I finally beat a ls1. I was on the freewat and noticed a real nice black ls1 trans am with true dual exhaust, or at least it looked like it. I get next to him and get on it. Then there's an opening. I honk three times and punch it. I have a M6 and instantly put a car length on him. His car was an auto though it car downshifted and just stayed at my back bumper up until 110 115. Then we both backed off due to upcoming traffic. But I had him from 50 to 115mph. Not bad for my LT1. I've raced M6 ls1 and that's another story. They start pulling away from me after third gear. All I got now is a CAI, but I think it helped me quite a bit.

 

The outcome is definitley not the norm....but good kill.

 

mhhhhhmm.... i see

 

I don't see how you can tell if a person has true duals by looking at them while they are driving. All LS1's came with dual exhaust tips out the back if that's what you meant. Was he real loud? Because true duals are usually associated with LT's, no cats and free flowing bullets. If that was the case then the car would likely be trapping 107+ which would make this outcome kind of unbelievable.

Good kill.

CAI's are good for about 5-8 rwhp. That said you're trap wouldn't have gone up by much so lets say 101. Stock A4 LS1's usually trap 102-105 depending on year and which gears they have.

I know that with my 3.23 gears I had a real bad dead spot from 30-50 (prior to the converter of course). It puts us in the bottom of second gear but well below powerband. No offense but I'm guessing the 50 mph start explains why the auto LS1 had trouble reeling you in or even pulling you right at the start. I know that I never wanted to punch it unless I was under 31 or above 54. Inbetween kind of sucks.

But take no offense. It was still a good kill.

 

Hey, its the ***** fackin street, the variables of each car, how strong they run, the drivers, worn out parts, etc... I mean cmon you can't possibly break down the mathmatics of it every time darren.


Yes, the LS1 should have won by a length or two, but it didn't.
Can't you just say, 'Good Kill' without explaining why it happened the way it did?

OP, good shifting and nice run.

 

LT1s are slow.

(joking)

 

NIce kill man, LT1's may be old but they still hold their own on the streets.

 

cool run

 

Whenever two cars race one of two things happen. Usually the faster car wins in which case there is no point in stating the obvious. Or sometimes the faster car loses. When that happens there is always a reason.

By telling him why he beat the faster car it gives him some knowledge that he can use in the future. One it won't make him scratch his head when the exact same race with a similair car walks away from him because they started at 60 mph (not a dead spot). And two it tells him that he should always try and start a race against auto ls1's in the 35-50 mph range to give him his best chance at having an advantage.

And I did say good kill. Twice actually.

 

Actually guys., I kinda figured that I beat him because of the gear he downshifted to. He was at a bad spot. I could tell that when his car downshifted, it didn't downshift enough, because it sounded like he was at around 3400 rpms or so, but I was at like 4500 or so. I don't remember exactly, but I know he eventually would have caught me, but it was a matter of time, which in his case, he didn't have enough time because of traffic. But for the guy who asked if he had true dual. Yes..he at least had a dual catback because his pipes were kinda hangin low and there were two coming from the middle of the car all the way to the tailpipes. It did not go into on muffler. I'm not an idiot. His car did sound pretty loud, but still restricive, like he probably still had cats on and probably stock exhaust manifolds.

I know it sounds odd. I thought for sure he'd whoop my *** because I've raced stock six speeds and they start leaving me after 60 or so. but hey..I gotta take a kill for an ls1 when I can get one. It was really close though...it's not like I pulled on him...I just got he better start and it just stayed that way. And part of the reason the auto ls1 traps a little higher than a stick lt1 is because of the better launch from a dig. I think stock 4 stock from a roll, it's pretty even. I know traps are usually the same even if the 1/4 mile et's are bad, but there can be a 1-3 mph difference. I know that when I launch bad , my trap is like 97-99, but if I get a good 60 ft I trap at 100mph, but I think I'll trap around 101-102 with the cai and a good 60ft. So I guess if he was stock it would make sense, but he did have an exhaust, so I don't understand why he didn't pull on me. Maybe he just put on dual mufflers with the rest of the exhaust being stock. I don't know....

The real point is...I won.

 

good kill, and nice lookin car.

 

it is still hard to believe w/ your mods! Thats all I'm saying, either way a kill is a kill!

 

good kill, yeah if he was an auto at 50mph you caught him in a dead spot.

 

hey sh*t happens! good kill man

 

I have readthat many times... 50mph = bad spot for autos.

 

Good kill man...
Put some mods on that beast and go after 6 speeds!

 

50mph is not that bad of a spot for an Auto UNLESS it was a 2.73 geared auto.. For me i have 3.23's, and a 50 is not to bad of a spot in 2nd gear. I think im at like 4k-4500 rpm @ 50mph.

 

I never paid attention to my rpm but I know there is a world of difference for me at 55 compared to 50. Granted it's not as bad as say 35-45 mph but it's not snapping my head back like 55-65 mph punches do either.

I can say from my personal experience with a 3.23 geared car that 0-30 and 55-70 = but 31-54 = Give or take a mph. When you take the fact that 50 is still in the dead spot and add to the mix that the 4L60E takes a split second to downshift it makes perfect sense why a M6 LT1 could take the advantage and take the win.
