I have 4:10s what do I do?
Alright I have 4:10s and am, currently trapping what's in my sig. Now I may be getting a NOS 5177 kit and spraying a 100 shot. I'm at the top of 4th now. With the N2O I would have to shift into fifth. I know it's not good to spray 5th grar. So what are my options. Rev limit is at 6350 right now. Could I shut off the N20 at the end of 4th and then shift into 5th to cross the traps until I get my tires? I want to keep the 4.10s for NA. How much would that hurt my times?
I have a h/c setup with 4.11's and don't hit 5th gear either. You can trap about 125mph with a 6500 redline. If it is that big of an issue, switch to 3.73's. Oh, and think about a wet kit of some sort. JMO.
