Shifting

dsimoes1 · 10-13-2012, 07:01 PM

Alright so I know this is a pathetic question but what's the proper way to shift in high rpms. For a manuel car. Anytime I do it I have to let the clutch out slowly or it makes a very ruff start every shift. I also let the gas off completely. Is this right? Remember this is for high rpm/ racing

these cars suck for shifting.... i learned that if you give it just a touch of gas it makes it much smoother, and the other night i was reading that it is really jerky when you let the clutch out in high rpms because there is some sort of regulation valve in the hydraulic clutch line. this makes it impossible to just dump the clutch, they make a part to eliminate the valve, but it states that you can do with out the part and just crimp the two lines together, but may result in a clinging sound

Do you know the name of the part? Or a link? I want to buy it now

Upshifting from one gear to another 101:

1. Let off gas
2. Disengage (push in) clutch
3. Move gear selector up a gear e.g. 3 > 4
4. Engage (let out) clutch
5. Get back on the gas

Driving a standard transmission car is summed up in one word: timing. You won't have smooth shifts if the shift is mistimed e.g. you engaged the clutch too late, engaged the clutch too fast and so on. You'll inherently 'learn' this via muscle memory, so don't expect to be a smooth driver overnight. The steps above overlap each other to an extent - that extent is the timing you need to learn.

This is a good thread to peruse:

Lots of people sell these modified valves, here's a link to one off the top of my head, but in my last two cars (E90 and E82) I just took the valve out and connected the two parts of the hose together and it worked like a charm. My 335is has DCT so I obviously don't need to get rid of the clutch delay valve but I consider it an absolute necessity on any manual BMW. If you're comfortable with a screwdriver, you can just get rid of your valve yourself but you could always have a shop do it for you if you prefer.
