Hello. I am running stm weights in my supercharged nytro. I am not pulling the rpm I need. And I was wondering how much and where to take weight out of. Current set up is
Tip. 4 washers
Heel or first hole. 2 washers
Ulmer h helix at 60 deg. Stock sec spring
I'm running around 8200-8400 ish for rpm. Saw 8600 at one point. Looking for 88-9000 rpm
 
Clutching is testing, testing and more testing. It's a million different ways to do it. We are all different, and we wants the sled to act in different ways. You have to try to find your best setup. You can remove in the tip until you see your wanted rpm. Thats the easiest way
 
200 rpm. Never ever just do one setting to a one of the weights always do a setting to all 3.
Yup. I figured that. Lol. Thanks that will help me quite a bit knowing how much RPM for washer for fine tuning. Ulmer also wrote me back and told me what to try also from initial set up. But now it should be easy for me to fine tune. Thanks
