Default Cooler Throttle body

I have been told disconnecting the water connections to the Throttle body is good senses if not in a cold climate?

Just how much impact is there?

Not much. But I guess all the little things add up. I did it.

Does make a difference on keeping the incoming air cooler, the more cool the more dense better performance! Unless you might be drinving it this winter in Alaska you can go ahead and re-route it.
Good Luck wro87

I found that after by-passing the coolant hose running into the throttle body my plenum is much cooler. It also makes it easier to remove as you are not dealing with the hose & coolant. From what I understand it was only added to prevent freeze up for areas where the weather is sub freezing for extended periods of time.

Ok, I'm inclined to believe that, so I ask this? All hypothetical of course.


If you plumbed up a small heater core [filled with a glycol], and stuck it in the air stream [or better with the Aux fan blowing on it] and added a little circulation pump would the the weight be worth the "COOLED" throttle body??

With that setup you would only cool down to ambient temp. The incoming air is already at ambient temp.

You only get something like 1 hp for every 10 degrees cooler. Most likely the cooler would block more air and you would loose more hp than you get from the cooling.

Don't some drag racers use dry ice for their runs, going so far as to make little ice chests for the blocks of dry ice on the intake?
