rally design reckons something in the region of 195bhp @ 7500rpm for a clubman box or 250bhp for the heavy duty box

Ps: You gotta love the winding noice from the box. I love it

had a few problems with boxes on the rally cars, one's now running the heavy duty 6sp sequential quaife box, and the other cars running a 4 speed SC rocket box like yours and thats a 200bhp 2.0 pinto (because the quaife seq box broke !) no problem so far with the 4 speed

Send it to quaife, they'll rebuild it and tell you all about it for not much money, plus when you fit it you know it'll be as good as new
