manual/automatic with nos

[blue streak 00]

I heard someone say that running nos on a manual is dangerous because you can miss a shift and cause serious damage to your engine. Naturally, automatics are much safer since your transmission can't miss a shift. To run nos with a manual should you have something that shuts off the engine when the rpm's go past the redline?

if you miss a shift you got a good chance of blowing your engine but if you have a manual then you need a window switch that cuts the nitrous off not the engine if the rpms drop to low or to high i believe i have a auto so i am not real familiar but i am sure someone can clarify it better

Auto's are the preffered vehicles when running nos. But there are many ways to improve safty with a manual. I don't have n2o yet... And I stress yet!! But when I do get n2o the set up I will use is a wide open throttle switch along with window switch (rpm activated switch) and a master arm switch. Oh and it goes with out saying a fuel pressure safty switch. But just be careful and make sure you have it in gear before you mash the gas pedal. But with a window switch you should be pretty safe as far as mis shifts go but you never can be too sure about anything with n2o don't ya love it. :D

If I had a manual I would do the following:
First fuel pressure safety switch.
Second wide open throttle switch.
Third rpm activation switch (aka window).
Fourth button activation on the shifter handle.

Reasoning behind them all:
First, if fuel psi goes low then the nitrous will cut off.
Second, you never want to juice part throttle
Third, you would stay in a preset rpm range. You could set a max rpm the nitrous would activate at.
Fourth, If I missed a shift the fuel psi would be up so the fpss would not activate, wot might be met, rpm's might meet the window switch but the button activation would be the deciding factor.

If I had manual I would feel quite confident with this set up.

I thought about putting a separate button along with everything els I've listed. I thought about putting a button in the space right next to the fog light switch, (traction controll) since I don't have T.C. Therefore I would have to take my hand off the shift knob to spray and that would guarantee that I was in gear. But I was thinking that I might not have enough time to take my hand off the shift knob to hit the button when actually racing :D

I have considered spraying too. As one more safety feature I've thought about adding is a switch on the clutch. Hooked through like the neutral safety switch where it won't activate if the clutch isn't let all the way out.
