Ahh, ok. Around the same boost I run then. Well maybe there was a problem with that weld/pin from the beginning?

+1 I'm running up to 21 psi midrange (peak) on my RBs and WGDC stays around 30-40. Just how much boost are you running with that N20 sensor?

Glad to hear you got the problem sorted :)

+1 LOL. Yes OP, please give it a try...... :cool:

Kollegga New VTT upgraded HPFP/Fuel rail is currently sitting in customs, hoping it clears next week. Time for testing E85 :P

Seriously? BMW here could care less, they even say it doesn't happen....

I wan't to move to the US. First we have to pay 3 times as much for the car where I live, and then when something breaks,...

So far $3000, but now I'm having what is most likely LPFP sensor issues. Had new MSD81 coded and installed and all 6 coils replaced. Only the cylinder 3 coil was dead, but since they all had 80k+...

I knew it, I was a believer from the start.... Awesome news. Hope mine will be ready to ship soon then, so that D can optimize my RB turbos for full E85 :D

I completely agree. I didn't know, but do an internet search and you'll see multiple cases, also fom comletely stock cars. Unfortunately, BMW in Europe doesn't acknowledge anything. They MAY give me...

I would tend to agree with the above statement.... :scared-eek:

Was driving along, accelerating onto the freeway and got massive misfires. didn't go away with engine stop/start, plugged the Cobb AP in and read the codes. 4 pages worth of "misfire, injector" etc....

Cool thanks Tony, I guess they've gotta come in before you can modify and ship :D

Anyway, I just fried my DME as well, so I'm currently waiting for another one of those. Didn't wan't to try a...

Any updates on shipping? :)

Cool. I'm pretty excited for this solution. Hope Tony gets the parts ready to ship soon, so I can start testing with E85 maps from D :D


Wonder how many already ordered, but I wouldn't be...

I've ordered one, and I will log with straight E85 as soon as I get it installed and Dzenno makes an updated map for me. Running E50 with RBs up to 21 psi now so far just fine with reasonable...

I agree, that's why I already ordered mine. Anything over E65 and the HPFP takes a dump with my setup (FBO + RBs + Walbro LPFP). Would be so nice to be able to just fill it up with E85 and maybe even...

Awesome, I'll send a PM. Looking to run 100% E85 with my RBs

Congrats to VargasTurboTech and ProTuningFreaks. This really is an awesome result, or rather accomplishment. Not only is it the highest whp on the N54 ever, but also a HPFP fix "first". That demands...

Well, I've been running E30-E60 mixes for over a year now, so I don't have any old logs to compare to. Running 21 psi midrange and 17-18 top end on RBs is no problem for the HPFP as long as the mix...

That's what my HPFP is also doing with E85 (well anything over E60 really), otherwise I'd be over the ~530 whp I'm seeing with the RBs now with E50. Walbro holding up real good though, so I really...

Awesome Tony. I love the way you approach this, it's really great to have you in the N54 world :handgestures-thumb:

Staying tuned for updates.

Great prices. I'm staying with my RBs for a while yet, but it's great to see this solution available for this platform, not married to any specific tune and very reasonably priced, considering the...

Congrats Tony and Dzenno/Jake.

Awesome results, very impressive for 91. It will be very interesting to follow the progress from here on. Even with the HPFP concerns there should be a lot to be...

Thanks :dance:

It's cold around here now, around 30F. I don't have IATs for the run from yesterday, as I was logging LPFP and something else in stead, but when I did the pull in 4th gear I started at 36F and ended...

Best recorded run on pump was 9.51 seconds, you can see it on "the other forum" in the 60-130 list, post #156.

So RB turbos + PTF E50 mix map improved my time by almost 2 full seconds. Not a bad...

Cool Terry, I think it's great to see just how my car performs compared to yours. All things considered, being just 0.2 s slower with a full weight 335i MT and no meth just makes me even happier with...
