But, anything in the way of forced induction will be a boon to the breathing of this engine, and that's what it needs; breathing capacity!
Bill,
After your 5 page thesis, I think we got it. You like turbos.
Maybe time to let it go ?
Johnny,
Maybe time to agree that normally aspirated is never going to get the job done with this 170 cylinder head on a 225.
That's what we're up against, you know.
If you can find an acceptable way to cut 1,000 pounds out of an A Body (like Guzzi Mark did), then yes, the turbo is something best left on the workbench, but for the rest of is, it is a way around the strangulation caused by those small ports and valves.
Torbos are just ONE means to an end. A supercharger or nitrous will work as well, I think. I just used turbos as an example of one way to skin a cat. Not the only way, for sure.
If I haven't made my point by now, I never will... so, you're right; I need to give it a rest... and will.
I hope to see evidence, someday, that you took all this into consideration and have some 12-second timeslips from your slant 6 car as evidence that you took advantage of the benefits of pressurized air in that inline motor... 'cause it's not that hard, nor expensive. I think.
Good luck with whatever you decide, and thanks for the conversation. You have some great-looking engines!!!
