https://cimg0.ibsrv.net/gimg/www.off...28764c5a6f.jpg https://cimg9.ibsrv.net/gimg/www.off...10e39155de.jpg Did alot of testing on a bone stock 500, the crazy plenum a guy sent me to test WITH 525 tb added more tq and hp to a stock 500 than anything else that you can easily "bolt on" (NOT talking cam or heads), 500s have too small of a plenum from factory and small tb that is a slight restriction, Modded (cam, heads etc) the stock FA quickly becomes the biggest restriction after the TB |

In back to back testing with closely monitered AFRS and tuned back to same afr Ive seen the 8 to 12 hp gain on 500s, also seen the stock 500 FA reduce hp even on a stock motor, Smitty

I acquired a 525EFI Upper/Lower to swap onto my 502MPI Mag. It is complete, less Injectors, Im wanting to toss a Pro-charger M3/M4 (future growth) on unless I can find a complete Vortech kit, Just going to Run a Remote mounted Inner-cooler to simplify the Mounting system. If I cannot get the SC in place prior to swapping on the Intake set-up, Without the Cam, will it hurt anything, I have a few contacts to do the tuning adjustments on Mefi3? Im not sure I'll have the ability to Pull engine to swap Cam, it's currently at the dealer, Lastly, having a pair of Innovate widebands added, one to each manifold. - Thanks in advance. Cant seem to find much detail on this subject.

Jason at MDG built a 532ci 500EFI (4.6in bore 4in stroke) Stock heads and cam. He used the stock 500 EFI intake and it made 525HP 620ftlb. He did another pull without air cleaner, 537 hp 620ftlb. Installed the Hardin marine mono blade, 545hp 620 ftlbs. All pulls were done with all accessories and water.

With the conversion, only modifications neccessary beside some mild wiring reconfiguration is the IAC motor, ill just make it remote from a hose, to use the GM style unit thats controlled by the MEFI3, I believe the 500 & 525 use a pintle type Ford style unit. I'm doing all homework possible so I have all parts in hand when I do installation, dont want to disable the boat while at dealer, when they're done the Hull and other repairs/modifications, its going to be watertested and fitted with an appropriate prop. So hoping to get everything installed and running, Supercharger included, but im working with a 6 week time frame. Thanks |
