Im not a fan of the way its plumbed. I would replumb it. On high horsepower applications you can not beat the directport. Unless you have sometype of aftermarket computer it is the only way to individaul tune each cylinder.

How much are you looking to spray?

I dont see what exactly makes it no good, but the line length is way out of whack. Front lines are are least doubled that of the rear and that does not make for a very sound system. We offer dual dry shots through nozzles, plates or direct ports. Let me know if i can help you out

i guess i can point the finger at me cause i did not research this more i call a few sponsors and not one said i could run it with two sides.

i am looking to spray 200 to 300 what ever it takes to get what i want.

sorry for rambling on just a little mad at the fact i spend so much money and then get told it is not going to work right.

This would have been more idea.

However What you have will probley work. Put it on and watch the plugs and see.

Waist of time if you can not adjust the fuel supply to each cylinder. Defeats the purpose of having a directport. Ofcourse we have already discussed this one..

So Ill move on....

I like technical discussions so I'll bite. My question is when you flow a wet direct port what's the most critical unavoidable area? I have a point to this I promise and I'm not trying to make anyone look dumb, but there is a flaw in this train of thought that I'd like to point out.

I think there is the potential for a momentary spike in the front 2 cyl.'s. I think it would be minimal though. It looks like a pretty nice setup.

Like I said in the past, you aren't needing to individually tune cylinders n/a, so why would you with a DP, you won't, because nitrous flows as equal as air. If you had any real experience with a Dry DP, you would know that the cylinder temps (EGTS) are more equal than most tuned Wet DP hits. For those reading along, the need for individual cylinder tuning on a wet is because of the way fuel is delivered unevenly by the fuel system in the DP wet hit itself. The DP Dry gets a nice even fuel supply via the injectors, so no real need to individual tune cylinders unless going real big, and NHRA bound. Man some of these guys need to join the new tech world of dry and leave the 40 year old tech of the wet carb style systems to the old guys whom don't want to understand the computer cars. Of course we have already discussed this before and the implication that some schooled someone else, as we can all see, is in reality back wards. You can take a horse to water, but you can't make him drink, applies here for sure. Blinders are on like a mule, lol, nothing personal, but my god, the little jabs never stop Scott.

By the way, a 300rwhp shot down the neck in front of the MAF works perfectly, with absolutely no need for individual cylinder tuning, so why would not a DP Dry work as well or better?

Ok...Back to the OP's question. All the lines from the distribution block should as equal length as possible otherwise you'll have lean/rich conditions per cylinder that you can't monitor even with a wideband.

Look at my Dry DP thread, there is no additional set of injectors. The dry hit is much, much easier to tune. It's mostly misinformation out there concerning the dry hits in general. Now that Racetronics has 80lb injectors that work with the Stock PCM, the sky is the limit concerning the size hit for the dry shots ( low/high impedance). Also, no supplemental fuel system needed, isn't that Sweet. Just upgrade your in tank, and there are kits for this that support 1000rwhp with no other mods, just the in tank system. Also, no watered down fuel mix from the stand alone mixed with reg tank gas, you can race gas in the main tank, so much easier. Check my web for tuning the dry ( a write up on the Interface coming soon) and fuel system upgrades. Really, there is no need anymore to go wet in any form, just old technology. Though, if you like it and understand it better, for the time being, then that's cool too.

For the original poster, having different line lengths on a dry hit is much less of a problem. Why? Well with the very high pressure of n2o it will still get to the cylinders pretty equally, whereas, the fuel (wet) will no flow so even because of such a low pressure, just can't compensate. think about it, 1050psi compared to 7/8psi or 58psi, which will overcome better?

Here's a 3 stg Dry: 1 stage DP Dry and 2-Stage Dry Plate kit. This will be what my DP Dry will morph into soon. For now it's stg 1 DP Dry, Stg 2 nozzles, stg 3 nozzles.

Good choice. Did you see the thread with my DP Dry in it?
