I rememeber a thread a while back about someone saying that they put reflective tape onto the underside of the airbox to reflect the engine heat away somewhat. And that it reduced the incoming air temp. which as a result make the air more dense, denser air will ulitmately give more hp, etc ,etc.
well i tried this experiment and it cost me $10. I made a video charting my impromptu experiment. i know it very unscientific but it looks promising and you have nothing to lose.
both ways show 9 degree increase, yet with the tape, the air was always about 20 degrees colder.
ps. yes i know it wasnt moving so incoming air would be cooler, but it goes to show the heat soak versus reflectability aspect nonetheless. either way i had fun doing it :-)

BTW: is that the palm OS program that reads the ECU?

 

I am sorry I could not read the air temps from your Video, could you post the numbers?

Also if you make some Phenolic insulation spacers to be placed between the intake manifold and the cylinder head you will see some very large drops in air temps.

My C280 went from having the manifold too hot to touch after a hard drive to being able to hold your hand down on the warm manifold after the phenolic spacers. My infared temp gun showed temps drops of from 30-40 degrees F.

I guess I need to do both methods on my C43.

thats a good idea im gona try it

 

Yes what software is that ???

 

How thick are these spacers? And where can you find them at?

 

I really hate to be a pest but I can't view video's because I use a linux machine. Any chance you could grab some of the key stills and do a small write up?

What kind of tape? Thermal or reflective?

 

It plays just fine over here (Slackware 9), using mplayer ( http://www.mplayerhq.hu/homepage/design6/dload.html ). hth

 

itll read any ecu on any car imported into us since 96.
i got it mostly to read what the check engine light meant, and reset it. i'll take more pics tom and post info

thanks... I need a small footprint (166mhz 48m ram) Redhat 4.2 (upgraded almost completely through redhat 7 rpms + src. Still using Kern 2.2.x though. All other video players have brought this little laptop to it's knees.

It's like a marriage though, I have had this machine since 97' and I just can't dump it.

Edit-- needs gcc3

 

i got a lot of interest in the OBII reader so I put up some pics at
http://161.58.248.45/cgi-local/ultim...c;f=3;t=000061

And its from Auterra, only about $200

More importantly, no one has addressed the pith of this thread. Does it look like it makes sense and helps out with hp improvement?

 

My thermo shiled came yesterday ...

I will install that and my k&n filters ....

Stopping heat is almost always a good thing .....

Shane

 

I installed my k&n s and the heat shield on the botton of the air box.

The air box no longer gets hot, seems to work ....

We will find out when I go back to the track ....

Shane

 

Completed today on my E500. Easy to do. Pics at the below thread.

You have a PM.
