| and I favored the cast.. It felt strong and more responsive. I know its just butt dyno.. but you know what I mean. Wouldn't have a SS tubular (much thinner walls) bleed more heat than the cast iron? I know that SS does hold heat very well for the thicknesses of what it is. From what I have learned (I may be wrong).. is that by having the cast iron.. it may not flow as well compared to a tubular setup.. but since it retains heat so well.. It will help keep the energy in the internals of the manifold, forcing the heat to its next/easiest path to cool (heat-->cold) , down the turbine and out the exhaust. I know we do not want all the heat to be held inside the manifold, I remember when talking to Mike Smith before about swain coating my manifolds, he recommend against it due to it pre-maturely aging the cast iron because it is somewhat supposed to bleed. But the bleeding from a SS tubular manifold would allow alot of heat/energy to be bled through the material and theoretically the exhaust gases will lose some velocity/pressure that would normally go through/into the turbine housing.
