    well... i mean yeah of course custom make tubing and put a turbo anywhere... but a turbo needs heat to be efficient... that's why turbo manifolds get a close to the exhaust port of the head as possible... putting so far away won't do any good... you'll just have a turbo...

    I do agree on how mpg can improve. However My bud did it to a Subaru, and increased mpg by 6. Now mind you he even said if he's foot is in it constanly then no, but that should be common sense.

    P.S- Yes internals are being done at the moment on a back up motor.

    I'll come up with an equation and plug in the numbers later. The air would be around 50% cooler actually.

    What kind or internal upgrades are you doing? You're getting the stage I universal kit I assume.

    LOL, we have another off topic thread again.
    Who would think you will see a turbo thread under the topic "Header" :D

    It's not "Heat is good for turbo", actually it's "Heat is good for exhaust gas".

    In the exhaust side of turbo (is it how you call it?), you want to keep the exhaust gas keep as hot as possible cause:
    Hotter gas = larger volume = more gas flow = turbo spool faster

    In the intake side of turbo, you want to keep it as cold as possible:
    cold = more condense air

    In this catback (or just header back) turbo designer. Yes, you can get lots cooler air then the traditional turbo since it will need to travel a really long way until the air get to the intake. But the down side is the turbo is too far away from the engine compared to the traditional turbo.
    By the time the exhaust gas reach the turbo, the exhaust gas is cooled down already so the turbo will not spool as fast compared to the traditional turbo.
    I can see a very huge turbo lag from this design.

    The exhaust gases should still be hot enough to flow rapidly to drive the turbo yet far enough from the head to cool the air charge going to the motor. It's a unique design that has the best of both worlds.

    It is a neat idea, but the cost of the universal system is about $3000 without intercooler piping and fuel management. Now thats a bit costly unless you decide to fabricate something yourself then it really wouldn't be a bad idea. I like it. If you already have a header and you want to keep then why not go with a similar system. The header on my 1980 Corolla was $280 bucks and buying a new turbo header can run me from $150 to $500. Besides the look of my Doug Thorley looks really cool. Maybe I can salvage that! Anyway I like the idea! It just gives me something to think about.
