I think the setup is, when you're cruising along it is just like your usual alternator (except sapping a little less power), then when you lift your foot off it is as if your engine got bigger and has more engine braking except it's feeding power to the battery, and then when you step hard on the gas the car feeds power to the motor to give you a boost. Basically you get a lot more low end torque for the price of some extra electronics and a second battery. Actually, you could significantly downsize the first battery and just have it trickle charged by the bigger battery when the car is sitting in the driveway, so this potentially can be done for a few hundred bucks and adds maybe 20 pounds.

You have enough room in the Spyder?

Start here, worry about mmc rods later.
