    10-12psi is suggested for most applications. In situations where back pressure appears high and boost is dropping below target despite PWM maxing out, then you'll have to increase it as needed.

    Yeesh. I was looking at potentially a CPO 2012 to 2103 X5 50i for my wife. After all this I'm leaning away from it now. Back to looking at Cayennes! -Rich

    I remember how careful I had to be in parking garages to make sure I didn't set off alarms. Definitely no way to be low key in that.

    Did they change the label on Eagle Rare 10? Could only find the black label (in the back) one. Agreed, good for the price.

    Hey i've checked and the IP you provided isn't blocked by the forum and my host checked and it isn't blocked by the server. You're sure that is the IP you're trying to access the site from? If so, I'm out of ideas.

    The issue with the notification bar expanding on zoom in on mobile is now resolved. Please verify. That's the most cost effective solution for you guys right now until we get a dedicated mobile solution. On the bright side, you do not get a neutered mobile experience.

    There was a time when 400 wheel horsepower seemed like a lot out of the stock frame N54 turbos. Then the 500 wheel horsepower mark was crossed. Then the 600 wheel horsepower mark. Now, we are on the verge of cracking 700 wheel horsepower with modified stock frame N54 turbochargers. Who ever thought this would be possible? It truly is impressive and truly a milestone in N54 tuning. Really, it's stunning considering how many times in the past people would complain about the 'tiny' snails on the N54. Well, those tiny snails are making some big power with the right modifications. BimmerBoost would like to congratulate member @The Ghost for his achievement. His data and details are below. Continuing from my previous thread, I decided to go back to the dyno to do a few tweaks. My setup is as follows: N54, FBO, 6MT JB4 G5, Custom back-end flash VTT 2+ turbos (20T, clipped) VTT turbo inlets, w/BMS DCI BMS Port Injection kit Split Second injector controller (AIC1-G4H) Fuel-it Stage 3 dual LPFPs e85 Stock exhaust (catted) The only change since last time is I ditched my customer rear inlet, replacing it with the VTT silicone hose. This fits much better and is actually shorter than the one I build by a good bit. I didn't have long on the dyno, so I upped the boost slights (holding 27.x) and added some mid range timing (10 degrees max now). I was very pleased with the results. Here are a few notes: I still have a tip-in rich condition, which I will fix in the PI map Boost is not hitting target (28psi) - I may change the JB4 rpm-based duty bias to see if it will hold 28psi (there seems to be more pwm headway, albeit small) The car kept making power with timing - I think I could run 2 more degrees as VTT did, perhaps cracking 700whp - I decided not to risk popping the motor today :) I'm still waiting to remove the catted exhaust in favor of a 3.5" single Attached are some dyno comparisons: Comparison between my previous personal best and my runs today My maxed FBO meth/e85 car vs. my final tune today FBO map 0 baseline vs. today's final tune Here is the datalog of the last run: http://datazap.me/u/ghost/dyno-log-3-105?log=0&data=1-3-4-11-18-24-25-26-27-28-29&zoom=30-81 Special thanks to Terry@BMS for the extensive support and parts, Fuel-it, and VTT for badass products and killer support.

    My guess is the tech saw the needle reached yellow bar, even not red yet, he let it go. I'll ask them to keep it to 7500 next time, b4 tuning.

    What have you upped the WG spring to? I remember you saying a 10lb would be the best. (lower the better since jb4 controls 4x the WG spring). I was going to switch my 14lb spring to a 10lb. Should i just leave the 14lb in?

    I specifically asked the NHRA about Bahrain. I am told it is a member of the World Wide program. I don't think this means it is certified though. I'm not sure I'm trying to get clarification but I would think your source is accurate.

    Ash's car touches 26 psi for a very small amount of time, its basically a 25-23 psi curve, Cal is targeting 27-28 psi the whole run, its going to make a huge difference which you can see. Either way the turbos are capable of this power with the right set up. Obviously a 6MT is going to have an easier time making power. Look at bright side, over on E90 we have people comparing 900HP turbos to these, and saying LOOK THEY MAKE MORE POWER!!!!! :facepalm

    We're testing different cars, on different days, across the country, so I'm sure the correction values are appropriate for each vehicle. It's just another variables introduced. Our E92 seemed a bit more palatable compared to your latest VT2 results uncorrected, for whatever reason. :) But that tiny filter on the 6266 is an issue we need to address somehow at some point.

    All good points. I am of the same mind: run what you brung. That is, the psi doesn't matter as much as how much you can get out of it. I also compared those charts with various correction factors (and with no correction), and the deltas between cars are about the same.

    It was hitting that peak but then auto tapering down to 29psi at redline. The packaging of the FFTEC makes it almost impossible to get a decent size air filter on the turbo. Our larger filters won't fit. But we've upped the WG spring and will reevaluate power shortly. Hoping the turbo can hold 33psi to redline and come in around 750whp. If not then we'll probably change that setup around. I'm not too concerned with who makes what at what boost level. Others may be. But I mainly want to see what each configuration is capable of maxed out. Ash's VT2 which we tested here did "only" 600whp @ 26psi. But we didn't try to max it out. It's also an automatic. I've also noticed correction factors play a role with a lot of the higher numbers in each configuration. Here is a comparison "uncorrected".

    Note attached (it is AT vs. MT, hence AT stopping earlier). Terry posted the overlay of the 6266 G2 and the VM6466 on the prior pages which are both ahead once spooled. I know! Looking at all of these graphs, it is clear your manifold really is the best ST TM manifold out (IMO). Spool on the G2 6466 is crazy in general, AND it can support big power.

    Yeah not quite big enough, I already placed the order for the new one. It is a slightly larger core then the VRSF and overall as well, Hoping it will turnout. Realistically it's more surface and volume so should work the same if not better. Where do your IAT's' sit before and after runs typically? I expected to outflow the IC and exhaust but was curious how far the factory exhaust and my little IC would take it. Wasn't expecting to have everything just work without miss or any other issues TBH so figured it would be a while before I was out flowing em. I really should say it's a good thing haha.

    Id go with the VRSF 7" IC. Payam, MR2Josh, myself (on 2 ST cars) use it with no issues. IAT stays well within reason. Your Godspeed 5" just isnt cutting it lol
