So then IYO a returnless car will never be able to run a direct port setup then.


1. It is possible to have a direct port dry system in a returnless fuel car if you can monitor proper nitrous pressure going into each cylinder so the EEC could increase the fuel pressure accordingly.
2. Of course, nitrous pressure is not constant while you are spraying(dropping while the nitrous oxide content getting lower also). Which means you will need extensive tuning to prevent you from going lean.
3. Now here is my question, why would you want to run the dry system? A wet system is much safer since you are not depending on the EEC to deliver the fuel for you.
4.Plus, NOS already makes the components for the returnless fuel system. Nitrous will spray right next to the fuel injectors(a special fitting goes in after the fuel rail) so you don't have to worry about puddling. Wouldn't that be easier??


No offense, but "quoted from someone who doesn't appear to know about this setup!"

1. Read up on the VCN-2000 kit! Then get back to me on all that. BTW - we're talking about RETURNLESS.
No FPR to use to raise fuel pressure. Increasing fuel output can only be controlled by programming the PCM or changing injector pulse width.
Also you don't need to control or "know" the amount going to each cylinder. Just the amount going through the solenoid valve - which is computer controlled and metered in this case! (one of "those" much superior part aspects!) The pressure will equalize in each individual port line.

Spraying in front of the MAF is a very piss poor way to try to accomplish this! Not only does it give erratic MAF readings which in themselves could destroy the engine (random lean spots), but it most likely will also put the readings well beyond normal limits. The PCM has a limited range of operations for the MAF to function in. (MAF transfer function) If it goes out of that range it will throw a CEL. Also it won't be able to command any more fuel for the extra airflow!
Also the ultra COLD nitrous charge will make matter much worse and make the readings even more erratic.

2. If the nitrous pressure dropped then it would run rich, not lean. If it "some how" raised the VCN kit would compensate automatically (like I said read up on it)
ANY Nitrous setup should be dyno tuned. Only a fool wouldn't IMO!

3. For all the reasons I just posted! Please re-read my last post on the numerous benefits plus not having to install an entire fuel system just to make a wet kit on a returnless car.

Much safer, using the PCM is "un-safe"??? Why is the PCM unreliable and not capable of controlling fuel? Better tell Ford their EEC-V setup is suspect. (drip, drip) Wonder if all of Ford vehicles have to switch to a stand alone fuel management setup for mod changes.

4. DOES NOT FIT. Plus it's not for returnless cars. (unless they released something in the last few days that's computer controlled) Also the NOSzle setup is a wet system not dry.
