Wether an engine is running under vacuum, under atmospheric pressure or under boost will not affect pulse waves taking place as inlet valves open and close, which means that equalling flow between...

Well yes, thanks.
It seems they were made in the same mould, with 944S heads slightly opened up on the inlet ports and the water passage with the block machined open.

It seems this was posted on the 928 board? 928 4V heads are different from 944S/S2 and 968 heads, with smaller, rounder than oval inlet ports and apparently optimised for peak flow through port...

How long is piece of string?
Any 944-based engine running "continuously" 500 rwhp will blow up sooner than later, and a 2.5 8V will not even get there unless totally sacrificing "everyday usability"...
