ESE's works engine tuner

[Peljhan]

I am wondering. If we have an engine with matching STAs let's say 30hp for each system (intake, transfers and exhaust) and we measure 30hp on a dyno.
Than we make-increase STA on one of the systems to 40hp. What would we measure teoretically?

[wobbly]

As long as everything in your sim is capable of achieving the 30 Hp of the STA prediction, depending upon the inertia of the vehicle components and the friction component, then you
will measure something like 14% less on a rear wheel Dynojet = 25.8RWHP.
EngMod calculates crank power - so if you now upgrade every part of the engine ( not just change the ports ) then the same applies to the new prediction.
Note the Exhaust STA is pretty much irrelevant ( except when using the duct exit radio button shortcut ), its the Blowdown that is highly important.
