hero gear maybe?

It all depends on your power, where the charger lights, rpms you run and track conditions, there really isnt a cut and dry answer w/o all of the specs to go with it.

I run 6 33" sts's and run 1:1 gear with 4:10's and find myself need more gear at time due to lack of rpms. I have no problems power wise to spin that setup but I do break a ton of parts. I also have another customer running a CR that runs 3:73 gears, 1:1 gear and 35" tires and has no problems with power other then breaking his driveline. But his power is right at 1000hp right now so you need the umph to do it.

What is your hp?
What size EXACTLY is your turbo?
What RPMS do you run?
What kind of track dirt do you pull on?
What kind of sleds do you hook to?
 
It depends on dozens of things, some of which is driver ability,GOT SMOKE,:kick::hehe:
Most bdp mentioned above.

At least 4.88s, maybe 5:13s.
Figure out how you want to pull the sled, with low rpm TQ, or high rpm with less TQ.

So, you are going to pay for drivetrain parts, or pay for more engine.

But 4:10s are right in the middle of getting no where.

Any machine shop that can make gears. 2nd gear is the easier one to do you just need to figure out what gear ratio you need for sure
