Rising Rate Fpr w/ 380cc

[guitaraholic]

It's said 380cc injectors are good to about 240-250whp at 3 bar. Also 380's can flow enough for 290whp at 4 bar. Now yes you would need an ecu tune for this to work perfect, but,, what if you used a rising rate FPR. At 0psi boost, the fuel pressure would be at ~43psi. However at 14.7 psi of boost, the fuel pressure should be at 4 bar or around 57psi. This would seem to match about perfect, because 14-15lbs of boost (T-28) would give you around 260whp or so maybe a bit more, giving a little bit of head room on fuel. Now I know this isn't the perfect setup, but I would think you would have enough head room from fuel flow to be pretty safe.
Also, 4 bar isn't too much to run on injectors, yes I know once you start getting over 60 psi, things start to get a bit hairy, but 57 psi isn't that bad. This is merely an idea to give a nice alternative to be able to turn up the boost a little bit more and have the fuel flow and not worry about blowing a nice hole in your pistons. Also, yes upgrading your fuel pump is a must before doing this, preferably a something HP, like the Walbro 255hp. Because fuel pumps flow less as the pressure increase.
