Clutch plate ###s

[SS/GN]

Been doing some reading and I see many options in the number of frictions used in the assemblies.I see alot use
OD=3
Forward =4 or 5?????
Direct= 6 and as many as 7 or even 8 from alto????

At what performance level do you start adding more frictions.Thanks for the input

The only place I put an extra clutch in is the O.D. The direct clutch I just dual feed.

I see on the Alto site they offer an 8 clutch pack for the direct,that seems to be getting the indivdual clutches thinner and just wonder why.I also notice some shops put 5 in the forward clutch??Interesting ideas.

Milled the OD piston .070 , I think it was , to get 1 more friction .

Is it worth the effort to dual feed the directs on a 200-4r behind a mild 350 ?

Thats very vague...a mild 350 in a heavy vehicle ups the level of abuse. Whats the HP/Tq of said engine, weight of car also rear end ratio?

Sorry about the Vagueness . Please bear with me . I've got a lot to learn .

I'm just guessing on the HP . Probably 250 at the most . Rear is an early Nova 3.08 . Don't have a clue on the torque . This is in a 34 Chevrolet Master . Never had it weighed it but I'm guessing around 3000 Lbs .

An occasional pedal to the metal but , no racing .

Thanks

Back to the original thread,has anyone tried different combinations?Thanks

To add extra clutches in the forward and direct drums you have to use thinner steels. I have tried many different combos. The problem with using thinner steels is they can't dissipate the heat fast enough so they hotspot and warp. Adding an extra clutch to the O.D. is a no brainer. You just cut the piston one clutch disk thickness and add the clutch. No integrity is lost in the clutch pack. Works very well. Dual feeding the directs if needed is the best answer if done right.

Ive tried them all over the last 17 years. I prefer .100 steels and thinner clutches. The line pressure and the way the piston is fed is very important. Ive got over 150 WOT 2-3 shifts on the trans in my black car. I havent touched direct in 3 years. The engine has 800hp. For a 250 hp application in a light vehicle there is no need to dual feed or do any crazy modification. Just be sure the bore on the drum is good and the line pressure is good.

I prefer .100 steels and thinner .

When you say .100 steels,how many clutches do you use in that combination??At what HP or et would you dual feed the direct.Thanks
