Merc 6.2 MPI want more HP

I am looking for 5+ MPH. 2004 Formula 292 Fastec with 2/6.2 MPI`s. Has anyone done much besides procharger etc.? Like headers etc.? What is best mods to get max Hp and MPH?

Re: Merc 6.2 MPI want more HP

You are not going to be able to get much gain unless you get rid of the factory EFI on that engine. I've done some work on them and it's possible to get another 80-100 HP with head and cam changes, but you have to go with a carb or aftermarket EFI. Headers will help a little bit, but not 5 MPH.

Or you can SC it, but would not recommend a kit without the proper ECM calibration. Motor also needs an oil cooler, only has a 4qt oil pan, no cooler from the factory.

Thanks,
