Doesn’t surprise me. Most guys want to run the 100 dollar floating idler junk. The 3 gear fixed idler gear drive is dead accurate, stupid reliable and hard to screw up.
If anyone tells you gear drives cause harmonics, break parts and cost HP, tell them to show you where any ASScar team, any PS team, any F1 team has published that data. It doesn’t exist. The only things I’ve found has been testing done with the floating idler gear system. It’s junk.
All my drag stuff had a GD. With all the crap I broke, never once was there any sign of crank or cam distress from harmonics. Junk lifters did more damage than anything, and a timing chain or belt wouldn’t fix that.
