NX Intercooler

[4G63Spyder]

Just in case you've never heard of it/seen it used...I want to say this is one badass modification and definitely worth every penny!

I installed my own, with no nitrous experience before...it's actually very simple, just follow the instructions in the book. If you can install a car stereo, you can do this, trust me. My only suggestion different from the book...get some long zipties to attach it to your FMIC...and use like six of em so it doesn't move around.

I had the following mods when I put it up on the dyno: Greddy Intake, Greddy 18G, Greddy FMIC with hard pipes, 2.5" custom cat-back, boost control solonoid restrictor removed, and of course, the sprayer. Stock boost control, stock injectors, stock almost everything else.

First run without spray: 229 whp, 220 ft/lbs
Second run with spray: 273 whp, 266 ft/lbs

WOW! All this while still running rich (10:1) on a mostly stock setup.

what boost were you running?

[blageo23]

Stock boost control, stock injectors, stock almost everything else.
HMMMM I wonder... HAHA. Did you get the little circle one? or is that the "Snake" one?

The only thing I don't buy with these and their associated dyno sheets is that who's saying that the nitrous isn't being ingested by the engine which is helping increased the power gains? I guess I'd have to see the before and after intake temps to even begin to make a decent opinion.

[4G63Spyder]

Well, watching the video, it is plain to see that yes, there is some nitrous being sucked into the intake...however, I was still running rich on the second run...and I was running 18 psi! It is the circle (more like oval) sprayer...

[scheides]

I don't know....if you're going to take the time to run all that nitrous, why not just put it straight into the intake, where it belongs? Why not run water/alcohol injection if you want lower intake temps? it's cheaper and less volatle.

Still, cool results. Got any dyno sheets for that? At 273whp, your injectors must be at about 110%, eh?

[4G63Spyder]

not sure...no way for me to find out (no datalogging). I'll see if I can post the dyno sheet later...

Going to get 550's later on...just need the $

[slowbubblecar]

it is odd to buy a nx kit and bigger turbo before buying injectors IMO.

[sleepydsm]

Isn't he talking about the NX Intercooler Sprayer kit? How could that possibly be dangerous?

[CVD]

Because the intake eats an unknown quantity of the nitrous sprayed on the intercooler. Although I wouldnt exactly call it very "dangerous" and I dont think anyone else here did either.
