Which clutch? posted by 00Evan on January 25, 2005 at 07:58 AM

Depending on your budget and how much you race the RPS Max 6 puck is the way to go for most people....... RPS is always testing and using the latest materials and designs in their products. The material and the spring design in the hubs has come a long way over the years. The spring design to handle the abuse of drag racing was perfected a couple years ago and no problems with springs in units built over the last couple years have been reported. The latest friction materials RPS has been using in the past year for 6 pucks are nothing less then amazing in smoothness and durability. For occasional racing and mostly street driving the RPS Max 6 puck is going to be the most cost effective clutch to handle the job. We have had many, many of our customers have great luck with the RPS MAX 6 puck for drag racing. Most of our local guys have run 1.6 sixty foot times with this clutch and a few have hit 1.5 60 foot times. An aggressive Disc is like a sticky tire......It is going to hold better but it will wear faster when you push it. With a single disc and trying to get a 3600 lb car moving from a dead stop up to the flywheel speed of 6000 to 7000 RPM will wear a single disc if done on a regular bases. With that in mind the materials will take an amazing amount of abuse and last a reasonable amount of time for what you are putting them through. The great thing about the 6 puck material that RPS is using is I have never seen any one glaze the material. Street Disc's are made for just what the word implies (THE STREET) If you use a street Disc for Drag racing with a sticky tire, The street Disc will be the weakest link in the chain and it will glaze, Once the street Disc is glazed it will no longer hold the same power. For those that our serious about racing the best is the RPS Carbon Carbon twin Disc...... With more friction surface area you do not need as much clamp load to hold the same power......This allows the pressure to be less on the pressure plate and has a much softer pedal feel. The Carbon material is extremely smooth and allows for stock like engagement. The carbon material also works the opposite of regular friction material where the hotter it gets the more power it will hold. Most regular friction materials will fade as they get hotter. We have seen Carbon Carbon clutches with over 200 passes on them taken apart and measured with almost no measurable wear. If anyone has seen videos of ZO racing his car, You can see the abuse that the Carbon Carbon can take. Member WXY was one of the fastest stock turbo cars last year running 11.61 in the 1/4 with a 1.59 60 foot. He drives as aggressively as Zo and uses the Max 6 Puck and has hit 1.55 60 foot times. He is extremely consistent and 1.6 60 foots are normally his average 60 foots. Member SirpriZ that has put the diff gears together has been running 1.6 60 foots for the last couple years with the Max 6 puck. Mike (LA Canada) has also been running the Max 6 puck and hitting 1.6 60 foot times the past few years. Plenty of other locals as well, But this is getting long and I think you have the idea :)
