Direct Port Dry has anyone here tried a custom dry direct port setup or have any links or info on any setup like this.
I know there are a lot of people who are using custom dry setups and injecting the fuel through the injectors rather then the solenoids.
any info or feedback would be appriciated.

One word... Fuel.
A system would need to be developed like the Ford Lighnting has. The system I have seen uses higher pressure fuel when the system is armed and at WOT. This lets the fuel system "dump" fuel through the injectors to go with the dry nitrous shot which is sprayed directly into the supercharger. It seems to work good for them with the supercharger. So I know it is possible, just not sure what the benefit would be.

THis is possible, with a large injector and a nice stand alone ECM setup...Ive seen GEN 7 DFI do this, ive seen FAST systems with this capability...I think Big Stuff 3 is even out there with the option...ITs really a trick setup and very pimp. There is a King of the Hill back 10.5 car with a 5 stage dry fogger on it. Of course it has 160+ lb/hr injectors though and one of those Engine management systems mentioned above...Thereis an LS1 in LA with 2 kit dry fogger on it. Keith Craft built it here in Dallas.

This is some good feed back,
Ya from what i heard the accel computer can do this.
I mean, it sounds so much safer and accurate to add the fuel through your injectors cause seriously, how many times have your injectors let you down compared to the fuel solenoids of a nitrous kit.
Definetly you would need a stand alone, this would not be possible on a stock ecm.
The reason i asked was cause everyone with this setup is basically the bad boys of nitrous, and it is all custom with standalone and the whole 9 yards.
From what i have read, it's either changing the duty cycle when the nirtous is armed or having the computer control aux injectors for when the nitrous is armed.

you could do it without a standalone too with aux injectors. You could use some type of cheap injector driver and set your duty cycle for XX size shot when activated. You could tune the AF via the driver and duty cycle for the size nitrous jets you have in the dry nozzles. You could get very creative with a little know how.

why couldn't you do it with an after market fuelsystem?? like an lt1 dry kit.. if you put a return system on the car vacuum operated regulator with the solenoid that spikesd the regulator?? we are running a 180 shot dry on an LT1 with 24 lb injectors through the stock system with a booster pump... when he spraysfuel pressure goes to 88 psi.. and he can very that with a jet in the vacuum line to the regulator..
a system like this would let you keep the stock pcm and just fool the injectors..
