Hi,

does anyone know what BHP these can handle? ive heard 400, 450, 350!

going to be running 450bhp (flywheel) any suggestions for a suitable clutch without spending over £500

cheers

 

If you're running 450bhp on a 5-speed the clutch is the least of your worries - newage boxes are good for about 350-400, classics less than that

 

What is your spec

 

My box will be upgraded to Ppg internals soon

 

P1 forged internals,
simtek al/lc,
Md321t,
Rcm headers
Full decat
Fmic

Cheers

 

not entirely true,there are many different types/models of early 5 spped boxes,i know of a few 752 dccd boxes running just shy of 400/400 and have been good.....but yes,generally they are weaker.some of the newage 5 speed wrx boxes are also very weak,and possibly weaker than some types of the early 5 speeds. all depends on what life the box had in the past and also what code the box is as some have strengthened gear kits.

i would also like to know what people are running on the 5 speed pink box clutch.....
im running 338/316,no probs yet,i think they are meant to be rated to 350/350 but im sure there is many other people running more??

 

I was running 360bhp standard exedy clutch and standard p1 gearbox, harsh driving and launches, both feel like new!

 

The torque from the 321T will cause it to slip rather then bhp.

ACT have good reviews

 

standard exedy clutch???
or do you mean the pink box?

what torque were you running?

 

I am running just standard exedy blue box clutch at 360hp/350ft/lb.

spec; vf48, fmic, 550cc, rcm headers, decat, k + n.

....so how about DDM, ac competition, scooby clinic 6 puks?

 

what car do you have?is it a 2 litre,or 2.5?

 

2 litre a the moment

 

what boost are you running?

 

.......21psi

 

around 430-450 bhp and 380-400 lbft

standard v6 sti 5 speed and ap clutch

 

.........perfect

 

not quite....

but i have a fresh rebuilt 6 speed ready to go in its place!

 

Is anyone else running exedy pink box clutches? And at what power?
