What Sort Of Power And Torque

[drgnball34]

ive been hearing all sorts of different mumbo as to how much these boxes can handle. Im aware thats its more the torque that destroys them then power. What power are people running/had running before their's let go? 2wd/4wd/application?

WHONXT has smashed one or two i think, but thats a 9sec car lauching hard on slicks. outside of that i've rarely heard of people smashing them. i'd say abuse is more an issue than torque.

I was told just to be careful shifting into 3rd.

Enough to run a bunch of 9's in a VL. Most street cars can't break them.

i thought that was more an issue in GTR's? afaik they're pretty much the same box as GTS-t's, but doesnt seem to be as much of an issue?

[drgnball34]

i think 4wd would put alot more stress throught the box due to better traction....9sec on slicks...enough said

[Kranker]

4wd does put alot more stress through the gearbox, but people tend to break 3rd gear, and for most cars traction at 3rd gear speeds isnt usually a problem.

Ive got a feelling that there was an actual design problem with the allignment of 3rd gear, selector and gear dont match up 100% or something similar...dont qoute me.

So smashing the box through the gears tend to kill it. Try and avoid very hard and fast changes into 3rd gear, both from 4th and from 2nd, and there is a fair chance she'll hold together.

If it does break id be looking at aa PPG or OS Giken gear set, they dont cost the world and from what ive read are pretty tough stuff

I give mine a fair bit of grief and it seems fine.. might be a different story when I'm pushing 400rwhp and have some slicks on down the drag strip..

[GT51R] was driving around with a 500+awhp r33 gtr with a t51r turbo and it lasted the punishment, and thats with a huge turbo coming on hard n fast.

Plenty of other boys as mentioned with big hp on stock boxes, i wont be overly worried but i would always have a couple of grand aside just incase it did let go

[Phobic]

i have broken a 3rd selector fork but that is from fast aggressive downchanges from 4th to 3rd. other than that they hold together pretty well

[Cubes]

I know of VLT that has broken a few rb25t box's with 350rwkw. Long diff gears + hard launches on sticky tyres = bang. He must give it a hiding.

Mine has held together fairly well. Still nice and quiet.

[craked]

well i just smashed my second one in 500kms with 560hp

[Cubes]

560hp ATW?

Street tyres or? (looks at your avtar)

LOL! Stop driving like a psychopath on the street and they wont break as quick. You're an animal!!

Abuse will kill anything.
