A 540 with good heads and mild hydraulic roller will make a conservative 600 HP. Adding 50% with a blower is also a conservative figure. Yes, it will break your Bravo drive, so go with the Konrad ACE.

The Konrad package uses our supercharger system with pullies and EFI program for 800 HP @ 5200 RPM. We sell this system separately and one of our customers has already changed to smaller blower pullies for 900 HP. Idles like a 500EFI.

This package is very friendly, idles like a stock 525 with nice docking manners. I'd rather run a blower and have a more user friendly boat.

Here is a picture of my 509's. Thanks for the many replies. I'm going to do some more homework before I make my decision. I'm thinking of going naturally aspirated with the best available parts. I really want to stick to hydraulic roller so I don't have to adjust valves.
