montanajr Posted March 20, 2008 Share Posted March 20, 2008 Hey,You know how everyone says "run 3Bar fuel pressure for 1Bar boost", I'm getting the car setup on a dyno, but in order to get it there on 1Bar I wanna run 3Bar pressure obviously. Now, is it as simple as just turning the nut on top of the FPR while the cars off, turn it on, check and repeat?Also, when people say 3Bar - do they mean 3Bar at idle or 3Bar when the car is rev'ed? 'because as you lot know, when you rev the car the pressure jumps at. Abbott (who I bought the fpr off of) has it set to 2.2bar idle and 3bar load, would I want it 3bar idle and well, roughly 3.8 bar under revs?Oh and, what is standard fuel pressure just out of curiousity?Help would be lurvely,Cheers.

StarletRick Posted March 20, 2008 Share Posted March 20, 2008 its 3 bar with the vacuum pipe taken off of the frp. to do it youll need a fuel pressure gauge. and if its the sard one you have you just twist the nut on the top untill you get the right fuelling. easy peasy Quote Link to post Share on other sites
montanajr Posted March 20, 2008 Author Share Posted March 20, 2008 Got a gauge; yeah this one has a nut on top as well. Why with the vacuum hose disconnected though? And does the car need to be off when adjusting? I'm assuming so.. Quote Link to post Share on other sites
StarletRick Posted March 20, 2008 Share Posted March 20, 2008 no mate, the car has to be running. its hard to get fuel pressure when the car isnt on and you take the hose off so it is 3 bar at atmosphere. i personally think 3 bar is too much. i had mine running at 13 psi on 35 psi fuel pressure, which is about 2.4 bar... you dont have to boost the shit out of the car on the way do you? just drive nicely and set it to 33 psi Quote Link to post Share on other sites
montanajr Posted March 20, 2008 Author Share Posted March 20, 2008 But...I wanna drive it about for a bit, feel what 1bar is like, then get it setup! lol. And yeah I know you need the car on to get pressure; but you could turn it off, adjust the nut, turn it back on and check - then repeat Quote Link to post Share on other sites
Squeak-Glanza Posted March 20, 2008 Share Posted March 20, 2008 Good question here am just about to be fitting my Sard FPR and was needing to no what to set it to, so you say 33psi is a good setting for them untill i get it all set up as I've got a adjustable actuator to go on aswell and a front mount.

StarletRick Posted March 20, 2008 Share Posted March 20, 2008 you can adjust it with the car running mate. Quote Link to post Share on other sites
-Harry- Posted March 21, 2008 Share Posted March 21, 2008 But...I wanna drive it about for a bit, feel what 1bar is like, then get it setup! lol.Good idea! maybe cracked pistons will make more power. Does anyone know what psi the stock FPR runs. Im running 300hp atw on stock FPR. I recently overpowered the walbro pump so Ive added a bosch 044 as well and think ive overloaded the pissy return line and upped the fuel rail pressure which has thrown out my maps.

montanajr Posted March 22, 2008 Author Share Posted March 22, 2008 Don't worry, selling the FPR and FCD now. Don't wanna risk damage to my engine and rather get it setup with an ECU, piggyback or possible SAFC. So for now, its no 1Bar for me! Check for sale section if your interested in either bits..
