Direct vs. Intake

[shaneyeend]

I was wondering the diffrence in direct port and intake injection systems? which is better, what they do thats diffrent, and how could either one help more? any help would be apreciated.

direct port is exactly what its called while a regular system sprays through ur intake piping. direct port is better but costs alot more. for messin around go with a regular system(wet). almost all if not all the ppl on this forum using nitrous probably use the intake style. jst incase ur wonderin the dif. between wet and dry, wet sprays nitrous + fuel into ur intake, dry is only nitrous. ppl say wet is safer.

yeah i know quite a bit about N2O bye now, (i'v asked about a million questions) any was so i don't under stand direct port? where do the nozzels mount? where does the rail mount? i was lookin at the prices its costs mike 150 more, that doesn't seem like to much more.

This is direct port. One nossle per cylinder. Very accurate distribution of nitrous and fuel to each cylinder. Overkill unless your running a 200+ hp shot.

A single nossle wet kit has only one nossle in the intake before the throttle body. The fuel/nitrous mixture is seperated in to the cylinders just like air normally is from the plenum. Great setup for under 200hp shots.

It all depends on your comfort level. Personally, on MY motor, I wouldn't run over a 100 without direct port, just because I have a lot of time and money vested I don't want something stupid to go wrong, puddle, and boom.

Get a nice intake manifold that's already tapped for DP

not ot change the topic

but i see that you put your fuel regulator before the fuel rail, and then i see some people do it after the fuel rail (on the return side) like stock

which is best, and how is your idle without the idle control solenoid using the mustang throttle body

I have no idle problems at all. Idles 750-900, 272's, no IAC, etc. Also, my reg is after the rail.. I'm not sure how you would setup a regulator before the rail. I guess you could allow on a certain pressure to bleed through, but then you'd be pumping it against an unregulated endpoint (the return line).
