TB coolant bypass effects?

May I ask, has anyone ever measured the difference in air temperature before and after air travels past the throttle body? I understand that cool, dense air aids performance. So how many degrees warmer is the air after it rushes past the TB? I mean, it's not as if the air is sitting in a heated chamber. It's in motion - from the air cleaner, through the "plumbling," past the TB, and into the cumbustion chamber.
I'd sure like to know the answer to this question. After all, if there is enough of a temperature gradient to see a power difference, this is a mod that goes to the top of my list.

I was thinking about doing this mod because its inexpensive and some report a hp or two from it and every little bit helps.
I live in an area where its almost never below freezing, so I'm not too worried about it. but if I drove somewhere or moved somewhere that actually has a winter would this be a good mod to undo for the winter months? I know its designed to prevent the throttle plate from freezing, but how much of a risk is there of that happening really? I have a vararam, so maybe increased than stock in that case? just wondering if others that have done this that live in colder climates are concerned about it, or remove it for the cooler weather.

I have attended many Corvette gatherings & shows over the past 35+ years, some of which had Corvette development personal on site.
A few years ago I discussed this very topic.
First – the LS1 engine benefits greatly from the extensive use of plastics throughout its entire intake system. The heating affect of the air as it passes through that 3-inches of throttle body is negligible.
Second – In a street driven machine the benefits of the anti-icing affect of running coolant through the throttle body far out weigh the disadvantages. It doesn’t have to be subzero for icing to appear.
Third – Improving airflow in & out of the engine is the name of the game. (No secret here)

1) TB coolant bypass
2) De-screen MAF
3) Zip ties on air cleaner lid
4) Performance hood seal
5) DIY ported throttle body

Well I had REAL cold air induction the other day!! Blackwing filter and single digit air temp
!! Now there was a feel it in the seat of the pants difference!! Had been driving a while(Motor and fluids up to temp) got an open stretch and punched it in 2nd and Yippee!!! She definitely likes the cold air!!!

These motors love the cold. Unfortunately the tires don't.
