Someone asked me what kind of heat shield material I stuck on the bottom of my xb seat and airbox. I can't remember who, so hear it is anyway: http://www.jcwhitney.com/autoparts/ProductDisplay/s-10101/storeId-10101/p-5170/c -10101/catalogId-10101 I bought my from these guys: http://www.thermotec.com/distributors/distributors.asp?loc=na xbolt12 | ||

I meant HERE it is not H-EAR!  xbolt12 | ||

I'm sure it's not as effective as heat blanket material though. I'll bet it would work great stuck to the inside rails of the frame to deflect engine heat away from the gas and frame. Unfortunately, I did not buy enough to do that as well. xbolt12 | ||

Maybe you could answer this question. If you use reflective heat material to deflect heat from i.e. gas tank, seat, airbox, then how does the extra heat get removed from the bike. By heating the seat, gas tank and airbox there is a lot more surface area to cool the bike down when the heat is absorbed into these areas. So if you have reflective material all over your bike does the heat become contained within the engine causing it to heat up faster? Might be a dumb question but I don't understand how heat reflective material works. | ||

Yeah Enduro. I think thats a valid point. But I don't know which would cause more negative effects on performance. I think you're correct though in your logic. To me, AIR INTAKE TEMP, would be the most important number to be chasing. I don't think fuel temps seriously effect perfomance, though I may be incorrect. Like what you're saying, the heat emitted by the engine is being reflected back onto it and thus could cause higher engine temps. Hmmmm... But is it possible that the transfer of the heat back and forth twice would allow it to be swept away quicker? I don't know. | ||

Liquids that evaporize cool down significantly. I might be wrong but I would think that's the reason why a richer mixture results in a cooler engine (ie, more fuel evaporizing). Now, wouldn't hot fuel result in a leaner mixture, because the higher the temperature, the larger it becomes. I don't know. Isn't that why MDO prices fluctuate by temperature? | ||

Hot engines with a cold fuel charge is what you are going for. It doesn't really matter if you cool the air OR fuel... As long as you are trying to cool them. I believe that cooling the air will give more improvement, but both need to be cooled. I wonder if an fuel-cooler would be a good idea... | ||

Fuel Cooler. Hmmm.... already thinking about that one. Put an active cooler in the space where the servo motor used to be. As for the temperature rising in the engine, I doubt it would to a noticeable degree. The fan should simply do its job and pull the hot air out to the rear of the bike. Besides, the thermal transfer into the frame is pretty slow anyway, so I doubt it is an effective heat sink in any fashion. xbolt12 | ||

They way I see it......hot air generated by the engine is sucked away by the cooling fan, sent over the shock and out the rear of the bike. 99% of the time I am moving on my bike so the air is just escaping as it normally would. The hot temp air is just "deflected" away from my seat and back into the airstream of the blowing fan and then out the back of the bike. If, and I think it would be minimal, the heat barrier causes the engine temp to rise any this would just bring on the cooling fan earlier and start this cycle all over again......just the way I see it.......Odie |
