Registered: May 2002	Re: 3sgte group A fuel rail Sun, 17 April 2005 07:08 can I add somehting here...there are 2 issues I have observed in building high performance engines, including lots of 3S's.The first is structural failure of the rail from getting it too thin. I have only seen this once from a back-yard "rebore". It almost impossible to keep a long drill central. There are plenty of "large bore" rails around. Unmodified, the rails are capable of pressures well over 100psi/700kpa. next is bad fuel flow to one or more injectors. As indicated this happens when monster injectors are used on a "small" rail, and the internal losses mean flow progressively drops off away from the feed. These losses increase with the square of the pressure. Central feeds do not always fix this as the loss from the fuel hitting a wall at the T junction, are equal to metres of straight pipe. This is a basic hydraulics issue. The "best" I have ever seen is a properly dedsigned central feed with a "Y piece, coupled to a large bore rail. maybe this is food for thought for some of you.
