When we built the race evo we threw a lot of parts together and hoped for the best based on what we learned for the 1G and 2Gs. As for the drivetrain, we used completely stock parts with a off the shelf ACT pressure plate and unsprung 6-puck disc. If something broke we'd find something stronger but we've had no driveline problems at all so far.
I'm not so sure about anyone besides ACT being the leader in clutch development for the Mitsus. They have been there since the beginning and if you look at what all the fast cars are running you'll see ACT's name most often. Hell, Shep is running 8's on a single street disc.

You are true about ACT and there clutch development for the Mitsu. But, I think that there is always limitations to all of single disc technology has to offer the general public. Therefore the twin disc and triple were invented, and yes those also do have trade off too.

Since you were in a budget to purchase one (since your ACT 6 Puck and on your 4th or 5th fidanza FW took a **** in your car) and you were complaining about it you were going to get a clutch from me
Let me see, RPS or Tilton....
At least those are the two names that were running in your mind.

Don't get it wrong, I am not at war with RPS. I don't remember asking for anything other than information on your clutch and the best deal I could get. We spoke, I did some research, and checked the records. Your clutch has alot of issues with it falling apart and such, maybe you have sorted that out, but at 3k a pop I dont have time to **** around with substandard products.
I found that the tilton was the one to go with, as they have the best reliability record and are oem in porsche, factory race viper, and extensively used in the race industry. That says quite a bit. I can provide the documentation if needed.
Since I race quite a bit I started asking around and noticing what the winners were running, tilton. I couldn't find any of the racers running and winning these races with the RPS, plain fact, you can tell me if I am in error (with some evidence).
In addition, the Tilton costs quite a bit less to rebuild once the carbon wears and their method of doing it makes alot more sense in my opinion.
As for your attacks on the ACT clutches, I don't think that is fair. In the mitsubishi/DSM world they have the best product for holding power and being streetable at the same time, there is a reason most of the serious guys in the DSM community use their clutches. Fidanza provided me with a specially made flywheel when I started breaking the ones made of 6061 after 2 passes, they were very responsive to my needs, great customer service.
I am not trying to sell any of these products, I can tell it like it is from my point of view. People who are sponsored tend to be a little more reserved in their responses. I have no time for that, I tell it like I see it based on my experiences.

NOT TRUE! Been there done that on a 1453RWHP Supra that had over 80 dyno pulls that is unbelievable! Saad Saad would pull this crazy dyno pull like this...
In 4th gear rev it up around 7k and slips the crap out of it until the C/C glows orange and dumps the clutch and makes the pull. ALL of them like this!!! And takes it to the track and makes 9sec passes with the goodyears spinning all the way down the track. After the Pomona track event we had it inspected for wear and flatness. Each friction disc surfaces were only worn 2 thousands! With that measurement in mind the PRO disc certainly came through in our real world testing. Incredible, that the same technology can be applied to any RPS C/C clutches.

What has that 1453 HP supra run? This is what I am talking about, don't feed off the ignorance of some of these guys just because they aren't up to date on the drag racing news. He didn't win that even't nor did he even run close to what others were running. From what I read on that forum it seems he ditched the RPS for a tilton!!! It was also noted in same supraforums thread that he couldnt get into gear due to clutch problems. Was that yours or the tilton, take your pick.
Http://www.nhraimport.com has the results from that race.
Dyno pulls really aren't a good measure of a clutches ability to handle slippage and heat, I am sure you know that.
Like I said before, where is the proof in the racing results that these RPS clutches are so great? Surely you have more thyan just Saad. Where is your string of fast cars that win events like the ACT? What about mitsubishis that run fast with RPS (lets stick to the ones that actually complete passes here)

Limitations ??? Ask john shepherd what his limitation is.. 8.6 on a single disk.. Amazing. Im sure evom would love for you to promote your clutch on this site as a paid vendor. At the end of the day your asking someone to spend 3k dollars on a clutch system which nobody runs and isnt proven. ACT is by far an obvoius choice for many reasons. For 450 dollars and 100 a disc ... You could use 25 clutch disks to just equal the price of your one clutch. Food for thought

Winners is where I will stick on the subject. World's fastest 3000 GT VR-4's running 10s are using RPS twin disc C/C Mike M Altered Atmosphere. World's fastest 5speed no nos 300 ZX TT running 10s is using RPS twin disc C/C Zoe Specialty-Z. World's fastest 6 speed Supra running 9s is using RPS Twin Disc C/C Ryan W Wide Open Throttle Motorsports.

The rest of these cars you re talking about, I have never heard of, did they enter any competitive events this yr where we can verify what times they run?
So did Saad really drop the RPS clutch and go tilton or was that the RPS he was having shifting issues with?

I drive the Cusco carbon...and love it. Stainless line with restrictor pill in there, and it is the best mod. The t/o bearing is ridiculously loud, but hey...its a bad a$$ clutch. As far as someone said, "double clutching" while drag racing? My friend, I would research that a little bit. I think someone said it in a movie, and to be honest, it sounds incorrect.

If I had a perfect Carbon clutch that I paid $3000 for I cannot see myself removing it to put another clutch in there. So he is trying the tilton to put the RPS back? Cmon guy. Probably got sick of the issues and decided to make a change.
Anyways this is some more info for you on the Clutch situation, let me know if it is innacurate.
"Tilton has a patent on this design. AP Racing (supplier of most F1 clutches) and Quarter Master both have licenses from Tilton to legally use the floating hub design. Tilton's carbon/carbon clutch has over 17 years of development time and is one of the most widely used clutches in professional road racing. In fact, Tilton 5.5" carbon/carbon clutches are OEM on all new Porsche 996 GT3RS race cars. This is fairly respectable given the track record of these cars, and the fact the Sachs produces carbon/carbon clutches and is in Germany. The 7.25" 3-plate C/C that is used in the Supra set-up is the same clutch that Tilton supplied to Chrysler as OEM on all Dodge Viper GTS-R race cars. Both the Porsche and the Viper have won the 24hrs of Le Mans and 24hrs of Daytona on Tilton carbon/carbon clutches... the ulitimate proving ground for clutch durability. Their are more difference than you think between carbon/carbon clutches from various companies."
Nothing personal just facts.
