It also costs a lot more than a timing chain set and takes a considerable amount of time and some machining to set up.....all to go backwards in technology sixty years. But if that's what gets your rocks off by all means do it. As of now it's still a free Country.

Has anyone did any back to back testing ? Spintron testing ?
I know the Milodon is expensive and a pain to set up.
But, if you can make them quiet and they last far longer, longevity is something worthwhile.
I have never messed with one but I would assume you can adjust the lash for wear.
If you say harmonics is a thing against a gear drive I believe you. I would think at some point a high end engine builder has spun one up on a Spintron. What did they find ?
It used to be said they cost you 1-2 horsepower. But if it lasts the lifetime of the engine that is not bad.
Now a engine builder, I understand why they do not like them. very expensive and I bet customers don,t like paying the actual time it takes to set one up.
Vs just putting a good chain on, degree it and be done with it. Gear drives are a losing deal for a engine builder.
Getting one to make noise is just dumb. Never liked that noise. I remember the knuckleheads with their 300 HP small blocks in their 75 Camaros making all that racket who thought they were cool.
