Hey guys
I was reading and wondering
Has anyone done the rear axle mod?
If you put a larger gear in the rear axle you would have faster accel, but lower top speed.
Has N E one done this?

Also I was wondering
Has N E one tried a shift kit on the auto trany?
I think it's called a VB here.

So if I did both of these would my car be chirrping tires or just spin uncontrolably?
Is there a way to off set the rear axle so it would pull harder mid range?

 

Very confused person here!

1) you have fwd my friend

 

What does the valvebody recalibration do and why do I need a transmission cooler?
The Valvebody (VB) recalibration is a mod for your auto transmission that will give you quicker, firmer shifts (which eliminates the weak point in the auto tranny: switching between gears). Normally, the auto transmission is calibrated to give you nice, slow shifts so as to ephasize luxury over performance. With a recalibrated VB, your shifts will be quicker and harder thus giving you faster times on the track. In addition to the performance advantages, a recalibrated VB will exert less wear on the transmission. Slow shifts will put more wear on the transmission components. A recalibrated VB may allow your transmission to actually last longer. However, the recalibrated VB does require the use of a transmission cooler. This is because the faster, harder shifts will heat up the transmission fluid quicker. The VB mod is said to eliminate up to .4 seconds in the quarter mile. Check out Level 10 or MobileTek Racing for more information.

How would a change in the rear axle make it faster?
A higher numerical gear ratio (such as 4.11) compared to a lower numerical gear ratio (such as 2.73) provides faster acceleration but a lower maximum speed. It's a tradeoff.

I have no Idea the details of these questions I found them on the FAQ section. Just trying to get some clarification.
Your right jeff I was wondering that same thing too?
How would the rear axle make the car accel faster especially if its FWD?

 

it's probably not directed towards our cars

unless you decided to put the money into the zx engine, tranny, and rear end combo

 

There ~is~ a way to adjust how your tranny shifts, and it's quite simple. Just tighten the kickdown cable a little bit at a time and take it for a spin until you find a spot you like. It will make it hold gears longer and shift harder. My tranny was rebuilt and they modified the valve body to firm up the shifts, but it still shifted too soon for my liking, so I adjusted it to hold the gears a little longer. On a stock tranny you might be able to adjust it quite aways, but too much on mine and it shifts like it's going to rip the motor mounts out ! I can even get a 2nd-3rd chirp if I stuff my foot right into it, but it won't chirp into 2nd though unless I'm rounding a curve.

 

I think he means 1st gen??

-hec

 

I don't know, but the kickdown adjustment applies to any automatic. As for the "rear end", it's pretty irrelevant to any of us, fwd or rwd. I don't think there are any aftermarket ring gears for any old Max's. Now if it was a 1st gen wagon with a straight axle in it on leafs, you could swap in a truck rear end to get lower gears. IIRC, all 4 cyl 4x4's had 4:37 rear ends, and vg30 hardbody 4x4's have 4:11's. Not sure what the 2wd trucks have.

 

Sounds cool!
How does your car shift from 1st-2nd?
If I put mine in drive it will never drop back to 1st. After a complete stop it won't go to second it just stays in 3rd.
