Hey guys I am new to this site, but not to cars. I do have a couple of questions though about the 05 mustangs. I have a 2005 Mustang
GT with a fully built bottom end, cams, C&L intake, and most importantly a custom turbo kit with a 78mm Benita Turbonetics turbocharger. My current fuel setup is primarily stock, with the exception of my injectors being 80# Ford Racing, and the M-9407-GT05 fuel pump setup. Last year I made 575 rwhp on 14psi, on E85, in 85 degree heat. Now I am wondering what is the limit of the GT500 fuel pumps? Also, what is the limit of my overall fuel system? I am looking at possibly just putting fuel rails and a BAP in it, but at the same time my goals for the year are to increase my boost up to 21psi. Any thoughts?
I have had a number of foxbody cars and the fuel system capabilities in a fox are clearly much different from those of the 2005 mod cars.
