The cast pistons cant handle it. If you upgrade the pistons, rockers and valve springs you might have a chance. Otherwise several of us have proven that the 496 isnt a great platform to upgrade with bolt-ons unless you upgrade the internals.

You will see 0-1 mph if you are lucky.

I have also heard that, I have a couple of friends that has 300 hour plus on a stock 496 HO with this Procharger
one with 5,0 Psi and the other has 3,5 psi pressure. Both says that a lot depend on the hand on the trotle ;-)
Again it can also be that they have been lucky so far...
I am very unsure about this, so probably I want do it ;-)

Probably need to upgrade your drive and prop, maybe raise the x-dimension by fitting a shortie. Have you got full hydraulic steering? What size tabs are you running? Blueprinting the hull, tearing the cabin out to lighten her up..... Where does it end?
I would leave stock alone, everything I've read says the 496ho is a great engine if it's left alone. Just run it sensibly and service it, you'll get trouble free boating. That's why I bought one.

sounds good in theory. Simply bolt on an extra 125 hp, how easy is that?

Thanks for the reply ;-)
And yes my plan was to be all stock, have given me 3 seasons with care free boating
I am not a crazy speed freak at all, then I Would had another boat, not a Fromula 271 Sr1. Most of my boating are done at
40 mph 3600 rpm or slower and a Poker Run now and then. It would have been fun to go 70 mph + when I want to though ;-)
Now I am doing 63,6 GPS mph .. Mirage 23+ prop drive ratio 1:5
I have an almost new Bravo1 X drive and 280S K-Plane, No hydralic steering yet..
