been out ofthe game for a while and looking into new clutch..
I used to live on here and its been a long time just checking on some info on is there any new clutches out the can compete with my ls7 clutch price and performance? I was one of the 1st people to ever do the swap on my camaro back in jan of 2006. i loved it but after 11 years 65k miles
its time to swap. just looking to see whats out there now that i have to put a new motor in my car. My car will be looking at a 500hp car, 4.30 gears, 3200lbs
My 91 RS LS1 383 has a Ram HD. It was fairly inexpensive but it's stiff and a bit grabby. While I don't lie the RAM HD it has held well at 465 rwhp in the RS. My girlfriend likes the stiffer than stock feel of the RAM HD.
My 99TA has a McCloud RXT Twin disc any this clutch is near perfect for me. Feels and drives about like stock. My girlfriend says it feels a bit light. I say it's just right. Her son agreed with me. The TA has a 416 and should make 500+ wrhp. The RXT should be good for well over 500hp. It's held everything so far.
Next summer the RS will get a McCloud Twin disc RXT. I think it's worth the cost for the performance and feel.
BTW - I've driven an LS7 and LS3 clutch a couple of times in various cars. The RXT would be my choice.
I'm currently running Monster's LT1-S dual clutch and I love it. Feels like stock pedal, hooks up nice and smooth and handles all that I can put on it with my 315's on back.

RXT drives awesome and rated at 1000hp..... I've got them in most of my vehicles. Good price for a twin disc and take the abuse.
I've also had a Ram HD back in 2005 and it was crazy stiff and grabby. Not very friendly. LS7 clutch with steel flywheel weighs a ton! Sluggish revs.
Without some way to force the clutch to slip a proper amount, installing a 1000hp clutch behind a 500hp engine is going to make the car hard to launch at the dragstrip.
My past clutches have been stock > Spec stage 2 > Monster Stage 2+ > Monster LT1-S. The twin style clutch will be all I ever run after this one.
Cool thanks , I have a Tick Master and really don’t like it with the LS7 clutch . The engagement window is soooo much shorter from full released to full engagement than the stock master . I’ve had the car for 7 years , the LS7 clutch for 6.5 and the Tick master in for 1 year.
Looking at the Monster LT1-S now , thinking about swapping out the master too.
A lot of clutch selection has to do with personal preference...
If you want stock feel and big hp capacity, go twin disc, specifically the tougher ceramic or carbon material if you're gonna beat on it with a sticky tire.
If the car is 99% street and won't see much over 500hp (flywheel), I'd recommend the Monster Level 2 single disc just from personal experience...ran it with the Tick 7/8" master and 18LB steel flywheel and I absolutely loved the feel, performance and drivability of that setup over stock...definitely stiffer, but I actually much preferred that...going back to stock master or a smaller tick master would lighten up effort
...took a beating on drag radials @ 450+whp and when pulled out at 15000kms, it still looked next to new

A twin disc allows you to do this, It's not nearly as grabby as a stout single disk clutch.
I just went from ls7 to a McLeod RXT, McLeod billet 30lb flywheel. It Has a nice engagement window and is not too grabby. I was told by Slowhawk who installed it to drive it easy for at least 500 miles of stop and go driving with No WOT runs. I did that and it pays to break it in properly. I now have a nice smooth clutch that holds like a beast with smooth engagement and a pedal as light as my LS7. (During break in it starts smooth then starts to chatter and goes smooth again towards the end of the break in period) That was my experience with the RXT.

Installing a 1000hp twin behind a 500hp engine, then depending on your foot to do the modulation for a proper dragstrip launch is not an easy thing to master. A beginner might get 1 in 10 launches right, with a high probability of breaking something on the other 9 launches unless it's a 500hp car with a 1000hp drivetrain.
I'm not saying a 1000hp twin behind a 500hp engine is a bad idea, you just need something more reliable than a simple foot release if you are going to take it to the dragstrip. Magnus, Tilton, and ClutchMasters all have launch control devices that will make clutch pedal release rate more consistent, as long as you are launching from a full tree where you can anticipate the green. If you plans include "flashlite" starts or launching from a pro tree, the ClutchTamer also controls clutch pedal release rate, but with much quicker reaction time.

Most serious drag cars are going to run a auto trans not a stick besides it actually has little to do with HP anyway, It's torque you're dealing with off the line and every engine combination is different, Even the flywheel weight comes into play.
If you are using a positive displacement supercharger like I am then you make gobs of torque off the line yet I probably only make 500hp or so to the wheels. I'm going to need a better clutch than a NA car that makes 500hp to the wheels but not nearly the low end torque.

Plenty of serious drag racers running sticks. Only time most see "low end torque" is when a mis-matched clutch pulls the engine down waay too fast.

I have the LT1-S with a Tick. I'm looking at picking up a Tilton 75 Series 13/16" bore master to replace the 7/8" unit.

~500 whp with 1000hp drive line - that's me with the 99TA & 91RS. Both are built for 6000 rpm side stepped clutch on slicks - so my clumsy *** doesn't destroy anything up with 465 whp and ~5xx whp.
One friend has a McCloud RXT Twin in his stock drive line 4th gen fbody. He doesn't have clutch issues launching the RXT on the street with his 328 whp car.
Most beginners have issues with six speed cars regardless of the clutch. They seem to have more issues with the grabby single disk clutches like the RAM HD. I know that clutch was a nightmare for me for a long time.
