Mild 383 build
Shorty, I apologise for interrupting your thread but you & the readers are being fed absolute bullshit by '273'' & Newbomb Turk with their claim that increasing area of the piston creates more push on the con rod. They know it is wrong but haven't got the guts to admit it. They are getting force & pressure confused, two different entities, high school physics stuff.
First, just look at the common sense [ or lack of it...] Going from a 4" to a 5" piston gives more than a 50% increase in piston area....& according to these two that translates to 50+% more instant HP. If it was that easy to get that sort of HP increase, with no penalty anywhere in the rpm range, wouldn't people be building engines with HUGE pistons?????? Of course, but that is not how it works....
Turk, you got Bettes's book..... pity you didn't read it..... Turn to page 145... & learn something.
Below is p.145.
Power & piston area. Notice in the formula piston area bottom line is divided into the top line. That means the resultant power piston gets smaller as the piston area gets bigger
