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)

 

lol... intresting idea...


if you really want to get into it, whats to stop you from running a refrigent down there and REALLY cooling it off.. lol..

athough the diff in temp could cause warpage that would have to be taken care of....

neat idea anyway...

 

I believe you'll ice up the carb. that was the original intention of the exhuast crossover...to eliminate icing, IIRC.

 

A cold air/ram air system would be much more effective.

All that cool air comming from under the bumber or from a hood scoop, rushing into the manifold at full throttle will cool 'er off in a hurry.

 

only in the winter..........what about when you're at the track on a 98degree NIGHT?

 

i have never seen or felt a 98 degree night. i didnt know that was possible. anywho damn thats a hot night.

 

A few of the friday night drags back in july, a month of straight 100*+ days the air temp at the track at night was well over 100* mid afternoon/early evening was 120* the one day I went for elimionation TT.

 

i used to live in texas.

i was at ennis(1/4mile strip) one weekend, and it was triple digits all day and 100-98* at night depending on what thermometer you looked at.

 

dude come to arizona. mid summer it is like 112 in the day and still about 105-108 at night.

no ice on my carb

 

it wouldn't be a constant on thing, only when you're at the track or cruising around and decide to cool down your intake charge. wire it up to a toggle switch inside somewhere, and flip it on when you need to. it would probably be easier to ice down the intake, but i figured hey, i have this spare crossover under my carb, why not take advantage of it. i just wonder how effective it would be, and how long it would take to actually cool down the air.
