Seperate fuel supply for Direct port Is it absolutley necessary to run a seperate fuel supply line from the tank to the fuel side of the system or will the end of the fuel rail work good enough? Is there a certain point (shot wise, fuel pressure wise) that this will be necessary. I saw that the NX and NOs kit offer jettings as small as 100-150 for a direct port. Any help is appreciated.

Re: Seperate fuel supply for Direct port I guess its not necessary but you will probably sacrifice some drivability without nitrous because of the increase in fuel pressure trying to feed both systems through a small fuel rail. Because you now have one pump supporting both the natural aspirated horsepower and the nitrous horsepower. With one pump you have to be supplying enough fuel pressure for both when you do spray. A stock pump definitely won't do it if you are running a very big shot. With a direct port you should do it. ARE has a killer TNT direct port kit with a seperate fuel system. I actually have 3 pumps on my car but thats something different altogether. I'm tired and sleepy and probably ain't explaining this too well so you might want to give Barry or Wade at ARE a call or drop me some more specific questions via e-mail.

Re: Seperate fuel supply for Direct port Intake will be here Friday and I'm going to get it ready for dyno tuning. No track times yet. Still trying to finish the car up.
Re: Seperate fuel supply for Direct port I am running a MagnaFlow 300 with my TNT Fogger. There is no way a stock pump can supply the Fogger and the normal fuel system. With N2O, you should not play around with not possibly suppling enough fuel.
