kinda dumb question but how do u use it with a manual car. I don't know anything about n20. do u turn it on at once or do u do it each time you shift. Anything else anybody thinks I should now it would be appreciated.

 

It depends on what kit you get. Usually the kit includes a WOT switch. It activates the system at wide open throttle. It is also recomended to get a window switch for M6's.

 

What a window switch does is turns on the nitrous at a certain RPM and then shuts it off at another (higher) RPM. This makes it so you most likely won't miss a shift and keep spraying past redline! This should also be used with a wide-open throttle switch.

 

so with that switch as long as you hit you shifts the nitrous keeps spraying as long as the rpms don't drop too much between shifts. is that sound right. Also can you nitrous if you have a turbo.

 

With the WOT switch, the system will quit spraying when you shift (as long as you let off the throttle when you shift....) The window switch will de-activate the system if you miss a shift, and over-rev it.... Both are safety items, and IMO should be on all M6 cars....
