Aqua mist S4 IC Vs RS4 IC

[Philws4]

Has anyone done any dyno plots or VAG COM logs with the standard S4 IC's with a water spray like aquamist and compared the results against the RS4 IC's(without the waterspray)
As the RS4 IC's are quite pricey (and used ones rare) and involved to fit i was just wondering wheather this would be a viable alternative.
I know the S4 IC's are not as strong as the RS4 IC's but if you have no leaks and can keep an eye on their condition visually and with a regular VAG COM checks then this may well be a worthwhile mod!!

Phil - I reckon the aquamist on S4 coolers would probably be negligible relative to RS4 coolers w/o aquamist ... reason being: RS4 coolers are ~40% bigger than standard S4's - so less pressure drop across them and their cooling capability is more efficient (because of bigger surface area) ..

I think it's a false economy to go for the water-spray on stock coolers as opposed to no water-spray on RS4 coolers ...

Go for the RS4 coolers.
