Re: I Need More Acceleration
Mate what model do you have? Mk1 all XR6 T have 3.46 sedan or ute, MkII all XR6 T have 3.73 sedan or ute. Don't change you diff gears you'll just light them up. The MkII only has shorter diff because the T56 6-soeed has taller ratios that are closer together. The overall gearing is much the same, in fact the first 4 gears I identical, I have seen them graphed. There is no gain.
The utes are not slow down the 1/4, whoever tested the utes in Motor must have changed gears vereeerrrrry slowly, or backed off halfway down the track. I ran a 14.7 but rolling, yes ROLLING off the line and flooring it, I woul dhave traveled 5 m before the turbo spooled and I still made 14.7! Thats faster then factory and Motor can do! What would happen if I nailed a launch? 14.3 most llikely.
Now, the same can be said about the sedan, its actually a 13.9 car, its piss easy to get low 14s, but you have to rape the shit out of it for a 13.9, but its there.
Now the utes are heavier, very much so, 70kg is not it. My hard cover weighs 70kg. Just to put it into perspective, fulled fueled turbo ute with hard cover, 1920kgs. How heavy are the sedans again? Not quite 1700? thats more the 200 big ones mate, damn near three. So there is your 3 tenths difference.
Also the live axel in the utes will hook up harder than the IRS in the sedans, remember you have more weight over the back wheels. You just need more grip now!
