I currently have 3.42 and they are great on the street and spools turbo easily. I have another set of 3.42 and 3.23 available and I'm kinda thinking of trying the 3.23 to hook better on street. My street tires are 28.4" if it makes a difference. I can see truck going slower with 3.23s at the track but I think I'm going to stop trying to go faster already. Please post your opinion.

 

what rwhp u putting down ?

 

I wish I had that kind of power, I am going in the other direction for gears. I am actually considering 4.56, and I have 3.73 now. It is just too tall geared with the 20's, and I sort of want to keep the street tires on it.

What rpm are you going through the traps at? I really don't know if I would change to a taller gear for the street just because of traction. I would honestly detune it for street driving. Maybe mess with the tow/haul mode for street/strip. Im interested to see what route you go, and what the outcome is like.

 

Don't know. I run 12 psi on street and it traps 128 on this.

I can run 7 psi and hook but it feels slow. Plus on interstate on 80mph I turn 2600 and would like little better. Guess I've convinced myself to try them but wondering who uses them.

 

hey buddy,

i had 3.08's and 28" tall tire in FT before the new setup and loved it.
Still managed to go 141mph in the 1/4 with no traction (that was the small tires).
Got 33's and 3.55's now, so almost the same ratio.
I don't think you'll loose anything at the strip, but it sounds like you want them for the highway, go for it!

 

I changed my gears from 4.10s to 3.73s i hated goin 70mph and turn 2650 rpm with the 4l80e and only a 27.8" tire. Killed my fuel millage too

 

Looks like I'll be trying 3.23. Could always go back but will probably like them. Hello 120 in second gear. Lol

 

Are u puttin them in before next friday?

 

Hope so

 

Gears are in and I like them. Way less tire spin and boost comes in about 200 rpm faster. Overall boost on the same spring also went up 2 psi. Hopefully track times won't suffer too much but Even if they do drivability is better so I'll keep them.
