Brent, very good qestion. I would like to see the dyno pulls as well to compare the curves. I have to make a decision to go with something by the end of the week, to get the engine back and ready in time for test-n-tune.
Hadn't plan to drop this much, but maybe there is something here over the other modders to justify the extra $170 and $250 cost difference. Maybe it's in the bearings....
The bearings are the extra cost. There is also more hand, and machine work. I actually make less on the drag mods.
The bearings I use are not your run of the mill ceramic bearings. They are specially made for me to my specifications. The bearings start out as Novarossi bearings. The bearings are checked for play, and roundness. Matched ceramic balls are installed in the bearing to make the best clearances. You would be surprised at how far off some of the high end bearings can be as far as the races not being perfectly round, and the balls beings slightly different sizes, too loose, too tight. This is why my ceramic bearing kits cost so much. I am hardly making anything on them.
Great bearings are an easy way to free up HP.
I will have to search some archives for a drag dyno pull. No promises. I will have a database of dyno runs, and comparisons in the future on my website. A few months away though.
