Can you fit the HyPer 9 into the transmission tunnel, where the transmission is now, without structural modification? If you can, the gain of space in the original engine location for battery modules would be a significant advantage; however, if it doesn't fit there and has to be forward of the firewall then saving some weight would be the only benefit and you will be limited in torque to the wheels by not being able to use a lower gear.Drivetrain: My biggest question right now is whether or not to use the stock tranny. I really like the idea of direct drive and the advertised Hyper9 specs seem to suggest it would work (as well as several threads on here). Is this reasonable or should just run the stock tranny for the near future?
At this time, I think you'll be lucky to find anyone who has even completed a HyPer 9 build, let alone one without a transmission and in a car of comparable size to the Spitfire for a useful comparison.For those that have done direct drive with the Hyper9, how is performance?
