Heaps of room. The green line is where the bottom of the headlight will sit

I removed the front bumper and fender lining, and 3d scanned them. The brown is the bumper cover, the messy bits are where the fog light normally goes and will be the main air intake with some cleaning up. Blue is the fender liner, the green panel is a cover the hangs of the chassis up top...

I saw some Marine ones that are 48v, but they are also NZD$5000

It occurred to me that we are using the wrong tool, instead of a few alternators, steal from hybrid cars and their generators. Designed to work in an engine bay, so can take the heat and vibrations. They call them belt starter generators, as they can also be used in place of the starter motor...

I don't know if alternators alone would cut it, and then you have the parasitic draw of the alternators, if your alternator is taking 25hp to drive to give you 350 amps to power your electric motors I think all that is doing is adding complexity and more things that can fail. And you will...

Do you need boost full time, and what is full time, is it a 20-minute track day session or a 3-hour drive through traffic? If you need it available full-time but not on all the time then think about a second alternator just for charging the boost batteries. I haven't finalised my design setup...

These guys have gone silent on me, https://hakadibattery.com/ after I asked for pricing to ship to New Zealand

Thanks, that would be cool

cool, got a link to the store? I am planning to go with LTO batteries and have seen reviews calling small den a scam store, but they seem to be the most pushed on aliexpress

Hi, It is time for me to buy some batteries, and dropping a ton of money on Ali Express makes me nervous. I am in New Zealand so have limited options. One site I have looked at is https://hakadibattery.com/ Does anyone have any experience with them or maybe some alternative stores to...

nice car, interesting and rare

Mine is almost silent buy I can barely spin it, its quite stiff and stops spinning after at most a quarter of a second

I think the big limiter will always be the batteries, you cant run one off the normal car battery and alternator

time flies bro

Same, the electrical side will be the biggest challenge for me. Lots of reading to do

yea, I had tried to get the manufacturer of the P2 to provide one, but I tried several methods of communication with nothing but silence from them. I know nothing about compressor design, but I suspect the even if the volute interior is the same and of the same quality of finish that the...

has anyone seen a map for the P2?

yea, so I am thinking a dual motor setup to drive the compressor, high rpm and stepping it down through the belt drive. Maybe have the motors drive a shaft that is 1:1 with the compressor and drives the belt, gear the motors to the shaft, flip the motors 180 deg to the other and have each motor...

I did some digging, and asked a couple of AI bots, chatgpt and googles gemini, they seem to agree that turning the compressor at 35,000rpm, a PR of 1.5, 65% efficiency and 65ish pounds of air will take 37 to 40 kilowatt's of power (50+ hp) Does that sound right to you guys?

You ask tricky questions :) My next step is learn all I can about batteries and motors. I have been unable to get a response from the manufacturer regarding a compressor map so my default gearing/pully sizes is going to be a guess followed by some trial and error. Also I am not liking how only...
