If this was 1960-1980 I would know what to run but technology has changed so what are the SouthWest G***er types running for a clutch & pressure plate these days? Building a '57 2dr. 150, blown BBC, 4 speed, slicks, 700-900 HP. Thanks!
A friend of mine used to run a Ramp power grip HD with a billet steel flywheel, then switched to the Defiant model which has smoother engagement at lower speeds. He drives it on the street alot and takes it to the track. The DefiantX is an adjustable pp, which needs occasional adjustment but doesn't take much more time than adjusting a conventional clutch linkage. This is most likely the set up i'll be looking at in the spring. Can't decide on a 13lb aluminum flywheel, though. I understand how it hurts the launch, but I think i'll enjoy it more once rolling. I do have a pretty flippin big tire though and hate to bog off the line...decisions, decisions... -rick.
Either that or pull the trans back. He says it's just yearly inspection. I've never been there when he does it and i dont know what bell he runs. I have a Quicktime bell and there's neither an inspection plate, nor bottom cover. -rick
What Trains ? m22 or a typical T-10 ? You will need to be looking into Liberty Jericho G Force ect Look @ Torque #s Not Hp , BB , Blown & hooks needs to be strong with grip ,, Multi disk, or a slipper for adjustability if you want to do work & service frequently on street full lock up , Track slip , Then you need to service steels . I do not see why a inspection plate Can be added to Quicktime , I think 12 or so bolts Required , There are other manufacturers of Can / bells with inspection.
A light aluminum flywheel sounds great but you give up the launch. Back in the '60s I ran an 11# Scheifer aluminum flywheel and my 2800# '55 Chevy ran consistent 11:40s. My friend Dave and I installed his small block in my car and it ran 2 tenths quicker, best ET was 11:21. Dave's engine made more power than my 327 and it had a heavy steel flywheel The launch was significantly more consistent.
If planning much street driving, I think a multi-disc clutch (thinking dual disc) is going to be best. The old days of single metallic clutch disc with a high force pressure plate is tough on the street. Add in also tough on your left leg. The multi-disc clutch can be more forgiving clutch material, and having twice as much friction area it can get by with a lower load pressure plate. It will still work good on the strip, just tailor the clutch material to handle the application, maybe a hybrid with combination metallic and organic? There's been a lot of good clutch development with all the high power blown LS running on the street and track.
@brigrat Many on W -Coast . If not already researched CS1 reasonable I have seen complete Can ,clutch pack , Fly , shifter , 2-5 speed , reverser @ 3k . but replacement parts, some discontinued can be very expensive and hard to find, Planetary $$ Even from Lenco . ST New around 10k . I was Not trying to be Negative Most do not realize Most after market are rated under 500 Tq ,even auto around a 2,800 pound or less vehicle . unless $$$ .. Bang for $ , TH 400 dollar for dollar good strong oem with a few upgrades . I wanted to run Lenco in my 5W Even 2 speed w Reverser with use of stock seat will not fit. My 5W R-Rod , I swap around combo 500 tq - over 6 00 tires between 275 -315's 4-link change per engine & tire

Check what Mike Finnegan is using in his blown Hemi 55 Chevy , he’s been running 8,40s in the quarter and doing his drag and drives. He’s got a slipper clutch that he has got dialed in. He has gone over it on his YouTube channel…
If you’re thinking about running in any of the SEGA races they require a clutch shifted four speed but then I don’t know if they have any blown cl***es.
I ran a car with that kind of power, 9.63 at 141 weighing 3500#, aluminum flywheel, ram sintered iron adjustable 10.5" clutch. G force g-101 4 speed, never broke parts. I would sell the m22 and apply that cash towards a transmission that can handle that power reliably. The sintered iron clutch is adjustable and has to slip at the launch to avoid parts breakage. BUT the sintered disc is heavy and doesn't go together with a syncro transmission, it won't shift with a heavy disc. You have to combine this style clutch with a face plate style trans. It all works together.
I don’t know what they can get away with now, I haven’t been watching the races much over the past five years or so. They were off YouTube for a while and on payperveiw and when they got back on YouTube I was out of the habit of watching. I know that SEGA is owned by someone else now and maybe the rules have changed.
