Straight Cut / Dog Gears In Rb25 Gearboxes

[PLYNX]

I know a lot has been said about straigth cut / dog gears in RB26s to handle the high out put of modified motors but what about the RB25 gear box ?

The RB25 box is said to take about 400kw, but what about after that ?

Has anyone had this done ?

How much stronger do the gears make the box ?

Costs involved ?

And what are they like to drive ?

Thanks Guys and Gals

the internals of the rb25/26 boxes are essentially the same thing. Refer to the rb26 discussion
