hey guys...

I know alot of us prelude owners suffer from extreme under the hood temps especially those of us who live in the south. I wanted to ask everyone to post up there idea's, thoughts, theorys, and accomplishments on the matter of reducing the temperature.

One idear I been thinking about. My header is exposed because who wants to look at that nasty heat shield when you've paid all that money for your "bling" haha...

I want to wrap the header as well as my intake tubing with header wrap in theory keeping the intake air cooler. anyone tried or done this ?? if so, results ?? and pictures ?? Ive got some nifty looking black wrap but need some hooks or some type of fastener i guess. Lets hear some other ideas too... Hope I get some good responses outta this one.........

 

in my turboed 92 i took off the weatherstrip by the fire wall that seals the hood. this allows heat to exit the engine bay easier. also exhaust wrap is ur friend.

 

doesnt this allow water to "flow in" the same way the air "flows out" ???

i dont want my "bling" getting dirty heeh

Anyone know where to get that heat wrap tape?

A guy from another forum wrapped his exhaust and intake with heat wrap and said it did wonders, said it dropped the temp of his intake charge big time. Downside- you are covering up your shinny headers and intake.
http://www.marcuccimotorsports.com/billy this is a link to a picture of his wrapped p intake.

Even though the wrap sucks for you aftermarket lovers, the wrap will do well for us stockers. Of course other than my Ebay intake There is a writeup on Superhonda and it shows how to make your intake piping heat coated sort of like the AEM intakes -

This would make a cheap intake look nicer and you wouldn't have to heat wrap it at least It's a good read.

Thats a pretty good write up. Somehow i think the heatwrap would work better though... I dont think it looks bad at all...

anyone else have opinion....
anyone else have more idea's ???

 

replace coolent with redline water wetter mixture. it will make it run at a lower temp. it lowered my overall coolent temp an 1/8th or so on the gage.

 

i know royal purple also makes a additive that goes into your radiator called purple ice and its suppose to lower your temp up to 10 degrees. they sell it at the place i get my oil change. i dont remeber how much it cost but i do remeber it wasnt that much.

 

i already run the royal purple additive... but this is good thinking, keep they idea's coming....

by the way the additive did work... i also have been using royal purple oil for along time now... i remember that it made alot of difference when i first switched to it... smoother, cooler, last longer, and yes, the butt dyno gave it a thumbs up too...
I talked my pops into switching to royal purple in his 2002 tundra and it made a bigger difference in his practically brand new car than mine... i am a happy and loyal royal purple customer

 

While looking for header wrap I came accross this site, http://www.centuryperformance.com/heatwraps.asp

Makes me second guess the whole header wrap thing, what do you guys think? Will we kill our headers by wrapping them?

hey... thats pretty interesting, but i dunno... in any case anyone know exactly what it takes to get your header coated with this jet hot stuff price/where to do it etc. .....

 

Here's a link:

I'm going to have to call bullshit, at least on a street motor.

Aside from the fact that he lists out all of these "facts and stats" and never once lists a single source, I don't see how he can say that "wrapping is bad but coatings are good" and then go on to show how they work the exact same way.

I've ran a wrapped mild steel header for a few years now and have had no problems. It is still structurally strong, but as any mild steel exhaust component will do, it has some decent surface rust. I plan on using a ceramic-based paint on my next header before wrapping it, if I run a mild-steel header again.

 

Also, forgot to mention in the last post: a vented hood will do wonders for your temps. It can be startling how much cooler it is.

 

^^Agreed. I had header wrap on my 3g for 4 years with no problems.

That link is interesting, but he's talking about NASCAR engines. Racing engines run extremely lean, which makes the exhaust gases much hotter (right?). No daily driver engine is run that close to blowing up.

I've seen the Stock Hood Lifts......Where the hood mounts can adjust up to create a cowl effect with your stock hood. I have only seen pics....Do they really exsist?

 

Those of you that have wrapped your header, does anyone have before/after intake temps? I'm always interested in dropping intake temps since mine are inherently high with the JRSC. I think I may buy a roll of wrap and do my header, and if I have enough left I'll wrap my intake too. I have plenty of datalogs the way it is right now, so we can compare temps before/after whenever I get it done.

That will be good info to know and share... when you do it, make sure to post it up on this thread !!

I use Hondata Datalogging. Before and after results show that the Royal Purple works.

On a cold day on the freeway, I'm usually around 190 degrees. On a cold day on the freeway after Royal Purple, I'm usually around 182 - 185 degrees.

On a hot day on the freeway, I'm usually around 195 - 197 degrees. On a hot day on the freeway, I'm usually around 190 - 193 degrees with Royal Purple.

On the streets, there wasn't any difference in temperature. However, with Royal Purple, my engine temperature rises slower, so it takes awhile before it gets hot, and my fan turns on.

 

Does CF do anything heat transfer wise? Or is it just lightweight and bling blingy

 

Why not take off the intake manifold and heat treat that, as well as the intake pipe. Maybe someone with an extra can give it a try. Im done taking my car apart, but i got an extra stock manifold. Use a hondata intake mani gasket, jethot coat the intake manifold, headers, and intake pipe. Then see if you can make some sort of duct from the foglight/headlight area to direct cold air into the engine bay.

 

From my understanding, most of the heat going into the intake manifold is from heat transfer from the head. Hence the phenolic gasket.

Carbon fiber, a carbon fiber hood in particular, acts as an insulator. When you run a carbon hood, you're essentially preventing the heat from escaping through the metal hood, which would normally accept the heat transfer from the engine bay.

This is why carbon fiber mufflers on motorcycles are great. If you have a passenger who inadvertently touches the muffler, they won't burn themselves like they would with a normal, metal muffler. Unfortunately, c/f is perfect for taking weight off the car, so it's a give-take.
