Gear reduction units...
Posted 20 September 2003 - 03:12 AM
this would involve moving the engine back, id assume...
what does 2.18 to 1 compute to when reduction is ran from in the front of the driveline?
unfortunatly they cost a grip...just curious how significant the gearing for off road purposes would be improved..this could do wonders for someone's buggy or hatch!

as far as clutch goes, I pretty much figured one would have to stick with a 3sp AT if they wanted to reap the benefits of using a reduction like this...
wow a tractor huh? Be pretty funny to be driving down the highway, and look into a cut cornfield, to see someone's hatch discing a field!!!
Seriously though, I just threw this out there because I saw a few people on the board fantasize about something like this, and I happened to stumble across someone who actually makes em...
they are availabe for EA81 and Ej22's..
So whose gonna build the next rock crawler??!!!!

Talk about a high-stall converter!
RE the tractor thing. There was a time when you could buy a sort of "tractor kit" for a Ford Model T. GR boxes at the rear axles (think of the setup on the pre-68 VW Transporter: same idea), big rims, etc. People found out pretty quickly that you can't put tractor-type loads through a T's frame for very long -- they break. So did everything else. There's a reason why a tractor weighs as much as it does
Same goes with the hatch -- you wouldn't want to try to haul semi-trailer loads behind one, because actually putting that much torque into the hatch's drivetrain (and frame and suspension) for very long will quickly find all the weak parts.
Short bursts is another matter.
The GR units available are designed to let the engine run in its optimum torque range, and keep the prop from overspeed -- the prop tips reaching the speed of sound, which is bad for props. Or, at least, that's what I've heard.
