Just curious, do you double clutch when dragging?

 

The differences have already been noted if you are looking for a carbon setup on why RPS is superior to all of them. RPS is the ONLY one that uses carbon inserts on the flywheel, floater, and pressure plate unlike the Exedy, ATS, etc therefore it will not warp and it will not have hotspots. If you are considering a carbon clutch then I don't think you can look other than RPS right now. ATS now offers a CCM(carbon coated metal option) on their clutches now but it is a additional $50. Not to mention the disk cost $600 bucks each and it does not have a warranty. RPS has 180 day warranty and rebuild cost is only $400 bucks.

I'm very curious to see how the ACT with 6 puck solid hub would work on a street driven high hp car that is frequently drag raced. I think you guys can agree that no DSMer had luck with that setup.

If you are double clutching while drag racing there is something wrong.

Fas4doors exedy twin cerametallic is slipping after only like 2-3 months. It slips on a hard launch and will slip the rest of the way down the track. If it is launch soft it will not slip. This car is also dragraced VERY frequently.

 

Hi Mark & Jeff,
I would like to know one thing, is the ACT 6 puck any smoother than the 3k clutch that you are talking about? RPS has always been the clutch leader in smooth engagement and having the patented technology to provide the very best clutch money can buy. Innovators are always looking to be on top of the game. I'm with RPS cause we cover all of the bases and more!

 

 

BTW I really hate to push something and have somebody think I'm just trying to sell them the high dollar item or something. This is not the case. I sell all of these clutches so whichever one you want is fine by me. I will get you the parts you want for the best price no problem. I only stress it because everything that I have seen and got calls about in other clutches have been covered by RPS. Therefore that is why I try to push the RPS a little bit more.

 

my question is.......

is it true that you have to heat up the clutch before you launch?

cause i heard through the grapevine that you have to sit on the clutch at 2-3k and slip it to heat it up or else it won't grab under heavy load......

 

That is not correct. It will grab. However it is true that many will heat up the clutch because that way you get the most consistent launches. JT will explain further.

 

Go with the RPS twin plate carbon its a little steep in price but it has 6 month warranty including racing and after 6 months if it does fail you can rebuild the whole clutch for 400$ PM me if you want a price

Thanks

Well, we need someone with it in an Evo to break it down for everyone... Compared to stock, what is the difference in:

Pedal effort?

Pedal travel?

Engagement time and feel?

Noise while engaging?

Noise/clatter at the stop light in neutral?

Expected longevity for the street car?

Expected longevity for the weekend warrior?

Never have I been so interested in something I absolutely and utterly do not need... that's the manufacturing tech junky in me I guess.

 

agree someone needs it install in there evo.so if rps or anyone wanna give me one for free i'll be the tester

 

Do you have any personal experience with the RPS cutch besides what you've read? Do you have one in your car? Have you driven or raced with one?
For $3,000 why not just get a Tilton clutch that has been proven to work?

 

Tilton is a lot more than 3k. Plus you have to have a custom flywheel made. I don't have one. The ones we sold are shipping this week so we will have customer feedback for you guys very shortly.

Also this info is not what I have read. I have talked to RPS about this since they where making it and know all the details about it. We also work with them with supra clutches and other carbon carbon applications built by them that have never given us problems.

 

LOL, I can give you a free C/C T-shirt.

The rumor on heating the C/C clutch to raise the co-efficient of friction is true for both RPS and Tilton. For a C/C Tilton 7 1/4" the largest size available from them, the clutch will support a high HP car but will be slipped to raise the co-efficient of friction and will change the torque capacity. Slipping a Tilton to raise the co-efficient of friction will result in to an on/off switch engagement (especially when the whole assembly weights less than 16lbs. As for RPS's 10" C/C dimension clutch and the PP clamp load being only at (2100~2200) we have the capacity to go higher in clamp load if it's necessary if it slips too much. The technology is supporting other cars making more torque and using the same pressure clamp load. Supporting street car that make 40lbs of boost two stepping and not a hint of the clutch letting go!
