33 Coupe Chassis 39        2/05/04

This is what it looks like clamped in place on a scrap piece of tubing. Now I don't need a full two foot piece just to protect those wires so I'm going to cut it but I have plans to use the rest somewhere else. Notice that I cut the clamps so they fit a little better. This is because the kit fits up to a 3 1/2" tube and mine are only 2 1/2" diameter which had the clamps way to long for my liking.
 

 

 

After cutting the material a little shorter, this is what it looks like installed. Notice how it doesn't fit tight against the tubing. Thermal-Tec recommends that you leave a 1/2" air gap between the tube and material to work best. I'll have to see if those wires stay cool enough when I start the engine up again. If not, I can always put the remaining piece over the wires themselves for some added protection. Not much room between the wires and tube ....now is there!! I may add some insulation to protect the power brake booster if it gets to hot so we'll see about that later too.

I had my exhaust apart the other day to add this insulation to both sides (top and bottom) of the mufflers. The reason is because the mufflers rest on the top and bottom of the chassis's X-member. What's the big deal you ask? Well after talking to my buddy Gary, he suggested that there should be a gap between the muffler and chassis so it wouldn't resonate through the car. I had bought this kit from Thermal-Tec which is made for insulating a starter but I was going to cut it into small pieces for what I needed. The kit comes with a piece of material that is 12" X 18" and is made out of the same stuff as the exhaust insulation is in the above picture. It also comes with a band of stainless steel that is 3 feet in length and five clips. What you do is cut the stainless band to whatever length you need, then slide a clip on one end which only goes on a given amount. Now you take the other end of the band, slide it through the other end of the clip and pull it tight. The band has small cut-outs in it and the clip has small barb-like teeth that fit into the cut-outs for a nice tight-locking assembly. 
 

 

 

What you see here is some clearance being added to the mufflers. I had to dent the can in a small area to make room for the insulating material to fit. The dented area that you see rests on the driveshaft hoop bracket which is 1/4" thick but because my chassis has only 4 1/2" of clearance and my muffler is 4 1/4" at the largest point, I had no room for my insulation. This gave me just enough room to add a piece on top and bottom.
