Hey all. Was reading up on previous posts about the NX n-tercooler setup. Seems pretty effective, and for those of us who would like to say they have nitrous but dont wanna kill their motor (especially if its already experiencing boost) it seems like a good route to go. My only concern is turbo spiking. I talked to an STi owner w/ the setup and he loves it, but he said it does make his turbo spike a few psi. Not a big deal for him but for us 420a'ers it could mean serious problems since our motor cant take that much boost. Just wanted to get some opinions on it, whether or not any of u have it and if it makes ur turbo spike. I'd like to get it but if its just too risky then its probably not worth it.

Try the search fuction since we have discussed the risk vs benefits before.

nothing like driving with the windows down and the music low: i love hearing the turbo spool, swwwhhhttt!!!!
thanks for www.kaptainmyke.com for the sig hosting

god damn u people are annoying when u respond like that. I did search and i read up on it but i wanted to know if any of you actually had the setup and if it actually made ur turbo spike and if so how much?

for fuck's sake.. search.

if you did search, then youd know not to bother asking questions because its too risky and overall pointless thing to do.

The sprayer def works to lower your intake air temps, but I have never heard of it causing spiking issues..thats interesting. Only thing I can think of is that the colder charge to the motor is causing the boost to raise faster for some reason, and the wastegate boost controller can't react fast enough..just a random thought..But also, like said above, this is something that needs fuel compensation for, and I think would only be really useful for track only purposes, and used all the time. If you really want to lower your intake temps, get a more efficient intercooler..thats the best way out of it..And people, be nice

sorry , but like mentioned above this has been answered by people that have used it. Also like mentioned above its useless, especially for our cars. Unless you have some sort of standalone that can compensate for the denser air charge it will cause you to run lean. If you tunr and compensate for that? Then at the times you are not using it you will run Rich. Get the point?

For myself Imgoing with something that will cool the heat caused by the boost but not do it to the point of causing serious tunning issues. Something like a watter sprayer set up.

I know but im not some newb who doesnt search before they post. My specific question was whether or not any of you had SPIKING problems with it, not what u thought about it. It did not mention anything about spiking in any of the posts, hence why i posted. Just because a topic has been discussed on the board before doesnt mean every single thing about it was answered. Please read my posts more carefully for anyone who calls me a newb and telling me to search. Im sick and tired of fighting with people telling me to search after every post i make. If any of you find 'spiking' discussed in any other posts then u can tell me to search all you want. All im asking for is for someone who HAS the setup to leave feedback about it and whether or not they experience spiking problems. Why do we all have to be such assholes to each other? We're all DSM owners, so lose the attitudes, please....

BTW thank you GHETTORAID for giving me input, thats all i asked for. And as for you siueclipse, i did read the posts and there was actually a member or two that got 28whp out of it. Whether or not you think its worth it is your opinion, so chill out.

whoa calm down, I hope I didnt sound harsh.

what I was saying is that the spiking is a boost leak or management. Like I said factory turbos have built in systems to regulate that.

no you didnt, and i didnt mean to either. Im just tired of people that are so quick to yell at people and call them newbs and tell them to search when they dont even fully read the post.

the only problem is that you were asking a smaller "specific question" about a larger genreal issue that isn't favored/dosen't work. You cant expect someone to tell you what they think of a superchager belt squeack on the 420a, when there aint any working (although attempted) SC'ed 420a's.

understandable, and after reading about it through the search i never did really plan on buying it, but i was just curious if anyone had it and if they had spiking issues.

bah.. they are just asses trying to cover their asses.. hehe.

now if I remember this setup right.. it sprays N2O into the outside of the intercooler to cool it down (like a water sprayer)... So I can see how that could possibly cause a boost spike if it cooled down the air significantly very fast..
Maybe you'd be better off with a water sprayer.. cheaper to refil too

i don't see the intercooler sprayer as a huge power gain but rather a supporting mod. I've been looking into this and have found that co2 is much more useful for spraying on the outside of the intercooler. It is colder and a whole hell of a lot cheaper. The mod would help more w/ heat soaking issues that just an all out power gain.
