    Thanks! Not sure on the N54 though, as I haven't fit anything on one yet.

    It would be nice to have that much hp under the hood. Not really realistic for my DD though.

    Thanks for all this information, @[email protected] where can I look into purchasing this kit for my F30 335i? My current setup is 2012 F30 335i with VRSF Downpipe, Chargepipe, FMIC, BMS intake and VF Engineering Stg2 Hex Flash. Stock turbo and stock fuel.

    LOL! This is fucking classic! They tried the same thing on the N54, after their claimed 700WHP turbos wouldn't make 700WHP without dyno spikes. These guys are such BS marketing artists its insane! Can they produce these 4 "blown" motors? How about a graph from ANY of the 4 making 600-650WHP. How about a log? Well since they never post logs of any of their exaggerated numbers, I can imagine we wont see any logs, graphs, or basically any proof of this. BUT hey guys the N55 is a LOT weaker than the N54. Want to know the solution, put our shitty flowing, failure prone Stage 2 turbo on it, and make 450WHP. Wait were they or were they not selling these turbos are 550+WHP upgrades like 6 months ago. Now that better flowing, more efficient set ups are released like this kit, our twin conversion, all of a sudden the N55 is weak, and the PS2 should be run at 450WHP to save your motor. How long until people start calling these dudes on their bullshit? If this gets edited or deleted I am going to be annoyed Tyler. They made these claims, have the back them up with a single fact. A single log or dyno, pictures from these blown motors, ANYTHING to prove they are not just using BS scare tactics to sell turbos...

    No actually I have killed not a single motor with GC testing. Not one. I killed a bunch of weak stock motors testing Stage 2, and 2+ long ago. We have not actually blown up a motor "testing" in a long time. I killed one that had low compression, and a knock when I bought it by desensitizing knock sensors, and running it as hard as I could in the 1/2 mile. I have yet to break a built motor even with over 900WTQ. 700WTQ by 3000RPM. I have spun a bunch of hubs, and bent like 800 valves though.

    Still interested in this for E-series N55 for a few of my clients. Any ETA on E-series dev? I also have a couple F-series clients that will be looking to upgrade soon as MHD F-series is available.

    Have you had any issues with Boost Creep on the EFR turbo?

    I've come to the conclusion that there is a certain percentage of the population that will probably believe these unfounded rumors, until there are more of us running big turbos on N55's. It's one thing to claim a hp limit on the stock frame N55 turbo, as the backpressure has to be to the moon when creeping up to the 500whp mark (I've shown cutaways of the stock manifold, the xsec area is 1/3 of that of a T4 flange... the manifold was designed to spool damn near off idle, there's a reason that manifold is not used in any of the higher power platforms going forward), it's another to claim a limit on the engine as a whole, as some of us are already proving otherwise. We'll be able to come back to these posts in a couple years and find humor in it.

    We have E series ready to go, have a few out there already, so let me know :)

    I haven't had any issues with boost creep, I'm currently running boost by gear without issue -

    3rd- 22
