Jellybean Posted December 14, 2014 Share Posted December 14, 2014 (edited) Hey Read a few threads and cant find the answer Some cars are running less than 700hp Why are some cars fitted with Top Feed fuel rail and injectors as opposed to Sard 800cc side feed high impedance injectors so will drop straight into the stock fuel rail without the need for a resistor pack on a Jap spec car. What take the extra expense of the Top Feed fuel rail ? If you are going for more power , I am sure you will keep the current setup for a few years Would you remove the Fuel pulsation damper on the Sard stock fuel rail drop Ins? RHDJapan has a sale on for 800cc @ 350 euro for 6 Edited December 14, 2014 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
bignum Posted December 14, 2014 Share Posted December 14, 2014 Firstly sard arent the best injectors to use, out of 6 brand new i had 3 leaking fuel straight through,gave starting problems!! Also you`re better off feeding the rail both ends, this can be done with a stock rail but again its more work, Then when you switch to top feed it opens up a much bigger choice on injectors.
