Not sure how I went out of bhp into whp in the post you quoted.
But anyway....you are completely wrong about something. The air from turbos and superchargers does not get sucked in by an engine. It is blown into the engine under load enough overcome atmopheric. Why do you think they call it boost? We are talking power here. So in turn we are talking WOT. You go wot on any supercharged or turbo car you will see positive manifold pressure. Boost is the common term. Boost happens because the turbo or supercharger is forcing air into the engine fatser than it can suck. Another term...force fed. The air is pressurized...if the engine was sucking more than the turbo or supercharger you would never see boost. Turbos and superchargers are the morst cost effective way to achieve. VE well beyond 100%. The ONLY time a turbo or supercharged equipped vehicle is sucking is at idle or part throtlle (loads under the threashold to create boost or overcome atmopheric pressuse)
There are NA motor than have been known to see boost...but it happens in motors built bananas by someone with the knowlegde and hundreds of thousands of dollars to do so.
A nitrous motor does not see above atmopheric pressure unless its built like the above example. The nitrous is still sucked in by the motor alone. Not blown into the. Chambers.
If you turn the hose on it builds up pressure, and forces the water out of the hose and onto the driveway. this is Force.... nitrous uses bottle pressure to force N20 into the combution chamber. Nitrous force is does not have anything to do with WOT, this why it requires a momentary switch to avoid spraying it outside of WOT and why in bigger shots it requires its own fuel maps, buecause it changes the amount of 02 induced. You can spray a car still idling, it isn't good at all for the motor, but you can physicly do it.This increase O2, not fuel, and usually leads to a huge mess. Friend did this on accident when he by passed a non-working by-pass valve.
Forced induction=forced fed induction(o2 charge)........ whether is Nitrous, turbo, or even electric s/cs. Hell you can even do it with a leaf blower.... which outside of the induction stream would do nothing but clean the motor, but when added to the intake piping.... creates positve pressure.
BHP is at the Crank, pre-drive train loss. WHP is after the drive tran loss and what real power you make at the wheels.
less the EVO motor, and MZ6 motors are literally bench racing with engine dynos in you discription?
The NA motors that make positive pressure are crazy. Got to love crazy vac pumped motors with big ass cams and shit..... really impressive stuff.
I can't say for 100% if the nitrous spray excess 0 atmosphere, but thats because we don't hook up boost gauges to our nitrous cars, less they are boosted+sprayed big turbo cars.
yes turbo motors make over 100% VE, because they have these power adders and are superb at doing so. making an all motor car do similar USUALLY requires things like high compression, ITBS, C16, and a shit load of timing. I'm not saying it is impossible, but the math of what is required to do so vs what you listed is hard to swallow.
