Yeah i don't get it. Can't break 55 with just me in it and a 1/4 tank of fuel
|
Have you checked the timing? Is the trim limit set too low? TomZ is our mpi guy, maybe he can give you some places to look. |
How do i go about contacting him?

Here's a picture of the boat. Still need to get better ones yet |
He has already replied in this thread so you just go back to that post and click on his user name. Choose send PM when the option comes up and introduce yourself. He is a sharp guy with a couple mpi 502’s. |
Oh gotcha. Thanks

Im sure you guys remember a while back when user zackevans6.7 was looking at this boat.
https://www.facebook.com/marketplace/item/618002172053281/ Look at the block and verify that is has 8.2 on it. It isnt impossible that someone put the mag mpi intake on the 330hp 454. We have seen stranger things happen. Your speed is dead on what a 330hp engine pushes these boats with a 23 mirage plus at 4800rpm. That works out to a 21% slip which isnt too bad. I dont want to seem like an ass, but I dont want you to be mislead either. The 502 mag mpi was a 435hp 8.2(502 ci) engine. That power would easily push you into the low to mid 60s with a full tank and a few friends on board. |
I saw that boat for sale on FB. Looks like a Gen VI 415-horse 502 Mag MPI. Formula says the 390-horse 502 Mag (carbureted) should run 61-62 with a 23P Mirage... the 415 should be right there.
It would be helpful to know some specs on any of the changes made during the rebuild. It is also very difficult to troubleshoot without a Rinda Techmate scan tool. If you plan to keep the injection set-up, I wholeheartedly recommend buying one. You'll be lost without it. Search for Rinda TechMate Pro Sent you a PM Vsyx. -Tom |
TomZ i sent ya a message
