Hey, nice to see another Spitfire conversion. There's nearly a dozen in the 'Garage'. I converted a 1979 Spitfire Build thread is here Unfortunately these forums 'lost' most of my build pictures..
While I was doing mine, Moltenmetal converted his 1975 Spitfire Build thread here
I've been up to 85mph in mine (in 5th gear). I haven't timed 0 to 60, but I'm sure I'm not under 8seconds. I used a Warp9 DC motor -- which has a lot of torque.
With your performance goals, you will need a transmission. Going transmission-less would definitely not get your 8s 0-60mph goal, and might not get you to 80mph either. I needed the overdrive gear for that, but the AC motors do have higher RPM ratings than my DC motor -- which is whey I say 'might'.
I would highly recommend not to use the original transmission. It can't handle the torque of the electric motor. I've seen a couple of conversions where the original tranny didn't survive long. I used a T5/World Class transmission in mine. Moltenmetal had a Toyota transmission.
The Tesla cells are certainly a good choice for weight to performance. They weren't readily available when I did my conversion.
I'm looking forward to seeing your conversion progress!
