When turbo'ing my 3SFE engine, what if I use a 2:1 rising rate fuel pressure regulator to help correct fueling for the increased air flow.
With a 2:1 RRFPR, the inline fuel pressure will increase by twice as much as std as boost increases and the regulator sees boost pressure. So, effectively, the 32psi odd will increase to 64 psi odd at 1 bar as the increase is linear. |

The standard fuel pressure is around 43 psi (0 boost, 0 vacuum). So, if you boost at 10 psi with a 2:1 rising rate fuel regulator, the new fuel pressure will be 43 + (2 x 10 psi) = 63 psi. 63 psi is big. You will need a big fuel pump to be able to flow the needed fuel at that pressure.
Look at "Wolfkatz" fuel pump pressure tests on MR2OC.com for more info. It's doable, but you will be limited in boost by your fuel pump and injectors. Hope to help Sam This post has been edited by pitcelica: Feb 18, 2010 - 10:13 AM |
