intake manifold gasket
 

im not sure how mazda has it setup, but recently my brother installed hondatas plastic intake manifold gasket on his rsx-s. i was wondering if building something like this for the 8 would be plausable and even open up some horses. i searched the net to see if anyone has made one for the 8 yet and found nothing. maybe someone could explain mazdas setup and verify if this would work to improve power or not. thanks

not familiar with the product. how exactly would changing a gasket "open up some horses"?

Considering the intake is a composite (Plastic)....putting in a plastic spacer to keep heat transfer down....... to keep intake air cooler....it won't work !

^^^^^ Thats what I was thinking

Ok... so I'm not the only ignorant one here. I echo Zoom44... what is this product you're talking about? Got some links or something?

its a Hondata intake gasket. Keeps heat from transfering to the intake manifold from the block. Cooler air = more HP.
I looked at this on my old 2002 Si

has this been measured by anyone but the company that produces it? the air doesn't stay very long in the intake manifold to soak up much heat.

it's just ricer bullshit, don't sweat it. it's for a honda for crying out loud.

That was my thought when I first heard of it

I have some South Pacific beachfront property for sale in North Dakota if anyone is interested!

Go drive your car around and then feel the intake manifold. It isn't hot since a good amount of air is flowing through it. Let it sit and idle for a while with little airflow through it and engine bay heat not escaping. It is extremely hot. Why do I want to have a cooler intake charge at idle?

This isn't about reducing idle intake temperatures. While running the engine, it combusts gasoline and one of the energies that is created from this reaction is heat, along with the momentum that pushes the rotor. Now since the intake manifold is bolted onto the engine and the engine is heating up due to the burning gasoline inside the engine there is a potential for heat transfer. Now on my brother's RSX type S there is a product to replace his stock metal intake manifold gasket for a thicker plastic one that transfers heat much less. The results are dyno proven. Here is the website : www.hondata.com . They make these gaskets for more than just honda's and again the results are dyno proven. The gain may only be a few ponies, but hey, every little bit counts. these theories are mostly my knowledge of piston engines, but the principles should be the same. even if i am wrong which i am more than willing to accept, where is your reason to mock me. rotarygod i followed your posts for a while as they were very informative and im a little confused as to why you mocked me. anyway with your response about idle temps take this into consideration. youre at the track and your waiting at the starting line at IDLE. the intake temps are hot. so explain to me why you would want to wait until the race started or even a good deal through it to begin to get cooler charges, because id be very interested.

I wasn't mocking you. I was mocking the people who were mocking you!

Just something to think about when it comes to dyno results. The only reason I bring this up is because it happened with a sceptic on the forum here last year. If someone posts a dyno result and makes a claim, who's to say they aren't lying? Maybe it is true. Maybe it isn't. What were the conditions of the before and after tests? I don't believe any one single dyno chart vs any other single dyno chart. Also realize that the Honda crowd is some of the most easily influenced group of brainless people out there. This isn't an insult to you or your brother but it is aimed as a general criticism of many of the rookie Honda kids out there. If I make a claim and put a picture of a before and after dyno chart on a box, does that make it true? What if I didn't actually test the product, didn't tell anyone I was lying, and still posted the chart and made the claims? Is it still true? How would anyone know? I see alot of Honda guys running those horid Venom intake manifolds and those waste of money aftermarket headers. They get a few more ponies on the extreme top end at the sacrifice of power through 99% of their powerband. But they ultimately have more power! On paper it looks good even though you are slower. My whole point is that you shouldn't believe everything you read. Maybe it does gain a little power. Maybe it doesn't. I guarantee that even if it does gain power, you can't feel it though. If every little bit isn't noticable, it didn't really count for much did it? One last thought on this. If this manifold spacer, which is extremely cheap to manufacture, works so well, why aren't auto manufacturers doing it? The manifold bolts that hold the manifold to the engine are still metal and still transfer alot of heat. They'd have to be plastic too. I classify this product with the tornado. You know, they make dyno claims too!

Once again, I'm not mocking you. I'm just making a point. Please don't take offense or anything personal. It isn't meant that way.

i sort of understand now and agree honda has a pretty brailess crowd, but some of the companies make good products and hondata happens to be one of the. the kpro programmable ecu is great. but i was just uninformed about this whole concept, thanks for clearing it up. i dont want to make enemies here but i felt like i was being attacked, sorry dude.
