all,
Ok might have to post elsewhere in here but I have a question that might have been discussed to death in here but even so, I can not find threads with relevant info.
How do I get to approx. 400 hp on the Mercruiser 383 MPI reman engines????
I cant get the engines in a bench for testing and remapping (im in Europe....) but I can send the PCM555 to Whipple for remapping. I was planning to do this to get it configured to 91 oct (we call it 95 here) but before I do this I was thinking I could put in a new cam and possibly a new intake manifold? I hear this is where these engines seems to be loosing out some power? nothing crazy, all I want is 400 hp each side so I can keep my 23" Rev4 props but get from approx. 4900 rpm to 5200 plus if possible. Also I need to crack the 70 miles mark (im currently 67.....) im not looking for higher numbers really and certainly not willing to go BBC. I love the weight balance in the boat as it is now and I get on a plane faster than my brothers Outlaw 25 with 550 HP Raylar.
Personally I think the exhaust systems are not a must but I could be mistaking. I just don't see the value for money but obviously like the looks! With thru hull exhaust already I don't think a gain would be in there.

Then have your props labbed by BBlades.
Doing both will for sure get to crack 70mph.

Wow what a refurb. I had the pleasure of being on OSO member Paul Buckeners 28 a few times and they are a hell of a boat. I miss riding on that boat. He is located in the UK and is pretty knowledgeable engine wise. Try shooting him a pm

thanks again for all the nice comments.
Griff, yes good point, did not think of the labbing. Maybe get the prop's to BBlades also should give me a few more revs combined with the mapping.
I did write a few mails back and forth with Paul B but been a while. Think he is running with 496 but if he is into engines in general might be worth to ask for a bit of advise.
