any serious benefit Heat Tapes?
 

will help minimize heat soking. whatever heat generate from engine bay?:iono: im willing to heat tape warping the whole IC pipes intake pipes with DEI heat tapes dose those work well keeping the pipes cooler??

anyhelp ill me much appricaite it thanks..

Throttle body has coolant running through it so unless you're talking about a section close to the exhaust or the turbo I dont think there is a benefit.

Here's some reading for you

I know there's more out there, but that's all I found in the first 2 mins of searching.

Honestly don't know how much it would help, but surely it would if you were sitting in heavy traffic. Black absorbs and radiates heat as well, so its going to take the heat from being behind the radiator and on top of the header and radiate it into your intake path... right? Questions like this make me wish I was an engineer or something.

I would put gold reflect tape all over the I/C piping.. heat wrap the headers, turbo blanket and i would vent the hood.

I 2nd the vented hood idea as well. Especially because some are experiencing hood lift at higher speeds.

Yes, it helps. Any older forum will have at least one thread where someone throws up some FLIR-type pictures of various tape arrangements in the engine bay, along with a k-type thermocouple in the engine bay to show differences in ambient bay temps.

Well here's a question.

We know the heat tape can overall engine bay temperatures down. Now, the heat has to go somewhere right? Does the heat tape end up trapping heat inside the pipes, making the charge air hotter?

It doesn't keep engine bay temps down, it reflects heat away from things you don't want hot, like the intake.

Edit: what you're talking about is why someone else mentioned a vented hood

edit 2: not to be confused with heat wrap/exhaust wrap which keeps heat inside of your exhaust and out of the engine bay.

Checked your coolant temps lately? (They're not cool) Coolant through the throttle body HEATS the air. The coolant will almost always be warmer than air entering the throttle body.

The coolant flows into the throttle body to act as a heater for the throttle body mechanism, in especially cold climates.

If you don't experience these cold climates, removing the coolant flow from your throttle bodys is one of the first mods you should be doing.

Are you quoting me to tell me coolant is hot? That was the point of my post. Wrapping your ic piping is futile unless its exxceding throttle body temp.

I disagree.

even if the coolant heats up the intake air, lower input temperatures will ultimately lower temperatures past the TB right?

The coolant hoses to the TB are to keep the TB from icing over (like previously stated). It has almost no effect on the temperature of the air moving through the TB compared to the amount of heat the black plastic of the intake path/manifold absorbs from the engine/bay.

Heat reflective taping the intake path might help keep the air temp from rising even more, but in reality, you have to look at how long the air spends in the intake path (less than a second, maybe a full second at idle). Reflective taping has a greater effect on keeping heat out of closed systems, like brake lines and coolant lines, because they can absorb heat from their surroundings and trap it in the system. Sure, the coolant system has a way to manage it's own heat, but the more you keep out of the fluid, the less work your radiator/thermostat have to do. The brake system, on the other hand, has almost no method to reduce fluid temps, and is very susceptible to heat transfer from the rotors through the calipers.

This is getting out of hand. Let me start over.
What im saying is on front mount turbos where the maf pipe crosses over the hotside of the turbo there is a benefit. BUT just wrapping ic piping to shield it from abient engine bay temps when you have coolant running through your TB isnt going to make a big enough differance imo.

Im going to do the back of my fan motor on my fbm kit where its near the downpipe and my intake pipe where it crosses over the radiator hose and near the hotside to prevent heatsoak. BTW dei silver seems to handle more heat than the gold.

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.
