Bypassing Coolant Passages to T-B!!

Bypassing Coolant Passages to T-B!!
Anybody here allready tried to bypass the coolant lines that are plugged to the Throttle Body?? In my pal's Tiburon it really improved power delivery when the motor was hot... ...but on my 626 V6 it screwed the IAC motor really bad!!
So, are those lines there only to prevent throttle plate icing at cold weather or they has another purposes... Like on my Mazda's IAC!
Makes me wonder the purposes of CAI if it's to heat up the throttle body to 185°...

I did this on my old S2K. It does have an IAT sensor. It ran perfectly fine after that. It didnt make the car any faster, but it definately helped with the heat bog issue down here in florida. All I did was put a ball bearing in the coolant line to block it off. Very common mod in the s2k community. But if you live in a place that sees very cold winters then you should not do this mod as the TB may freeze.
IMO its not worth the trouble.

i did this on the fit. i need to take pictures of it so you guys understand. it definately makes the tb run cooler. before after 30mins of driving i would put my finger on the tb and it will burn me. now it just feels sightly warm.
as far as performance nothing really felt on my butt dyno.

I did the bypass on my '07 Sport and could't feel any difference, either positive or negative. But I will repeat the other reply warning "don't do it in the colder areas of the country" because you do not want icing problems.

as i said, i remember on a Hyundaï 2.0 Beta engines it did wonder!! But unlike the Fit upper plenum, the Hyundaï intake manifold is all aluminium so the throttle body was heating the entire intake like crazy!! On a KLDE Mazda engine, it did well for power for the same reason but caused the IAC to malfunction thus causing Idle surge!!
