Manifold Tech: SS Expansion and Turbo Bracing
Not sure if you need a turbo brace, rodends or bushings ?
First, convert the temperatures the brace is going to see from degrees Fahrenheit to Celsius. Just for the sake of simplicity, lets say the brace will see temps from -40 degrees F (winter) to 200 degrees F (summer), that will give us a delta T of 240 degrees F. Convert that to Celsius or Kelvin (its all good) and get 121 degrees.
Next, convert the length of your brace to meters (http://onlineconversion.com works nicely). Then, plug your length into the equation:
Delta L = 17.3*L*Delta T
Delta L is change in length of your brace in meters
17.3 is the coefficient of thermal expansion for stainless steel
L is the original length of your brace
Delta T is the change in temperature in Celsius (plugging in 121 for it will work)
If your brace is a foot long and the underhood temps get to be 300 degrees Fahrenheit, your brace will lengthen about 0.0025 inches, or about the width of six hairs lined up side to side. Rodends should work just fine.
Just to give you a little perspective of underhood temps, paper will start burning once temperatures reach 451 and most plastics melt between 200 and 450.
