Can anyone explain why.. It is said that using nitrous moves your torque curve down.
How is this done?
Why does it happen?
I'm just trying to learn to better understand nitrous and how it will effect my choice of:
rear gears, tire size and RPM range going through the traps..
This question have to do with the many other that I have asked in the past.
What can I expect my shift point to be at?
Are there any Camaro SS running 15 inch rims?
One question I jumped in on.
All of these questions have been coverd pretty well for me. With the help of everyone on this board I'm getting very close to finalizing my choice but I think I need to better understand how nitrous effects things.

I am pretty sure the reason is because you are getting more N2O past the valves and into the cylinder at a lower RPM than you are at a higher RPM; therefore N2O had more of an effect.

Re: Can anyone explain why.. I'm by no means a N2O expert but from what I've read you achieve peak torque the moment you hit the button. This is another reason multi-stage systems to get the most torque throughout the entire 1/4 <img src="gr_stretch.gif" border="0">

Re: Can anyone explain why.. It's because you can now make more power by far than the exhaust can get rid of so you become exhaust limited earlier. This is also why NOS specific motors have more exhaust duration than NA only. <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

Re: Can anyone explain why.. When you use nitrous, it "shoots" in your engine at a constant rate....no matter what rpm. So, the lower the rpm, the longer your engine will get more nitrous than at higher rpms.

Your peak torque # will be in the same place with or with out N20. A dyno graph of a car with and without N20 will have the same curves, in fact they will be exactly the same except, the N20 #'s will be greatly inflated. The more RPM you can get your car to achieve(without grenading <img src="gr_grin.gif" border="0"> )while using N20 the more it will extend the horsepower peak. Tire size & gear ratio are factors to be decided when you know how fast your car will go in the 1/4. You will want the car go through the lights as high in the RPM range as you feel comfortable with. If you have any more questions about N20 give me a call and I would be glad to answer them for you 972 278 1649. BTW, Tony this is not a sales pitch I'm just trying to help the guy out.

Re: Can anyone explain why.. Kechme
Thanks for the reply!
I'm going to have to see how the car runs when I get done. Right now the heads are in the shop getting a valve job (they already have been ported) At this time I'm installing a new cam 221/224 .558 .560 @114 I also am in the middle of installing my McLeod Twin. (There are a few other mods but I won't bore you). After I see what this all give me then I'm going to but a Denny's Nitrous ready drive shaft, and a 12 bolt (leaning toward a Strange) with a set of 4:10's , Detroit locker, 33 spine, 1350 yoke. 28 inch by 10.5 inch slick mounted on 15 by 10 rims. I'm thinking about doing like Joe Kizzire. I would get the rear is narrowed a total of 3 inches from stock... 1 1/2 inches from each side. Use Convo Pros 10 inch rim with 6 1/2 inch backspacing. All of this will have to be done by April 1st. So there is the plan I'm hoping this welcome together well. When I come up with a problem I just might call. If you have any to add let me know and thanks again for the help.

Re: Can anyone explain why.. With a single stage setup, the N2O has twice the time to enter the cylinder at 3000 RPM as it does at 6000 RPM, for example. You'll get about twice the N2O into the cylinder at 3000 as you would at 6000 since the nitrous is spraying at a steady state. Normally, if your shift points are say 6500 NA then you'll want them about 6000-6200 on the juice. The more you spray, the lower the best shift point becomes.
