HOW MUCH POWER CAN A TYPE 3 GEARBOX HANDLE?

Post by John C »

Ok Gentlemen, I?ve had conflicting advice from some eminent gearbox reconditioning firms and so I need a straw poll from the streets ?i.e. your opinion.

I?m putting a 157Bhp highly tuned (and peaky) 1700 Crossflow into a 550Kg Caterham-alike kitcar. I ran a Type 3 box (from a Cortina MkII 1600 GT so it has nice close ratios) with a 110-120 Bhp Xflow no problem, but will it last under the power of the new engine?
The box is as shown on this page:

2 of the gearbox firms reckon the box it will only handle 140-150Bhp tops.
A 3rd firm reckons it should be OK up to 160-170 Bhp.

What do you reckon, and what power have you put through a Type 3 box?

Don't know if this helps cos never used one but I'm pretty sure its basically a single rail version of bullet box (2000e) so assuming power levels similar. Same input shaft etc. Think i read this in Burton mag if anyone can confirm.

Yes, according to the Burton site you are dead right.

What sort of power do you dudes put through these boxes then?
