second pump hey whats up guys first off im running a 347 with a gt42-76 turbo i have 75 lb injectors and converter and i am running a single bosch 420l. my goal is to have the fuel system capable of supporting 950rwhp. i will also be running a meth kit.
supposedly the bosch 420l supports between 600 and 750rwhp on an FI application (ive heard different things from different sources) so i will have to run a second pump.
i have a sumped fuel cell with two outlets i was planning on running one pump from each outlet and the tieng them. the car will mostly be doing street driving (no street racing lol) so most of the time i will only need the power of one pump so when i want to race or go faster i would just flip a switch of install some sort of relay that atuomatically comes on at a certain point
my question was which pump should i use as my second pump ie should i go with another bosch 420l or with a walbro 255. i know the walbro supports 500 rwhp on an FI setup but would i just add this number to the capability of my bosch420l? the other concern with the walbro 255 is the big psi drop as load increases.
i would really like to run the walbro seeing as my wallet is hurting from the rest of this build lol however i do not want to skimp out on a vital part of the car. but i only want to put what is nessecary to reach my goal and do so realibly
