7ishNZ Posted June 15, 2009 Share Posted June 15, 2009 I was trying to come up with a better idea than a ring gear and auto style starter motor... how about this... What about using an auto starter motor with a small multi-rib v-belt pulley in place of the stock gear, driving to a similar but larger pulley on the driveshaft, with the belt being tensioned by a slip roller when reverse was required. You could control the motor with a micro switch that energized when the belt was tight, and you could ensure that the belt did not drag on the driveshaft when not in use... That way you would prevent the large shock loadings of a fixed ring gear, it would reduce the current drain of a solenoid( not required) and the high start torque power drain, and you could mount it anywhere you had space. Comments, anyone?? Link to comment Share on other sites More sharing options...
Spaz Posted June 15, 2009 Share Posted June 15, 2009 Sounds good, but I don't think the belt can handle the load of moving the car, and would just slip when put to use. just my two cents. Link to comment Share on other sites More sharing options...

Comments, anyone?? What's wrong using the quaife reverse box unit? I used to have a reverse box for my hayabusa http://mjmturbos.com/images/reversemount.jpg Edited June 20, 2009 by BusaNostra Link to comment Share on other sites More sharing options...
7ishNZ Posted June 22, 2009 Author Share Posted June 22, 2009 Mainly... the price!! Also absorbs some horsepower and adds weight. Link to comment Share on other sites More sharing options...
Hank Posted June 22, 2009 Share Posted June 22, 2009 Who needs reverse? I pulled mine out last week. Saved 28 lb. Plus I get exercise pushing my car backwards. hahaha Link to comment Share on other sites More sharing options...

I have a narrow driveway that I back up into the garge every time. But my car came with it, and if it goes bad, I am out of luck! and will be pushing like Hank.

TurboBird Posted June 26, 2009 Share Posted June 26, 2009 I have Quaife reverse also. Holding up so far with 22k miles of 'street' driving. Has leaked since new - Quaife says that's gonna happen unless you install breather tube and recovery tank - I did not. Quaife also says ok to run on less than full level of lube. I put in about 50 ML of lube per year and just drive (usually about 2.5-3k miles/year) - I have an old garage and don't mind the oil drips. I believe the design is dog engagement in 'forward' position, so not much power loss. Reverse is geared and quite 'whiney' when in use. Most annoying feature is the almost 1/4 inch of lash it has that helps the car go into occassional 'death oscillations' under light throttle (no doubt contributed to by the light bike flywheel). Tricky to drive smoothly, but you get used to it. Let a friend try the car for the first time and they will quickly admire your advanced driving skills! But a few eye blurring 11k rpm run-ups through the gears make that all go away. Link to comment Share on other sites More sharing options...

tex Posted July 5, 2010 Share Posted July 5, 2010 i have been thinking of removing the reverse box for a while now - BUT after touring round scotland we were on a tiny narrow road when a huge 40 ton lorry came the other way - - road blocked.. hmmm i couldnt back up (even tho i had a reverse as there were lots of cars behind me) but the lorry driver kept crawling forward! his rear trailer wheels nearly ran over the top of the right front wheel! woaaaahhhh! reverse quick.. blasting the air horn and reversing as much as i could i saved being squidged... think about it first..
