ARIZONA SPEEDA & MARINE UPGRADE?
 

Has anyone running a procharger upgraded to the MEFI3 computer and bigger injectors that ASM sells as a kit? If you did was there any performance increase or is just a reliability issue? I think it runs around $1200. Any input would be appreciated.

I think the injectors on the 454 & 502 are pretty big to start with. I hear they use an injector larger than on a 500efi. Was your mefi 1 reprogrammed?

Ken, I'm not busting in on your thread but I didnt know if I told you. The mefi1 was reprogrammed.

That's ok Shoe, I knew that but I was told that I could upgrade to mefi3 and larger injectors and pick up a littlte and be safer on the engine. I'd like to know if someone has done it first and if it was worth the money. Oh yeah, I posted some pics in the baja sec. in 272 opinions. Check it out.

I would ck with Mark with Precision Marine 504-469-7463, He has done alot of the ProChargers.

I would do a search on AZM there are some negative threads on them :eek:

Ken,
I agree with Strip. Mark at Precision Marine has had some input already on your motor and is very knowledgeable with the Prochargers and their programing. I would highly reccomend him.

You need to call Mark at Precision Marine .

I have a friend that has the Baja 272 with the 502 mpi procharged and Mark did the computer on it. The guy has been running for 4 summers and is running low 80's MPH.

He is one on ARIZONA SPEED & MARINE ecm problems

Re: ARIZONA SPEEDA & MARINE UPGRADE?
 

It's a '97 Baja Boss 272, 502mag w/m3sc Pro charger and a L&S stern jack. It ran 82mph GPS before last summer. I freshened the engine last winter and added lightning headers redid some of the fuel and oiling system plumbing and had my 30p prop "bravorated" . I thoughtI would pick up some speed but I ended up losing 3mph! I've got it narrowed down to the prop so I guess i'll start with that this year. Can this boat be improved by altering the X dim? I don't even know what the measurement is on this boat.

Re: ARIZONA SPEEDA & MARINE UPGRADE?
 

Oh yeah, I did replace the drive gears w/the newer "thicker" gears. The old ones kept flexing and cracking thrust washers. I was lucky they did'nt explode.With the 30p bravo it turned 4900 rpm by my tach. With the prop bravorated it turned 5100 but slowed down on top end by 3mph.I'm fairly certain the tach is off 200rpm.

Re: ARIZONA SPEEDA & MARINE UPGRADE?
 

Kenny thats some good speeds . I like the new color on the engine ,brightens it up.Maybe Mark can help ya out some .
