Found the issue, why the engine on cold works better. I will try to explain what the problem is.\nIntake manifold gasket Hondata was created to isolate engine heat from the intake manifold and air supplied to it. Preventing heating of the air can be obtained for 5% more power. Instead of the 50 dollar pads brand Hondata, you can make your gasket for the intake manifold, of a material such as cardboard insulated (0.04 cal.thermal conductivity, ordinary cardboard 0.15) or optional.
Turbocharged cars usually use an aluminum intercooler that the air is cooled and compressed before it enters the engine. The intake manifold is also made out of aluminium, but since the cylinder head becomes hot during operation of the air intake manifold is heated to 50 degrees.
thermal Insulating gasket intake Hondata
It is noticed that for every 3.3 C (5F°) the density of air decreases by 1 percent. The higher the temperature, the lower the density, and hence the amount of air in the engine. And this means that fuel will be less due to lack of oxygen.
Using the DataLog was taken the temperature in the intake manifold with the usual padding and insulation. On the chart below you will see the difference the temperature drops about 10 C degrees, so did the bypass throttle to the heated coolant also does not affect the temperature rise. By the way if you look at the Type-R you will see that most of the sources (outlets) of the heat is missing, that is all the cooling going on inside the engine. At least the extra heaters in the form of hot hoses under the hood.
the Comparison charts, as you can see with the thermal protection on the intake, the heating is slower.
As can be seen from the graph, when the throttle valve is opened, the temperature drops slowly TK then air cooling. But when the throttle is closed, or you drive around town with a slightly open throttle, the temperature rises sharply. Youll need 10-20 seconds to open the damper so that the temperature became normal. For example, if you drive a quarter mile, the maximum power you will get only at the end of the race. Its physics, based on the air density in the engine from the temperature and pressure.
\ntheIf you decide to do the thermal insulation of the intake manifold, but the brand Hondata you is not particularly interesting, it is possible to make the gasket yourself. First you need to find the right material with a low coefficient of thermal conductivity — there are many reference books on thermal physics or materials where specified these coefficients. It is better to use paronite or polytetrafluorethylene (Teflon-4), as did Kyky-Pyky.
Example of a homemade strip Itasca on D14
the smaller the conductivity, the worse the material conducts heat, and therefore better isolates the two environments. Result conductivity of the three materials for example — less is better in this case.
themost of the strips Ive seen, is a fluoroplastic-4. Do not assume that he is on par with the stock box. First PTFE gasket is reusable, and is not deformed from moisture. The second spacer thickness is typically 3.5-4mm, 1-1 against cardboard.5. This means that the thermal insulation increases.
But we should not hold already on 4mm stud intake manifold has a length of just under the nut crepe;and. So it is not necessary to run specially for the PTFE 3 PTFE-4 copes. Purely visually, the engine is hot Honda hand hard to keep, but the intake manifold only slightly warm.
