Seriously the mount is my concern. I know for sure that bugpac had total failure of a similar narrow bearing mount with much less HP and had to redesign. His also looked to be bulletproof but IMO only, there has to be serious consideration of the mount rigidity.. It will take mounting the engine and mount into one very stiff,rigid structure that will not allow any flex not only at the mount but also no flex of the motor mounts and frame between the engine and drive. I know I argued high and low about my not having any flex issues with my first drive on the BBQ buggy but after much thought and rethinking I am certain frame flex was the culprit. The chain will exert,as I'm sure you realize, a large amount of twist into that mount. I'm sure that you'll be able to figure out how much steel to throw at it but ,again, be mindful of the entire cradle package for the engine and drive to ensure chain alignment under WOT power. Remember what we get away with on smaller buggies will bite you in the ass when busas or Kawi1400 or any other really high output MC engine is used. They will twist stuff every way but loose. LOL!!! I'm liking your work.
I admit I'm concerned with the leverage the overhang of the sprocket will have on the chain. The mount with only a single bearing concerns me only from the standpoint of rigidity and possible chain alignment issues the single mount might have due to any possible deflection that will occur under power. The mount will need to be super rigid.Engineer is plenty educated enough to be able to calculate the deflection loads to see what the deflection will be and how much chain alignment will be affected sooooo,engineer,how ya gonna keep it mounted rigidly enough to prevent any deflection ?
fabber I talked to that same member and it was an interesting conversation but alot like talking to a wall! as far as the bearings go engineer have you actually cut one aparts to verify it's a double tappered instead of the more common double ball bearing? I run wheel bearing hub combo's on my v-6 rail which is 1600 lbs to 1800 lbs wet. the bearings came off the front end of a 97 cherokee 5 on 4.5 bolt pattern thru what ever other years and I also believe they fit the v8 grand cherokee models but doesn't matter I can say this they are not 2 tappered timken even though the box said timken on it they are 2 roller bearings as far as i could tell from a website i finally found with some info on them. no I have not taken one apart but will soon. ok the reason I even ask is because when i jump my rail upon landing there is enough flex in my wheel bearing the my rotors lean over just enough that my brake pedal gets just a touch soft on the first push. but only when a hard load is put to them like jumping! fast corvairs is running the same bearings I believe I wonder if he has noticed this as well? you should hollar at him and ask! I'm just saying there is a reason factory brakes are on a slide so they can move with the rotor! just something to think about.
