Added Pro-Drive EFI & heads worked by Pro-Drive to a 35 GTR. Heads were decked .040, port work, and valve job. Motor has a stock exhaust. Before - 3800-3850 RPMS - Top speed of 26.2 MPH After - 4300-4350 RPMS - Top speed of 30.5 MPH - Compression is right at 152-153 psi on both cylinders Saw a steady gain of 4 mph, while maintaining a quiet exhaust. Boat is big and heavy for an 18x48. I was surprised to see 30 mph. |

what was the before compression? how many hours and year of engine? any porting/polishing done to intake manifold or plenum? stop talking about EFI - until I get motor! |

| Post subject: | Re: 35 GTR w/ Pro-Drive EFI & Pro-Drive heads |
so you didn't have to do any polishing or "cleaning up" inside intake manifold - and the ports lined up with head ports - spot on? |

Correct, didn't have to touch them. |

Have they wrote a tune for a motor with an exhaust? Is the sensor the only addition to the stock muffler? Nice setup |

if your fuel cell is mounted forward in the boat do you need a "pusher" fuel pump by the tank? |

If your cranking compression is 150ish and your heads have .040 of decking removed, you have a problem. Cranking compression on stock heads is 150ish. Heads decked .040 should be 170-180. |

My compression with iron mountain heads was 150 on my old PD. I will do a compression check on my current stock Pro-Drive with 3 hours on it for a cross reference tomorrow. |

I want to say Blue said his stock PD was 130 and 135 PSI, after decking .050 and some deshrouding he is at 160. |

Pretty sure these are deshrouded as to why the higher numbers. |

Now on my dual rig with cam and heads I'm seeing 175/180 on one motor and 155/150 on the other. Wonder why the different. I think they were decked. 035-.040 |

Just put a motor together with the heads decked .045 a little while ago. Compression 160 and 160. PVT cam and stock size Manley valves. 2 weeks ago i had some other heads decked .045 that went on a stock bottom end and the comp was like 160 and 150-something. My shits .055 with a PVT cam and 182 on both. I believe stock range between 135-145 depending on what kinda shape the motor is in. |
