AFAIK, most never fuel injection systems use much higher fuel pressures in their FI. I'd imagine this is to achieve better fuel atomization for fuel economy. Since I have tunable FI I was pondering what it would take to increase the runing fuel pressure and wether it would be worth it.
OBVIOUSLY the fuel supply/return lines should be upgraded to steel for safety. Would new injectors be necessary? The FP regulator would need to be replaced. What else? |

We set the fuel pressure on the EFI engine we build at 3 bar, and injectors are sized to work with the 3bar pressure
Whether its worth the expense to upgrade all the hardware to be able to run higher pressures is tough.. |
