Substantially lower intake temps. cheaply
Thermo coat your lower and upper intake manifold for a colder intake charge equaling greater horspower.
Step 1 get your lower and upper intake manifold sand blasted. Step2 scrub them with bake parts cleaner not carb cleaner. Step3 spray them with thermo coat and then bake the for 300 degrees for one hour. Step4 assemble. This coat will susbtantially lower heat transfer from the turbo into the lower and upper intake manifold. Sand blasted manifolds 40$ Thermo coat 15$ Piece of crap spray gun 15$ |

Agreed heat soak will set in regardless, best way to lower intake temps is evaporative cooling through something like methanol.

so ceramic coating will not help, or heat shielding?

We aren't looking for an intake temperature drop. We are looking for a lack of heat increase namely from ambient engine bay heat. You can't stop the inevitable but you can slow it down. Thermal coating is one way to do it whether it be on the manifolds or heat shielding around a turbo. It does work. Don't expect to be faster though due to lower intake temps. That's not what it does.
This isn't a worthless mod. It's a good one and cheap makes it better. It isn't a miracle power adder though. In fact it doesn't "add" anything. It's only slowing down the onset of power loss through heatsoak although it will eventually happen anyways. |

Um, yeah.... Refer to post #1 for topic information. "We" is a generic term meant to imply those who are doing something rather than a specific person.

As per your post: "We aren't looking for an intake temperature drop." Therefore, when you use "we", you are either not including the original poster, or you do not understand the post. Additionally, I would certainly like to have an intake temperature drop with my car, so I am getting a feeling that "we" really just means you, unless anybody else would like to add to this thread and state otherwise.

Addition to mod
I like Rotary God's mato
"One test result is worth more than a thousand expert opinions." "If you aren't testing, you are guessing." "Cheap usually costs more and rushing things usually takes more time." I have actually tested this out and it does work I have also kept something to myself and it is a mod that goes with this as well. This is a mod in wich you bore out the bolt holes in your manifold and use fenalic tubing to surround the studs, use the buy the same material in washer form and cut out gaskets and sandwich them in between your LIM and block and between your LIM and UIM and throttle body if you like. Although, I regret not shooting the manifolds with a temp gun but it was a mod that allowed you to beat your car up on the street with and go out to Auto Cross and consistently run it and handle the manifold with your bare hands and without a problem. The coating actually doesn't go on manifolds. This is what the label says coating is Powerkote High temperature thermal barrier coating CBC1 For: Pistons, combustion chambers, and valves. Tech Line coatings, inc. 26844 Admas Ave. Murrieta, CA 92562 # 972-775-6130 Part number 2213 Batch-0512-8 This mods slows down heat transfer from the turbo and the block itself. The intake temp have been lowered substantially seeing how there is no metal to metal contact between the block and the manifolds however this was on a stock turbo pushing 10psi. And the water going through the manifolds was blocked because I was running FD rotor housings. If you really don't believe in this mod then check out the heat tranfer numbers on fenalic and the Powerkote. Oh, the fenalic is material all together is 60$ and takes about a couple of hours to put together. |

do you not care if engine management sensors are reading correctly? do you not care about the temperature of the ambient air flowing through your air filter? do you not care about all those wires and vacuum lines that become brittle from the typical high temps of an rx7 engine bay? at what temperature do engine bay components start to become damaged? do you know the temperature of your engine bay during normal and spirited operations? an additional note: i talked to turblown about their thermal coatings a while back and they told me about a couple of the benefits they have seen from coating rotor faces. first they saw a drop in oil operating temperatures, they also claim to see quicker turbo spool times. i dont have experience with either so this is really just hearsay but i can reason that both are possible. |
It's Phenolic, not fenalic. I've done a very simular mod, as I have tons of the stuff laying around in sheet form here at work. I've done essentually the same thing except I've made phenolic spacer between the block and lower intake manifold using 1/4" phenolic sheet too, then as you bored the manifold holes out and placed phenolic stand-offs/barrels to isolate the studs and used phenolic washers.
