WOT Shifting? - The Unofficial BMW M5 Messageboard (m5board.com)

So reading through another thread, it was mentioned Wide Open Throttle (WOT) Shifting. Have you tried this? Those that do it, do you do it often and how does it treat the stock weak clutch or aftermarket?

The M5 clutch cannot handle this, it will slip on WOT shifts.

Do you mean flat-shifting? ie, keeping the throttle pinned while clutching, shifting and de-clutching?
If so, then I do not believe in flat-shifting a car that has not been designed to handle it.
In my book that's called abuse.
If the system has been designed to cope with it either by mechanical means, or (more commonly these days) by electronics effectively lifting for you, then fine: you are within the machines design envelope.
Otherwise to me it is a false economy because you while might get to the end of the front straight quicker (by a poofteenth only) but you will likely not reach the end of the race.
Just my HO.

Ok, so thinking out loud, while you are shifting, the throttle will hit the rev limiter while shifting. Well maybe not, unless you are slow, right?

I've only done that type shifting with my old, beat clutch. I have not done it yet with the new clutch. Cost to much $$$$$ to beat it up like that. IMO

I shift at 6500 all the time and I don't get any slippage. I don't launch, but my clutch handles well under the conditions. I bought the car in dec so I really don't know if its he stock clutch or not, but it does its job.
