Maddness

40.160 probably.

5th chassis sounds a lil better, more room.

Interesting project, Darren. No problem to make the motor mount, either. Just send me a file/drawing of wht you need.
If you want to get to this speed record, get to it - I recently built a 40 cell electric maxx type for a german Vendor with a direct drive center diff(8 spider) and a 3/8" thick motor mount for a "22" series motor(they too hope to get speeds bordering on INSANE), though keeping these beasts on the ground above 60 or so will be pretty tricky! The truck I built was designed and geared for speed - every 500 rpms yields 1 mph, not accounting for tire ballooning(using a 15t pinion - larger pinion would yield yet more speed). Batteries will be the biggest factor for these heavy beasts(the one I built was LARGE - the customer wanted a MONSTER so it has a 16.5" wheelbase and 7+" tall tires).
