Questions !!!, i'm planing to turbo charge my 4AF engine would it be ok to use the standard carburator, if so how much PSI would be safe for it ? i'm only planning to run 3 psi for now would that be ok? is there anyone here who have done it before?
pressure box is a box built around the car, that equilizes the pressure around the carb so that the throttle shaft wont leak out pressure and that the float chamber get the same pressure.
If you dont pressurize the carbs, it wont work, fuel will just back out and leak out from the float chamber.
I'd say 5psi can be done, I'd keep the limit at 8 or 9psi with the stock parts.
