  2. In and effort to reduce the spam on the site, several years ago I had went to a program where I manually approve each and every new registration. This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

Question: Posi and mileage/HP

Discussion in 'Got gears?' started by 12lives, Jun 1, 2005.

    12lives Control the controllable, let the rest go

    If you go from an open rear to a posi rear in the same car - how much additional HP drain is on the driveline? How much does this affect gas mileage, assuming the same ratio gears? What have you experienced?

    No difference at all. The posi is only being engaged when the one tire isn't getting traction. Other than that, there is no difference.

    Only thing I ever noticed was the car handles better

    Mileage tends to go down as a result of being able to now spin both wheels, which is twice as much fun as spinning only one. The main culprit, however, is not the posi, but the increased weight in the right foot. :3gears:

    ...and then there's the corresponding decrease in tire life too!

    Not to mention the extra wax you have to put on the rear quarters

    I got a tip at Salem last year to spray WD40 on the lower fenders and tail pipes so the rubber just wipes off with a towel. Just thought I'd pass that along.

    What?

    NO WAY!!! You WANT it to stick! So you can say "Look guys, Both quarters and LOTS of it! My car does he!!acious sideways BURNOUTS now"! Gas & tire mileage decreases :3gears: but you can't get rid of the GRIN! :laugh:
