Re:NX Ntercooler VS. Water to Air intercooler
the pvc works excellent and is very light weight. I painted it black so it looks like regular pipe. I have already researched water injection, water/methanol injection, propane injection, and alcohol injection. They all cool down the intake charge and help deter knock, but my problem with them is tuning them. I am trying to do everything right the first time.
Propane injection works as an octane booster, which ups 92 octane to 110 and cools the intake air. Problem is, [HOOBS PRESSURE SWITCH] how am I supposed to tune the propane from 5 psi to 30 psi of boost. You can't run the same amount of propane at 5 psi and at 30 psi. If you tune it for 5 psi, then you won't be shooting enough propane for 30psi and vice versa.
Alcohol and Methanol injection, works very well but starts costing money. This is HMT correct?
Water injection is cool but I don't have much room left under the hood. Yes water injection is the cheapest and will cool the intake charge. Problem is the plumbing and the big resevoir.
In a sense, you can run out of anything when spraying it into the engine for whatever reason; I am just trying to find out what works the best within reason of the pocket book. I don't have race gas on tap and don't plan on running it. And I am not running alcohol nor methanol because of the expense. Thats why I am trying to find out if an intercooler chiller is a good idea.

i was only giving you crap before
but seriously I would go with new eagle rods and lower your compression for the long term and not worry about the chiller. Your fmic should provide enough charge cooling.

This is HMT and spraying $40 worth of nitrous is not cost effective compared to injecting rubbing alchohol (Denentured Alchohol) which is $1.00 a bottle. Using water injection for a year straight everyday would equal the cost of one nitrous bottle.
As for it taking up too much room under the hood...
It doesn't take up any room at all if you mount the resivor in the back.

Re:NX Ntercooler VS. Water to Air intercooler
very interesting whitey, I may consider the water injection instead of the intercooler chiller.
Water is free, and the bigger the resevoir the longer the water will last you. The tuning will be the same for any other injection, I'll just have the water come on at a certain pressure and tune my fuel from there. It won't chill the air below 0 but it should bring it down below ambient with the efficient intercooler.
Does your water injection get your temps below ambient? Is it best to mount it before or after the intercooler?

Re:NX Ntercooler VS. Water to Air intercooler
It has to be mounted after, otherwise the water will just condense in the intercooler, and if the intercooler is heat soaked it will heat up the charge if the water is doing it's job. It's not realistic to aim for super-low charge temps with water injection, water takes space and at a certain point you'll lose power.

isopropyl alcohol = Denentured Alchohol (basically, don't make me own you with the chemistry)
