I took the info from a book on supercharger in the fuel injection section. They wrote thats its a good idea to use on low boost application . Also they point to the fact of using right sized injector, reprogramming the ECM, increasing the pulse width (if necessary) and increasing fuel pressure , by a manually set fuel pressure regulator or a rising rate fuel pressure regulator, installed inline with the stock regulator (and a higher pressure fuel pump).
Heres an extract of the book:
Increasing system fuel pressure as a fuction of boost pressure is a reasonable method of increasing fuel flow to accomodate boost pressure to about 9 psi. Fuel flow changes trhough a nozzle are proportionnal to the square root of the pressure change across the nozzle. A boost-pressure-powered (rising rate) fuel pressure regulator can be made to drive fuel pressure up rapidly, to keep pace with rising boost pressure......
....Proportionning fuel pressure to boost pressure maintains the timed nature of EFI, keeping fuel delivery proper relative to the air-mass rate of the flow.That make sense to me...and I'm wondering if this "add-on" will help in the tuning of the EFI and help keeping dangerous "lean condition" away.
Also are these thing are reliable in itself?
Hudini, if in their kit the use of this device help keep the car 50 states legal, its a good idea on my side of the border to use it...If is there a thing I dont want me to happen is being obligated , in a near future du to "new smog regulation", to keep my car off the street. If my setup can be more efficient "pollution wise" than a stock 2.8, I think I 'm safe to think to be able to keep the car on the street...
