Thread: Got my turbo

Tweet

Matt, maybe a turbo for a 3.8L V6 is a bit big for a Falcon engine? What is the size of your Falcon engine? It will still work but only after you get into an rpm range that puts out enough exhaust gas to turn the turbo over real fast. I recall seeing a dyno curve for a Corvair Spider with a factory turbo that had almost no effect until about 3500 rpm and then the HP went almost straight up. I think what you are looking at is almost no improvement at low rpm but a drastic jump in power as the rpm goes up. Some folks call this turbo lag. Usually the idea is to put a turbo from a smaller engine on a larger engine then you get an instant improvement at low rpm. On the other hand I am familiar with the economics of rodding and "free" is a very important word in economics. On the bright side, you will probably be able to maintain the usual good mpg of a Falcon six most of the time with a reserve power if you decide to keep it in a lower gear a little longer. There are several good books on turbochargers and the one I have emphasizes matching the turbo to the displacement of the engine. I would still put it on if I were you but you may not see much difference at low rpm.

well isn't a turbo made to get power as the rpms go up anyways..... most turbos dont kick in til about 2500 anyways.....
