80ms shift time, and capable of handling atleast 700nm on the stock clutches, 900+ with upgraded clutches. if this works. i bet the transmission will outlive any other part in my drivetrain
Subscribed. I've removed a few of these to reseal that damn side pan and replace the mechatronics o-ring. Good trans though. As far as automatics go at least
So excited for this. I’m thinking this might make its way behind a turbo FE3 in my car after you sort out the control box. You think this will handle a 24hr race?
mine will be used mostly for street use, with some trackday use with sessions around 15-20 minutes so i hope i will be ok with a decent oil cooler for the gearbox.
a really hot summer day here is 30c.. or just under 90F. tuned BMW M4's under and m4 gts has no problems in our conditions and those cars are 500kg heavier.
custom electronics to control it. and yes, it will have flappy paddles
Got the driveshaft measured today, it will be made by a frient of mine. same guy that made Shifti's flex steel custom gun drilled driveshafts in another build thread
next up after that is making a drive from the engine to the transmission
As far as i understand, Shifti's axles are not your run of the mill standard parts. the type of steel needs to be just right, and the hardening process is special. but they have proven to be extremely reliable. pretty much everything else in the driveline breaks before those
That's fecking cool, I often day dreamed about retrofitting a DCT box to my RX7 when I had that.
Where you say you'll retain a clutch pedal, whats the thinking behind that?
Is that simply because you have no other mechanism to control pull away as you wont be able to use the OEM BMW control boxes or simply because you want to be able to launch/clutch kick like a manual?
a litte bit of both. it will be like driving a conventional sequential race gearbox, only that this is a DCT. with no auto function unless i program that into my ecu. so clutch to pull away, possible to clutchkick the car for fun and hooning around and clutchless up&down. will only use the clutches internal in the gearbox.
i dont know how to launch a car properly, but had the chance today to do some testing on a cold unprepped surface..
Raced a couple of other miatas, a tuned (500whp/700nm) m3, my friends 650+ whp chevy nova ls1 turbo, a 2018 bmw M5 ++ really fun, but its frustrating to see how efficient the modern cars are when going through the gears That will soon change
