Ok, so I've been going through my R33 gtst these last few days and I've fixed up all the washer motors.
One of which was for an intercooler spray kit that was already installed on the car.

would water on the intercooler really do much?
I'm skeptical myself, currently in 2 minds whether to rip it all off or not...

Cheers

Had a ghetto IC spray setup on my old zed. I had an LED that flashed when coolant temp went over 95. If nothing else, when boosting hard up mountains and the LED came on, I would hit the spray and almost instantly the light would go off.

Haha, I've always wanted to have forward facing sprayers that spray brake fluid all over the picks that cut me off when driving through the cbd...

Well I'll leave my kit on there for now, I've got it disconnected as it runs through the water pretty quickly and there's no on/off switch yet besides the boost switch.

Might be useful over at Calder Park for the Friday night street drags Haha

AFAIK, the main idea for water intercooler sprays is to prevent or prolong the time it takes for your intercooler to reach heat saturation, in turn making your car run at or close to peak power for longer.

Here is an article explaining it in depth (it's even tested on a R32 GT-R) http://www.autospeed.com/cms/article.html?&A=0527

On the other hand, if one wanted to drop their intake temps below what your intercooler could do by itself, I'd be looking at something like this... http://www.designengineering.com/category/catalog/cryo2-system-components/cryo2-intercooler-sprayer-kit

I put the Autospeed spray controller and a home built spray setup onto the SMIC on my R32....um.....many many years ago. It did good things for that little intercooler. When I upgraded to a much bigger FMIC, I couldn't ever really tell the difference between having the sprayer functional and not having it. So I stripped it out of teh car.

Whether they are useful enough depends on the ratio of hot air being made to cooler size and your vehicle usage model.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
