Ive found out that with a carb that this is easy. I just dont have the rods and crank for it. I had a MpI intake and tb at that time and wanted to get started. Then I sent the manifold to Tomcat for an Rtech mockup and thats where it ended. Now I have 2 toys that need EFI! I was thinking about using a Megasquirt on my car and if it works maybe on my boat. Anyone reading this ever use one?

My Dad has a 540 being built for him right now that made 1000 hp with 8 psi boost. It is under 540 Rage in the Nordic forum, I would post the url but have not reached 15 posts yet and cannot It is going in his 2005 Nordic Rage. There is a video of the dyno run on this thread as well. The engine was built by bobl who posted on here earlier.

I think you had better buy some 1/4 inch alloy plate and very carefully cut it with jig saw and fit it under the engine. Make sure you cover all the fiberglass under the engine without leaving any gaps. That way when the engine grenades a few seconds after you hit full throttle on your first run, you wont send the by now white hot crank and rotating assembly completly through the bottom of the boat. The alloy plate should limit the damage enough to keep you afloat long enough to get back to the ramp so long as you are not to far offshore. Good luck. Jas

Im not goin for 1k. I dont have the internals for it. My original post was to determine that if I spent the money on the mercruiser MPI unit that it would supprot the extra HP. I didnt want to buy efi stuff twice. But I hear ya!

I started reading your post thinking where in the he|| is there another 1000+HP 540 that in a Rage, or that you were making it up until I realized who you were! Hi Brian! Here's the video of the 540 on the dyno bobl built for TXInstigators Rage. He was able to get boost down just enough to get HP down to about 915 which is how it went back in the boat.
Video of the Procharged 540.
Down in this thread he posted the dyno sheet after the 3rd pulley finally got boost down.

It's an M-3 He is running around 6 psi of boost now and actually hit around 925 hp at 5600 RPM Motor is designed to top out at 6000, the Dyno was having a problem loading the motor so they were not able to get that high. BTW I live Vicariously half way across the country through my Dad's Boat LOL. Hey Jim how's it going have you made it out on the lake yet, I know you guys have had a couple of nice weekends.
