Re: IPace Front Motor Hacking
I know there have been a lot of other projects on the go so the big cat project has been on the back burner. In the last video there looked like good progress on the inverter reverse engineering and the next step might have been some test drop in boards. Wanted to check if there were any test board...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
I read about this 1.2million mile model S the other day - which shockingly has had 13 replacement motors! Seems even Tesla couldn't fix it! Would be interesting to know what kept failing on these - if it was the same coolant ingress problem? https://insideevs.com/news/699413/highest-mileage-tesla-mo...

This makes it easier to fit into linear space. But as for reliability is concerned genuine Audi coolant pump is the toughest Th...

Re: Radiator Core Size...cooling capacity?
I've heard this a bunch from normal car guys, and the logic has never made sense to me. Coolant can't flow "too quickly to cool" through the radiator. The radiator is removing a certain amount of heat per second. It does that regardless of how fast you're pumping the coolant through it. I...

Re: Rear diff ratios with GS450h
For those running a GS450h transmission, what are your rear differential ratios? Mine is 2.73 and I'm thinking of something in the high 3's to get more low speed torque. I would work out your motor rpms at your maximum vehicle speed - then work back to see if you have headroom to increase the diff ...

Re: Starting a project. Help choosing a motor path....

Just pick the option which you would find easier - and which is move available/common in your country. I ...

Re: Audi A2 /w Prius Gen2 Transaxle & Inverter [FINISHED]
I'm not writing it off even with just MG2. Of course 28 kW isn't very performant but as a small commuter car it'll do. Heck, people used to drive around with 15 hp. Also the motor is barely heating up, so we're not pushing it here. On a side note I'll do a first TÜV visit on Wednesday. From this si...

Re: Lotus Elite + GS450H
Yeah, gearing would be a problem alright. I'd need a tall diff ratio, there is 2.88:1 available that would solve the issue, but more work and cost. I'd still go the 300h route if I can get the power output confirmed as it will be a better finished package at the end of the day. As long as it can pr...

Re: Damien takes Zombie GS450h on dyno
I guess its one of those tests that for me actually opens up more questions... The current limit on Damiens car is 500A from memory. 500A and 350v is thereabouts 175kw or 235hp. So that matches up fairly well with what he measures. The time it takes to get to peak power would be a concern for me. A...
