BTW, my fuel system has an additional electric fuel pump and larger lines going to the engine along with the adjustable fuel pressure regulator and ported intake. This guy is doing a Crockett setup: http://www.hotboat.net/forums/showthread.php?t=98928 Thanks for the link. I will look into it....... |

I second talking to Tyler, very honest guy that builds real hp. |

The 500HP is overrated just like the black motors. I have dynp sheets to prove that...... The 525HP is underrated by a little. |

The 525HP is underrated by a little. Are you putting your motors on the dyno and installing the parts? I would love to see what kind of real world numbers you get. |

Hey dg, what do you think an entire FI setup is worth on the used market? Someday, I would like to go to 540's and I don't think this Merc FI system will handle it and will probably have to switch over to carbs.

I think your FI will handle 540's. Lingenfelter made 540's that were 585HP-595Hp and they used the same FI, just a different ECM calibration. |
