Hi,
what will a rubber/silicone do under pressure and negativ pressure.........
use as much pipe as possible and just use a rubber to compensate motion and to do a connection

Why do all FMIC setups use stainless or ally (i'm taking about the pipework) Why not use samco hosing or cheaper equivalent? Yes, I can see the appeal to the eye, but that's it? I would like to have a setup done quick and am thinking, whats wrong with silicon and or rubber (not sure what material it is) piping??? cheers |

Aluminium pipe is a lot cheaper than silicon, it won't bend, melt or flex like silicon. If you did this (and I don't suggest you do) you'd still need metal connectors and clamps for the bends. |

I think this could be quite an amusing project to use samco hose. Please video for our entertainment! Even better than the guy who fitted a header tank without a pressure cap. Time for me to put the kettle on.......

as sunny said the whole setup may collapse under vaccum. |

20psi x lots of square inches. I have a vision of a Celica floating above the traffic on a samco balloon. seriously though, after turbo should be mostly pressure, which will hold the pipe open, especially at high flow rates. I can forsee a situation where.nailing the loud pedal after a period of overrun at high rpm will suck the pipe shut which will even prevent the turbo spooing to blow it back open. |

Really want to go down FMIC route but dont want to spend loads.... what do I do??? Ideally, I would buy the core first, save then buy pipes to suit.. |

Doing it in Samco will cost double what it costs in hard pipes - ask Gary, his original FMIC on his st165 was all done in Samco with joiners and I believe it cost him a pretty penny at the time. Also every joiner is a weak point and potential boost leak location, if you did it all in silicone you would have 20+ possible boost leak locations, whereas a good hard pipe kit will only have 4 - turbo joiner, throttle body joiner and 2 intercooler joiners. Also silicone joins disrupt flow a lot more than a smooth metal pipe. So basically I can't see any reason why you would want to do it, I don't think there are any plus points! |

looks like you need to be patient mate and save to do it properly |

If you want a cheap kit I have a spare Evo 6 core and a brand new set of the eBay st205 pipe kits, plus a load of extra pipes and joiners at my folks place near Sturninster Newton - you can have it all in the cheap as I don't need it and its just getting in the way. |

as all above mate, if going fmic do it right or you might be less efficient than the cc. |
