Should I be worries about over powering my gearbox? on the normal car which weighs 1200kgs the stock gearbox is rated to around 250hp and I will be
running 300ish ~& r888's However im hoping that as the cars going to be half the weight it wont be possible to put it under the same load?
Do i need to look out for an OS Gilkin box of will my standard be okay?
Don't worry, be happy.....
What box is it? Whether is will break will depend on how close to failure it was in its original application and what the failure mode is.
For instance, standard cossie 4x4 box dies at about 300bhp and because 3rd gear fails. in a locost you can still lay down 300bhp in third so it may
still fail.
If the box is known for shearing the input shaft on a hard launch in a heavy car, then in a much lighter car youll probably be ok.
I have been running 320BHP through a type 9 for 2 years doing track days and santapod not broke it yet, i think its because it breaks tracksion first. I am also on R888s.

It's torque that breaks things. Think of high HP bikes and their tiny gears and chains, but not much torque.
