Nitrous and gearing?

[Texas~KR]

I'm gonna be racing 2-3 trucks at the track soon. One I've already beaten in Mexico. One I know I'll beat since they typically run mid to high 14's. But the other has run a very best of 13.7, with some low 14's.....
So, I'm concentrating on the last one. Studs won't happen anytime soon, so I'm wondering if you think it's a good idea to have a 50 shot readily available should I see him pull on me half way down the track? Do you think spraying this one time would hurt my non-studded motor?
I run my xtreme tune daily, and run it hard at times. Still going strong.
Will I gain much spraying without modifying the fuel system? Is there still fuel available for the mix?
I already have the kit, btw.

What about gearing? Is there anything that could help me slightly at the track, yet not affect my mpg's as a daily?

If you change gears there is no way to avoid a mpg loss....unless you also get a gear vendors od.
I dont think I would use nos on a non studded truck unless I had it lined up to get them put in right after.

[Texas~KR]

But if I chose to hit the button for the last 5 seconds of the 1/4, would there be fuel for it in my tune?

[Texas~KR]

No one sprays on the stock fuel system?

[Texas~KR]

Well, I put this together for about $200 with new parts.........








Hmmm, I think I'll start with a .030 and see what happens.

For what a shop would charge you to regear you would almost spend as much money as having studs installed...

you can spray up to a .086 jet on a stock fuel system assuming you fuel pump is healthy.

[Texas~KR]

Yea, I read about that, but I'm still on stock studs and just want a 2-3/10th gain in the 1/4. It wouldn't be a mod that I'd regularly use until I get studded.

What is the hp to jet size ratio? How much power difference between the .030 and .086?
