I also ran gear diff last night 100K front - 20K rear. Short right sweeper onto the straight, had to go easy on throttle as the front diff unloaded a couple of times on power, felt weird. Hmmmmm??

I really have no interest in running a diff in the front many reasons but that being one of them.

A spool is fastest with the best brakes on rubber tires, and I dont see that changing. Plus the top spool is super super light. Which is a big bonus.

according to laptimes front gear diff was 3/4 of a second faster per lap. total of 2 laps faster in 6 minutes. Havent tested on asphalt yet.

I ran over 10 battery packs , plus the front diff gave me alot more steering going in to the corner both on and off power absolutley no push what so ever with brakes just as good as the front spool. Next week is a 39t front pulley with the gear diff

I ran two gear diffs in another manufacturers chassis this week at the Nats .. It was ok when the track was dirty, and soon became lazy on direction changes , and would unload causing me to yank them both out when the traction came up.

Off power steering was awesome and hardly any push coming out of the corner.it was like a oneway but with alot of brakes

The car came out of the corner very hard. my lap times were about 3/4 of a second faster than the previous week when I was running a front spool.
What turn motor was this with?

Well done guys.

Congratulations Martin. Now you can get back to kicking all our asses in 13.5 at the Home Depot. Although the next time you decide to destroy everyone while running Jaco blues, please lie and tell me they are SJRs instead, so I won't feel quite as embarrased about running 1.5-2 seconds slower than you. thanks
