Great video. I only have one small issue. I’ve been running sintered iron/soft lock clutches on the street for years. It is by far the best set up going. I encourage anyone running a street/strip stick car to use a soft lock clutch. Again, GREAT VIDEO. And I subscribed.

From my experience with slipper clutches I think three things should be stated: First, sintered iron is high maintenance with the deglazing process and constant adjustments and tuning. I think many racers would find the effort involved intolerable. Second, they chatter, which makes staging the car more difficult, deglazing helps but returns rather quickly. Third, sintered iron disks don't work well with conventional syncros.

Thank you for the video, it's very educational. Can you please tell me which clutch brand / model was used in the video? Can you please make a video going over the calculus portion? Are you available for consultation on clutch related subjects in the future, and if yes, what's the best method to reach out?

Pressure plate was a McLeod Soft Lok. Disc was Ram 4135. I'm not a clutch consultant, maybe contact Rob Youngblood at Advanced Clutches or talk to the manufacturers. The calculus is shown on the board at 16:45, if I made a detailed video about that I'd probably lose subscribers ;)

Have the billet 10 inch long style ram, 690 base and 60 gram on levers it will not do a burnout and doesnt lock up only gets worse as vehicle gains mph or shifts higher and slips too much

Power/gearing/weight? If you've driven through the clutch excessively, everything will need resurfacing before it holds properly again.

So the counterweight is going to be a curve and not linear due to the engine speed? And the more the counterweight the the quicker the clamping force increases? so could you, or would you want to decrease the static force?
@The_Performance_Laboratory

Correct, counterweight force is not linear with RPM. More or less counterweight, combined with static force, is a tuning variable. Too much and the clutch might lock up too aggressively at the launch, too little and you might still have clutch slip in high gear.

'SCIENCE!!' nice Thomas Dolby reference, but seriously last time I raced a clutch car we used a 3700lbs clutch a 50lbs flywheel and left at 8800 with a 427 chev with 14x32 tires..oh and a 557 gear. I have to forget all that now with the 55 and relearn all this. I may need your cell number Ed..lol great vid

Can we get Exel page to calculate about: Diameter where pivot are located. Weight and lenght of arms? I don’t use static spring and pedal but I use springs to keep clutch open.
@The_Performance_Laboratory

If I understand your question correctly, I can't provide a spreadsheet to calculate centrifugal clamping forces, as you need to know all the geometry of the levers, including where their center of mass is, and the static lever angles (which change with disc wear), as I don't have that information.

@@yvesgia Yes, the math isn't that complex, it's getting the geometry measurements that is the challenge. However, I will warn you I've done this for my clutch, and bought commercially available clutch software, and none of that helped my program. It still fundamentally came down to trial and error to get the clutch setup right.

I have an 87 LX stock motor t5 4.10 gears best 60' so far is a 1.69 mid 13's @ high 90's. Currently has a stockish clutch and a clutch tamer. I have been pleased so far. I am adding a turbo and I am concerned it will slip too much with the additional power. Any recommendations for where shop for a clutch? Street/strip / drag week car.
@The_Performance_Laboratory

I have no recommendations other than talking to the clutch companies directly. With the turbo, you'd probably want a sintered iron disk as a minimum, and possibly a dual disk to cope with the slip/wear better.

I would like to see the derivative for your chart....I race a 7.25 dual disk sintered iron clutch. I race a 406 camaro. I didn't see car weight, tire coefficient,or gear ratio in your formula. Also base pressure test fixture would be helpful in setup. I made one if your interested. The question I have for you is: how long do you slip the clutch at the hit? McLeod says a couple of tire rotations on the start line. Love to see other gear bangers. I have years of notes with data recordings also. Thanks for the video!

There was no derivative in the calculus, only integrals. And you're confusing tractive torque and clutch torque capacity. Ideal amount of slip results in the quickest ET and will be different for specific combinations and track conditions. Thanks for watching.

It wasn't possible when I shot this video in the winter, but my plan was to follow it up with another video on clutch tuning (and data logging) at the track, but for various reasons, it hasn't happened yet.
