Intercooler Water Sprays

Spraying the intercooler manually before a run makes sense. With the luxury pack, Ive got 2 t/c buttons; one on the dash to the left of the steering above the fog lights and one on the bottom left of the ICC therefore I can convert the dash one to be a manual water sprayer.

I think having a thermo fan on the intercooler would negate any improvements by hindering air flow and power drain when its on.

A 4psi pressure switch might work but Im no expert so it might be effective after its needed like someone else has said.

How about a temp switch on the ic outlet side to turn on the sprayers?

Dont know the method but you need some mechanism in place to automagically turn on the ic sprayers during a power run especially with a manual.

You mean like the one from autospeed? I thought that would be a good idea but you would have to have an overide switch, as it was said earlier you dont want to start spraying and leak on to the track Would be a good idea for the street though

Hi Shane.

Its a bit hard to tell what you are referring to as youve quoted my whole reply. Are you saying the autospeed device works off a temp sensor? If so, can you give me a link, web site or retailer name to this so I can find out more.

Seems like the front runners are the boost pressure switch or temp switch with a manual override.

Can someone tell me where to get the Hobbs boost pressure switch from in Sydney?

Max, went to the autospeed link that you listed in your first post and to me it says that it monitors ic temp and comes with thermistors so im assuming it starts spraying when a certain temperature is reached. It might be worth a call to them to make sure.

Still think its easier and just as effective to hook it up to your washer bottle and us the wiper stalk to do the spraying.

I have bought a washer bottle, pump/motor, lots of 4mm pipe, T-pieces and joiners, one way air/water valve switch, fuse, wiring and sprayer nozzles. I am in the process of finding somwhere to mount the watter bottle in the engine bay.

We are also designing a PCB circut that will allow me to control the spray-time (2 to 7 secs) and non-spray-interval (.5 to 10 secs) with manual overide and voltage regulator.

I put the pump into a 20L water drum in the back of the ute, & I switch it manually using the traction control switch, this can only be done in the utes, as the traction control switch does nothing!

I have seen the traction control fitted to the Utes aftermarket, using Ford parts.

Good idea.

Ok my daul spray IC cooler is done Im sure the power is more smooth! The anti-syphon proved tricky. There is a nice spot for water bottle near the brake booster!

I read someone was using metho/water mix...?

Adding 10% metho to the mixture will dramaticallly increase the cooling effect of the water. The metho does several things:

A. It decreases the water's surface tension and makes the droplets stick better to the intercooler fins rather than flying off in the airflow

B. It lowers the temperature at which the water evaporates (effectively the flash point) which means that you are getting more effective flash evaporation... the principle that actually creates the cooling effect.

If you want to know more about this sort of crap, I refer to Homer Simpson who once contended that 'In this house we obey the laws of thermodynamics'.

Do a web search on 'latent heat of evaporation' and you will find endless reams of crap about the amount of energy required to convert water to gas. This is what you are trying to do when you spray the water on the intercooler. This large energy transfer in converting the water to vapour is what is sucking all the heat from the intercooler, not just the effect of putting cold water on the intercooler.

p.s. Dont use more than about 25% metho in your mixture as you would not want your water spray to become flammable (I suspect that would be bad).

got any pics?

Ordered a Kodak z740 Digital Cam the other day. Cant take pics till the mailman delivers it
