Both those companies are probably your best bet. I was looking at act but its just too pricey. So I emailed southbend and asked about modding my stock pressure plate and modding the stock disk to 550 ftlbs for $375. So I think that is my best option and might be good for you also.

I'm aiming for 600whp and I'm using a act xtreme pressure plate with a 6 puck unsprung disc. This combo is supposed to be good for 632ft-lbs. I haven't driven the car with it yet though, so no feedback there. At 600whp, you're pushing the limit of what any r154 single disc clutch can handle. From the reading I did, unless you are going to invest in a twin or triple disc, don't expect to get a clutch that is very easy to drive that can hold that much power. Any single that can hold that much you are risking crank walk, so definitely disconnect the neutral safety switch. Also make sure you take your time and go through a proper disc break in procedure before cranking the boost up.

yup definetly , already disconnected the neutral safety switch and i honestly wish i could afford a twin disk but with my power goals i might jest keep it under 600hp with a decent clutch kit...i dont drag or street race etc...i cruise but there are time when i want to get on it so the car wont be lazy lol..so i just want insurance of a clutch that can handle my goals..my car currently have a Soarer r154 with MC internals and 2 out of the 3 forks upgraded to the DM version..when i had my trans built they never had the 3rd fork available which i believe was the reverse fork..i use redline fluid as well

Call South Bend and ask about this clutch K16063-SS-B it's Rated 600 ft lbs and is very street friendly. Also just a FYI South bend often time under rate there clutches. I have seen this clutch surpass the 600 ft lbs on a dyno

Hey give South Bend a call @ 1-800-988-4345 and ask for John. From what he told me the endurance is a drag race clutch. But give him a call and he can explain better to you. Also the price went up quit a bit from the last time I check.

Yes sir ..I have a friend who had a stage 3 drag 6 puck clutch he had laying around and was dynoed without the clutch breaking in so the clutch slipped so I had a part he needed and just end up trading so I'll have the pressure plate n disk shipped to SB for a rebuild

from what I understand you will need a 500 Miles break in on stop and go traffic with the clutch before going on a Dyno.

I'm current breaking in the SB clutch on my MK4. It's so hard to resist doing pulls, but I hear it's worth it! :O
