4.44 rear end and turbo mix
 

do you think that is a good idea for the street. im planning later after i finish the turbo setup, to put a tII tranny in my car, with probaly a 4.44 gear in the rear end. what you think?

There has been a bit of discussion on this topic on an Oz forum, and it seems to be a very popular choice for street cars.

I would go either a 4.4 or 4.1 with a TII tranny. Most likely the 4.4. It'll get the motor into the rev range it likes and is certainly better suited to a turbo rotary.

Go the 4.4s

when I switch to a ford 9.0 rear, I will be using a 3.73 rear end. Maybe even smaller. It will provide Less wheelspin, it will create more load (good for Turbo's), I will have a usable first gear, and a lower highway cruising RPM. A rare win-win situation I believe.

But that's just IMO.

BTW, that's one of the ways the 1000HP Street-class Supras finally started to get really fast in the 1/4. Lighter flywheels and shorter gear ratios made for less wheelspin and more forward motion of the line.

My mentality is for 99% street use, so that's my opinion.

However, if you're on slicks like Steve and other hard core draggers are, then go with the high gearing. Wheelspin is not a problem on huge slicks with only 15lbs of air pressure in them.:p:

15psi in the slicks?! Are you putting it on the trailer or something?? :rofl:

When I did 10.8 on the weekend, I had 9.5psi in each slick :D

My bad. 9.5? Damn, that is nothing. I am suprised you can even get back to the staging area. I have never raced with true slicks, So I didn't know that you can go so low with them. I have raced with street radials, but, you do need some air in them to turn, or you'd screw up the rims.

ALSO:Steve, what do you think about my "3.73" rear end idea? - for street use? I've been wanting you opinion on that for a while.

What happened? I thought you were shooting for 9's? Did Something break? I know you've gone lower Et's before.

is not mainly for drag racing, probably a few time to see the improvement but is more street and road course use. ill probably stick with the stock gear. thanks :D

Fried the new twin plate I had :D

New one is going in...

As for the 3.73 ratio....unless you are shooting for monster HP, I think its a step in the wrong direction. I know HITman is taking that path, but he will be making more power and torque than you and me combined :D

Personally, I would pay for stickier tyres to reduce wheelspin and stay with higher gearing for better acceleration combined with traction :D
