[QUOTE="Fourcam380, post: 15684191, member: 185249"] Heads become less relevant when FI is part of the equation. Any design flaws like shrouded valves, small valve and curtain area, bad port angles are quickly mitigated along with and up to actual casting imperfections. NA the heads dictate potential peak HP. Intake, cams, exhaust etc determine at what rpm and how much of that potential is ultimately tapped. FI ultimate potential is dictated by the displacement or size of the blower or turbo(s) not the heads or even the engine. With boost the only task the engine really has is to hold the power not make it. Some great boosted engines were total NA dogs i.e. any mod motor. Going the other way with it a 8.0l W16 4v minus the turbos and with higher comp pistons only made 620-625hp but made 1000hp+ with oem pump gas boost. NA W12 was a horrific dog but the latest TT DI version will bang out 800hp crank Ecu only safely on pump gas. [/QUOTE]
