New clutch advice
Within about 6 weeks I'll be installing a new boosted LSX427 with expectation of about 800rwhp. Currently, I was making about 680rwhp. and stock clutch started to fail, also experienced the pedal to the floor issue, and missed shifts with grinding issues.
In the market for a new clutch and of course there is McLeod RXT, SPEC Twin, RAM, ZRI (LPE, and a whole bunch of other names), problem is twin discs are better known for track, and single for street. My understanding is single will behave much better on the street and last longer, while twin discs will handle on the track better but won't last long with stop n' go daily traffic. Many vendors claim their twin disc clutches are now capable of dealing with the daily city traffic grind. I'm going to need something really strong so reaching out to C5 members to see what they went with. If you could share the following that would be great. TQ / HP = Brand / Model = Disc # (1 or 2) = Disc material (iron or other) = Satisfaction = Chatter (Y / N) = Pedal feel (stock or harder) = Engagement (low or high) = (stock clutch doesn't engage until 3/4 of the way off the floor for example). Much appreciated. |
I think twin disc clutches are easier to daily drive than a heavy duty single disc. That being said, I just ordered the McLeod RXT.

Please, let me know how you like it once you get it. |
Mainly stock right now, but I'm putting a Whipple on soon. I put the RST in my Trans Am. So far it's great. Very good manners.

McLeod RXT! FTW
Just installed mine and its super smooth and rate at more than 1000 hp no chatter super smooth twin disc softer than stock petal engagement a little lower than stock 100% satisfaction |
Single vs dual disc is one hell of a debate. I'll give you our two cents and we can go from there.
Dual discs are comprised of a flywheel - disc - floater - disc - pressure plate. The issues you run into with multi disc units are numerous. Yes, you can typically get more holding capacity out of less plate load, however, by stacking the discs you complicate things. Here's a list of pros and cons. DUAL DISC PROS -
Don't get me wrong, we've got a few test twins and triples in the market as we speak. The only reason we haven't released a twin or triple is because we're simply not done with research. Could we have had a twin in the market a couple of years ago? Sure. The difference between us and most is that we will make certain that the Monster twins and triples will drop in and go. No shims, no measuring, no b.s. Our singles on the other hand out perform most twins costing twice as much. Is there other twins out there that will outperform our singles, sure. But the cost is high. We've sold thousands to customers that are more than pleased with their performance. The issue with the internet is that a handful of guys complain about some things and you're judged on that as a company. The other thousands of people that are happy and don't post up get ignored. We understand this as a company, however, we've proven our singles in a big way and we'll continue to do so. Unfortunately the twin fad is hitting full force and we'll make a twin to suite it. If it were up to Steve we'd stick with simple singles that hold four digits. |
Chris my stage 3 from you all rocks!!! Now if we can get someone kicking ass and building better master and slave cyl's i'll be happy.. I've got about 1200 miles on your stage 3 and its FANTASTIC.. little bit of chatter but who cares ;-)

When we first installed my clutch as part of the build, it took a little getting used to starting off, there was quite a bit of chatter if I didn't rev the motor a bit before coming off the floor, and it felt like it was grabbing a little even with it on the floor say sitting at a light... I got to throwing it into neutral all the time as I approcached lights... We eventually pulled it when we were removing the tranny to address the synchronizer and shift fork issues. We took pics of it and ended up sending it back to 'ACT, and they did some work on it... It seems to respond better, and the chatter has lessened with driving time, but when my builder pulled the transission this last time, he said the assembly looks a little worse for wear.. I'm going to try it for a while longer and then may have to consider other options... I can say that I have never had any issues with it clamping, though traction has been a part of that... I feel like it has the potential to be a good clutch, but I'm not sure how long it will last... I'm considering options as well, so I'll be following this thread... |

Do you guys install and set up big hp rated clutches at your location, or are you strictly retail... I hoping someone does an adjustable clutch slave/master cylinder soon. The reason for the big hp question, is we are soon to up mine into the 1200 or so rwhp range... And 1250-1300 ft/lbs... Does monster make anything that isn't an on off switch clutch for this power level... The above power will not be full time... It will only be for track showings and then back to my current power level for street driving... I realize I may be asking too much, but if I don't ask, I'll never know |
