Well i'm still here! Ran the motorbike with the motors in parallel today up to 250 battery amps. Held the front brake and cracked the throttle. Back wheel broke traction then the front wheel lost grip and I went sliding the length of the shed , impacted the 100kg tig welder and shoved it through the back wall! Gotta love twin motors I reckon I could tow a car with this thing!

I'll pit either against my 10.5" Nissan forklift motor!

I wish we had video of JackBauer sliding across his shed!

Had an "interesting" experience today. Ran an errand this morning to a local hardware shop and on the way back I had to wait for a gap in traffic to make a right turn. The turn is about 100 yards out from some bad bends and has a 30mph speed limit. So i'm sitting there in 3rd gear waiting for a gap. Looked in the rearview and see a white freezer truck round the bend at warp speed and the driver has dropped something in the cab and is not looking at the road

I rammed the accelerator to the floor (and I do mean RAMMED!) and leaned on the horn. One back tyre broke traction briefly and the car launched forward. Truck kept getting bigger and bigger in the rearview then when I was bracing for the impact we pulled apart. I reckon I did 0-40mph in about 3 seconds!! Got back to work and we plugged in laptop into the bmv600. It had caught a peak current of 541Amps.

The funny thing is that Adam had asked me to do this several times and I never did as i figured I'd break something!

Thanks for that empirical data Damien!
Exactly what I needed to solidify my decision to go with a PowerGlide tranny!
