X-Charger, Gears, and Rims

I plan on gettin a Hi-po (2.8) X-Charger supercharger, Gears, Detriot True Trac, and 20'' Foose Nitrous rims.

At first, my thoughts were that i should get 4.10 gears but after a lot of reading i see a lot of supercharged Stangs with 3.73's. But since i'm geting 20'' rims and taller tires i should probably go with 4.10's



Well I've decided to go with Toyo Proxes S/T 255/40/20 and 275/40/20 which is 28.6 inches tall (rear).

Therefore, according to the tire size and gear ratio chart (posted at the bottom of this post), if i get 4:10s it'll actually feel like 3.88 (Please correct me if i'm wrong) and if i get 3:90s it'll actually feel like 3.71.

Because of this, i'm kinda leaning toward getting 3:90s along with Detroit True Trac. Does anyone have any ideas of why i should go with 4:10s instead? Keep in mind that my Stang is going to be a road warrior with an X-Charger.

Any little feedback will be appreciated!



Here's the cut & paste of 28HopUp's tire size and gear ratio chart:

3.31:1 with 27" tires = 3.3100:1
3.31:1 with 26" tires = 3.4373:1
3.31:1 with 28" tires = 3.1917:1

3.55:1 with 27" tires = 3.5500:1
3.55:1 with 26" tires = 3.6865:1
3.55:1 with 28" tires = 3.4232:1

3.73:1 with 27" tires = 3.7300:1
3.73:1 with 26" tires = 3.8734:1
3.73:1 with 28" tires = 3.5967:1

3.90:1 with 27" tires = 3.9000:1
3.90:1 with 26" tires = 4.0500:1
3.90:1 with 28" tires = 3.7607:1

4.10:1 with 27" tires = 4.1000:1
4.10:1 with 26" tires = 4.2576:1
4.10:1 with 28" tires = 3.9535:1

4.30:1 with 27" tires = 4.3000:1
4.30:1 with 26" tires = 4.4653:1
4.30:1 with 28" tires = 4.1464:1

I feel ya...I'm saving up right now and won't be buyin this stuff until next year.

But does n e one have any answers to my question?

Yea, that's true but i'm getting 20'' rims with 28.6 inch tires.

I've ound out that they don't make 3:90s for the V6s 7.5 rear. Just 3.73 and 4.10.
d yea, i've heard the same thing about F/I cars most of them don't have 20'' rims and 28.6 inch tires

Gotcha! and thanx!
