4wd cosworth transmission what power
its been asked before but what would be the max power this transmission can take
no hard hard launches as i will limit myself not to this time
as i had 330 before and kept destroying 2nd synchro
i will be running 3.6 diffs aswell if that makes any difference
ill be looking at aroung 450bhp for the engine will i get away with it if i treat it nice and no hard launches

Most people say 350bhp is its limit
However, ive thought about going above this and asked around before.
If you treat it with respect then 400bhp can be ok.
Not sure about 450 though ?

I would like to see anybody buy/build a 400 brake engine then treat the gearbx with respect ...
Might aswell leave it std
I blew mine with 320 brake... anyway its torque that matters..

whatever power, if you're going to launch the fuck out of it, its going to break.
If you're treating it well.. then I guess 350- 400 will take its toll.. if you have big boost peaks (read.. high torque)

What i'm interested to know is, firstly, when people destroy there boxes with stage 1 and say the boxes are shite, they forget to mention that the car has done about 120k, I blew a greabox into a million bits before, it's not that hard, car had done +80k, got a new box, turned up the boost and it hasn't given me any bother and i do launch it regularly, off traffic lights! Car is just stage 3 BTW. I think 400 would be ok, but not if u just used it for trackdays etc.... time will tell i guess.

I fail to see what synchros have to do with power. Revs and rations if anything. But you would probably destroy them the same if 200bhp and 400bhp, it's a matter of how you change gears.

ok i had stage 3 the gearbox had just been reconned aswell
i had alcon 6 paddle clutch the car did used to get launched aswell
i didnt fast change as it didnt like it so i only doen slow change itwas always 2nd gear sybchro sumtimes 3rd and kept doing my head in when the car was off teh road every 2 months for gearboxes now im thinking of upping thge power i need the car to reliable as its everyday

xr4x4rs itmust be something with gearbox assembling, or gearchange or gearbox oil. I hae no idea how power could influence synchro wear. One or two misshifts can fuck the gearbox up though.
#23

well im going to give it ago with standard boxe and diffs but have them checked over before fitting possibly get the box shot peened i will take my time and see how it goes when it goes i will upgrade but at the minute i carnt afford to

4 boxes
8 rebuilds
in 18 months
i should have bought a quaife box in the first place
one of my "NEW" boxes lasted a total of 23 miles before it went tits up and that was in fifth going along the motorway and not even giving it mucho beans
mind you, the original box i lost 4th gear in
then the next box i scrapped at one of the revs days at brunters
but i've never had 3rd gear go (but i had put cogs out the side casing of the box before and fook me thats something you never want to do )
i did get a guy to build me a box when me and mob did our 5th gear top end mod and that was fine no matter how hard i ragged it
pity the engine made like a chocolate firegaurd and melted 3 weeks later
is there any way that the T5 can be made to get 4wd then?

Then got another box built by Bernie and how it survived 2 years of my constant abuse before 3rd went AGAIN i will never know
Think it all depends on your driving style. I really have no recpect for my transmission and it done well while it lasted
Might be worth a E-Mail/Phone call

i phoned cts up today and they said i would be advised to go quaife box and diffs but looking at 6k which tbh i have no where near that at the minute
as ive said wim going to have to leave it alnoe for now and treat it gently if it goes it goes but no harm in trying with what i have
