660 cc / denso fuel pump but no AFC - whats the consequences?

[boost junkies]

my motor is fully ported from the intake manifold to the O2 housing, with the big 16G. i ran out of money from the engine build up and am very afraid of running the car on stock fuel. if i install the fuel pump and bigger injectors w/o the AFC what are the consequences? i am gonna buy an AFC but need a month or two to save up.....

you will be pig rich.

my suggestion would be install the fuel pump and keep the boost down.

since you dont have the pump yet rewire your stock pump and keep the boost down.

If you install the injs your idle will more than likely be horrible and waste a whole lot of fuel.

With that much fuel you will just choke the engine. It will run like crap. you will foul up your plug's and you could destroy the catalitic converter

Well it prolly wont even stay alive =) Anyhow theres really no reason to be scaird, its all how you drive. Just cause of what you may have been told or read somwhere shouldnt make you scaird to drive your car. If you have a rewired fuel pump you should be fine with 15psi on your turbo and setup on 91 octane....

But if you want your car to actually run, you must consider some form of fuel "control" for the injectors (also make sure to get a FPR)

Shooting flames out of your exhaust.

You need some kind of computer to correct the extra fuel.

have have 660 and gas was coming out the tail pipe until i got my fuel controller set.

I dont even see why your worried, I ran 12.6 on a 20g with 450's....you can run 16 psi all day if you have the fuel pump in.

At least get an adjustable fp regulator on it till you save for your piggyback. Those are big injectors ! I run 625cc on a super 20g an my AFC both high and low are in the neg side of things.

 

[ItsStockOfficer]

Huh? You should be low, and he will never need a AFPR with that fuel pump, ever.

so in conclusion just install the fuel pump and not the injectors. keep the boost at 9psi. and only install the injectors after i buy the S-AFC and install it.

19 psi? 15-16 psi all day long
