Anyone ever boost reference a fp regulator?

I picked up a n20 kit for efi and was wondering if i could do this with the controller to richen it up. I only want to run a small shot 100 or less most likely, less. I know i need to jet accordingly also. I was just wondering if it would work to modify the regulator too.

 

are you fuel injected?
are you refereing the to nos dry kit?
what controler are you refering to?
if you are fuel injected and useing the nos dry kit then it should work. it uses some nitrous pressure on top of the fuel press regulator to bump the fuel press to compensate for the nitrous being added to the motor.

 

No its carbd. But the kit is a dry kit. A ZEX to be more specific.

 

The DRY kits are usually made for fuel injection.. The only way i could see to run it with a carb would be to richen the rear barrels of the carb excessively rich. Then make sure the spray only came on at wide open throttle. Granted it would run rich without the spray but you would be safe to run the spray this way. You will need some sort of Air fuel gauge to get this rite. (or take a chance). If i were tuning this scenario i would start with the smallest jets and work my way up till i got it rite.

 

Thanks man i figured you may use a regulator like that. I was curious if the f.p. reg could help at all? I figure it cant help much but would it be affective at all?

 

I do use a boost referenced regulator, But mine is a wet kit and a separate fuel system for the SPRAY. We use one of the ZEX dry kits but its on a fulie car and it works great. If i'm reading you correctly you want to increase fuel pressure to the carb to make it run richer for the Spray. I don't believe this would work. The only way i see would be to richen the rear of the carb.

 

boost referencing a carb isn't going to help on a carb'd "NA" motor. First off, forgive me, but how are you going to pressurize the boost reference port if you aren't making any boost in the intake? 2nd off, all it does is put more fuel pressure on the line--it won't increase the amount of fuel in the bowl and it won't increase the amount of fuel flowing through the main jets. They'll only flow so much fuel based on the amount of air flowing across the venturi and the pressure of the air going into the bowl vents.

 

Not the carb the fuel regulator. Like in a fuel injected car. Use the n2o line with a t on the regulator the other spray at the carb. When the regulator is pressurized thefuel pressure will go up.

 

gonna go boom!

 

Have some faith brother.

 

Still not going to richen it up any. Besides I don't know if the diaphragm will like 900+ psi on it. Maybe I am not understanding it correctly.

Best bet is to get the "right" kit. Or build the motor to run without the juice. Lasts longer that way.

 

It does ok without it. I just got the kit and wanted to try it. The pressure regulator is a question also. A fuel injected one will work but im just not sure about mine. Small pressure increases will enricehn it slightly i know.

 

Ill give you a KILLER deal in my ZEX kit...

 

I got a zex kit. I needs to sell it i suppose since i cant do anything with it. Id kind of like to have that stuff you got but i need other stuff now.

 

cant you buy a fuel solenoid and make it for a carb?
