What /6 is Best For Forced Induction 170, 198, or 225?
The cylinder head is still the limiting factory. When I said it all goes out the window when you pressurize it is because of the wide and varied parameters introduced and variables that go with it in how it operates.
He also doesn’t have the luxgury of a 4 valve head in his slant 6 so why would you even introduce that into the conversation? It seems that it was done to make me look dumb.
P.S. My Grandfather inlaw worked on those in the beginning before Chrysler decided on turbo cars thank you very much.
I have more stories than you have and had hair.
Next....
LOL, I think You should ease up there Bro', Your statements seem contradictory. But I think We agree & don't realize it, ..mostly...
1) "The head is the limiting factor"--Yes, exactly why I brought up the 4-valve head, it doesn't have to be, it could just be O/S valves & porting or whatever...it's more flow.
2) "It all goes out the window when You pressurize"--What "all" are We talking about? The example I gave shows the relationship of headflow vs displacement w/= boost.
The OP is talking an identically prepped head on two different size engines, the smaller one will rev higher at the same boost & turbo capacity, that is all I'm stating.
Depending on how well the system is designed and responsive the turbo is, the effective RPM band could be a
lot wider with the smaller engine, if that is needed.
3) I never introduce anything here to make anybody "look dumb" Sir, My intention is to see that the OP gets accurate info as much as possible, I don't need the former.
4) I'm glad You have a relative that was part of Mopar's history, and I hope You have those stories written down to keep & share, peace...............
