Intake Manifold Water Cooling?

[raddavey]

Should I disconnect the water lines that run to the intake manifold? Wont he 80+ water just be heating the manifold increasing my intake temperature? My temp sensor is on the plenum and rarely gets over 40 degrees on hot days and generally around ambient but I'm curious if the actual air temp is much higher going into the engine.

Its an E15ET btw.

yep just leave it all off, piss the "log" off as well.

you'll loose some of your cold start but wont be too bad.

it's there to prevent icing of the manifold, which in turn can cause the fuel droplets to solidify or moisture from the atmosphere freezing the throttle butterfly. This happens from cold dense air being "stretched" as it passes through the butterfly(s) creating a rapid cooling effect. This is never going to be an issue somewhere where it's always hot and dry (such as WA) but for those of us on the lower eastern states or higher altitude areas then it's a good idea to leave it connected.

OK cool yeh Log is already gone. Will it be ok on the cool 6degree nights?

The cool 6 degree nights if it is a bit moist may give you some trouble, particularly if your engnie is also cold. You can get around it by warming the car up properly before going anywhere.

cheers

I have found that the biggest problem is long drives at constant speeds such as on the freeway. driving around town I have never had it happen.
