Just curious as to how close the jets should be from the solenoid?

My guess is the closer the better right? Or does it not really matter a whole lot?

The 18" or so line that comes with most kit seems to be the preferred length.

Popular opinion is that he shorter the line, the harder it will hit. I don't have first hand experience to back that up though.

juiSSed is right. the shorter the lines the harder the kit will hit. make sure both lines are the same length. also the closer to the throttle body the harder it hits.

I thought I read about some guys having the line from the nitrous solenoid to the nozzle longer than the line that goes from the fuel solenoid to the nozzle. Reason being is that since the nitrous is around 1000psi and the fuel is around 60psi, the nitrous will get to the nozzle faster than the fuel will so in order for both fuel and nitrous to get to the nozzle at the same time, the nitrous line needs to be a tad longer, however I don't know how much longer, is there a rule of thumb?
This logic makes sense to me, but I'm new to nitrous. Would that make a difference?

I've heard that before also Chingon.

I've got a dry kit so I was just wondering, thanks guys.

may be something to that, but i have never seen a new kit that comes with different lenghts.

I bought a 4 foot line for the noid/nozzle since I have my n2o/purge noids mounted by the hoodlatch (and the nozzle in the bellows). I also have a 20 foot line from bottle/noid - takes a while to purge, heh.

The fuel line is the OE 18" NX one. I don't get any fuel bog when the nitrous hits, that's for sure, so I know they must both be hitting about the same time. It hits hard on the 100 shot at 1000psi.

~60psi fuel through 18", 1000psi n2o through 48"...

I don't think the length really matters all that much, physics says the 1000psi is always going to get there first, but I don't believe it's enough measureable time to make a difference in the hit... I'd think mounting the nozzle farther back in the intake tract is more likely to make a softer hit, as a larger window of "diluted mixture" hits the TB than vs. straight shot into the TB or direct port.

Umm dont most of the best systems just crack the fuel noid a bit ahead of the N20 one.....

Yeah but if you purge the nitrous line, that isn't the case...or is it?

What systems and how does this work?

The purge only clears the 20 foot line on my car from the bottle to the n2o solenoid (by the hood latch).

It doesn't clear the air from the 4 feet of line (again, on my car) between the n2o solenoid and the nozzle, which is the length I was referring to.

Most folks have shorter lines for both.

I didn't set the lines up that way intentionally for a softer hit, it was because I wanted the purge out the front air intake and that's where the n2o noid and purge noid needed to be mounted.

The fuel can open up earlier, by a fraction if the relay is switching the fuel on first. As it is, there is no difference in my experience. The NXL use different length lines per cylinder, figuritivly the rear would lean out at first hit, but it doesnt. Just a matter of accepting that the **** moves so fast, line length(within reason) doesnt matter. Now, solenoid to jet, closer harder I would believe.
