What is the best gears for turbo application to keep the turbo spooling, 3.05's, 3.27's, 3.31's or 3.55's, thanks?
Best gears for turbo application?

Auto car or Stick ? 3.27's are usually the gear of choice for optimum performance. The whole idea is to put a good load on the motor to spin the turbo good at low RPM.
T-56, 6 speed, 03 Cobra Transmission.
3.55s
what size turbo?
3.27
70-76mm do they make that? Just throwing out some idea for future mods, thanks again.
most people run a 3.55 for a street/strip combo. The large frame turbo cars will run 3.08's etc.
3.27's.
also the longer gearing will help get a more useable rpm/mph ratio.

I guess I will put stock 3.27's back in when I get my turbo.

3.27 for sure
From what I heard, taller gear is better for Centrifugal blower because it keeps the rpm up where the power band is. As for turbo, the engine need to loaded up to keep the turbo spooling so lower gear is best for the application.
I have a single 76mm, with a T56, and 3:73's. So am I to understand that the 3:73's are actually hurting my cars capability? From what I am gathering...low gear is better for turbo spool? So should I go with 3:55s or 3:27s?
Still have the stocker, use it. Everyone seems to think 3.27's is a better choice...
3.73s are too much and are hurting your cars performance. Try atleast a 3.31 or 3.27 with the 6-speed and you'll be much happier. You don't need to run 4.10s like the n/a, nitrous or blower guys for better performance.
They are. I'm running 3.31s but I also have a 28" tall tire when I'm at the track. Even still I'm thinking about going down to atleast a 3.27 to see if it does even better.
i went from 4.10's to 3.27's and it was like i added 100 hp, much much more fun on the street.
That is very interesting. I never know that.
How about 3.05's?
