Thanks for reply. I did a full hydr setup on the steering but no trim tabs yet. I'm not quite sure but I think my gear ratio is 1.5 and not 1.36...

Thats a stout number for NA 454s at 5100rpm. You sure the dyno didnt have an overly optimistic correction factor ? My buddy had a 31 bullet with 600hp 509's, turned 26p bravo 1 props to 5400-5500

6yr old thread.

He wrote this page before this:

I know 4400 RPM is too low... So, I just have got a new 22 Merc Bravo1 4-blades prop. What should be the approx. result?

That would be a good comp in a way in regards to my 28' challenger. 454's on roids deal and made 480hp. Turned 25p 3 blade mirage 5,600-5,700. Bravo one 1.5's. Prop's were tuned up a little with an edge on them but ran 78 plus. Weight was undoubtedly less than 31 bullet but not lite.
