mic Donating Members 1,725 Member For: 17y 2m 24d Gender: Male Posted 29/09/12 06:22 AM Share Posted 29/09/12 06:22 AM get an adjustable fpr and crank the pressure to 50 psi or so. 044 will laugh at it no probs. also as said the pump should be receiving 14v or thereabouts at idle. an extra pump would still be a good idea though I recon. u should see how much fuel jap cars need to make 400kw on e85 its ridiculous. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/82123-fuel-pressure-falling-on-boost/page/4/#findComment-1302159 Share on other sites More sharing options...

I dont think the average joe would tend to check fuel pressure too often.Like has been said the 044's are rated at 700fw/hp using petrol.As a rule of thumb the motor will use 30% more E85 than petrol @ the same power right?Im doing the math here and I can kinda see how the fuel pressure dropped off... though most likely im getting ahead of myself.
