hi!
i was helping a friend this weekend on a 1991 SW20 turbo with a albrex centrifugal charger (simmilar to vortech) put in front of the turbo.
the engine is stock aside from the additional 50%water/50%alcohol injection and a fifth fuel injector (both controled by a unknown device). it also has unknown pistons.
the air route is through the AFM, charger, tiny toyota intercooler, stock turbo, another tiny stock IC, water + fuel injectors to the engine.
does anyone know what the limit of such a serial setup will be.
i guess it will end when the charger will limit the turbo flow. (the charger pressure actually dropped from 0.7 to 0.2bar at 6000 rpm. the turbo was making 1.3bar +-0.1bar waves
aside from making it hard to tune at pulsating boost levels ... what du you think about the limits of a setup like this?
does someone have experience with these setups?
i will share any info we have on this by e-mail (maybe someone has webspace?).
