With superchargers, we do not reach max boost until nearly redline. I was thinking about installing a 50 shot nitrous kit to spray on the lower rpm's where we lack the torque. Is there any nitrous controllers that will spray according to boost? For example, I only want the nitrous to at WOT up to 4psi of boost then turn off.

 

nevermind, I'm an idiot. I just rembered that boost on superchargers increase relative to RPMs. So I can just get a rpm switch that will stop spraying nitrous at around 5000rpm's.

 

But isnt it unsafe to spray in the lower RPMs?

 

only below like 2500 becuase you need the air to really be sucked into the cylinders quickly to prevent puddling.... but that only happens really at low rpm's on high shots like 125 and above.... so a 50 shot starting at around 2500-3000(prefered) rpm's should be good for you.. and have it cut off early becuase your A/F is going to be really screwed up when the boost kicks in hard... and the nitrous is going, and then cuts off..... so make SURE to get it tuned really well... and possibly have a special map made for it....(def. Recommended)
