Title: 4 bar FPR
Post by: Dalo Harkin on 19 April 2016, 13:05

looking at my spec would a 4 bar FPR make any difference or should I just stick with the standard 3 bar, I'm replacing it anyway as its been on the car from new and while I am replacing vacuum tubing can do it then

I will also be adding a fuel pump at some point soon so will be upgrading that and the injectors to the S3 ones along with the 3" MAF.

4 bar gives an increase in fuel. Im changing mine for a 4. Little increase in power.

Extra fuel pressure won't make any difference. The only time you should change it is if your mapper asks for it

4bar FPR just kills fuel pumps.

Get yourself a DW pump or walbro and you'll be fine
