RB turbos

For those of you running RBs I have a few questions...

1) Which flash are you running?
2) How much boost are you peaking at?
3) if you have JB4, which map are you running?
4) Have you had any fueling issues?

Reason I ask these questions is because I am looking into RBs but would like to easier the midrange to 21-22psi. I already have RBs N20 3.5 sensor just want to make sure fuel can keep up.

if you are running a Jb4 you need map 6 and a customer flash by Terry.
If you are running flash only tune, you need a custom map

Unfortunately, after speaking to Terry I found out I would require more fuel such as Meth or port injection.

Is meth out of the question for you?

Yep.

Would rather just have the peace of mind and go PI.

You dont need PI to run RB... RB turbos have been out for years before PI on our cars and thousands have used (and still do) without PI

Sorry lol forgot to mention that. Right now on stock turbos I run E50-E60. I have the walbro 255.

My end goal was to make 500whp reliably.

Good luck! Let us know how it turns out. I don't think 500whp is out of the question, especially given what's happening with HP gains on the inlets. Can't ignore it.

Can't you make 500 reliably with rbs and FBO on just pump gas with a jb4?

What does a FBO 135i + rb make for power on 93? Roughly.

I run E50 on RBs pushing out 20-21psi and did not require any supplemental fueling. I have meth via the procede but the car runs fine with only the flash and the procede turned off. I have a Stage 2 Fuel-It pump though.

Pretty sure he means he mixes 50% e85 in his pump gas, which isn't e50.
