Hello Everybody!

I kinda understand that the more boost that I put into my 5m-ge the more fuel will need also but I don't understand how the fuel system is supposed to supply more fuel as it is getting more boost. Does the EFI system already make this a/f ratio or is there something else that has to be done to the car so that it will be getting a good a/f ratio?

I was up late last night thinking about all this kinda stuff and realized that there is alot that I don't know about turbochrging and wish to know them b4 I put one any where near my car.

After the compressed air comes through the turbo and then through the intercooler it is supposed to go into the engine. But how does it connect up, does it go straight up to the throttle body if so where does the air filter go?

Man you all must think I am dumb, oh well I just want some answers please!

Does anybody have a diagram of a turbo set up it would be greatly appreciated.

thanx

I highly suggest you purchase Corky Bell's book Maximum Boost to learn about turbocharger systems. If you're on a budget check out;

As far as the EFI question goes, yes the ECU does learn, but in a somewhat limited way. The most common way folks take care of the fuel issue is to use a rising rate fuel pressure regulator (RRFPR). The RRFPR basically increases the fuel pressure in proportion to the boost pressure. Basically by increasing the fuel pressure the cc's of the injector is increased under boost. It'll require a decent A/F and EGT gauge to get everything tuned right.

WOW thanx that explained alot!

Seems to be pretty straight forward.

How many average PSI can the stock 5m-ge fuel system take?

Aaron Garney's running 8-11 psi with a RRFPR (Rising Rate Fuel Pressure Regulator) and stock injectors, etc.

HTH.
