Talk to me, Gears?

[02GTKB]

I want some advice from those who have a similar setup as mine. I run the stock gears now, but what I am wanting if it is possible to get that quicker 0-150mph. I will obviously not go near 200mph. I feel 4.10s are too steep, maybe 3.73? My setup is in my signature. Looking for that lower end feel

I went 373 with a 305 drag radials, I wish I went 410.

With a 315 NT05r a 4.10 gear would be a good choice because of the height of the tire. I run a slightly shorter tire with 3.73's and am happy, but would want a 4.10 if I had NT555r or NT05r.

3.73 will get you to 150 mph with a 27.7" tire (285/35-20) at ~7,000 rpm in 4th. 4.10 will drop that 4th gear top speed to something around 135 mph. A shorter tire will drop both those speeds and a taller tire will extend them.

Dude no offense but this has been discussed MANY times.
4.10 and 305/315 R-compound is my suggestion and I've had both 3.73 and 4.10.
With a 0.50 6th and taller 20" rear tire there is no reason to fear the gear.
4.10 and 315/35/20 is 2000rpm at 80mph so no rational for less gear.

Reread your sig, not sure on your power, but we run same tire.
I was just datalogging today and 6900rpm was 143mph roughly.
I'm setting mine up for drag racing, but this combo is awesome from 50-150 on the street.
If you want more chance hooking up from lower roll speeds, consider 3.73 but if you're rolling from 40+ I still say 4.10.
Car will feel much better off boost also.
Run 26-28psi and suspension in normal not stiff.

Thanks guys, I datalog an 08 with my old 2.8 Kb and he has 4.11s and it just seems to much imo..80mph or more just seems it stops pulling or something.

An '08 has a bit different transmission gearing from a 13-14 and not really an apples and oranges comparison.

Yea I figured, but down low his is for sure quicker than mine. My car 80+ feels the pull where his dies out. I want both worlds I guess guys haha

That's my set up with same rpm at 80mph. The taller MT's actually make my 4.10 around 3.90. If I'm rolling hard I'm off the gas by 135mph which is just about tickling a bit below redline.
