Seems to be a massive difference in costs of fuel pressure regulators - is it worth spending the extra on an expensive one, or is the cheap one fine?
Bearing in mind I wont be going for mega power, just mega reliability lol.
What one do you use?
ive got the cheaper "looks like a black top but isnt black" version. (not to be confused with the shorter max power ripspeed style FSE) it works fine, has held pressure steady for aslong as ive had it on the car. but as gary pointed out and as the old saying goes, buy cheap; buy twice.
once the demand on the FSE increases with the undoubuted future mods ( ) it will surpass the capablility of the cheapo, get the blacky.
well, as mentioned above, steve greenald likes weber ones, and he has done back to back accuracy tests on the rollers with a black top and a sfx type reg, he still prefers the wber, reckons he's never seen one go wring and thwey stay super accurate, its what i use, and its only 50 quid, and no matter what people tell you, they are adjustable, you just need to remove the blanking plug from the top to get to the adjuster
fse still gives startup issues, i would go with a fixed fpr and adjust the fuel map if i did it all again. you can get fixed fprs with swappable heads for different pressures, but at 100 quid a head they aint all that cheap lol
you will see what i mean if you do a cold start first straight off the key and second by priming the fuel pump a few times 1st
