PSD vs IDI fuel economy

[BioFarmer93]

It will cost you more $$ than the extra mileage is worth + extra unwanted heat in the cylinders.

Not for a 7.3, you can build a very nice drycell unit for about $300. The burn is faster and specific impulse is improved, so less time to heat the head, cylinder & piston. I have observed NO difference in running temp. Do REAL research and testing like I have before you repeat other people's (intuitive but erroneous) opinions, so that ass holes like me don't have to light you up in public forums like this. Save the hate, I'm out.
