Intercooler modification

[Redlyne_mr2]

I still have my stock intercooler and it just isnt doing the job anymore....what im wondering is if I install some sort of water injection system will I dramtically increase the intercoolers efficiency? If I stick with the stock intercooler for my new turbo setup will I encouter heat soak and actually defeat the purpose of a better turbo even if I have the water injection...any advice would be appreciated

yeah if you use the mist type nozzles foud on acuras you should lowere the charge temp by a bit this is the type of system that skylines use and evos use it too

i think they sell kits for like 300 hundred bucks you get a tank two nozzles and a high flow pump, i would just go the junk yard and rip a washer reseviour of some car and get the Acura mister nozles though, good luck

I'd use Nitrous nozzles if your going to use water injection

will water injection give me the cooling I need when added to my intercooler or should I scrap the idea and buy an aftermarket i/c

[jdmakkord]

An aftermarket IC will be far more efficient compared to a stock unit. Let alone the aftermarket intercooler piping being superior as well.

Then you could always water cool the aftermarket intercooler!

[legendboy]

watercooling should solve your heat exchanging problems but an new intercooler is just so BLING

[turboMiata]

Water injection basically reduces the combuston temperature and pressure in the cylinder for the net effect of reducing detonation.

The intercooler is meant to increase air density. water injection and intercooling are related but not entirely the same thing.

btw, water injection is not meant to reduce heat soak of your intercooler. to reduce intercooler heat soak (assume air to air IC), there's products you can buy that sit in front of the IC that mist it with water.

if you go with water injection like Aquamist, it should be controlled by a sensor that can detect boost.

i rember awhile back SCC put water injection on to a focus. They used piping and nozzles from underground irrigation system... something you can find at home depot .. they also used a small plastic fuel tank as the water holder. ill see if i can dig up that issue

Most people use the windshield washe fluid tank. This is especially useful if your car has a washer fluid level sensor that warns you when it's becoming low.

I know a guy running Aquamist on the track and blew the engine because the fluid ran out and the car started detonating.

thats harsh....I dont want aquamist to draw the line between detonating and not detonating I just want to raise my stock intercoolers efficiency to run my new turbo with higher boost until I decide what final setup Im going to go with.

If you're going to make your own water injections system, make sure you have a good filtration system. I've seen a lot of people who've fabbed their own kits, but the systems never work cause the nozzles are always plugged.

Don't cheap out, get an intercooler!! This is mine. That way you will never have to worry about it ever again, well at least untill you hit 450WHP.

[Redlyne_mr2]

thats sooo rad hollywood...who makes that setup???Most of the aftermarket ic's for my car are ass so Im considering a trunk mounted setup...im just scared about haking up my car to do it....

[Ekliptix]

I'd just go aftermarket myself.

this guy went a little overkill i think:

dood, if you do go on to water injection, remember one thing:

water freezes at 0deg. i'd recommend 50% methanol mix to keep the lines from freezing up.

BTW, that guy that blew up his car was racing on a very hot day. If the ambient temps are low, your risk of detonation reduces too.

I'd go for a more efficient intercooler. Bigger is not always better. For example, people are putting RS4 intercoolers into S4 and they are disappointed in the results. That's because the bigger RS4 ICs are designed to be most efficient at 60kph or more.

HKS Type S imported from Japan. Expensive shit.

turboMiata is right somewhat that bigger is not allways better, but in my case the car fricken hauls and I have the biggest IC kit for SR's in the 500HP and under range. Yes I probly have more turbo lag becuase of it but who cares, the stock turbo is still at full boost at 3000ish RPM so....

A larger intercooler usually offers better effectiveness and a lower pressure drop. The downside is that the larger volume that needs to be pressurized can add to the lag of the system. Also note there are 2 types of intercoolers tube & fin, bar & plate. Tube and fin cools better, bar and plate holds pressure better.

[Redlyne_mr2]

will having longer ic piping generate more lag as well?....if you were to go with just a core what would you go with?

in one word, yes. but by how much it depends on your engine/turbo size, pipe diameter and other mystical factors beyond my understanding.

well that sucks ....turbo miata, hollywodd, would you guys ever cut a huge hole in your trunk to mount an intercooler? Keep in mind this car is not my daily driver and does not see temperatures below 15 degrees (not that that really matters), the trunk mount may be my best option
