So I am going to replace the rear differential and thought it would be a good time to do new gears as well. I have a Procharger SC and was unsure if 4.10s would be good or should I do 3.90s? Any help/advise woul dbe welcome.

3.90

I have 3.73, and I think 3.90 would be perfect for both performance and DD. Depends on you goals? Good luck

I am running a centri blower also, my car has 3.55s stock so if I was to do gears they would definately have to be 4.10s for me.

my power is in my sig...just switched from 3:73s to 4:10s and I freakin love it

I have a t/s with way more low end than the procharger...definitely go 4:10s

I would stay stock and put the money into other mods. You will just roast the tires off the car with taller gears. I would stick with 3.55 - 3.73

Running 3.73 right and tires stick really good. I have a hard time getting them to spin when I want to. Think I'll see how they do my first time at the track later this month.

With 4.10s, forget about 1st gear; it goes through it so quick.
373's are a good overall gear for racing and street. But good tires can still break loose fro a stop or slow speeds.
Either way, it will be more fun :)

I'd recommend 4.10's. I had 4.30's when n/a, stepped down to 3.73's for my current setup and will probably go to 4.10's down the road. I do have a 6 speed which makes the 1st gear not as short as the stock 5 speed but with the right suspension and some good drag radials you shouldn't have too hard of a timing hooking decently on the street. My car sticks MUCH better in 1st gear on the street now that I have installed an adjustable UCA and set my pinion angle to -2. It doesn't dead hook but it doesn't instantly send the tires up in smoke either.

What size rear tires do you run?

4.10s and a sticky tire

I needed shorter gears than 3:73s and I have a twinscrew

You will definitely want 4:10s with a centri...definitely...you just need tires with them

Regardless, you need sticky tires for any gear you choose

Had a procharger p1sc ho on this vehicle (before going turbo) with 4:10s on stock manual tranny, back then. 1st gear was tricky under boost, but the procharger generally enjoyed the rpms.

Thanks for the advise. I think I'll stay with the gears I have and save the money for future DR's. The car is not a daily driver but I don't want to make it a strictly drag car either. Mostly just going to be running Friday night grudge and mid-week open track nights.
