For track duty setup I was initially considering bypassing the coolant lines routed through the tb to help keep temps down during track conditions. Then I got to thinking of adding a small auxiliary cooler inline the system to cool down the water going into the tb a bit more in hopes that it will be cool enough to actually function at dispersing heat away from the tb to assist in cooling down temps. I found a cooler small enough to be easily mounted anywhere but still be functional.. http://www.partsgeek.com/catalog/200...il_cooler.html

the sandwich filter in that pic CAN be separated from the oil filter housing fyi, and that is the only part of that I would be using. basically it would go inline of the outlet line and cool down the water before it gets to the tb. Just a thought I had and want to get peoples opinion on here on what they think. basically those coolers are air to oil, but I would cap off the lines where the engine oil would normally flow through.

 

You're planning on cooling the coolant with....coolant? just trying to follow here since thats an oil to water cooler.

 

I'd ditch the lines unless you see a lot of snow driving plugging the EGR port in the head will reduce heat at the manifold as well.

 

Maybe something like this would work.

I would think that it would take something like c02 to make a big difference though from a cooling aspect, given the small area of the TB. Not really ideal for a road race car though.

 

lol dont plug ur EGR ha? EGR lowers combustion temps....which lowers the manifold temp!!!! EGR=good, for engine performance and mpg

 

are you using a snorkel? they have been shown to drop intake temps by something crazy like 10*

 

The EGR is not at all a good thing on a performance engine.
It is only to reduce COMBUSTION temperatures by displacing oxygen to reduce N0x emissions. It will increase the temperature in the manifold to some degree. Although, with it blocked off, there is no flow and air is actually a pretty decent insulator so with no flow going into the EGR passage, the heat transfer is low. Also, the EGR port in the head has coolant flowing directly over it so it reduces the EGR gas temperatures.

Block the EGR port in the head, use a phenolic spacer, and delete the coolant lines from the throttle body. KISS

 

No sir. The thought was to route a heat exchanger in between the bypass line and the tb coolant lines. The thought was that with the stock setup coolant going to the throttle body is x temperature. The idea with routing a heat exchanger would be that as the coolant flows out of the line into the tb the heat exchanger could in theory drop the temp of the coolant to x (what it originally would be) -(minus) x temp (after it has been through the small exhcanger). The question I am wondering is whether such a small exchanger will have any effect as to make it noticeable. I would not run coolant in the other circuit of that heat exchanger, that would just be silly of course.
Another thought is that air flow is pretty fast through there I wonder if it makes a difference either way??

 

That was another thing I'd thought about as well. Sounds like the best option would be just to eliminate the lines, plug the egr in the head and run a spacer like 03 pointed out.

 

Yep, basically the egr places an inert gas back into the combustion chamber where it keeps cylinder temps down due to the fact that the gas can not be burned again.

I have been thinking about just deleting the lines to the tb but Im always paranoid that one cold day will give me issues.
