Those options would ALL result in REDUCED performanceLong time member here, I remember back when Mate Rimac was just one of us and not an EV Supercar CEO.
I always have and still want to work on a DIY EV project but was taken by the performance and value of the model 3 performance, so i bought one.
However I would like to get this community's opinions, advice and guidance on increasing the performance of the P3D.
I had a few ideas and once you deem me crazy I would be interested to hear new ideas from you all.
(1) install an independently powered and controlled 3rd motor (Tesla model s front motor) on to a 5th wheel that would make contact to the road under/within the rear trunk.
(2) install an independently powered and controlled 3rd motor (Tesla model s front motor) to the rear of the model 3 and connect the inner cv axles of the oem rear motor and 3rd motor with a belt or chain, on both sides of course, to couple the oem rear motor and 3rd motor together.
(3) install hub motors at the output of the tesla oem motor gearbox and get custom shorter cv shafts made.
I do realize that all the options represent a lot of work and would require material amounts of customization, i guess i am wondering if they are even possible from an engineering and reliability perspective.
Is there another more obvious option I am missing?
The main limiting factor is the ability of the tyre/road interface to transmit power to the ground and those options all make that WORSE
I would suggest instead
(1) Reduce weight - there is a lot of luxury in a model 3 - all of which can go
(2) Improve suspension/brakes
(3) This is the expensive one - you need to "hack" the software and increase the power
The Tesla is operating on a compromise because it expects 200,000 miles with no failures
If you are willing to accept a greater chance of failure (which is what "tuning is all about" THEN you should be able to stretch the power a good bit
