Message "Did you ever produce the calaculations I asked you foron your theory that using stainless steel for hardpipes is a terrible metal to use because they will transfer more heat to the air entering the engine and therefore produce less power?"

I never said it was a TERRIBLE metal, I said it was less then ideal because of the amount of heat it would retain - 2.5 that of mild steel and 10x that of aluminum. You asked for a solution to a 5-dimensional problem with constantly changing variables. Although I do have the software at work, and the know-how to solve such a problem, it isn't the most trivial of problems to solve on the back of a piece of paper. It can be done, and mark my word it will be done, but other things have taken presidence over your little challenge. Have you done a stress analysis based on temperature fluctuations, heat cycles, CFM, before you back-up and release a product? Of course not, some things just aren't practical. By the way, are you using A-554 or A-269 stainless for each application? One has good ductility (and hence better overall properties) then the other because of a full anneal... thought you might want to know that...

"Do you know how much time the air passing through a 4" long piece of metal pipe has to absorb any heat from the pipe itself? "

Yes, based on 500CFM, it has about 1/1000 of a second, over a total surface area of 16 cubic inches.

"Do you know that aluminum requires constant attention to keep looking respectable and stainless could care less?"

Please, don't insult me with such a ridiculous question. Could stainless really care less - or is it just a property of the material? Anyway, my hardpipe kit will not be made from SS304 or aluminum, just FYI. Any more questions, or must I continue to defend your meaningless challenges?
