I'll chime in. I had a full Cry02 system in the C32 and it was very benifitual.

Paint ball stores will not fill a 20# bottle btw. They are limited to 10# by insurance. Any fire extinguisher place will do it tho for about $10.

I was able to get about a half day of track runs. You don't have to worry about the gas choking the engine if you are moving.

They sell intercooler sprayers which were nothing but a oval with holes poked in to "mist" whatever its attached to.

Better solution is rear mount split system / bigger intercooler.

Best solution is rear mount split system / bigger intercooler and cry02! But not cost effective. I was hot lapping numerous times without effect on IAT.

And yes, we would spray down the engine compartment with no2 all the time, just at a distance. Hot equipment and immediate cold temps dont play well.
