Diaphragm vs. Borg and Beck.............

Yep. The birth control guys get butt hurt easy.

Oh look, he started in with the name calling. Again. I'm not offended, you're simply just wrong in this case. All I did was point that out. I simply said, several times, that what you're suggesting is totally unnecessary. Ok, I called it lunacy. But spending $2k on a clutch for a 200 hp car is lunacy. Your set up probably works great for a 9 second drag car. Your incredible knowledge of clutch tuning may even allow you to run it with ease on the street, even if I think you're stretching the truth on that since you're so unwilling to explain how it is you actually manage that. Regardless, there's no reason to use one in this instance. None. And you've given no evidence or proof to show otherwise, just the usual ill will and name calling.

If you were truly an expert you would know that recommending a $2k clutch when a $300 one will do is in fact lunacy. No different than recommending a $300 clutch when a $2k clutch is needed, it shows the same lack of knowledge. Clutch tuning is a great skill to have, but unfortunately 90% of the people on this board have absolutely no need for it whatsoever because they can run off the shelf "junk" that will last the life of their cars trouble free without having to do any tuning at all. Anything more is just a waste of money and time for a vast majority of cases.

Hey yellow rose-
how do you go about tuning your clutch, do you use a data logger?

Good luck. Many people, myself included, have legitimately asked yellow rose to explain his process and set up in multiple other threads, so that they might actually try and learn from his supposed immense knowledge. He's never explained, he typically gets defensive like he has here already and basically just keeps saying that if the rest of us knew what he knows we'd all run the same thing as him. Of course, he's never actually said what he runs beyond saying it has a sintered iron disk and a Long/B&B cover, so, it would be difficult to know even if someone was running the same set up as him.

Based on your wonderful explanation of modern diaphragm clutches earlier in this thread, I'd be willing to bet you have nothing to learn here, even if yellow rose is truly the expert he claims to be.
