adjustable valve for clutch for launching?
 

I'm wondering if I can install an adjustable valve on the clutch hydraulic line so I can dump the clutch and have it engage a bit more slowly?

I figure it won't affect my pushing the clutch in, but when I launch, when I dump the clutch hard, it will engage the clutch a little more slowly and smoothly.

Trying to save my axles.

don't dump?


what you're describing is possible by the actuation of your left and right foot...

you can also just get new axles...

Thanks for the info, but I already know those two things.

I was hoping to get an answer to my question.

I want to be able to release the clutch quickly and have it engage consistently and smoothly, and I'd like to be able to try and dial that in.

I know a lot of cars have something similar in stock form.

I would think this would let me launch safely from a stop without shocking my axles. Im exploring options before buying beefy axles.

Go look around on BMW forums regarding CDV (clutch delay valve). Great idea in theory, in practice not so much.

I installed a needle valve on my Minibusa so I could floor the gas peddle, side step the clutch, and it wold take a half a second to bleed down giving me a nice smooth launch. But this would also effect every gear change which may not work for you. I have a sequential gear box with full paddle shift on the Minibusa so once I got rolling I no longer used the clutch.

Thanks! My old BMW 135i had one of those valves.

I'm wondering if there's an adjustable needle valve or something I can install that would let me adjust the speed of the actuation.

I don't want to sidestep the clutch, just set my launch control to a certain RPM, then be able to dump the clutch and get a smooth launch without breaking axles.

I'm at around 300whp/225torque with big tires (PSS 265's) and I'm spinning them in 1st and 2nd.

I know better axles is better, but I don't plan on drag racing that much, if I could install an adjustable valve and launch consistently, then I'd try that first.

That's exactly what I'm looking for.

Good point about it affecting every gear, I hadn't thought about that.

In my head, it might still work, because the settings would be just a little slower than of a full dump.

Where did you find the needle valve?
