That's closer to what I would have expected!! And those numbers would make sense with my analogy of running an Explorer into a brick wall at 70mph or the Expedition at 35mph.I messed around some more with my calculations comparing the SS and speedpro. I got the numbers to work out to 16 tons on the SS and 28 on the Speedpro using the same assumptions. I'm surprised Speedpro felt compelled to go for 28 tons when SS has a long history at 16 tons. The forces on the gear teeth are insane at 28 tons combined with a pinion speed that is to high its just asking for disaster.
I really wonder how many problems these units would have had ... if they were geared correctly? No different than anyhting else ... you start jacking up force, components will start breaking. If I threw a blower/supercharger on the wife's grocery getter, without changing any stock internal engine parts, it aint gonna last (but might be fun while it did, lol).
Get it geared down ... and I really think you will be fine. I still think you could turn the original clutch pulley down (making it into a stud shaft), and bore out a smaller pulley to fit. If that doesn't work, have someone weld the smaller pulley to the clutch face (old pulley ground off).After all that ranting...I still don't, for the most part, regret buying this thing. The ability to split wood with the speed of a kinetic splitter, and saving a grand, still outweighs the issues. Just wish I didn't feel so much like a big furry domesticated rodent.
Also, interesting that the Speeco folks that were coming on here have gotten really, really quiet.:confused2: I wonder what's up with that? Maybe they actually tested the new racks and they are still failing? Maybe they are finally realizing that they need to slow things down? Hmmm ... if you think about it ... when we really started talking about the speed being the underlying issue, is about the time they stopped posting. Coincidence??
