who is running FBO+METH+ RBs?

i get my RBs on monday and the car will be going for surgery the following weekend.

Im trying to find some data regarding:

what type of e85 mixture people are running---

fuel system upgrades (inline walbro or in-tank walbro 455)---

meth settings (additive, nozzle location, how many nozzles) ---

what map (jb4) are you using?


maybe we can all post our settings/mods here and try different things.

1) No E85
2) No Fuel System Hardware Upgrade
3) Nozzle is at the elbow before charge pipe, One DO12
4) Use Procede, run upgraded turbo map and backend fuel flash via OFT

93 Octane, 100% meth, about 19-20PSI in mid range 16-17 at top end RPM. Probably running around at 480 whp.

I believe Terry has a backend flash that is equivalent. It may be loaded by Bavarian Tech cable, or some other means. Originally i think he had something loaded by COBB, but not sure that is still supported. I have not kept up with those developments.

I have rb's, don't run meth but love e85. I put 8 gallons of e85 and 6 of 93 pump. Trying to come out with an e60 mix. I run a 20psi map with the rb's and it pulls like a freight train. I have a walbro 255 inline too keep up with fuel demands but it's not doing it's job. I've put 110 unleaded race fuel in and used the
20psi map and the fuel pressure is better. Expensive though.

thank you guys for the answers.
i have been running full e85 since last summer without an issue using walbro 455 setup 3.
meth, i run two cm10 nozzles, one before the ic, and another right after the ic before the charge pipe. after i added meth, the second nozzle actually, my stock clutch barely kept up with it, i felt it pulling a lot stronger in the highway. after the second nozzle i had to keep my additive at around 50, the car felt like it was gonna blow up at high speed/rpms with 60+ additive lol.

i think im gonna run some logs with e85 only when i get the rbs in, and go from there. run some logs, see how things look and start adding meth slowly. i have the 2.2gallon tank from bms but i have to fill it up quite frequently since i added the second nozzle. i bet there is no more carbon buildup around my valves anymore lol.

also, for those who are running RBs, did you get the Thrust upgrade? the turbos i got don't have them, but the turbos are still sealed in the bag and everything. im thinking about sending them back to Rob and having him install the thrust bearing upgrade.

I trust Rob's comments on the thrust upgrade:

Its pretty much a waste of money. However there are some who run around believing it converts a turbo to an everlasting device, so for those people rather than trying to convince them otherwise I just offer the parts for them.

before my rear RB turbo took a shit, I was running a 7 gallons of E85 + 100% meth on a single CM10 (FBO).

No fueling issues at all. Trims looked great. You could get away with a E33 blend (5 gallons of E85) but anything more than that you'd need either an LPFP upgrade or meth.
