When people install front mount interoolers, why does all the the pipe work need to be done in steel? Why can't it be done in PVC or ABS plastic pipe?
The reason for asking is that the induction manifold on my (and all) MY07 GT is made almost entirely from black ABS plastic. This plastic is connected directly to the top of the metal block (Well heads really).
On the positive side:
I would expect the difference in flow resistance between plastic and metal piping to be similar if not slight better.
It is appears to be able to handle the pressures that we are talking in a relatively stock system.
PVC and ABS piping is cheaper, and I would suggest a little easier to work with. When heated it can be bent into some pretty interesting shapes and joining is much easier and it is cheaper.
It provides better insulating properties.
On the negative side:
There is a heat issue with the piping - Vinidex suggest that "The recommended maximum continuous operational temperature for UPVC pipes is 60°C. This limitation refers to the complete pipe wall being at 60°C and would apply for continuous flow of a fluid at 60°C." Source: Vinidex Technical Note VX-TN-8C This heat issue may be resolved by the inclusion of heat sheilds and other insulation on the outside of the pipework.
It doesn't look anywhere near as good as a lovely welded and polished stainless steel induction system. Mind you, you could paint it or even get it chromed...
It is nowhere near as strong as steel pipe work.
So, am I out on a limb, off my rocker, nuts or onto something. I suspect that it is the former as opposed to the latter but I'm interested to hear your thoughts.
