my classic will be running round about 350 bhp hopefully when its all back together im having a parrallel fuel rail ,walbro and 550 cc injector's and im just want to know do i need an uprated ruel pressure regulator ?

 

i run 360 on mine and its on the standard fpr

 

yea ive seen quiet afew running that kind of power and having a std on i just dont want to waste like 200 quid for nothing .

 

0.8 * injector capacity is a good guide. i.e. 400 bhp on std injectors, to be safe at that figure I fitted a Fuellab reg, and it cost more than £20 !


LOL

dunx

 

sorry mate eddited i did mean 200 pmsl .
if it was 20 id have one lololol .
