Default When will it break????

I have a 2002 Z06 that I bought from a guy. It has about 440 hp at the wheel. It is fast now, but may add more. At what hp are people breaking rear ends with drag radials? The only thing he beefed up is the clutch and valve body. It has not seen the track since the mods were added, but I would like to go just to see what I can do. Want to make sure the rear can handle that much hp with drag radials. Thanks.

"The only thing he beefed up is the clutch and valve body."

Never saw a Z06 with a valve body!

Sorry, wrong vehicle. Just a stage 3 clutch.

Hard to say when things might break. Obviously the more you add in terms of HP the greater the chance of breaking something unless you beef up the rest of the drivetrain.

as long as you arent launching at 5000 rpms with a complete clutch drop I imagine you will be alright. It's when you engage the clutch instantly and are transferring high hp which you would be at 5k rpms that you break stuff.

Rev to 3500-4000 and do a nice slip of the clutch and go, dont go to break any records or you may need a tow back, that's even on stock hp with a good clutch and drs I believe

My buddy snapped a half shaft at the track in his stock 05 as he was launching at 5k, so the slip will save your setup, if you launch at high RPM even high dollar parts tend to break in six speed Vettes

You are already at risk, so be prepared if it happens. If you don't get the launch right, you could easily snap one of the output shafts. This is a known problem/issue when running MN6 w/drag radials.

In another thread someone said to get a trans. brace and output shafts. Would an aftermarket differential solve that problem, or would I still need to change the output shaft? I assume getting a brace is just for wheel hop.

An aftermarket differential will only solve the problem if it has the upgraded shafts. You want to do all you can to prevent wheel hop. I have seen the rear trans axle destroyed from it. A friend and fellow member mowton can attest to the damage that can occur when things go awry.

Your future looks very good!

You will need a ton of RWHP and RWTQ and a set of very sticky slicks and a 5000+ RPM launch and an absoloute "HOOK-UP" and you might bust the input shaft or one of the out-put shaft

Really, these tranny's are awesome and take a pretty good beating and can handle a huge amount of power - take a look in the Performance result section and the FI section and you will see alot of fella's putting out 700+ RWHP on their rears

I am making 701 RWHP and 582 RWTQ out of mine, my rear is from a MN6 with the 3.42's I run a A4

Thanks,Matt
