Throttle Body Coolant Bypass (with pics), Want to bypass the coolant flow to your Throttle Body on you 5SFE? Options

[Spider77]

So, after quite a few PM's on how to do this I finally broke down and took some pics. You will notice however that I did not put everything back to "factory settings", ie, I just took a few pictures and hope that they'll help the ones who want to know how to do this.
First off though, a warning:
****THE COOLANT WILL BE HOT AFTER RUNNING THE ENGINE, THEREFORE TO AVOID BURNS I STRONGLY SUGGEST THAT YOU LET THE ENGINE/COOLANT SYSTEM COOL DOWN BEFORE ATTEMPTING TO DO THIS, I AM IN NO WAY RESPONSIBLE FOR PERSONAL HARM THAT MAY BE CAUSED WHILE ATTEMPTING THIS, YOU HAVE BEEN WARNED****

STEPS:
1:) You want to start by disconnecting your SRI/CAI/Stock Intake at the throttle body:

2:) Disconnect the 4 Vac lines (three on top, one that sits lower):

3:) Disconnect the Throttle Cables (one for Man, two for Auto):

4:) Remove TB by pulling the 4 12 mm bolts:

5:) Remove TB from Intake Plenum:

6:) You will notice three lines hooked into the TB, two outside line (coolant) and one middle line (vac). You want to "bypass" the TB by linking the two coolant lines together, using a 5/16th brass bard (male to male) fitting and screw clamps to tighten it down. Please do not use existing hardware as its probably been sitting there for a while and chances are it wont stand up. Please use new hardware (screw clamps).




7: After you insert brass barb (male to male fitting) and tighten down the screw clamps, you might want to install some vac caps on the coolant ports. Although I cant say if its required, for me its just piece of mind):

8: Reattach the Vac line (its the middle port)!

8.5: Totally optional, but at this time I did a minor cleaning of the TB, and the butterfly valve. Not required, but while its open, might as well, right?
9: Check your work. This is what you should have, two coolant lines "looped" together, two coolant ports capped (optional), and the Vac line (the middle port) reattached. Make sure that your screw clamps are tight (either use a socket or the right size four point to make sure its super tight...don't want leaks), and again, check another time. Once you are sure everything is done, place your throttle body back on the intake plenum, place the SRI/CAI/Stock Intake back on, and enjoy!

While I can not say this is how it is for different engines, the concept is the same. So, for all those people PM'ing me, this is how you do it (again ,mind you its not a pure step by step, but you'll get the idea), and for those who want to know how to TB Bypass on the 5SFE, here you go!
I hope this can help answer this question to some extent. If anyone sees anything wrong with this (ie mislabeling please let me know so I can correct).
Thanks and hope you enjoy!

sorry for the newb question, but what is this for in the first place? i dont get it!

coolant runs through your throttle body making it very warm.. the down side to any engine it taking in warm air, you car wants the air it takes in to be as cold as posible, so bypassing the throttle body helps with taking away that warm water going around it.

When air is 'colder' it is more dense, and thus contains more molecules of oxygen per unit of volume than warmer air, so more oxygen is available to the combustion process when intake air is colder. Also, the step-function reduction in air pressure as it moves through the throttle body into the 'vacuum' of the intake plenum is said to lower the air temp. This is in line with the statement by 4-eyed-freak. Can anyone point me to a good technical discussion of the dynamics of this process that explains it in more specific detail that spells out how much heat a warm throttle body adds to intake air temp, and how much cooling is provided by the pressure drop, along with other relevant info, like how fast is heat is being transferred from a warming block to the throttle body conducted through the intake 'pipes', and specifies what is the ideal air temp as it enters the cylinder?

How do these dynamics change as engine moves from cold to warm, and as throttle moves from idle to WOT?
