There was a time that you had to have Cale's $2200 adjustable aluminum cover centrifugal assist diaphragm/iron setup to be competitive in Coyote Stock. With the 'tamer now in play, 5 different off the shelf clutch brands are competitive. Cale's couple of die hard customers are still quick/fast with their centrifugal assist PP's and wheelspeed, but every single event so far this year has been won by a dead hooking ClutchTamer customer. This is a class where everyone has exactly the same spec sealed crate engine and identical ECU programming, clutch tune & reaction time on a .400 tree is what separates the winners from the losers. 10.10@130 running at 3100lbs from a factory sealed 302ci NA crate engine. Wallace calculator says they need 593 fwhp to go 10.10.
