Been searching around for a buddy of mine and his 08 gt500... his mods are ported blower..2.50 pulley ..xpipe.dual pass h/e and an jlt 127 ........stock fuel Sunday we went to tune with kevin macdonald (what a tuner great guy) Issue he was having is the fuel pumps dieing up top rpm starts around 5800 Commanding 14v but his alternator (3rd motorcraft he's installed)..is dieing out...now I've heard stock pumps even without a bap should support this hp level which was 585hp We're looking at 2 different altenator an bnr 200a (ebay store) or another reman motorcraft since he bought the upgraded pulley so it won't over spin... Gonna send some data logs to kevin once we fix the altenator .... and hope it dosnt die up top Now ive done some searching and found the 5.0 pump is a 290 flows lph ..13 gt500 uses the same pump but 2 of them....has anyone use this pump on the 07-12 gt500
Just add a kb boost a pump. Also make sure the battery is fully charged and if its older than 3 years get a new one. One thing that helps kill alts on these cars is batteries on low volts. I've been through 3 alts too. Now I keep my car on a Battery tender all then time since the car is not a daily driver.
dont like bap..would just like to upgrade pumps ....i get a good price on the 13 gt500 pumps...might order them and see if theyll drop right in or work with alil modification
Change your fuel filter like VAN said, happen to me, shut it down on dyno at 580hp then change filter and added a Tvs now makes 630 with stock inj and stock pumps, no BAP.
Cant remember where I saw it on here, but I don't think the 13 pumps will be a direct replacement for the older cars.
Fuel filter is not even a year old... I know the stock pumps are good...its the altenator not suppling enough power...need to upgrade that first. ...but I was talking to my buddy to find larger replacment pump for safety or fuel system and run e85
buddy just ordered a bmr altenator 200amp for 195 shipped on ebay.com..... im sure its not a true 200 amp but hope it holds voltage up top..
