i want to get a adjustable fpr becausei think im lossing pressure durring start up and closed loop driving why you may ask?
i have decaped stockys ever since ive done that the car is hard to start (flow tested at 799cc) (puff of black smoke when started) could be not atomising the spray proply due to loss of pressure and floods the motor???
(oly someties) also have a walbro 255, when i drive or just letting out the clutch it does a quick hesatiation and my ideband leans out for that split second ( note this problem was there before i decaped the injectors, but after i changed my feul pump)
if i do get a new fpr do rails have to be changed? or can they withstand higher pressure
and how do you actually adjust it ? i want to get a sardd fpr
piping lenght does that matter a well?
i understand factory one is 1:1 ratio 15 psi boost meaning 55psi feul pressure for eg whats the ratio on the sard from factory? without adjustments
ive been told im losing feul pressure and im leaning towards the same thing because ive checked everything eleese lol beside feul filter?
car runs fine other than that
things ive checked
- the tune it self (cranking pulse width injector timing etc etc)
- leaks vaccum and boost
- fuel line leaks and rails
- fuel pump operation and changed the filter on the pump
i do let the pump prime everytime before i start it or could this problem be fixed siply with a new oem fpr?
