what do you mean how hard they push it? Not really dumping like you do with an m6. I've tried stalling and flashing off the line and my 60's are always pretty close 1.69-1.71 seems to be my average with MT's. I've beat the piss out of my tranny really.

what i mean is like how much HP can you put to it before things start to break

[redbird555]

Lets put it this way the 4l60e is only rated to 380ft lbs of torque a stock ls1 is either making or very close to making that stock because they are rated at 360tq. Now throw on some bolt ons and youve well exceeded the limit however people usually dont have issues unless theyre beating the crap out of one. the trannys are really a crap shoot some go on stock power others take 450rwhp abuse and still go...

That is not enough to really say hay, my trans is now going to go out.

4L60e's are weird... they can last 200k miles or 15k miles. Ticking time bomb. Some have held up to crazy hp, some break on stock hp. So I wouldn't worry to much about it.

Yeah i hear ya. hah it is what it is man if it break it breaks its all part of it

[Zinergy]

that mph was enough for a high 11 low 12 run with a good 60'

That mph is insanely high for stock ls1 car. 111mph is what full bolt on ls1 cars hit.

I wasn't stock on those runs, i had the 221x221 561. life cam, ls6 heads, headers and 3.73 gears. Car should have ran faster if I cut a good 60' then the 12.6 run, but it was only 1 pass that I got to make on that set up. Car will get a moser 9" and be really nasty on launches. Should hit very low 12's possibly high 11's with my new set up and 3.70ish gears in a 9" rear end when I get it.


with out headers and no drag radials on my old cam and ls6 heads I hit the best of a 13.10 @ 110.7mph with a 2.1 to 2.2 60 foot. so it was already an easy 12 sec car to begin with.

I had several 113.4 traps with cai/exhaust. . .stock cam, never had valve covers off until after this... granted DA was -440's that night 1.74ish 60's help.
