Jones Cams
has done some high buck factory projects like the turbo buick indy engines been doing it for 40 years
When you go from a flat tappet to a roller the flank goes inverse unless you increase the duration
They have been able to make inverse radius flank roller profiles work allowing them to use a significant less seat duration for the same or better upper profile
not just that simple as roller wheel and base circle are involved as well as side thrust- not simple tradeoffs
I knew his dad who dynoed our Indy twin turbo Rambler 210 inches 50 Pounds of boost 1000 hp for 30 minuets on the So Cal Champion Spark plug dyno
- we had more torque coming off the corners than any car that year
Indy put in a "fuel rule" that made us noncompetitive
His Brother Rick markets the "Controlled Induction" software take a look at the demo online- google it
