Why aren't 3.45 gears worth it in a L99? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

True. I have 3.91s and love em. I just have a hard time hooking from a dig. Going to get R888’s next

I have a 2010 ss camaro with 373's and forced induction. When i first changed from stock the 373's really woke the car up and made it a lot more fun to drive. Now that I'm forced induction it is seat of the pants. In my opinion it was the best bang for the buck when i did it. Anyone else with 2010 ss with 373's feel free to speak up but i love my set up.

Thanks all!

If I run a converter and 3.91s what tires can I daily on and still have traction?

I have a hard time getting traction when I launch it from a stop and I daily my car. Tires spin like crazy and I full suspension as well. lol Also, depends on the tires you have.

From what I have seen, If you flash your converter you will just spin at launch with any street tires. If you want a hard hit off the start, put a 100 HP Shot of nitrous on that beast and you will feel the torque increase for sure.

do you have to change the converter if you run 3.91 gears??? what is the reasoning to change to a different stall??? im wanting to do the same gears!!!!! and im an auto l99

LCPLPunk · 03-15-2018, 12:36 PM

Nope, no need to change the converter for gears.

The stall will raise the rpms your car can launch at from the 1800 to whatever you want it to be. For a daily driver I've heard a 3200 is what works best, 3600+ with a cam.

What you should do is look at a dyno sheet, and look at the power difference from 1800-3200, it's probably around 100 or so, so basically you have 100 more HP at the wheels when launching. (someone please correct me if I'm wrong)

I plan on running 3.45 gears on the street I will run a 28” tall tire but then at the track I will run a 26” tall tire to get the final gear ratio to 3.76 at the track but still have the 3.45 driving around
