One thing not mentioned much yet is cam profile- steeper ramps creating stronger or harder shifts. flatter angles making for a slower smoother feeling shift. Dr spring can effect shift force also, # of lb per inch if a Dr spring has say a 140- 260 vs 140-320 this will also effect speed of shift .
Ive read Aaens book 10-15 times years ago and it is a great book for the can.lol. you cant read it to many times.
Ive clutched all my sleds Ive owned and have had good luck and enjoy it.
Some steps on how to start to clutch your sled. -btw I dont know it all or the 1/2 of it but that heading will help me get some good feed back.lol
-constructive criticism please.
I ussally throw weight at it till the desired shift RPM is right -to light of weight and over rev- to heavy and slow to pull or cant pull the desired rpm.,dr spring for engagement with a reasonable rate and tune "play" with the secodary for back shift and no slip & cool clutches.Im a bit guilty of going with to staight of a helix. lol. Still learning
What Ive came across on my presant sled is it does not over rev so its hard (for me ) to know or figure out what is the right cam weight should be . as an example I went fron 68gr, which should have been to light, to 75gr weights of simalar profiles, All shifted at 7950-8000 rpm w/ same dr spring. back shift was bad w/75gr so went to 73.5 and tightened up sec and now its ok but still a little slow on the backshift. I think-beleive there is such a thing as to much belt preasure when it comes to the secodary. But how to know when is to much.??
spiderman thx for posting that link to teams spreadsheet. very interesting Im shocked at how little belt preasure was effected buy helix angle ??? It made no sence to me, great.
I look forward to hearing others means of clutching.:beer;
