You gain a few horsepower. I think we gained .2 seconds by deleting p/s on the 1/4 at grassroots. Somewhat noticable freer revs when my PS blew a leak at the dragon this past summer.
Sick if you read my post I gave you suggestions on ones to look for but I guess that wasn't important.
Remember $25ish for a quart of fluid if you can still get it as there was only a couple bottles left in the US last time I saw. You'd definately need more than the pump which is why I said figure out who has an XT6 locally from car-part.com and go from there.
BTW I've had mine locked and the current drop isn't even noticable on the voltmeter of my 6. Most notice you get is when you turn the wheel slightly while not moving. 75amps seems like a lot based on the wiring that is there!
