Wat ik tot dusver voor reacties heb gekregen:
Just speculation, but I have heard others boosting to 15 psi (ruffly 2 atmospheres) that a supercharger will drain 40 hp at peak, but there are alot of variables. As for the wheel on the sup, i thing you should refer to how much air is being pushed (cfm) now by it and use it for a starting point, reduce it from there.... as for injectors, you can try over pressurizing the ones you have for more flow, I would use the basic rule of thumb of 1cc flow of an injector to 1hp, use that to gauge if you need to add ONE BIG injector to the mix of all the rest you have. I assume you would be using a stand alone ecu. Why wouldn't you start an exotic swap like this with a C20XE. duel overhead cam = more power. Are you using a centrifugal supercharger with intercooler?
What kind of SC are you running? Roots or whipple? Maybe even centrifugal? THE person to ask these kinds of questions is Tony D, I believe that his job entails industrial application of air compressors. The thing you have to remember though, the correlation between compression, flow, and compressor speed are not linear, and depending on the blower in question have different values as well as different efficiencies.
The Injector thing is a different idea entirely, it all depends on what your expectations are for horsepower and what SC you're running. Generally though MFG's shoot for about 80% duty cycle in their injectors (though some cars like the WRX Sti and Evo's are running pretty maxed out injectors from the factory) so you have a little room to grow, but not long before you'll need to upgrade. Luckily, turbo cars have bigger injectors and you can probably find Injectors from a turbo Supra (the us spec, I'm not sure if the euro car is US Or Japanese spec), RX-7, or in europe probably the C20 Turbo injectors and have it made.
