turbo gearing I have 4.10 gears in my car right now and I have a lq4 turbo in my camaro not quite done yet but would it be better if I got 373, 342, or leave the 410 it's an auto and most of the time going to have 17 inch drag radials

Look at turbo Buicks - even the fastest stock suspension cars still use stock ratio 3.42 gears. Turbos build so much low end power, you don't need a low gear set like a 4.10.

I'm looking at possibly changing my ratios slightly. My A/R on my turbos is getting cranked up from a .63 to a .86.
I run a stock 3.42 cog, I'm looking to turn it down to a 3.33 or 3.23 to help the spool I'll be losing. Figure high 600's at the tire on pump and 850+ to the ground on race gas. I wonder the ratio change will be worth it or not.

Had 4.10's with a 6 in my 99 TA I had. Didn't build boost on the *** mount until like 3rd gear... could get a couple lbs in 1st, like 4 in 2nd, and could get 8 in 3rd.
Damn that's bad, did you ever try a diff gear in it, have headers? Was spooling the base T60 by 2400rpm and a GT70 by 2500rpm boosting nicely with both by 2800 and 3000 on a stock M6 car with MAC Y with 60lb motorons.

get 3.23's in a 6-speed car and 2.73 if its automatic. You will thank me later from the amount of MPH you pick up in the 1/8, 1/4 and just about any and everywhere!!! TRUST ME DO ITTTTTTTTT!!!!
