Excellent post Tony!

All the stuff we are dealing with here is based on the concepts you presented above.

The release of energy by mass reduction happens on the atomic level (and obviously not in the IC engine). Thats a good thing as the energy in the mass of an ounce of gasoline would probably turn the engine block into liquid (or completely annihiliate it) in nanoseconds!

E=MC^2!

I keep going back to this comment, Rocky and I've got to admit I don't think it's true. Sure, diesels don't rev as high as our motors, but they're positively huge! Wouldn't a 6 liter motor at 3000rpm flow about the same amount of air as a 3 liter engine at 6000rpm? Also, why do they put huge 3" inlets on an intercooler that doesn't flow? I've also heard from some people that at a given HP level a diesel requires more air than a gasoline engine and with some of these diesels making 300 or more HP how can they be inadequate?

While I admit that the specific intercoolers the pictures were posted of don't look like they're designed for flow, they certainly aren't representative of all diesel intercoolers.

my thoughts exactly. hopefully, i'll be able to give you a comparison of my cummins diesel cooler vs the xr7 cooler.

Hey all,


If the high flow spearco flows best, but doesnt cool as well as the internal fin coolers, would the use of a CO2 or Nitrous sprayer on the external fins help create the colder charge? Or maybe a alcohol water injection towards the end of the track to help with the possible detonation and knock retard....

i took my 90 shelby daytona to the track earlier this year. 12 psi on boost controller, cut muffler off, and no air filter with auto ran 16.00 at 86. put descent sized front mount on ran again and got 15.61 at 89. pretty good gain considering i only bought it off my friend for $100.
