but, i know it has to be better....I am a private pilot and knowing what i know about "icing" (which was just enough to pass the test :P ) i would not have done this if i lived up north ... and FWIW, my new LS2 throttlebody does not even have ports for coolant to circulate through it.

Has anyone thought of doing the reverse of what GM intended? Instead of putting a little heat there why not a little cold? I would think it would be easy to run a little cool air through that bypass hole, maybe something that could easily be shut off in the winter? A small line tapped into the air box with a shutoff valve comes to mind. You could hide it under the air feed going to the throttle body.

I like this idea. 

I think I will disconnect mine when I change out the thermostat.  But I think the cold air idea will need a better flow design (more volume).  Not sure by the way you worded this, are you talking of tapping into the A/C air box or the air cleaner air box?

I would think it would need plenty of airflow to have any of cooling effect.  If the air moved too slow it would have little effect.  I am thinking it would need some type of funnel design up by the grille and taper it down to add pressure and increase airspeed. 

Back in the day I had Holleys Projection on my 72 C-10.  It came designed to run engine coolant through it to keep it from freezing in the winter.  Since I didn't drive it in the winter, when I lived in Michigan, I had the thought of running ice water through it with ice and water in a cooler in the bed of the truck and a small pump to provide the flow.  I wasn't in to modding much back then so I never did it, but the thought was there if I ever planned on racing it.

IMO Carburetors take the venturi principle to an extreme and "icing" is very common, it can even happen in the summer months (well summer is not likely, but spring and fall, especially at high altitudes it is very common).  With our throttlebodys, it is not nearly as likely.

Especially not when you have a supercharger heating the air before it get to the TB.

I did this mod with a twist!!

I left it all connected BUT I added a T-valve to the line. In the summer I shut the valave which stops the collent from flwing through the TB. When weather turns cold I just reach in and open it.

Volia best of both worlds.
I like this!

No Intercooler after the SuperCharge?

If you drive your truck in the winter on a stock tb, don't do this! If you up grade your tb (might as well do the intake while your at it), i recommend nick williams, they are performance pieces that do not have coolant provisions.

A note on performance, I did this on my 98 Formula(not winter driven). I gained 3rwhp on a heat laden motor(made no difference on cold start), not too shabby.
