I wouldn;t hesitate a minute to procharge a 496Mag 3.5 psi.... remember Mercury used to warantee their 525SC for one year back in the 90's with only 3 lbs of boost.... 3lbs won't hurt a thing on that motor..... |

Not even a close comparison; especially when you consider the fact that hypereutectic pistons continue to get more brittle with use. I broke mine without any boost - |

No doubt there are several owners out there who can get away with this and in my estimation (for what it's worth), here's what happens:
Lots of guys add on extra mods etc and NEVER really run the boat hard. They wanna push it hard for about 20-30 seconds and see the GPS top out. Most of their use is cruising and rpm's below 4800. But a guy like me who spends & spends to get the power - I'll ring that b_tch out and buy 3 or 4 tanks of fuel @ Havasu in a day. If you play with it and enjoy the performance you ain't gonna run it long with boost before you have to tear it all down again. Not being negative nancy but I know that engine well. Respectfully, DON'T be fooled by the fact that you feel as though you don't hear from the guys who had "good" experiences. I've had lot of guys off this site call me. We talk about it for 45 minutes. They go off in a direction.. And then I get another phone call 3 or 4 months later. The only real defense in the idea of how you "never hear of the good experiences" might only be provided by the fact that few boaters ever join this site per-capita. But if you are a very sensible user, why not put the charger on it - - - Eventually everything breaks anyway no matter how you build it. :ernaehrung004: |

i think if you're the kind of guys that runs wide open all day (not that many,even if you pretend to be one),you dont buy a 496 to start with

Thanks for the input. Wont do anything for a while and am just doing rearch on future power inprovements. After what i have read and the peeps i've talked to it does seem to be a crap shoot on forced induction on a stock 496HO. Even the retailers i have talked to state to stay away from the 5psi models of any supercharger unless you upgrade the internals so i was just curious what the consensus might be for a smaller 3.5psi unit and reliability. I have 93 octance fuel available and dont rag my boat out. Just looking at the possibility of adding a little extra umph for occasional needs but mostly cruising at a desirable mph and rpm without holding the throttle down without major upgrades.
On another note, why would procharger and their retailers keep a product in production and sell it if it has such a bad rap in blowing up engines? Does anyone reprogram ECU's for procharger usuage? Just wondering. thanks |
I would think that if 90% of 496's with a Procharger were grenading, this forum and a lot of other forums would be blowing up with people complaining. jmo
