TECH: The Fuel Pressure Dampener

A few things.

It would be interesting to see fuel injector transition maps of a stock fuel delivery system before and after F.P.D. deletion.

It would nice to compare those transitional maps to maps of a modified fuel system. I assume the transition between larger injectors would be more radical due to their larger volume.

Steady fuel delivery means more perdictible tuning.

I'm sure a faulty F.P.D. has been the source of tuning headaches in the past, and will continue to be untill an alternative has been brought to the table.

Since the original design is pretty lame, we should devise a plan or test to manufacture an aftermarket F.P.D. or see if possibly adding more than one F.P.D. would help smooth out the primary/ secondary transition, if there is even a problem at all (which I'm sure there is)
