 13.3 @ 105 on a 2.1 60' here in New York with slightly higher elevation/warmer weather

How does a 305 BHP motor lose only 5HP through the drivetrain? That's less then 2% drivetrain loss. This makes more sense if it was an LT4 but a low 13's capable 300rwhp stock LT1?

 

He is telling the truth. I think it wa car and driver that pulled those numbers its been a while. Not a typical haul for a stock LT1 car.

 

I made a run after a top fuel dragster and i got right in his tracks and got incredible traction. I felt like i had the stickiest slicks you could buy. Every other run i broke loose with 1/2 the throttle. If you were at the right altitude with the right temperature and everything was optimum you would be able to get very good times.

 

I understand that. I remember when one of the magazines reported Evan Smith having gone 12.89 in a stock 99 Z28. I don't remember the trap but I think is was around 108.

Another article might say a 99 Z28 runs 13.8 @ 104. You gotta take those magazine times with a grain of salt. Take either the 12.8 LS1 or the 13.6 SLP LT1 to NYIRP on an average summer day and I bet you start to see some low 13's from the LS1 and high 13's from the LT1. I bet both trap speeds lose a solid 1-2 mph as well.

But even still, I would love to see a stock dyno chart on that 96 SS that trapped 106. I have heard of people getting 275 RWHP from those SLP SS LT1's. But that only equates to maybe a 103 trap speed. Was it all weather and track elevation that raised the MPH to 106 or did that car really have 300 rwhp from a 305 FWHP motor?

I guess that's gonna have to remain a mystery.

 

my 60's are in the low 2.2's on a track that is not known for it's prep, nick named spinworld instead of speedworld, and on 315 Sumitomo htrz's, which I hear are not the grippiest street tires.
