For about 95% of peoples cars the answer is yes. The standard regulator holds stable fuel pressure and raises it in line with the level of boost pretty well so in most cases theres no need to change it.or is the nissan one good enough for the job
I still say it's a bodge. If you need to throw more fuel in, buy bigger injectors rather than trying to force more fuel through the ones you've got.At what level of boost or power would it be worth getting an fpr?
when, and only when it can't keep a stable pressure.At what level of boost or power would it be worth getting an fpr?
not if it's a shit one.spikey said:I guess a aftermarket fpr could hold a more stable fuel pressure?
problem with that is u have it set wrong ull either under or over fuel the engine.as said if u need more fuel buy bigger injectors.better to spend the money on them than try to save a few quid on an fprIf you were to increase the fuel pressure, would you not get a better spray pattern for more efficient combustion? I only ask as modern engines can have fairly high pressures which i thought was to get a better burn and for emissions.
If you were to get it setup on the rollers so that the map can be adjusted for the increased pressure would it be beneficial? Either way it would have to be setup. I would always fit bigger injectors, just getting some info anyway...problem with that is u have it set wrong ull either under or over fuel the engine.as said if u need more fuel buy bigger injectors.better to spend the money on them than try to save a few quid on an fpr
Set it up wrong,bore wash the cylinders and fuck the engine
Does the stock fpr not have a spring that could go soft or collapse as well?One of the most common problems ive seen/heard with them is the spring collapsing or going soft thus reducing fuel pressure.in all honesty as with the more experienced members have said stixk with the srock one unless u absolutly have to uprate.
