3.32 gears to 3.73 how much improvement

Sent from my iPhone using Tapatalk

you dont GAIN HP by changing gears in the rear end, your car will be quicker but you arent adding HP you are just putting the HP you already have to the road differently

Beware! It may seem like a less expensive way to make your car quicker, but there are longer term implications. If you make any mods in the future that actually increase horsepower it will be harder to get it to the road and you will be replacing rear tire more frequently. Also, evaluate the impact on the rest of the gear train. Will full throttle shifts put more stress on the transmission clutches with a higher gear? What will be the long term impact of running the engine at a different rpm? etc.

Increases torque at the rear axles…

He meant lower gear…

A differential with a lower numerical ratio / number, will decrease rear axle torque.😁

Conversely, a differential with a higher numerical ratio / number will increase rear axle torque.

These changes would have absolutely nothing to do with horsepower, which is produced by the engine during the conversion of the fuel to heat.

Horsepower, at the engine, is simply torque multiplied by engine rpm.

I don’t know if it is possible, but someone might desire to change the title of the thread if it is wrong(?), as it’s confusing…

changing from 3.23 to 3.73

Haha this may be a case of booze, and region. Kinda like pop and soda I guess… I was always taught low gears are the higher number, while high or “tall” gears are the cruiser gears… lower number…

Don’t mind me, I’m just here for the boobs.

Yes the term you’re using is idiomatic my friend..😀

Low gears, are sometimes associated with a lower vehicle speed.

But they use a higher numerical ratio.
Where higher numerical ratios, are then used to multiply torque.

For boobs, we will call the boob master…@random84

Take care!

Thanks for putting me in my place, again, Bruce! Haha

Happy fathers day ya cunts! Yes, I know that’s tomorrow, another idiomatic…😉

Jmo 3:23 to 3:73 isn't the end of the world but the difference should be noticeable.
Jmo 3:23 to 4:10 would be a big decision and need considerable thought In your application.
Jmo 3:23 good hwy, top speed, gas mileage gears.
Jmo 3:73 good for daily driver around town, good stop light launches, gonna lose gas mileage.
Jmo 4:10 great drag strip racing, not the best going cross country, really gonna lose gas mileage
Cuz you're gonna be running higher RPM's
Does that make sense?

These engines, with their simple roots blower, produce an abundance of of torque, at low engine rpm.

If you compound that engine torque, through the transmission (First Gear) and the rear differential ratio, you’re going to require a taller tire. This is all simple multiplication…

Since a taller tire reduces axle torque (here we divide the above by the tire radius) we must recognize that the additional rear axle torque we found, via using the higher numerical differential ratio, we are now going to attempt to kill by using the taller tire.

If the taller tire is not used, ‘Wheel Spin‘ will be worse,
than before the changing of the rear differential ratio.

3.23 is a good gear for a 6L90 car. If it isn’t fast enough add more power.

The reason the manual cars have 3.73 is due to TR6060 having less aggressive gearing.

I just thought of something NOOB might not know. Are you starting in 1st or 2nd gear? 1st will get you off the line quicker if you have traction. If you don't know you are starting in 2nd. There are numerous existing discussions that may tell you how to get to 1st. Do some research.
