You’d actually be suprised to know that a lot of people (including old guys) are running spray as well as building engines for spray. The guy that fills my tank up in averill park has a 7sec car with a built (somthing over 700ci) engine that has a dual stage n20 setup. 1200hp without n20 and 2000 with it.
I love the extra 3mph trap I got with only a 50 shot. With this, I don’t have to run as much boost prolonging the life of the turbos and still making the same power. Not to mention, I am not always spraying so it would tecnically be less continuous strain on the engine.
