before i get flamed, yes i already searched but can't find anything.

just like the title says.

not my cars but i'm using it as a example, hope the owners don't mind.



i heard that it made the car feel different. made same hp on less psi and response was different too. anybody has experience w/ wrapping the piping?

thanks.

I used to heatwrap the downpipe and noticed the engine bay was not as hot as normal. Performance-wise, there was nothing really noticable at all.

wrap all that you can

You don't wanna wrap the IC piping, that will keep the heat in and that is not what you want.

Not entirely true. Think of it this way, if your under hood temps are 150*F and your IATs are 120*, then the heat will not shed from the IC piping. Now if IATs are higher than under the hood temps, you will not want heat wrap.

I wouldn't i think you should let as much air try to cool the pipes as possible. good theory though.

i did find a thread actually but it was just people's theories on it. anymore personal experiences?

It's exactly what I said. You need to see which fits you.

very good point and very accurate

We noticed a slight increase in power.

i heat wrap my ic pipe thats near the downpipe, and i heat wrap the downpipe.

The downpipe and the charge pipe that is next to it are both wrapped.

im not sure if your asking me a question or just making a statement, but yes thats exactly how i have it

i would think it does more for keeping the engine bay cool, then adding hp.

it sounds like a good idea as the ic will cool the air down anyway.

but i would like to see some dyno test's for proof

i would heat wrap my whole engine bay if it wasnt so expensive

really though, a power gain or loss from wrapping charge pipes would be negligable, and i didnt notice a diff after i did mine.

i wrapped the chargepipe and downpipe and dump tube.

The first wrap kit I bought only covered about half of the downpipe length.

If you sit in stop and go traffic then I could see your temps being that high. However, at speed the temps should only be slightly higher than the outside air temperature. Think about how much air is moving around and through the bay.

It's called theory. The fact is Hondas typically have mediocre air flow to the engine bay. When you stick a huge FMIC, a big turbo, ramhorn/top mount manifold, and a 3" DP, radiant heat increases and air flow to the engine bay decreases. I don't know if the temps are 150*. If you figure during the summer its 100* outside, I don't see 150* being unreasonable. Again, they are just theoretical numbers to illustrate a point. Stick a thermometer in your engine bay. Compare IATs to under the hood temps. If the temps are similar, you want to use charge pipes with a moderate thermal conductivity. If the temps in the engine bay are hotter than in the intake, you want to use something with a low thermal conductivity. If you find IATs are higher than under the hood temps, use high thermal conductivity. It's not brain surgery. It's just about applying the best solution per case. There is no one size fits all answer in this case. If you find that all to be too much work, I'd just heat wrap all my exhaust components and run a material with a moderate thermal conductivity (mild steel would be a good choice).

PS: This is a tech forum boys and girls. Don't just do things for ***** and giggles. "Oh, I didn't feel a difference". "I just did it because it was cheap". "It seemed to make sense". Use some thought and theory, come up with a reasonable hypothesis and test it. Use that thing between your two ears.

my engine bay temps are alot higher than 150*F.
