ok, one know it allwho knows nothing about drag racing at a time.
formula, you need to learn some basic definitions before you talk about torque adn ho wit applies to acceleration and drag racing.
go read this, it eXplains it all PERFECTLY. Its a little long but its got alot of good info

The following was taken directly from your link (which btw said nothing about "squat"). As you can clearly read, it states, quite obviously that the lesser horsepowered L98 has the ability to launch at a slight advantage due to peak torque at a lower rpm, but it goes on to say that LT1 still has the advantage because of more average power. You just lost your own argument as the M275 has more torque, flatter powerband, and more horsepower...

So, in a drag race, the cars would launch more or less together. The L98 might have a slight advantage due to its peak torque occuring a little earlier in the rev range, but that is debatable, since the LT1 has a wider, flatter curve (again pretty much by definition, looking at the figures). From somewhere in the mid range and up, however, the LT1 would begin to pull away. Where the L98 has to shift to second (and throw away torque multiplication for speed), the LT1 still has around another 1000 rpm to go in first, and thus begins to widen its lead, more and more as the speeds climb. As long as the revs are high, the LT1, by definition, has an advantage.

I was being a bit facetious. Father was a professional, as in paid the bills with it, IHRA and NHRA drag racer. My brother is currently in the SuperPro NHRA point standings but he's more a weekend warrior with a full time job. I practically grew up at MIR and Capital dragways, quite literally. I ran the water box at Budds Creek when I was like 9 years old. I know a little something but don't claim to be an expert at anything. But to say torque has nothing to do with it, made me raise an eyebrow.

so by the time both cars are moving fast enough to apply full throttle, the tq, as i said before means absolutely SQUAT. The maximum amount o tq that can be applied to the car without generating tire spin is way less than a sl55 or 600 will make. now see if you can follow this, i will try to sum it all up for you here so pay close attention.
the graph i showed before shows the sl600 .4 tenth faster from 100 to 200 km/h but every written comparison of the 2 cars says they are just .1 different in the full 1/4? now why is that?
i'll tell you , the 600 cant use the extra tq it has in a drag race, it makes it all down low like 2500 rpm. run your car in the quarter and unless you mess up BADLY, once you passt he 60" you wont fall below 4k, probably closer to 4500.
in the roll on from 100kmh to 200 the car is sitting at probbaly near 2k rpm, and when you hit it you can use the gobs or tq it has.
is that clear?

If you grew up at Englishtown and spent a lot of time at MIR, then you surely know Tod Mack. He owned MIR before Royce and is/was a friend of the family. Don't know how old you are but if you were big in the East Coast drag racing scene in the late 60's early 70's, you've no doubt heard of my father, Jim Dunn.

if memory serves me, there were 2 jim dunn's one is related to mike dunn. i think they were west coast racers. the other was east coast , i assume thats your dad? i was very big into the mustang racing, what became pro-5.0 in lateryears from about 92 till about 99. i was based out of etown till about 87 then i moved to ct and had to split time with lebanon valley. with an occasional outing at atco. i ran the true street classes with a 10.50 street car, and that was pretty fast then. my fiance at the time was the niece of george greco. but i got my start racing with the grecos, joe amato( not that one, the other one the mustang one) bill devine, storman norman,( i see him once a week it seems) adn all the big mustang guys at the time. i am friends with a lot of the current guys still running it as well as a bunch of 10.5 guys down here.
anyway, ask your dad if he know dick murray, he was an nhra announcer and track manager and racer from the 60s. he was a chrysler rep too. he is an old guy who worked for me down here who knew EVERYONE from the 60's. he manage brainerd for a while

Ever heard of GEARING? I had 3.90 DTE gears in Auto A-4 trans, every bolt-on available etc.. They trap low but haul the mail...

ohh and he had drag raidals..you didnt
and what is your definition of every bolt on available? heads? cam? what did you do to get the whoppin 410 rwhp out of an ls2
and please, enlighten me as to where i am wrong about the torque? im all ears.

ok, so not you are going from 1.9x to 1.90? still doesnt matter. it doestn add up his pass is more believable with a 1.8 60 to your 1.9xxx . and he is well over 120 mph which is what you need to do it. you arent gonna go 11.7 at 119. with a 60 in the 1.9 anything.

i told you, i thought i had my slip, but in realty im probaby chucked it, i dont keep 12 second slips like they are fast.
and please, i dont know corvettes? how do you think i knew you were full of ****? how many passes you have in a ls2 c6? 5? 10? i have probably 2 to 300. and mine are in a m6. i know what it takes do do what you are saying adn i know you didnt do it. how come on dragtimes every vette that had a 1.9 60 and went in the 11's at all had a trap speed over 123? and you did it 119? that car you want to compare to had a better 60, et and trap? and he needed drag radials, but you did it on reguar tire. riiiight, sure you did

It's not my fault you have no concept of how to launch a car...
But, I'm going to heed my own advice here: "Never argue with an idiot, they will only drag you down to their level and beat you with experience."
-And on that note...I'm out!

TAKE YOUR POS TO THE TRACK AND VIDEO TAPE YOUR BEST 60' ON STREET TIRES, I GOT $100 THAT SAYS I CAN BEAT IT ON STREET TIRES, AND ILL MAKE SURE THERE IS VIDEO OF THE WHOLE THING, INCLUDING THE TREAD OF THE TIRES HOW ABOUT THAT?

Yes, he's the East Coast one. Here's my brother's 8 second Super Pro car. These were taken a couple of weeks ago when the show Pass Time (Speed Channel) came to MIR. They asked him to run his car for them. Airs in Feb.

nice, i just cant get behind that show, im not sure why but its just not that entertaining to me. plus anyone who knows drag racing has a huge advantage. i havent seen or heard yoru brothers car, or asked him any questions and i already know the car goes 7.51 to 9.99 in the window somewhere, give me 1 question and a look at the car and i knwo i can get it closer than that. looking at the guesses if the guys up there at 9.20 to 9.30i bet they are pretty close but i migh say a little quicker, high 8's like an 8.80?
how did i do at the home version??

I think he told me that he had some tire chatter or got out of the groove or something on this run though. I can't remember exactly, but I think it was either 8.9x or 9.0x

whoa this thread has morphed way beyond the OP's wildest dream of post count haha lol!![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)
I'm planning on being at MIR on 10/31 as well. My car is basicly bone stock now; had the LET stage 1 flash but that did nothing to my car...drove it, then they flashed the ecu, then I drove it and it felt exactly the same, no change whatsoever, even tested it on a roadcoarse and it felt the same...going to get it tuned properly down the road after mods (still not decided on which tuning company I want to go with) etc...etc... I have street tires also 245F/285R
Now I've never drag raced before, not even once...I've been to the drag strip many times but just watched...so I'm a total newbie...I plan on trying it though. I also want to take a ride in some cars down there and have an experiences racer ride with me to instruct me for a few runs so I can learn.
My experience is on the road course...I've been racing on circuits since '04 in BMW CCA, club and NASA GTS series, my race car is a BMW M3 Lightweight (LTW) full touring car chassis and IP series regulation engine...and I instruct for many clubs at their events...Porsche, BMW, Mercedes, Ferrari, NASA, CG etc...
I can say that I like the SL55 on a roadcourse, it was lots of fun...consistant straight away speeds and braking (it's weight requires you use a very good pad and fluid combo) and fairly predictable handling characteristics....understeer on entry, flat through mid corner and puts the power down well on exit...it's a heavy car, it's hard on tires for sure! But it's no GT3 RS out there lemme tell ya haha lol!
