I was just rearranging stuff in my engine compartment and decided to take out the heat shield that separates the intakes from the rest. I drove it to school then drove back home. Then i put it back on and drove to a neighboring town. WOW! What a freakin difference. IDK what it was but the power wasn't there. It wasnt in my head either. Just letting people know that a heat shield would be a good investment.

 

Which heat shield?

When I made Damian's heat shield and "ram-air" duct, my intake temps dropped about 10 degrees.

 

The ones you can buy or make to separate the intakes from the rest of the rest.

 

Any heat shield that keeps engine heat away from the intake is of great benefit.

 

Which brand are you using ? ? ? ? Pettit, M2, ECT. /......

 

Pettit

 

I wonder if it's possible to use the Pettit "shield" with the Apexi Intake setup. I'm thinkin' if I use a separate mini filter for the airpump, I can probably get them to fit. Any thoughts?

 

Ya, with the Pettit setup i have it comes with a K&N filter to hook up to alot of that stuff. So it should be cool. The Pettit heat shield has a small hole that you can run a tube to there and put your filter on.

 

I need to make a new heat shield. I made one from an aluminum sheet before.

 

I'm getting my manifold and exhaust housing on my turbo ceramic coated before it all goes into the car. I don't know how much better that is then heat wrapping but it's going to cost around $200. I figured, spending $150 on a heat shield, then another $25-50 on heat wrap, it would add up about the same as getting it all coated. I've seen many rotary race cars before with ceramic coated manifolds and turbos, so I can't go wrong with that.

 

ha! I just noticed you were talking about a shield separating the heat from the intake, not heat shield on your turbo. lol

 

I need to shield my intake. I've got the RX-6 kit. It comes with the stupid *****-looking intake tube. I hate it. I think i'm gonna do a ram air to the bumper.

 

I have only seen one picture of a single turbo with any kind of heat shield.

 

pics mang!

 

pics of what?

 

I remember about two years ago stumbling on a site that tested cold air intake systems. Just about all of them ran hotter then stock. They had rigged multiple temp gauges throughout the entire system, post air filter, post intercooler and the stock location. I think the one from M2 was the only one that actually worked. They also tested the elbow and found the stock one was about 10C cooler then the Greddy, CF intake tubing also helped reduce temps. I wish I could find the site again. The test took into account just about everything.

The use of aluminium under a heat soaked hood is very bad, it has a high heat transfer rate and with under hood temps well over 300F the charged intake air which is cooler is were the heat goes. The composite plastic don't transfer heat very well making them a better choice for cooling. Venting the hot air from out of the hood would likely lower intake temp more then a heat shield.

Just try and touch your IC after a hard run, on my FMIC its as cool as a cucumber. The intake pipes just before the elbow will burn the hell out of you.

 

Exactly!

I wish I could weld.

 

How does that duct route from inside the engine compartment to the oil cooler duct opening?

Does that car have stock pop up headlights?

 

I don't know. You'll have to contact the original poster who did the fab work.

No, that car doesn't have pop-ups which is how they can route that tube.

 

i saw this picture before and figured it was inpossible to route that with pop ups, but I didnt know for sure. Now all my questions in life have been anwsered and my life is complete. hahaha

thanks,

Well, I'm not saying it can't be done. It's possible to fabricate something squeeze down there with pop-ups and provide decent air. Heck, most cars have defroster vent tubings which has restrictions in them before they open up about the size needed or smaller, yet they kick out some air..

I have thought about mocking something up with foam to do it and then having one made. I might see about it in the spring as the dryer duct kind of collapses on itself as you squeeze it down there.

 

I didnt know the great Majhik jacked threads. Well you guys when i meant heat shield i ment one fo rthe turbos like the Pettit one or ones that guys fabricate to separate open air filters from the rest of the engine compartment. But its whatever. Btw Majhik, im jk, no need to flame me about my comment.

 

I used 3" heater ducting($10 at Kragen) to route cold air up from the nose up throught the gap next to the radiator toward my K&N's. It hold it shape ok.

I recently received this 3" brake ducting from N-tech to go from the nose to my n-tech Brake rotor ducts. That stuff is heavy duty. ($60 for 10')
