what I'm refering to is the SC is a direct drive system that is governed by the size of either the Crank pulley or SC drive pulley, this is not a Turbo which is not a direct drive system so pressure fluctuations can be devastating if timing and fuel maps are not operating in thier boost parameters, thus it's more important to have the boost gauge on turbocharged engine and not SC engines.

but I would find it more informative to know the air temperature of the air coming from the pressurized side of the SC, the IC water temp is also good but that's not what the engine is consuming so there will be a lag in information as to what temp the air is at while entering the cylinder.


It would also be nice if you could somehow tap into the knock sensor, and install one of MSD knock gauges.
