I know nitrous is better on hot days than blower cars, due to the "cooling" of the intake charge. But lets say you have a 85 temp day with 60% humidity, vs a 50 degree day and 10% humidity. Would a spray car change alot in e/t?

 

Nobody?

 

It will change by the correction percentage applied to the air/fuel mix that is inhaled naturally. The percentage of overall power produced by the nitrous system will have a effect. The change will be more dramatic with a lower output system as a higher percentage of the power comes from the air that enters the intake manifold. I've got bubkiss to give you info wise on an LTx motor, but a fairly hot carbureted 350-400 cu in small block will drop roughly 200 cfm when a bigshot plate comes on. This is 25%+ of the naturally aspirated airflow that disappears as the nitrous/fuel mix is forced into the intake manifold and takes its place. As you can imagine this kills the carburetor signal, but that's anotyher story. By the way you better have a bottle heater. If you hit the button on a 50 degree bottle you'll be pretty unhappy.

 

I kjnow you gotta have bottle preasure, but with everybody knowing blower car hates heat. Does it really matter with n20?

 

Just use both the blower and nitrous, that way you have all your bases covered

 

The difference would be negligible.
