why two blowers
 

Why do boat engines have two blowers and why don't race cars or super street races have that intake setup? I'm new to all this. I have one more ? Why do all header joints have a rubber hose in the joints. What is the purpose?

the rubber hose is used to transfer the jacketed water from the header to the tail pipe.

I think height has a lot to do with the two blower setup you don't necessarily need to cut scoops in valuable sun pad space. Youre talking the quad rotor Whipple setup like on 1075's?

I dont have any rubbers, 2 kids,full jacked dry exhaust.

not an expert,but i think 4 small rotors are much easier to spin than 2 big ones...less inertia

your post count is 666 get rid of it, :faint2:

too late....i'm already possessed

Giant lysholme type screw blowers weren't available.

The inertia statement is possibly true, but not the reason.

because its for a boat and more is better:coolcowboy:

Compact size and spinning 2 blowers slower takes less HP and creates less heat.
