So I bought one, thinking I would use it when I get the cosworth plenum. Currently I am using MD iso thermal gaskets.

Anyone have any experience with the Hondata--it's made out of some sort of plastic. Will the hondata or the MD iso thermal gasket be better to use with the cosworth plenum, or better to use the stock ones that come with the cos?

"Hondata have developed a special high temperature insulating gasket which replaces the stock intake gasket. This and bypassing several heat sources significantly reduces the transfer of heat from the head to the intake and incoming air giving you up to 5% more power.

Turbocharged cars often use an aluminum intercooler to cool the air compressed by the turbo. The intake manifold is also made of aluminum but because it is heated by the head from combustion and coolant, works in reverse to an intercooler by heating the intake air by as much as 50° C.

Fact: For every 3.3 °C (5° F) rise in intake temperature, air density drops 1%. The hotter the air, the less fuel the computer injects to compensate for reduced oxygen. HondaLogger datalogging software has enabled us to measure intake air temperature under varied driving conditions.

Around town, testing has shown an average drop of around 10 degrees C which is good for around 3 percent power increase. Remember though that 3 percent power increase is difficult to feel. You'd feel a greater change in performance getting rid of that passenger. In certain conditions a 30° C drop has been measured.

The Honda manifold is heated in up to 5 places. From the head, the interior heating takeoff hose, the cold idle valve, the idle control valve and the throttle body heater. The Heatshield gasket kit contains an insulating gasket, and installation instructions. A race version only version with the thermostat bypass blocked is also available.



The graph above shows the results of installing the Heatshield gasket and bypassing the throttle body heating and idle control valve heating. If you examine a Type R intake manifold you will find that most sources of water heating are removed. Further temperature drops are possible when in addition the interior heating hose is blocked. What the graph shows, is that as you open the throttle, the intake temperature drops slowly as it cools the intake. When you descend a hill with the throttle closed or drive around town on a light throttle the temperature climbs quickly. It takes a good 15-20 seconds for the temperature to drop again when you open the throttle. So if you start your 1/4 mile drag with a hot intake manifold - you are only starting to develop maximum power near the end of the run when the intake has been cooled. The Heatshield gasket kit gives you 4-5% more power immediately by lowering the intake temperature. "

 

Anybody?

 

Hondata

Says it all.....

 

iam going to have to agree with that ^

 

So this product should be dismissed just because it is made by a reputable company that has primarily focused on Honda/Acura applications and not nissan applications?

If this was rebranded as "nismo" would you consider it?

The cosworth comes with a nissan oem gasket. I was just wondering if using this or the MD iso thermal manifold gasket would help keep down plenum temperatures compared to the oem basic gasket, as well if anyone had any experience with the hondata gasket.

 

Hondata makes some quality parts, and that gasket has been proven to work very well.

I am currently using 2 motordyne iso gaskets with my 5/16 spacer and still get some plenum heat transfer. But far better than OEM gaskets. I am also using the TB heater.

I think the Hondata will be the best bet.

 

Thx for the input. I'm gonna try it out when the cos arrives and keep the md one around handy just in case.

 

I know, I was just busting your chops about Hondata. They do make quality products. That should definitely help, I personally would probably go with MD Iso gasket.

 

All the info you posted about the Hondata gasket looks pretty good. Why don't you be the guinea pig and let us know if there are any true power gains?

 

will do

Going to get the car on the dynojet right now. Last time I dyno'd there was only with mrev2 and 5/16 spacer: gave me 251 whp and 233tq. After a bunch of mods's--I'm hoping to see some gains I will post when I get back.

 

that gasket looks deisel. MD version isn't nearly as thick, i wonder if it would be an improvement? Looks to be of a quality gasket regardless the name stamped on the front. Let us nkow how it turns out.

 

looks nice but I don't think you'll net any gains from it considering there is not much room for airflow in the engine bay, and everything is alumimum

what's the cost?

 

$45. Not expecting performance gains, just trying to lower air temps in the plenum.

 

$45? I'll take the stocker in that case

 

does it add vtec?

 

If you have the OEM gasket, already purchased the MD Isothermal, and now bought the Hondata, why are you asking for opinions? I guess I would have asked for input prior to buying a third gasket for the same application, none of which probably have any significant advantage over the other two.

 

Thanks for being a team player, good luck.

 

Its a good looking gasket, but when all is said and done its still just a gasket.

 

Got one for my 07 Si, Hondata is very reputable for their r&d in their products.

 

I think I'll just stick with MD's ISO thermal gasket.

vtec jus kic'd in yo
