intercooler sprayer

[Stott69]

So Im going to use my secondary windscreen washer as a intercooler sprayer. But while testing to find an ideal mount for the sprayer I found that once primed the system would gravity feed and empty the tank. Has any one got any simple ideas I could use to fix this?

[Adoom]

The best way that I can think of to do it would be some kind of sprung check valve. With only enough spring pressure to prevent the siphoning, but the pressure from turning the pump on will open the valve.

Fish tank stuff maybe?

Or make an air leak, with a T and a one way air valve, to break the siphon.... You would loose the water already in the pipe though.

Or you need more up-hill pipe than you have down-hill pipe. You might artificially create more up-hill pipe by using bigger bore pipe for the up-hill sections.

most factory headlight squirters have a check valve in them

ended up going back to p'a'p and scoring one. Just need to wire the pump to the switch

Slightly off topic - but how effective is an intercooler water sprayer? When would you use it? Obviously not at the drags as any water on the track will get you in trouble...

[Mr Ree]

At the track, either manually, or by way of a timer.

I have mine wired into the rear windscreen sprayer, and I just give it a twist for 10 seconds or so as I go down the back straight.

Its not really beneficial unless you are driving at WOT for extended periods.

Im using the secondary washer bottle, also rewiring it (with a P'a'P plug) back to my steering wheel button. As for use, Ill look into running a temp sensor on the intake.

Never noticed any difference tbh. Might help if you have a really inefficient intercooler. I was running up to 25psi and even on STM's dyno (which can supposedly measure the difference in power from the alternator load on the engine when the headlights are turned on) there was no difference. The system was ECU controlled and had been retuned to make it more active.



Still, better to have it and not need it than to need it and not have it.

[MrOizo]

The finer the water droplet size, the better - evaporating quicker means dropping more heat from the intercooler.

"The effectiveness of an intercooler spray is largely determined by the water droplet size – a very fine water mist will evaporate much more quickly, absorbing much more heat than a system generating large droplets. Note that this is a key point when it comes to selecting an intercooler spray pump – water spray atomisation is best with a very high pressure pump."

I could definitely benefit from this, a short blat in the twisties sees my intake temp skyrocket to 52c, cruising temp around 31, ambient about 20.

Trust side mount. Never again.

Can't be all bad if some manufacturer's fitted them. I have my doubts at effectiveness of a washer nozzle as they don't mist the water as mentioned above. Later model car washers (specifically VE holdens) I've noticed have a much finer spray. Or use garden type dealio's

[RomanV]

You can get misting nozzles on trademe or whatever.

Super fine nozzle, spraying out a super fine mist...

Only problem is that a tiny spec of whatever, and it's blocked.

[Mr Ree]

Bunnings sell the fine misting nozzles for plant irrigation systems, I just bought a selection of them and used the finest one.

Not perfect, but cost $3.20 compared to buying a HP pump and proper nozzles.

[strx7]

adding some form or alcohol/solvent to the liquid will; make it absorb heat from the intercooler faster.

TBH you would all probably benefit more from a digital inlet air temp guage which will give you a better understanding of how an intercooler works.


inlet temp of 51 degrees is path of the course for a turbo'd car, that isn't that bad. i have seen an inlet temp of over 130 celcius on a datalog of mine.

[Stott69]

Well after a read through some of this I might look into better nozzles. Get it running first and than evolve it from there

Change to an ATS top mount.

Just sent this setup (minus core and joiners) to the scrapyard with the shell. Assumed no one would want shit like this nowadays

Have only data logged IAT from a few cars,

My race car usually see's 25 - 35 deg IAT under full load race conditions,
but the hayabusa turbo MRS with the water cooled Intercooler see in the 40's for IAT.

I would have thought much higher than 50 and you would start running into problems.??

Where did the MRS's build thread go? Havn't seen an update for a while

still there somewhere, hasn't been many updates, just been using it.

Will look and see.
