pprrado 0 Posted August 7, 2006 HI, I HAVE A CORRADO PROJECT, OF A TURBO, BUT ITS CARBURATED, IM TRYING A DRAWTROUGH TURBO SYSTEM, MY QUESTION IS, DO I HAVE TO PUT THE TURBO ABOVE THE ENGINE? SO THE GAS COMMIN OF THE TURBO FROM THE CARBURATOR STILL GETS THE ENGINE WHILE THE TURBO ISNT SPINNING, LIKE THE FIRST TIME IN THE MORNING WHEN URE GOING TO STARTED.??? :?: :?: :?: :?: :?: THE ENGINE ITS A 1.8 8V Quote Share this post Link to post Share on other sites
Henny 0 Posted August 7, 2006 if it's a draw-through turbo, the turbo can still be anywhere in the enginebay (preferably as close to the exhaust outlet of the head as possible to reduce lag) and the pipework for the carb feed just comes from there as normal. The idea of a draw-through turbo (or supercharger for that matter) is that they allow air to be pulled through them when they aren't making positive boost pressure so the engine can be normally aspirated until the charger spins up to make boost... You HAVE to use a proper sealed carb specc'd for turbo use though, else it'll just leak the charge from around the spindles when under pressure from the turbo and not run properly...

If your using draw through, you can use any old carb as the carb doesn't have presurised air in it as its before the turbo. Trouble with draw through is you have a really long path from the carb to the engine and you get fuel drop out. Not sure i'd be too keen on a draw through system on a turbo as the turbo inlet side can still get very hot. Draw through is more common on superchargers. Having the turbo blow through the carb means you don't get these problems but you then need a sealed carb. TBH, for all the hassle with getting carbs jetted right on a turbo i'd just stick mappable management on it, such as megasquirt. Quote Share this post Link to post Share on other sites
