Intercooler sprayers on fmic?

[Guest]

Has anyone logged the diff in temp with intercooler sprayers back to back with a fmic? Was thinking of wiring it through a oil pressure switch or similar to turn it on at 8psi or so then having it master switched via high boost switch.

Also is it worth mixing meth/water to spray on fmic?

You could also fit one of these Kemo Adjustable Time Switches (2sec-23min/$45ebay). They have an On switch and a separate Kill/Stop switch you could wire into an Empty Reservoir/Low Water Signal. (4sec spray at 8psi)

Not planning on spending over $15 on this not that serious lol. I wont be tuning it for water spray or anything silly just to keep it cool going through the twisties as thats when the temps climb.

You shouldnt need a pressure switch Clint, the G4 can do that for you. Just use a spare aux Output and set it to come on at a certain inlet temp, or boost level.

Duh didnt think of that that would be perfect. Worth doing in your experience?

It certainly wouldnt hurt. We do it on a couple of the circuit cars as on really warm days after a few laps the heat can cause inlet temps to rise. I havent done it on my own car so cant comment from personal experience sorry (so far my intercooler has proved efficient enough to do the job) but in my opinion its a good mod for not a lot of money spent.

Im just wondering if you could get it below ambient with water/meth sprayed on the cooler? That would make it well worth doing.

my car has the factory ra squirters on the apexi fmic and i rekon it makes a difference .

the outlet tank and pipes to tb feel pretty cold

I don\'t see spraying methanol at the intercooler working better than water

In fact it\'d almost be a bit naughty to drive along with methanol dripping onto the road? Would keep the intercooler clean though

I recall seeing temperature results of using sprayers, does joker perhaps have air temp gauges installed to inlet and outlet of intercooler?

[Guest]

I read on that reliable source the webs that meth mix worked better than water. Never looked into the science of it tbh.

[Roo]

Suppose a water/methanol mix wouldn\'t be as flammable. But if i was topping up a methanol container regualarly i think i\'d be more likely to go that bit further and run methanol injection for full effect

Evos have this from factory

Yes it works

Meth just evaporates way faster than water, the phase change is highly endothermic (although actually less than water, it just happens at a lower temperature) thus removing large amounts of heat from the intercooler

Yes, you can get below ambient by using evaporation of methanol.

Well no coz consumption would be uneconomic. Its not recommended to inject it greater than 50:50 anyway as then it becomes a whole lot more volatile i think.

Just water spray tho, not present on all models is it just RS I thought? I know they ran it on Gaz\'s silvia in the states to get away from the high temps where they were and sure they used water/meth.

Thats what I thought but didnt want to sound like an idiot without checking up first, and I dont know tricky science words I only learnt what I had to to get good marks at school rather than actually learning it to remember it to use later in life. :

I was looking at some nozzles on Monday on my run but they dont have a long enough base to use in my bumper and no locking nut to hold em in there. Bunnings needs a visit.
