:help: how much power can A4 stock tranny take?

**djvaly** · 02-21-2007, 01:34 PM

it's ok I can always swap to 3400 or 3600 if I need more stall

but thats going to cost you more money to do it over again.
i would really hate to see you make the mistake i did and not get a slightly bigger t/c.
email any ls1 tuner, pretend like youre going to buy a ls1 heads cam package and you also want a stall and ask them what they would be a good fit.

I'll call around and see wassup mate, I'll call for some second opinion of a stall with the G5X3 cam which is slightly aggresive.

please do email/call. 3000 is a to small for that cam.

yeah, the mechanic at LG Motorsports said going 500rwhp on stock 10 bolt and a bigger stall will create more heat and strees on the rear end... so he recommended 3000, but I will ask for more shops to voice in see what they say. 3000 is acceptable but if I can have 3400 and still be safe on the rear end bolt I'd go with that...

anything over 400 and sticky tires youre fucked.

ya ... I'll drive it carefully, I heard some folks on this site doin 450rwhp-500 and taking to the track and they are ok on the stock bolt. what saves me is the A4, less stress on the rear.

problem is the stock trans wont hold that power either. two of my buddies who post on here have rebuilt there trannies several times and neither is at 450 rwhp.
people doing 450+ are on borrowed time with a stock drivetrain.

I sent the tranny to a tranny special shop to build it to hold to 600rwhp.
LG M uses them all the time and they said they are really good, in Indiana somewhere... yeah I'll ask around on the stall with cam vs. stock bolt question

**Frankthetank** · 02-21-2007, 07:38 PM

I just blew mine with only 6k on mods i have.....(see below)
They are pretty weak man......only 364rwhp 400rwt here and blew it....
Blew my 3rd and 4th clutches and bands

FYI:I am looking to build up the tranny eventually in a year or so when I get more money.

Yep, thats the whole reason why GM put torque management in the tune of these cars. It doesn't take much. I also agree with NHRAformula,,,the stall speed of 3000 or 3500 won't make any difference on whether your rearend will last or not. With the kind of power you are talking about, a rear upgrade is necessary and makes the car much more safe. Loosing an axle at high speed is no fun, and whats worse, is depending on how the rearend breaks, it sometimes will take the transmission with it.
I personally prefer to start modding a 4th gen from the rearend and work myself forward. Larry.

**djvaly** · 03-02-2007, 07:57 AM

that's about it. next a procharger and 12bolt... but a few years. I am getting 17X9.5 and 17x11 new wheels and tires but that's a 1k or so.

**djvaly** · 03-07-2007, 07:55 PM

I decided to go stage 4 built up A4 tranny, vigilante 3000 stall, 3:73 gears...
with G5X4 cam

and 402 ls2 stroker motor.

check out my photobucket I created today with all the pics @LGM. I will upload videos of my dyno pulls on youtube.com tomorrow, I get errors when uploading videos on photobucket.
