So that clutch ( Mcleod Organic) stated above with what PP? will it be fine with no tamer? good enough to street drive but have fun dumping the clutch or power shifting occasionally when I want to have some fun?
If the pressure plate isn’t over about 2400 pounds it won’t break parts. If it’s over that it will start picking off the weak parts.
I learned it this way.
Pressure plate load is what kills parts. When I was in high school I killed a clutch. Cost me 250 bucks because I lost the race. In 1980 that was a sizable chunk of cash.
Not knowing my *** from a hole in the ground I opened up the DV catalog and found that junk assed 3500 pound “green” “race” pressure plate. What crap that thing was.
Not only did it cause the firewall to flex, the clutch linkage was bending like a noodle and when I took it apart the cover was fracturing because it wasn’t strong enough and it was flexing too.
And it broke parts even with a rag disc. Just junk **** and Chrysler sold them. You’d hope they would know better.
So you either need an aggressive disc with very load plate load OR you you can use a disc with a lower coefficient of friction and then you have to up the pressure to get it to lock up.
Sooooooo…the higher the plate load (pressure plate spring pressure) the more it will break parts and drive like a toggle switch.
Thinking of plate load like a hammer, the higher the load, the harder the clutch will hit your parts. High plate pressure is a bigger hammer.
That’s why most guys trying to go fast and not kill parts are using what is commonly called a soft lock clutch.
It uses a very high coefficient of friction disc and almost no plate load. How little?
In my prior race car that weighed 2800 pounds with me in it and with a soft lock clutch I used 660 pounds of base pressure. That’s it.
I had to change the pedal ratio in that car because I needed some feel on the clutch pedal.
In my street car now I drive around with about 990 pounds of plate load and IIRC 20 grams of counter weight so it locks up and doesn’t slip when I don’t want it to.
At the track I’ll drop the plate load to about 800 pounds and use 5-10 grams of counter weight.
And that’s in a 3600 pound car.
So the less aggressive the disc the more plate pressure you need. More plate pressure is a bigger hammer beating on your parts.
With what you have you need a much less aggressive disc because your plate load is fairly high.
