but only if you are putting the gears into a specially designed case, such as
one for ALMS or such. The minor reduction in power output (Helical gears ARE
95% efficient) doesn't necessarily outweigh the potential life issues (you
can't win if you don't finish). Most Spridget racers (SCCA and Vintage) are
restricted to using the factory tranny case, so the weight issue is NA.
In reply to Bob Walker's statement about more favorable ratios- If you're that
serious, gears can be hobbed to any ratio, I've done it-how much money do you
have, how fast do you want to go? that's no reason in and of itself.

Interesting, but incomplete. If you connect the dots, you quickly
understand that that increased thrust load also absorbs more power. Coupled
with the implied extra weight of the transmission case for the helically cut
gears, you have incentive for using a transmission with straight-cut gears.
