Where do you leave and shift at? Are you running counterweight? If I had to guess if your running to much counter weight and its locked up tight at your shift points. That is just a shot in the dark.

You have too much clamp load at your shift point, whether base or counterweight induced. Peak torque is at lower rpm where counterweights are less effective. If the base is quite low and you make up for it with counterweight to get enough clamp load at peak torque, it is easy to then have too much at the higher shift rpm.

For the last time you don't need a Youngblood clutch to go fast. PM me and I will direct you to some very fast cars in ND in the records section not running that clutch.


As others have stated give your base,cw if any and rpm shift points. That will help. Good luck.

The pressure plate has a 280 lb base, I started at 5 turns out, and backed it down until it flared on the 3-4 shift, and added 1/2 turn. I normally leave it like that until it flares again, however many runs that takes. I don`t really play with counterweight, as I can not remove the bellhousing in the car, engine has to come out. For counterweight, I have the short steel bolt and nut, I believe that is about 6 grams per lever. I launch at 6000-6200, and shift about the same.

Do you shift with or without the clutch ?

Pretty much uncalled for as nobody even suggested it. Nobody.
Now if you have a problem with Advanced Clutches, whether you can't afford one or you think they don't work, take it elsewhere.

I would look at the counterweight as well. Good luck!

although I can only suggest what could be going on as I only have 25 passes on my combo ,the one thing I can tell you is if you get a data logger you can see what is happening during the run ,,,when you make changes to the clutch you will be able to see it on the graph and compare several runs together,,,i have a rpm data logger 10 channel with the basic engine rpm,drive shaft rpm ... it also gives you a R.A.T number witch is the slippage between the engine and input shaft ,with that system you can add other sensors,o2's, it takes the guess work out of runs that went bad(loosing traction down track,bad starting line or slipping the clutch) its not priced bad and its made in America and they always will return the phone call if you have a question, I have learned a lot and still learning gmonde

Rory, do you need that CW? Have you ran without it?
