Violent Take-Off Shudder

Its a big block car with 2" TTI headers.... Nothing is a 4 hour job....

If I swap the clutch out, I need one to hold 600+ HP. That perfection clutch will be toast in 1000 miles. Any other suggestions of clutches for high hp applications?


Ok, now I see your mistake. You are buy a clutch based on horsepower. That’s not the way to do it. All those “high horsepower” clutches are nothing but violent parts breakers.

Here’s what I’d do. My advice is worth exactly what your paying for it.

I’d go back to a Borg & Beck cover. I would use the McLeod heavy duty rag (organic) disc without the marcel spring. I would take the cover to a local shop that does frictions and such and have them set the spring pressure at 2400-2600 pounds and use no roller assist and send it.

You may be able to buy a cover that’s already at that plate load. I’m not sure on that, because I can’t find my McLeod catalog.

If you are going to beat on the car with slicks then you have to either buy a different clutch (what I’d do) or buy a Clutch Tamer. The clutch I’d run if you’re going to beat on it is a McLeod Sof-Lok but that clutch was 2200 bucks last time I looked. You can get a similar set up from Advanced Clutches or Black Magic Clutches.

If you are just street driving all you need is the first clutch.

Don’t get caught up in horsepower and clutches. It’s a parts breaking disaster.
