Well I dont reeally take the car to the track much. But if I do race from a dig, I dont want to get my self handed to me. But the thought of whipping anything from 60-140mph sounds good. So I guess something for around town and killing vipers and bikes on the highway. Its also a M6 car.
Also 9 inch or 12 bolt. Thats were I'm stuck right now. Thanks
Oh and I sold my Z06 last night so I'm kind of sad. Need to get my car going again.

You don't need more input, if you are 6spd you run something between 3.30-3.60, if you are automatic and care more about street run something in the 2.7-3.0. If you are auto and care more about the track gear it so you cross the line in 3rd just past your peak power.

I'm so glad yall are talking about this. I was curious too. I'm about to convert from a NO2 TNT 150HP kit to a turbo kit within the next 4 months. I have 3.73's in a Moser 12-bolt now. Sounds like I need to try the gears I have now and see how they work with the turbo kit. I'll keep yall posted.

I would disagree for the low street ratios..
My choices would be around 3.42 as perfect in stick or auto. 3.73 in m6 is still fine.
3.73 in track car auto is still fine.
This low numerical gear stuff seems to be urban legend .Go search the old boosted lists.There are tons of m6 cars that are running great times with 3.73 and even 4.10 gears. There are lots of auto guys with 3.73 gears.,Heck JM our resident TT aps 402 car did high 9s at near 140 with 4.10s and his 4l80e.
So your theory is he would have done low 9s with maybe 2.73 or 3.08s???
If the car can't make boost because of gearing then add lingenfelter two step/antilag box.This would help even on autos..or possibly small shots of nitrous.
And you don't always want the turbos to come out too strong off the line anyway.
Around town anything under three seems terribly doggy to me. Even with a bigger engine. Maybe on a 427 or bigger and you are not going to get much better traction with those 2.73s or 3.08s. You want to gear so you can go thru the traps in third on auto and fourth on stick to save that extra shift mostly. On a street car not very important at all.
That said am going with 3.54 gears and Dana 60. 9 inch would be my second choice.
That new m9 looks really cool.
And would welcome some real proof on this lower gear legend but the boosted lists pretty much tell the tale. And as said off boost anything under 3.0 is just horrible to me around town.
Now if you are building the car for bonneville salt flats welll maybe these under 3.0 ratios.
And who really needs to push their car past 200mph..??
And whats the update on your car there Kwikkar. Might send my turbos to same place in january or so to make sure have them back in summer but your car seems to be taking forever..??

i just run the ratio that i need to run based on the rest of the set up.
you always want to run the most gear possible from a mathematical standpoint
guys going fast with a lot of rear gear though simply must either be...
-doing it on et and not on mph
-running large rear tires that negate the high gear
-spinning the motor extremely high
i had to pull out my 3.42s cuz of my mph requirement, to stay under 6500 max rpm, and because i did not run a large back tire.
