But now Motor Sport Australia is having a hissy fit about EVs so I can't use one there. That surprises me. I would have thought they would have been all over EV's with the current mentality of the world.  What is their objection to them?   Quote   I am targeting March 2023 to have it on the road. What sort of batteries and capacity and Motor output are you looking at? Will this not be expensive to have certified and are you limited in conditions on rego or anything? Be interesting to follow your Project. Thanks The objections from Motorsport Australia are vague and unstructured. They tried to claim that I needed to go through some fictitious extra EV process to have them allocate a class. But that is BS because the event was a regularity where there are no classes. So they were just running scared. They just latched on to any excuse to kick me out. They wouldn't even give a refund for my entry. I had been competing in EVs under them for more than 4 years before they even realised. There was no written rules. I interpret all this as just being scared and ignorant. They wouldn't even talk about it. I still hear of other EVs occasionally competing but they are only getting away with it because Motor Sport Australia don't hear about it......RANT OVER....for now I am in two minds regarding power. I have already re-purposed my 8 inch DC motor for this project. My first option (fall back position) is to re-use my existing controller with a new battery. It would run at 172v and 1000amps. It realistically provides about 90-100KW. This would give me exactly the same performance as my previous car. That performance was great up to 80kph but mediocre after that. So my latest thinking is to upgrade the batteries and controller to achieve slightly higher voltage to improve the performance between 80 and 120. I'm not sure what voltage the motor will handle so that would require some testing before I could quote any specifics. The car is only 550KG assuming I stick to the original option so it will be awesome to drive. I originally hoped to make it AWD and based off a Locost chassis design. But my engineer talked me out of that direction because of the engineering costs. He recommended the current chassis because it is a known quantity. He has already certified many of these before. So long as I don't alter the chassis it should just need some inspections. That direction reduced the engineering costs by many thousands. It will be fully registered with no restrictions.   Oh and I forgot to add the link to my full set of progress pics: https://flic.kr/ps/3W7voH Edited 2021-09-17 14:57 by galderdi
