EFA Posted February 23, 2003 Share Posted February 23, 2003 Caterham, in the roller barrel upgrade kit for the K supply a new fuel rail which take a separate non-rover fuel pressure regulator. To make this easy to install they fit it at the opposite end of the fuel rail and supply new fuel pipes which are too short as thy are designed for the std fuel rail.... which will also bolt straight onto the Roller Barrels. The std K regulator is marked "3 bar" and I was wondering if the R300 runs more pressure than this, or is this adjustable regulator just the preserve of the R500 and SLR racers? If so, what do they set it to as I need a very convincing argument not to fit the std fuel rail which will be a whole lot less hassle. Anyone got FP readout on their R3/4/500 series Stack?? In fact can someone who owns an R300 take a look under the bonnet and tell me if the fuel pressure regulator is at the front or rear of the engine......

Dave York Posted February 23, 2003 Share Posted February 23, 2003 Arnie, I set my adjustable regulator at 3bar and have had no issues over the last year. David Whoever said ... If it aint broke, Don't fix it... Just doesn't get the point! Link to comment Share on other sites More sharing options...
Peter Carmichael Posted February 24, 2003 Share Posted February 24, 2003 If you have sorted the access code for the map, fuel scaling is very easy to apply regardless. The standard fuel pressure, injectors and pump will be fine for Tony's R300-alike, so I would bung it together with a standard rail and fiddle it (if necessary) in the map. I sincerely doubt that it will be required. Link to comment Share on other sites More sharing options...
