any serious benefit Heat Tapes?

[diss7]

The point I was making, was that the coolant into the tb is not there to cool it. It is there to heat it and prevent it icing up. However, its always there, always heating. Now whether it has a small or large difference to air temps, I don't know. I'd say small.

But its there. And if you dont have to live in fear of your tb icing up, you are best not having the coolant flow through your tb.

Wrapping your IC pipe from engine bay temps will have an effect. How much is again, hard to quantify, but it will make a positive difference.

Do both (wrap the IC pipe, and remove the coolant from your TB) and you have removed two sources of heat that lead to increased IAT.

You are right!

But at the cfm air goes in a turbo car, TB won't make a difference, if ir does it will be a couple of degree. Air doesnt change temperature as easy as water does.. So by the time air goes troughthe TB it wont affect the IAT. Irs not like air was sitting for a second at the TB.

But the intercooler piping should be tapes, reason behind this: the air stays longer in the piping, wich will occur in a hotter temp if the car runs hot. So you want to reflect this heat off more then at the TB..i would tape the cold side at least, since hot side already have higher air temp from beeing compressed. Sti can help doing so but very little

And not living in canada, i would take the coolant off from my TB also.

Keep in mind the throttlebody can freeze in much warmer temperatures than one would think thanks to the venturi effect. Cool, humid air is required for it, but freezing air is NOT required. It can happen well above freezing as it depends more on the dew point.

The small amount of time the air is rushing past this area isn't going to impact the temp of the intake charge (plus the venturi effect is causing cooling anyway).

This.

the AVO kit, (I believe FBM kit as well) and I bet several other turbo kits get the water supply for turbo cooling water from the throttle body line (essentially blocking the water out of the TB).

These turbo kits are sold in Canada too and there is no warning about any detrimental effects of removing this water supply from the TB. I'd say it is very much unnecessary to keep this hot water flowing through the throttle body.

That's all well and good, except the temperature needed to reach the dew point goes up under pressure, meaning it's MORE likely under boost.


There's a reason all the OEMs warm the throttlebody and go out of their way to do it on factory boosted cars. You also can't counter any sticking on a DBW throttlebody by using a bigger return spring...

The water line to the turbo comes from the TB, not to, and then is routed back to the return at the back of the engine. This keeps the water that is going into the TB from getting too hot, and keeps the flow through it as it was stock.

I stand corrected.
