I haven't posted in a while (nitrous shortage), so here is the "Musty Plan" for a stock engine street beast:

Obviously, this is just a predictive model and in no way reflects real world results but it should be close. The key is using the progressive power application where the engine speed rises and torque falls. Most supercharger systems reflect similar results in power and peak torque, but not the broad torque curve possible with WoN nitrous systems.
Moreover, it shows how it's possible to run such a large amount of nitrous on a generally weak engine (internally) where most nitrous users have failed, thus praising superchargers as "safe". Unknowingly, they don't realize the huge amounts of sudden torque even on a much smaller shot can blast pistons and conrods to powdered bits. Like in this example:

This example uses a competitor's "Wheel Horsepower Rating" (more like horseSHIT), where the typical user blasts a "150 whp" shot of nitrous. This engine won't survive very long and I have yet to see one still running around. And even if it did blow, the owner probably wouldn't fess up to it.
More on the WHP rating: there is no magic behind claiming that a shot is measured at the wheels or at the crank. The only difference is taking out the friction loss variable of the drivetrain. In order to produce the WHP of 150 through a manual, you must flow enough nitrous to produce approximately 175 bhp worth of it. Simply put, our 'X' competitor just flows more nitrous initially fooling the average person into thinking that their systems are more efficient when they are not. I could easily claim that WoN can produce a 150 whp shot, when the theoretical value is 175 bhp. It's all psychological nonsense!
So yea, I'm hoping for a adding 170 WHP to my stock engined Musty. The power levels pretty much put it close but not dangerously close to the power limit. However, my engine is pretty seasoned and it is possible that it's age could promote conrod twist and aggravate any micro cracks if used too often. A lower torque level around 380 wheel torque would be a better choice for performance over a long life. Just something to think about when trying to push the limits of an aged engine that normally would hold a 450-500 wheel torque limit before failure when new.
