I'm interested to see if anybody has used one of the 3 Street twins out there?

RST - organic disc / diaphragm press plate / 800hp rating
RXT - ceramic disc / diaphragm press plate /1000hp rating
Original - organic disc / B&B long press plate /1200hp rating

Any feedback from users out there?
Likes / dislikes?

Not sure which one I am using, but I do have a street twin in my car. Clutch action isn't too heavy, but there is no real slipping to engage or disengage. Its almost like an on/off clutch. So be sure to have the revs a little higher when starting.

Thanks for the reply.

How long ago did you get yours? I think the RST / RXT style just came out a few years ago....maybe less. The original one has been out for a bunch of years.

Did yours come with the flywheel? The orginal style ones, came with the flywheel that is sculpted out. The RST / RXT ones don't come with a wheel, and you can use your original / aftermarket flywheel.

The RST / RXT versions are supplied with a 1500lbs static weight diaphragm PP which translates (at 60:1 ratio) to about 25 lbs to push it in....VERY VERY LIGHT.

A "normal" pressure plate in the 2400lbs range would require about 40 lbs to push in.

Do you POWER shift that clutch? Can you keep the foot on the gas the whole time and just stab the clutch pedal to shift?

I had one in my 'cuda 535 hp and hemi trans..wouldn't go any other way. Shifted flawlessly, light pedal, good feel, never slipped. They last a long,long time...

kbcuda,
Which setup did you have? RST/RXT/Original?

What about speed shifting? Were you able to shift by stabbing the clutch pedal and not lifting off the gas?

Details, details, details

Why the higher revs? Chatter?

I put one in a customers 499/750hp B body...he was doing 2nd gear burnouts (no brake pedal) just dump the clutch...drove right through it.Don't know what version it was I just put it in.
He has a 20 puck sprung hub disk/ford long style (1800 lb) in it now ...no driving through that.

I have the original B&B long in the tt340 Chally. Since this is a street driver, I went with one solid disc and one with marcel to combat chatter and make it a bit smoother engaging.

It is an absolutely awesome setup. Very light pedal, totally smooth, complete disengagement. If you shift it hard and fast it hits dead hard with no slip at all. I would never use anything else on a high hp setup.

At least with the B&B, you have to have everything just right. Flywheel runout, bell housing face and bore all have to be dead nuts, or you could be fighting chatter.

Installed it back in 2001. I keep the revs up because it grabs so fast, I have stalled my car. I haven't been too brutal on it, but I don't baby it either. Has held up fine. When I spoke with the guy at McLeod he said that it would be the last clutch I buy. I bought the whole assembly: flywheel, discs and pressure plate. McLeod gave me part numbers, but I ordered it through Summit for substantial savings.

I've been running a twin disc for a year and a half, I love it. Lite pedal, no slipping. Just a word of warming, it will take a little getting used to, as soon as you let up on the clutch pedal, it is grabbing and it means business. Plan to keep the R's up a little and be preparded for a little tire spin at stop signs. I put a RAM clutch in first, it lasted one night on street tires, then a Center Force, it lasted two weeks on street tires, finally I went with the McLoed duel disk, life is good and even better with sticky tires.

I think that those of you that have the very quick engagement issues might want to have one of your discs relined with marcel added. It will cushion the engagement and allow smoother starts without high rpms being needed. I can let mine out at idle and it will move without issue or excessive grab.

I had the original type street twin years ago and it had a marcel in one of the disc out of the box. I agree that a steet twin will last forever but if you dead hook it with slicks you are going to break stuff.

Yep. Now have a Dana 60 and Denny's drive shaft. I have only run BF Goodrich street slicks so far as the stickiest tire. The street tires are normal fare for the car.

Sorry to hi-jack, but is it correct that using these twin disc clutches requires that the large return spring in the pedal box be removed?

So it looks like everybody on here that has one, has the original B&B style. Great info. I was curious about the power shifting and slow disengagement. I guess that's not much, if any, concern.

I'm looking at the cheaper RST version, which comes with a Diaphragm PP and organic lined discs.

Anybody use this setup yet?

Larry,

My only reservation about them is (I imagine because of the rotating inertia) they are (from my experience) a bit slow to react, with Either a quick shift or a long throw the PP reaction/reengagement isn't quite as quick.....part of the reason I'm looking for a 3 gears (2 shifts) in the quarter for my own car is that I will probably wind up with a twin in my car as well. I'm a little leary of Diagragm clutches except in close ratio apps or really light cars (my 427 Cobra has a diapragm and it works great), they don't always do as well (react fast enough) with wider gear spreads on high powered cars, not without some custom tweaking of the CW's
