Water Cooled Inlet
Turbo Mini Forums

I know I am in real risk of opening a can of worms but I really want to know the truth as some people say it should be used as designed and some that don't use it. I personally have never used it but I have allways wanted to use it with a charge cooler. But I don't think I will ever be using a charge cooler.
Anyway has anyone tested inlet temps with it connected/disconected?

If you are talking about inlet manifolds with water piped through them it's not to cool it. It's to warm it up faster from start up allowing warm up enrichment to end earlier. It's an emissions thing.

p.s.

on the charge cooler front it doesn't have enough surface area to be effective.

it does help part throttle driveability in the winter, on my 998 it cured its carb icing aswell however it didnt on my 1275
i think can of worms is the best way to describe it, try fit it if there is no gain there is no harm n taking it off

Hot coolant at 90+ deg C is never going to help power. I'd be disconnecting it if I had one. I don't think it makes much difference though for the same reasons it won't work as a charge cooler. Not much surface area..

Mixture isn't really positive/negative. It's right or wrong. If you alter anything from when it was last tuned then it needs checking and adjusting. This is why programmable fueling as well as ignition is the easy option.

Water heating of the inlet manifold is not so much an emissions thing as making the car more driveable, especially when either the weather or the engine is cold.It makes a rwal difference in that way.

If you are prepared to sacrifice that aspect, then a cooler charge is obviously better for power.

it makes a massive difference if its real cold

They work by heating the manifold so that if cold fuel drops out of the air and onto the manifold it will evaporate and go back into suspension. This is how it helps cold starts. The effect on the incoming air temp is negligible because as said the small surface area and time in contact mean there is little heat transfer.

hmm, so will this help a little on cooling our hot mini's? i was thinking, even if it has a small contact area, you would spread the water in a metal housing, wich will be cooled by an intercooler. what do you think?

you mean cool the water with the inlet air?
doubt you'd notice for the same reasons

Well that's cleared that up then! I must have made that argument up in my head.
I understand about little surface area and the charge cooler idea not working also so glad I asked.
And as I don't use my car in the winter i shall continue not using it.

Just take your intercooler off for the winter problem solved
and just to preempt to inevitable abuse ill get for that comment I was only joking
