Gotta be careful not to hydrolock the motor though. Was running meth through the CP too.

Lost all the pics and logs as my laptop is was stolen.

Genius JB

I, like coupes got obsessed with IAT reduction. My spare parts box was pull of at least 30-40 various meth nozzles, over 100 different types of line fittings, 4 meth pumps and at least 20 metres of meth tubing.

I also tested with two nozzles on each side spraying the IC too. It worked really well. Logs all showed good IAT reduction on long pulls with no heat soak.

Obsession at its best lol

What worked and what ended up being a dead end?

i too struggle with high AT. pods soak up the heat too. im trying to route them behind the bumper somehow or even spray water on the ic by diverting the headlight washers.

Great idea with routing the headlight washer to the fmic. Keep us posted on how you go with the DIY!

Coming from an Evo 6.5 TME which came with a factory fitted intercooler water spray this was something I hooked up to the 335 awhile back

Just bought a cheap washer kit off eBay had it hooked up with a switch in the glove box and the washer nozzles pointed at the IC

Works really well on hot dry days once the IC has become heatsoaked

I remember the drag guys saying they can’t use this setup though because any fluid leak on the track is a big issue but great cheap option for street and mild track guys I reckon

What if you used a misting jet for the IC spray instead? Most of it would vapourise rapidly if you don't spray it too much so you might get away with it?
