[Tigers] Engine Photos: Twin Turbo Car in Ariz

[Stephen Waybright]

The lost heat/power to drive big boost levels shouldn't be a problem, since there is still a lot of heat energy going out the back end of the pipe, but I would think that the turbo lag in such a set up would be incredibly terrible (HUGE). Perhaps in a V8, particularly for drag racing, turbo lag is probably not as big a deal as it is in a little 4 banger or for street, roadracing, or autocross applications.

Hi Kirk,
I've actually seen that a few times now. In its own way it has a simplicity.  You can run the stock exhaust configuration, you don't have to move something out of the way under the hood etc..  I'm not sure what is lost in power with the diminished heat at the turbo and then pressure losses going back all that distance back to the intake.  But, for a street car I kind of like the idea.  Maybe if fins were welded onto the long intake return tube it would become its own intercooler.  :-)
