I offer to pay give anyone $50 who can proved that those cams regrind makes a different in HP on f2/f2T 3-4 years ago. nobody bite, no single dyno #, no prove whatsoever, yet they post pic . :frown2:One of their regrinds I think gained 10-20 hp on a stock engine at 12lbs. The other which was using their tri flow design they didn't have any dyno proof but said its better. Idk I got the one with the proven gains.
That's how it's done. You have to take up the space left behind by the reduction of the base circle.I know with the triflow cam regrinds (colt I think), people ran tiny washer in the rockers as spacers for the HLA's to make up the ground cam gap or the rockers would rattle, with the shims the rockers tapped the valve cover baffle...
I know how HLAs work.:tup:And if you don't think the HLA's collapse on every valve stoke. The HLA's sucks in and squirt out oil, pull the valve cover of with the engine running, everytime the valve opens and the HLA collapses oil is squirted out the rocker top, when the HLA extends oil trickles out the rocker top.
The "lifters" wont perform any different with a reground cam, the problem was the rockers not clearing the valve cover with Crowers tri-flow cam, there is a chance they tested only with a 90+ car with the redesigned valve cover oil baffles. People had to hunt down the right valve cover and find HLA shims themselves.Does anyone have any actual experience with the lifters not performing the same with a reground cam? Colt said that it's a direct drop in so I'm just kind of curious if all of this talk about the lifters on this engine just theory or have any of you guys actually tried one out and had the lifters fail or anything of similar nature. Thanks for all the info though none the less.
