Max driveline torque?

[willcaswell]

Hi all, i was wondering how much torque the gearbox and CV shafts can handle on a Golf MK1? what sorta torque are you guys with hotted up motors putting out?

Cheers!

I had a MK1 GTI that did over 150bhp at the crank and that was on std 90mm CV's and drive shafts, My mate has a MK1 Turbo with std stuff on too, that does 175 at the crank.

You'd have to be rough to break them I reckon.

the motor im putting in will have around 300Nm peak torque, i am thinking the box wont handle it...?

You might want to look at a aftermarket LSD, they're generally used for more serious motor sport/general thrashing with lots of power. I don't know if you'll need it though..

Peloquin or quaife come to mind. They're normally about 1-1.5K + shipping from the US/UK, and about 1K installation. Rough figures, so don't quote me. Might be 3K all up.

I take it this in in reference to your electric conversion? You shoud be able to program the speed controller to have a progressive torque curve so you can't get all 300nM from a standing start.

Most likely your tyres will determine the gearbox loading as well as the clutch(if you use one). Once the tyres or clutch are spinning, that's the peak torque on the box.

Should be an interesting project.

Thanks for your replies!

Unfortunatly the controllers where you have that sort of control over settings are a little out of my price range hehe, but the controllers do take a second or so to get to full load so i wont get max torque at a stand still (theoretical stand still is about 340ish).

Was just wondering if when i put some fat tyres on it would the box be up to it? i guess it would probably spin the wheels (no clutch) b4 it chewed the box or shafts, but saying that ive seen smaller output cars snap shafts before (notably a friends swift... 2 so far, and 1 box!)
