I do like the fact that stock it is now rated for 87 octane. Just need a dual program--one for cruising/trips and one for high octane/boost max power :cool:

Without changing the cam you will need more boost for the same horsepower, which will shorten the life of the engine.
There is a reason why Merc uses a different cam on the 700 SCI |

250hp and lots of $$$$$:D
If you ever used the vessel view or system view Race Edition you do not want to miss all the information anymore On the 600 the boost is controlled by ECM , so you can reduce boost at cruising RPM which saves fuel and helps your Bravo Drives |

All Mercury supercharged EFI motors (except for 575) have boost control. Air fuels are very good stock so tune is good, boost/timing is very conservative.
Dustin How much HP does your reprogram make? |
Thanks for the info, Dustin and everyone. I've been wanting to know this stuff about the 600sci since it first came out. Looks like it is a pretty good all-around package with aftermarket help :D

Yes, if you want more than 675hp, you'll need a cam change or intercooler change. As I said, I have cam and pulleys in stock.
Dustin Do you already have a reprogramm for the 600 SCI PCM Module that works with or without a bigger cam and more boost or do you exchange the smartcraft system to a MEFI system like you do on the Mercury Racing 525 EFI Whipple Kit and loose smartcraft monitoring and guardian systems ? If yes please show some Dyno results |

Hey guys,
Just finished testing my PR 42 with Dustin's stage II kit for the 600sci and was blown away. With stage 1 I picked up 4 mph and was expecting maybe another 4 mph with the second stage which would have put me at 108 mph with Bravos...........was I shocked when I saw it hit 111mph in a relatively short distance with 2 aboard! As a matter of fact I didn't even play with the trim and found out it was actually tucked in a bit. With the same 6 blade Hering props I went 100mph stock, 104 Stage I and 111mph Stage II. Dustin's sh*t works!! |
stage 1 ecu reprogram?
stage 2 ecu cam and pully? |
