Plumbing my nitrous kit

Post  Beast on September 19th 2010, 2:51 am

I'm trying to work out how I'm going to plumb up the fuel supply to my nitrous kit and I had an idea that I thought that I'd run by you guys. The fuel supply for my motor consists of an Aeromotive A1000 pump to a 13204 2 port reg with bypass. One port will obviously feed the carby, and I thought that the other could feed the fuel solenoid for the nitrous kit. I have been told that it is best to have separate supplies but I'm pretty sure that the pump is big enough to feed both. The major part of the question though is, does it work to have a regulator inline after another regulator? The nitrous kit supposedly has to run at 6 psi but I'm not sure what pressure the carby is going to want. (motor is in the build stage) If there is a differential, running one pressure will not work. Will the second reg be OK to deadhead or will it want a return, and if it does, can I "T" into the main return line?

Or am I on the wrong track, does everybody have a separate fuel cell, pump and reg for their nitrous?

1 pump for both regs.....some say it's dangerous but it's enough pressure supply for both in my opinion

If it's good enough for the pro nitrous guys in the ADRL I'm sure it's good enough here.

we used the holley regs for nitrous with a small return and magnafuel for the motor. the holley regs had much better repeatability but I'm sure the nitrous pros here will chime in on that.

part# reg.12-803

I noticed that the reg you suggested has no provision for a return, do you deadhead yours?

The guys that do use a return on your nitrous supply fuel line, do you run it all the way back to the tank or "T" into the main return for the motor fuel supply?

From what I understand from the SJ camp is that the return style has a more consistant fuel delivery that the deadhead style. The class champion in our main organization runs a Bennet 434 sbf with a SJ fogger and runs 5.0's at 3000lbs with the return style setup. He tells me that he makes so much more power now because it's not pig rich on the hit that is the reason he picked up so much. He runs the 29.5 tire and sixty foots like a 1.16 now. before he could never hit the tires as hard because it was rich and would lean out throughout the run.

If it make you feel better run a return but i think it a waste of money.

I wouldn't worry about the creep either.. It gives the fual a little boost to fill the jet and bars and by the time it's done this it's at the set pressure.. SJ

I don't use SJ but have seen the results of his customers. All I know is some fast cars in my organization run what he says to run and they have return style fuel systems.
