Improving mileage?
Posted: Wed Aug 06, 2008 7:50 pm
I know there is a OD conversion out there for the transmission/gear box, but there has been some trade offs. I assume this OD conversion allows for higher speeds and improved MPG's?
I was wondering if there was another way that may keep the original gear ratio spread in the transmission and allow for greater MPG's by cruising at a lower RPM.
I think we all agree that the gearing in the Low gear range for offroad use is not to be altered. However the High gear range for regular onroad driving seems to be geared to low. Some have suggested that they don't use the first gear during regular driving due to it being to low.
I was wondering if the High gear set in the Hi-Low gear box could be bumped up in ratio so that we could cruise at 55-60mph at say 2500-3000rpm. This should improve our overall MPG's. I'm not talking about a big change just enough to keep the RPM's down to a reasonable level at cruising speeds.
Are there any gears available that could achive this, and is it possible?
Any gear/number crunchers out there that know what gears are needed?
