Much better distribution compared to many/most wet DP kits that mount a protruding nozzle into the runner and attemp to spray towards the intake valve; whereas, the dry nozzle hits the intake perfectly. The wet nozzle is done at different spots in the runner depending on who does the intake, along with some other restrictions. The airflow dynamics are upset with this protrusion, not very Volumetric Efficiant compared to the non protruding dry nozzles.Robert

it will definitely effect performance, any distiburance in airflow will effect efficiency. If you think about it this way, why does anyone port heads and intake. Other then increasing volume it smooths out the path the air takes causing less resistance. same rule applies with a nozzle tapped into an intake The idea is ALWAYS to smooth out the incoming air

I highly doubt that you will see much of a difference. You are making your own incoming air charge through the nitrous nozzle - the engine isn't really going to care about the small effects of a nozzle in the runner.
I ran a NOS nozzle system (this system had no airflow disturbance as the nozzle is located under the injector) back to back with a normal wet direct port system with a plumbed intake (same Ls6 intake), and noticed NO difference N/A on the dyno and NO difference on the juice with the same nitrous jet size. The only benefit to the standard plumbed intake system was that I could jet it higher due to the reduced nitrous flow on the nozzle system. The systems TRAPPED THE SAME MPH with the same nitrous jets.
I'd like to see some real 1/4 mile mph numbers with this wet vs. dry crap. I'd even doubt that most of the people arguing this point have actually compared both in a controlled environment or on the any track for that matter.

I think your missing the point on all fronts. From your argument blue printing and balancing a motor is not needed cause you wont see a difference because you just jet up. It's the combined sum of all mods. if you don't care, then that's fine, but the fact remains in the performance world that every, esp in the pro racing, advantage you can have will help in the overall hp department. You won't find any pros running a NOZZLE kit either. The wet vs dry and which will produce more power, well you've missed the boat there also. If you inject X amount of nitrous, wet or dry and have the same a/f timing and the such, you will have the same peak power and torque, basic physics. The real benefits of the dry hit are the safety and ease of use, along with the developing DP dry that seems to have an edge in all departments. I will be doing some testing in the near future and my dollar says the DP Dry will have a better performance curve IE: better Volumetric efficiency, closer EGTs and a/f per cylinder, and will this produce more power/torque, we think so. Now will non protruding nozzles help, sure will. Check what the big time racers do and are doing and have been doing, not your average street guy like us, and you will surely see all the small things can add up to one big thing. By the way, comparing two non efficient systems really proves nothing.

Please call Gene Fulton and tell him that his 6 second nitrous setups are junk.

Very, very nice setup. I do have one question/comment. I noticed the hard 90 coming off the solenoid to the dist block. Now from what I have been told, hard 90's in a nitrous kit are a no no. I have always heard that if using a 90 a full flow type 90 is ok, but no hard 90's. Obviouslly the person who did this knows what they are doing, again very nice setup. Not trying to take away from it at all.

I have some new finished DP Dry plumbing pics, and will try to get them up soon so you guys can let me know how it turned out. Of course I think it's pretty cool? Though I may just wait until the entire engine bay is done, which is totally made over from prior pictures. Thanks for the nice comments, as it means something to me, for sure, coming from my nitrous peers and buddies.

I agree. Someday when I step up to a real setup, that is the only way I will go. Probably end up doing a sheet metal intake like that big boy in the other thread at the same time, unless the Et carb style intake is out and avaiable right from ET port matched to work with my 240 heads, in that case, it may get the nod
