ok, so i just got a set of Vortec heads for my 350, and i got a performer rpm to with them. the vortec heads don't have an exhaust crossover, so edelbrock put one on their manifold so you can plumb it with exhaust or coolant to heat up the intake manifold. its externally plumbed (two 1/2 inch plugs, one on each side of the manifold).
i got to thinking at work today. what if i put an extra reservoir under the hood of my car, filled it with ice and water, and ran the ice cold water through the crossover under the plenum with an electric pump?
it seems to me that it would have the same general effect as icing down the intake. i would think that 40 degree water would be better for the intake charge than hot exhaust or antifreeze.
possibly a second pump piggybacked on the return side with a pickup tube so i could get the water out when i didn't want it to be there. straight water boiling under the plenum sounds like a bad idea.
any thoughts or opinions why this would/wouldnt work are greatly appreciated, as are ideas on how to set this up. (my strong suit is "african engineering", i suck at fabricating)

 

why go through the trouble of plumbing a icing system for your manifold when you can just put ice packs or something on it. just seems like a lot of work. i am pretty sure those exhaust crossovers are there for a reason as well.

 

sure its a intresting idea, but do you have to post it twice?

 

wouldnt the difference in temperature pose a threat of cracking the manifold?
just like how people dont want to spray water on a hot engine because it could crack the block?

 

there is a difference in cold water being sprayed on the surface of a metal and the metal being submersed or cooled from within by cold water.
