To day I met up with one of our members ,Padgett I delivered to him a 2.89 differential . he has a 6 speed which means he does not need a tcu to control his gearing, as soon as he gets it installed he will let every one know, good or bad. we thank Padgett for being the first to reduce the gearing, example! most of you with a 6 speed know how ,when you take off from a red light , just about the time you get in the middle of the intersection, you have to shift to second. you can't run the gear out,(car in front of you) so is first gear any good at all, Well Padgett will answer that question for us.
Now what about cruising on the highway ? with about 13% increase in speed and about 8% less rpm,Oh and about 4% increase in gas mileage . you notice I said about because Padgett will let us know the real numbers.,,he did say it may be a while before installing the diff into his car.. he has to finish what he has planned for January.
when he does install the diff with 2.89 gear, going from a 3.27 to a 2.89, we are going to sit up and take notice
we await the results, thank you Padgett---- jim
