Was watching some you tube videos of boosted stuff the other day, exhaust got cherry red almost instantly on a few of them. Know nothing about this stuff but what I have read. Page 62 of "Street Turbocharging" makes mention that schedule 40 weld els are adequate for most turbo applications. Goes on to say that for long term durability and strength at the high temperatures in a turbo application, it is generally recommended that schedule 40 or thicker be used. Considering it is going to take a bit of boost to do what you want to do it has me wondering how the thin tubing of a set of mild steel headers will hold up, as well as what effect that long tube from the collector to the turbo will have. Most, if not all, of the turbo headers I have seen have the turbo flange at the end of the collector. Again, I know next to nothing about turbocharging, just thinking out loud. I understand that there is more than 1 way to skin a cat.... I do know that years ago I helped a friend with drag car on a regular basis. His headers were Jet Hot coated, and you could literally grab the headers 30 seconds after the car had made a pass down the strip...might want to consider coating instead of heat wraps and blankets....
