just wondering what does a stock LS1 run? i was thinkin around mid 13's at 103-104??

there is also a guy there that has a bolt on 01 SS that runs high 13's at 104, but his is an M6, and i dont think he can drive.

there is a guy there that has a supercharged LS1 ws6 pushing 9lbs of boost running low 12's at 112

the track is known to be slow, but i didnt think this slow? i was expecting to trap at least 110,
keep the input coming, i like critizism (constructive)
thanks

robbie what track do you run at?
i run at Bristol dragway TN

 

Those runs were at Darlington. I set it up so when I was on my way back from vacation I could stop in Darlington, stay a night there and get some 1/4 mile runs in since I live so far away in Greenville. I still couldnt hook up on it. Im gonna get some BFG DR's and try to take another trip soon. Im gonna try my 100shot N20 out with the DR's

 

Spinning does and will increase mph but lower ET!

 

A buddy of mine thats on this board ran 12.2's with just bolt on's, 4.10 gears, 1.6 rr's , 52mm tb, and some BFG dr's. Also, some weight reduction.

 

Spinning has never increased my mph that's for sure. I trap at least 1-2 mph higher on dr's and et streets. Think about it...at a given time, you are hooking better and have therefore had more time to accelerate. This spinning higher mph myth has always baffled me. I've NEVER seen it happen even once in real life.

 

This is a flawed theory. Give me one ounce of proof - ie, running on slicks and street tires on the same night and seeing a MPH improvement on street tires. I would love to hear your rationale. It makes no sense.

I have consistently trapped 1-2 mph higher running on ET Streets (13-14 PSI) than on street tires.

Cutting a better 60' means you are leaving harder and in turn accelerating faster - somewhat of a slingshot effect.

People will argue that spinning allots you more time to accelerate because your ET will be slower - that is NOT true...the distance being covered is the same regardless of how much you spin or hook, but hooking makes the car accelerate harder/faster, increasing your speed through the traps.

 

I've never trapped higher on a run where I spun vs. a good launch on drag radials or street tires. In fact, I usually lose 2-4 mph with a 2.2 or higher 60'. A 2.5 is going to kill your mph and ET. Maybe you'd trap higher with a car on slicks that can "spin" and still get a good 60', but not on street tires or drag radials where spinning means you're hardly moving forward.

 

I know guys that have been drag racing for years and will tell you that spinning will increase mph. Think about it. If you dumb the clutch from a dead stop what is happening? Your mph gage may say you are doing 30 but you are sitting still or slightly drifting. Same thiing at the track.

Im not sure if it happened to my buddies cars cause they had 1000+hp or what, but I know spinning does affect mph.

 

What you said made no sense.

First, there are a lot of misinformed old school musclecar guys out there. I always wind up talkin' to a few at the track and its just hilarious to hear about these old school super fast muscle cars from the 60's that went 9's bone stock from the factory when in reality none ran better than 13's with most in the 14's (besides the rare crazy cars like zl1 camaros and what not which there were what, 69 made). Just cuz they say something is true definitly does not make it true.

Next, I have no idea what you were talking about with your dumping the clutch story. If you hook up, you are going to be traveling FASTER at the 60 foot and therefore FASTER for the rest of the run. You at least have to acknowledge that. Just think about it. It's like having a rolling start vs. another car in a race. You're going say 30 mph at the 60 and your friend is spinning and only going 20. You have a 10mph head start to the end of the quarter so of course you are going to trap higher and et lower.

 

Umm...that makes NO sense. When you dump the clutch and your tires are spinning, of course the SPEEDOMETER is going to read higher..but your actual MPH isn't increasing as fast as the guage reads. Actual speed and speedometer speed are two different things. Once those tires catch, the speedo mph will fall back and read the ACTUAL speed the car is moving. I'm not going to argue this anymore because you have absolutely no rationale behind what you are saying. Go get some REAL WORLD experience with this...spinning kills mph. It's that simple.

 

So you call them old school because they raced 2 years ago? These guys were running 5's in the 1/8 and 8's in the 1/4. Not to old school to me.

 

My buddy ran a 7.8 @ 97mph at the track. Then he ran again and ran a 7.5 @ 95 on the same shot of nitrous. The reason is because he spun. You guys here think you know all but are far from it!

(that is 1/8 times)

 

There are some instances where you can spin and trap higher...I'm not saying it is impossible. There are too many variables involved in drag racing to say 100% one way or the other. However, as a general rule, spinning does not increase mph but rather the opposite.

Your buddy losing 2 mph between two runs means nothing. As I said, there are too many other variables besides traction. Did he hit the rev limiter in one of the gears, have more or less bottle pressure, change to a hotter/colder plug...? Too many variables.

I can give you many instances where I have spun and trapped lower than when I hook and leave hard. Does that mean that 100% of the time you will gain MPH when hooking? No. But more often than not, you will.

I well you what...you take your car out to the track, spray the **** right out of the hole on stree tires and see what you trap. Then throw some slicks on and hit the nitrous of the hole...dead hook and watch your mph go up a ton.

 

Im curious as to how it does? if your spinning and not moving forward as fast then how is it going to make you run faster mph and lower you et?? think about it you said Lower your et's
