Ouch, sad but true.

Just for clarification; I have also spent alot of money on stupid boat stuff, so you're not alone Timmay.

I Disagree, Blower Motor 700HP range is easier on the drive then a NA 540-598CI Engine. N/A with those cubes are stump pullers with tons of torque. Compare a DYNO Sheet from a 454-509 with a Blower on it versus a 540-598CI NA. Look at the Torque numbers and what RPM that torque is being made. NA make big torque throughout the RPM bands that most of us consistently boat at like ( Cruising speed). Blower Motors are only making that big torque when you have the sticks on the dash and making the boost. Either packages can be reliable. Just my 2 cents

It's better to have it and not need it than to need it and not have it, so what are you waiting for? http://teaguecustommarine.com/em0011...lue-34973.html.

Build or buy something designed in the last twenty years http://www.edelbrock.com/automotive/...rcharged.shtml

Supercharged LS 416 (720 HP & 695 TQ)

That's the info I was looking for earlier . Ty

Once you go blower, it's hard to go back to NA. The torque diffrence is night and day and if you like a seat of the pants feeling, it's hard to beat. Blowers gerenally pull until the sticks can't be pushed forward anymore while that last 500 rpm in a NA takes a little bit to get there.

If I was starting from scratch I'd probably build a NA engine in that power range because it would be a lot less expensive than having to buy a pair (in your case 3) blowers. If I was working with what I had, I might go a totally different direction.

Procharged with a Bravo XZ drive may be the most economical. Boost/Torque does not come on till 2500 ish Rpm. By that time hopefully your on plane.

Build a blown LS motor. Get the same power out of a much much lighter package!!! Plus they sound plain SICK!!! Heck, my N/A LS boat motor that is pretty mild made just shy of 600.

Forget the Bravo, The question was NA or Blown, And when the water is really rough. Torque is where its at, Not Horsepower.
So the answer is Cubic Inches NA

great info here guys! I see for base big low end torq N/A is probably the way to go till cruise speed without hammering, and if you want the fastest to top speed, blower will pull all the way up till max rpm

nice info!

BUT !

None answered to the question, apple to apple in HP, do they cost the same to build?

again, I'm not repowering, just discussion for my curiosity! and maybe others curiosity too!
