1iTim - Great to see the video clip of your car rolling out of the garage.

Good luck, Paul.

Well its been a while. A couple of moves, job stress lowering a little I'm planning on some more work on the car soon. Likely to do more updates in U-tube. nice to see your cars too.

Tim

Have you got a photo of your supercapacitor bank ? How long can you crank the engine on a single charge ?

i have a string of technically 83 Farrad total (6x300F/2.7V in series) but several internet electric people have got a tested 50-60 farrad output on this string.

I tested the circuit on free modeling software and it pulls about 300A from zero V, so i bought a 120a breaker that i have in series with the tiny Li battery i have. It cranks over for 3 -4 seconds taking the voltage from 13.5 down to 10. then the capacitors charge from the battery in seconds (30 or so) for another go. Since my 948 cc is still running its generator not an alternator it could still be hand cranked, so i think the power is adequate. I've just stuffed something up and it wont spark at the moment. I only have videos and have not yet posted the unsuccessful cranking vid. the rapid charge from low voltage is also taxing the capacitors over-voltage circuitry and i may have difficulty there. (i also anticipate problems running at night)

The best bit is that the caps and Li battery weigh in at less than a kilo.

Tim - Whilst you appear to have less room to work in than I had, at least you’ve got a roof!



Hope ‘life’ settles down and you get to spend a bit more time on the car.

Good luck, Paul.

Hi Tim,

Can I just check please, you are using 300 lb springs? Are they going to be a bit stiff considering the car will be much lighter than Herald?

Thank you.

Ditto the above. I started with Vitesse 230lb front springs (car weighed 680kg with straight six up front) and couldn't go above 50mph without the front wheels bouncing off the road surface. A switch to Spitfire 180lb springs on Gaz ride/height adjustable shocks set to the second softest 'click' resulted in the front wheels staying in contact with the road and made for a much faster car in the real world.

330lb springs might give you an edge on the race track, but they might just leave you in a hedge on the road...
