SHO6GTH Posted February 9, 2014 Report Share Posted February 9, 2014 I own a 2008 Shelby GT here in the UK and have had the car Supercharged by Roush UK. It was their base conversion giving a mild 450hp. At present the car uses the Factory fuel pump which i have concerns about once i start using the cars ability and higher rpms. I have a new Ford Racing M-9407-C50 190lph fuel pump available, so should i be fitting this? Any advice from other owners with direct experience would be much appreciated.

sgt1864 Posted February 9, 2014 Report Share Posted February 9, 2014 I know the Roush kit (450hp) say you don't need to upgrade the fuel system but to be on the safe side I would upgrade to that pump or just add a KB boost a pump. There is also a wire upgrade kit for the stock pump that reduces cycle pump time by 10% and increases fuel volume, it made by S&H Performance. Go to s197.com there is a lot of good info to read on supercharge fuel system upgrades with stock 3v bottom ends. Link to comment Share on other sites More sharing options...
Kevin Patten Posted February 9, 2014 Report Share Posted February 9, 2014 Any 4.6l 3v putting out over 400 HP - I recommend going with the FRPP M-9407-GT05 dual fuel pump . I've put it on a customers Roush 427R with the upgraded blower/CAI and seems to be working well . JMO Link to comment Share on other sites More sharing options...

twobjshelbys Posted February 11, 2014 Report Share Posted February 11, 2014 I'm not positive but I think my Kenne Bell on the Shelby GT came with a Boost-a-pump. I also am pretty sure it included upgraded fuel injectors. Link to comment Share on other sites More sharing options...
