Notta. I know this cause my partner had SC and myself NA twin app same hulls and he'd stop at every port possible to fuel up. More efficient??? Research how much hp it takes to get 900 hp SC.

Didn't matter how we ran either. Regardless I don't pay attention to fuel and doubt it will bankrupt me only having a 2 1/2 month season so either way I could care less. I run hard and when I need fuel I get it.

well... I run big power.. my boat is a big wave crushing bi*ch... however when I'm just in cruise mode 65ish/mph that's approx 3500prm... engines are content and throttles are way back... Roots blowers make big grunt down low and this makes for efficient midrange... however it's a nasty MOFO when the sticks are welded to the dash, this was my only point in the comment... I am an advocate for the supercharger!! BIAS for sure!!!

SB what did tunnel rams are those? I saw them on here long time ago. Sweet.

Btw FF. Good choice. The 2001 would be a great option for 4500 flange also. Glad t see you got that 2000.

I love the looks of those intakes, reminds me of the early Pontiac bathtub intakes that made tons of power, back in the very early 60s. just not the tunnel ram height!
