ive not had my williams that long, but i want more power out of it, as you do, lol. what max bhp will the gearbox take with out going all the time.
thanks very much lads, id be greatful for your feed back.
For christs sake dont be trying full throttle gearchanges as mine blew up after a day at Brands.
It is the torque you gotta look after as this is the turning force of the engine and is the brute that will shear your shafts. As long as it is delivered smoothly it should be able to handle loads more, remember to do your clutch as well though as if this can not handle it then the power hike will be in vaine.
Well Im running a Williams box in my 16v and its smooth as silk - take it up to 7500 rpm in normal road driving no problems, and quarter mile it with 5000-7000 rpm, full throttle gearchanges and 200+ hp crossing the line, again no problems whatsoever.
BTW one other thing - once you start to really abuse the drivetrain, its always the clutch that will go first before the gearbox anyway. Both replacement jobs are a nightmare, but a blown box is always gonna cost you more.
Yeah they will go after a while, my 16v box stood up to 70k of use including plenty of track days, 1/4 miling and fast B-road use etc. The Willy box is tougher than the 16v box anyway,its out of the R19 diesel.
