bosch tt pump and single -6an line from pump to fuel rail -6 an to afpr to stock return. Safe hp limit? For 2jzge na-t in my mk3, Will run a second pump and another-6 later on for more hp after bigger injectors (550 now)...
hp limits?
- Thread starter suprastupid
- Start date
Should be fine for over 600. I am at 510 crank HP on all stock lines with E85 (30% more fuel than 91 pump) Running a deatschwerks 300lph pump
I've been told multiple times by people running anywhere from 600-1000whp (2J) to not trust a single pump (Walbro, Denso TT, Bosch, etc.) much past 500whp.
I'm inclined to believe them, not to mention the majority of setups I've seen seem to abide by that rationale.

! lean run under boost will ruin your entire week if not year...
I always take what I need then double it when I spec a fuel system.

I believe the opposite, what if you have a 2 pump system and one of them goes out? Your car will still run, and you probably wont know that ones out cause it will start up and drives fine. It wont be until you get into boost and you cant hold fuel pressure, that means High afrs, and adventually a "kaboom" some where down the line.. let me tell you iv personally experienced this :icon_eek: If you can afford it go with a single high quality high out put pump system just my two cents
I dont want to max out my injectors (550cc) or push the fuel system past its limits. I am using a stinger 4424. I will add an additional bosch pump and another -6 line an upgraded fuel rail with dual feed ad center exit and bigger injectors after I get more money and want more hp. I will have a good tune as I plan on getting it tuned at boostlogic..

Who ever said the point of if you have 2 pumps and if one fails. I dont think they thought of the part of if you have 1 pump and it fails. Atleast with 2 you have a back up.
And as long as your buying new quality parts you really shouldnt have a problem.
And if you have some good tuning software, you could prolly create a fail safe.
