FMU Ratios and injector sizes
Can someone explain the ratio on a FMU.
If it is 12:1 and you have 6psi of boost this causes the FMU to raise fuel pressure to 72psi, right ? Is this 72psi in addition to the factory regulators 38-40psi ? or is this 72 psi total ? Also, what size injectors would be recommended for a stock cylinder head 302 running 6 psi,GT40 intake, 65mm throttle body, 73mm MAS, 1.7 roller rockers, 15/8 equal length shorties, and dynomax exhaust? Should I ditch the FMU and go with a tune ? What is everyone's opinion ? Thanks in advance. |
