the MegaWatt - 1000ftlbs of torque?
Discussion
Just completing the build diary of this electric animal built in Barbados by Dan Johnson, follow the complete build here :-

Aiming to be the fastest accelerating Westfield ever, and furthermore, the fastest accelerating road legal electric car!

Yep, spot on, the MegaWatt is two-fold, it follows the convention of the Westfield naming game (MegaBlade, MegaBird, MegaBusa), also, it's only 640Kw - *for now* We can add as much as we wish as we go on.
Agreed on chasing the fault/weak point, it's going to be part of the build process. I expect the standard prop UJ into the diff to be the first to go (although we're aiming to beef that up before the first event). Driveshafts and diff will be next on the list of suspects. The beauty with the controller is you can set it to exactly how many amps you wish, 600/800/1000/all the way to 1800 so it will be a case of just ramping up the power and examining along the way, replacing/uprating as required.

Bet you turn it up to '11' on the first trip out though
Really is an interesting project though, thanks for sharing. Probably a good job you are doing it in Barbados though - can you just imagine what TPTB over here would make of it??
It is tempting! But for testing (in two weeks) on the drag rubber we will have to approach it 10-20% at a time... Really is an interesting project though, thanks for sharing. Probably a good job you are doing it in Barbados though - can you just imagine what TPTB over here would make of it??

Awesome reading, we got room for one more up front if we need it It's not a hybrid, it's pure electric - twin series wound DC motors.
The initial 'drag' battery pack is 384 lithium cell batteries, 640kw power (64 batteries in total). That'll be used for drag as it's high output/discharge but subsequently low range. The car will end up with a larger battery pack for cruising.

First event down. Only got to do 3 runs on the 1/8th of a mile with every run chopping time off as we sought to dial in tyre pressures and shock settings.
Final time on the strip was 6.626s. The strip here is unprepped, so anywhere from 0.4-0.7s slower than somewhere like Santa Pod. The car smashed the 2WD record and missed out on the overall car record by just 0.03s - one more run and it would have had it!

Hopefully have another timed test in a few weeks time to get down deep into the 6s and make the decision as to whether to push to 12" slicks on the back. The car was wheelspinning 2/3rds of the way down the strip!
