Is a boost gauge only good for super an turbo chargers or does it work for nitrous also?

 

nope, nitrous is not forced induction.

 

thanks.. yea i wasnt sure if you consider nitrous forced induction or not and if the boost gauge would work..

 

+1. Boost is a measure positive absolute manifold pressure (opposite of vacuum). Nitrous doesn't compress the air to create higher pressure.

Now a wideband gauge may be useful for seeing the air/fuel ratio under spray, but not otherwise neither.

 

latemodelrestoration sells nitrous specific gauges.
