So.....As many of you know its winter here in michigan, im getting extreamly bored.So I made this little gizmo http://i34.photobucket.com/albums/d106/jrcgaf364/Copyofxmas2005001.jpg

Its purpose it to help prevent heat transfer from my pipe to my shock. I took some tin cut it to fit then put some of that heat tape $hit from the back of number plates and attached that to it using wire and sewed it on. I also put a piece of cloth on the part that wraps aroung the shock as not to scratch it.

any suggestions feel free......just an attack of sever boredom since they thought A$$car was better than supercross.

Doesn't aluminum do poorly at dissapating heat? So, it would actually hold the heat from your exhaust and possibly act as a frying pan under your shock. Maybe? I mean, I know guys are using carbon fiber as it cools rather well and dissapates heat really well...

I almost think wrapping it in aluminum foil would be better since you're fighting radiation heat. If it were convective heat, then I would agree with the other guys, but you want a shiny surface to reflect the heat rather than soak it up.

If you measure temperatures at the shock with and without the shield, you'll notice there is no difference. Well, not enough for it to be a problem.

Hence the reason why factory teams don't bother.

The real issue here is that the two don't touch, and the bottom of the shock (the cap) above the pipe is a good size chunk of aluminum, surrounded by a large aluminum casting filled with a gas that takes in heat like Donald Trump takes in the homeless.

If you want to insulate something, put it between the carb bowl and the pipe. Or even better, insulate the bottom of the fuel tank.

well the reason i even thought about it is because i have a white bros. E series and it sits closer to the shock body than the stock one. Just a thought i was bored....

i recently wrapped the pipe from the powerbomb on my header back to the muffler can with 2" header wrap hoping to reduce carb/intake temps, i suppose it can't hurt the shock either. i won't really be able to tell until summer though :thumbsup: in theory it should help,looks kinda funny :thumbsup: i was thinking about doing the bottom of the tank with alum duct tape,would it be worth the effort?

i dont know^^^^ I was just thinking maybe i could go a little longer in my oil service intervals....I get it changed about 3 times a summer.

Damping in a rear shock is the containment of energy which is converted into heat. If you really worked that shock, perhaps your exhaust pipe would help cool it down. :thumbsup:

BTW - This is not to be confused with something that works to that of something that would sell. :thumbsup:

While I agree in general that the shock probably generates more heat in operation than it absorbs by radiation from the exhaust , the cleanest thing would be to have taken a roughly triangular sheet of stainless and bolted one point of the triangle to the midpipe mount bolt. Then roll the sheet up and over the midpipe so that the side opposite the bolt is parallel to the pipe, and between the pipe and the shock.

Incidentally, for the gentleman who asked, no, aluminum is not a poor dissipater of heat. In fact, it absorbs, conducts, and radiates heat exceptionally well, which is one of the reasons this whole thing is somewhat of a non-issue. The shock body is a relatively large mass of aluminum, and it would be extremely hard for the pipe to heat it significantly. But aluminum does make a good heat shield, and that's what most car companies surround their exhaust systems with. What makes it work is the air gap on both sides. It is also true that stainless steel is an even better material for making a heat blocking shield from, simply because it doesn't conduct or radiate heat as well.
