I am planning on around the 6 grand mark also. 540 going in a Activator 27. Was planning on procharging but dont want to do the blow through carb thing so decided to go roots carbed.

I would vote a roots supercharger is harder on the drive all other variables being equal. My opinion is based on immediate boost at all rpms where a centrifugal supercharger has to spool up. I understand centrifugal is a more efficient supercharger but if you want results without waiting roots will instantly assault your drive train. Ask me how I know! This performance sure does get expensive

I've been running 700 HP through a pair of bravos for about 500 hrs. The drives are original circa 1992. Over 1100 total hours on the drives, never opened up. I'm easy on and easy off and it I air it out it's not intentional. Don't get me wrong, I use every bit of power I have and I beat on it when someone makes me do so. It's all up to how you work the throttles.

I did build a drve for a guy guy with a 25 Baja, 950 hp. It too had X gears In an IMCO case. It made it through his Poker Run, and that’s all he cared about. I was honestly shocked it stayed together. That’s a lot of power for a Bravo.

Centrifugal chargers seem like they’d be easier on the drive because they make power higher up in the revs when the boat is up and loose, but they make so much power that they require huge props that struggle to get out of the hole loading the drive even more. I’ve heard stories of drives living forever in rough water but blowing them up in smooth water with the constant relentless tension.
Moral of of the story: you’ll have to pay to play once X amount of HP has been exceeded no matter how you achieved it.
