Is this a follow up to your post in the drag section on best organic clutch? If it's a serious drag application, follow Hurst390's recommendation to get a slipper-type race clutch. If you like McLeod, look at their Soft-Lok kit.
The twin organic clutches are fine for street, autocross and occasional drag (if you don't power shift) if you're at the power level of needing one and don't want the chatter or harshness of some of the single disc non-organic clutches. I'm running an original Street Twin which included a custom drilled flywheel with mounts and standoffs for the floater plate and pressure plate. It has twin 10.5" organic discs and I went with the aluminum flywheel (faster revs, less shock) and their hybrid borg&beck long PP for more consistent higher rpm shifts. The discs have a marcel carrier but solid hub, so limited ability to absorb shock or harmonics. It revs quick, doesn't slip, pedal effort is good, but it's too much clutch for serious strip use. Expect would break things with slicks and power shifting (there is such a thing as too much clutch). The advantage of the RST or RXT Street Twins is they work with a standard flywheel and they offer different disc diameters to better match your power level. Most kits come with a diaphragm PP, but could likely custom order with a different PP if wanted. Hope this helps, RD.

We have a 1969 AMX we are not tubbing it . We are replacing the rear end Chrysler eight in three-quarter inch basic rollbar T10 transmission 401 10.8 comp pump gas . In my pick up we have ran ceramic and iron clutches complete waste of money .
Was hoping for a strong single disc organic but our horsepower probably will not allow that. At sea level we should be at least 600 horse and a 200 2 phase nitrous. Spoke to salesman at McLeod he told me the RST will shift at 8000 RPM . Hard to say but the guy probably drives a Honda accord lol The car will mostly be on the street picking on fords Chevys and whatever else wants to play. Thanks for the information. |

The hybred borg&beck. Is that lighter then a diaphragm or more holding pressure?

Benefits of a Long style with smoother engagement, adjustable pressures and centrifugal but in a smaller B&B package that is easier to fit. |

Have been out of the hot Rod seen for sometime! We used to just add more pressure to organics and live with the consequences! Thank you very much I'm always eager to learn about this new technology !!
Class guy do you use a twin clutch organic ? Or do you have a suggestion for a single clutch ! Thanks everyone Godspeed |

I have run all combinations of stuff, but I don't claim to be an expert. I can tell you what I have used that worked though, if that helps. What is the intended purpose? Street-strip is the hardest to spec. Dual disc setups work well because you can get the holding power of the extra friction surface without having to use so much pressure.

I like the idea of being able to adjust the pressure that way you're not stuck with a diaphragm! If you do end up taking the clutch out you may be able to replace the disk and keep the pressure plate maybe turn it up a little.
Rd: how heavy is the car that you are running this Street twin ? I am thinking my week link will be the T10 ! RST or street twin Hummmm? Thanks Godspeed |

The McLeod Soft-Loc is not recommended for the street.
A McLeod diaphragm single disc pressure plate static rating is 2400 lbs. The McLeod Twin disc RST and RXT pressure plate static rating is 1900 lbs. RST = street tires only 800HP RXT = street tires and drag radials 1000HP RXT-HD = street tires and drag radials 1200HP (this is a new clutch) The RST and RXT twin discs 9-9/16" will out shift the "original street twin disc" 10.5" due to the smaller diameter discs. The Twin disc clutches are great for troubled knees, that most are experiencing in our mature years! |

This is a street tire only clutch. This twin is a street and drag radial tire clutch: http://www.mcleodracing.com/index.php/rxt-clutch-pns-30671.html |
