I've been looking around, asking around with some vendors and generally trying to work out what I need, and of course I've now become a financial member of AEVA.
The main thing I want is bettering acceleration performance, mainly because I want to show people it can be done easily at a reasonable price, and the car will handle it well. I am keen to get E30 M3 speeds which is mid to low 7 seconds 0-100km, the stock 318is gets 9.1.
I was looking at direct drive and the typical 1K controller and Warp9 DC motor combo but after reading another thread (viewtopic.php?title=help-warp-9-sub-100 ... ive&t=4442) where Netgain recommended not running a direct drive unless racing, or running two motors I have more questions.
Does anyone run two DC motors and two controllers? Can it be (easily) done? Is it effective? With my budget, I thought about 2 x Zeva 600A controllers and two Kostov K9 motors. At about $6000 this is roughly a thousand bucks more than a single Zilla 1K LV and Warp9 (and no water cooling). I really want to do away with the gearbox because with 365000km on it I doubt it would last long.
I know that you can stick a 2k controller on a Warp9 (obviously costly) but I've also heard that is pushing the boundaries of the engine (which would be backed up by what Netgain said about two motors for direct drive).
I don't really want a White Zombie or Ian Hoopers RX7 so I'm looking for a middle ground which seems hard to find information about because most conversions I am finding are not quite what I'd call fast (10+ seconds) or way too fast (sub 5's).
Any help is appreciated.
