    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.

    Hello everyone, I decided that I am going to sell my beloved 190e. A lot of you know this car. I bought it from Mark (5dbl-o) on this forum in January of 2012. I flew out to Virginia, picked it up, drove it home, and have enjoyed it greatly ever since. Below is a portion of his original FS thread that I feel I should post since he is the one who performed the major mechanical changes on the vehicle. 1/10/2012: "What a beast. I have close to 10k invested. many pics (mb tech for over 20 years , I personally put this car together but now time for a boat) anybody seriously interested call me work # 434-386-9035 Bought on ebay from dealer in Toms River NJ for 2600.00 It has 80,000 miles on the car. Converted to 3.2 liter 5 speed manual. Also bought a 1995 e320 sedan for the donor car. I removed the engine and replaced the head gasket and performed a nice 3 ange valve job. Replaced the timing chain , water pump and other items I cant remember. Custom made the wiring harness everything soldered and heat shrink. Bought a getrag 5 speed from a scrapyard for 600.00 (it had been on the shelf there for 10 years. Yes I got very lucky. The fluid was so clear it was like brand new) it is flawless. Genuine new MB flywheel My buddy machinist (34 years expert) took 9 lbs off the flywheel and balanced it for me. Installed all new genuine MB clutch and linkages, and everything that goes with it. Shifter and pedals from ebay uk. new bushings in shifter and new genuine MB shift knob/boot. Gathered all 16v body parts painted them and installed the body kit. (320.00 worth of fasteners) This car runs very strong and seems to never stop pulling. I installed a 329 limited slip from a e320 4matic wagon/ cut, shortened and sleeved axles properly. Dont want to scare anybody off but I do have nitrous installed and have run 1 bottle through it. Wow, Nice. Since this car was automatic it has the kickdown switch under the acc. pedal. That is the activation button and I tucked the child lockout switch under the console so it is always on and the child lockout switch that you see in the console just arms the system. factory look I moved the battery to the trunk because the new control units take up the old battery space up front. I run a passport radar detector and use an optical isolater so when the detector goes off it mutes the stereo . Interior and body in great ,great shape Beilstin sport shocks, front suspension and front brakes from the 95 e320. I have been an auto tech for 34 years and strictly mercedes for 22 years now You dont have a clue how strong and reliable a car like this is unless you have driven one with this conversion. Want to know more call me 434-238-8378 or 434-386-9035 Sorry, The rear diff was from a 91 300te 4matic. It is 329 limited slip with the hydraulic 100 % lock option." The car now has 90,000 miles. Other than much preventative and regular maintenance. The only changes I performed were OEM euro headlights/turn signals/tail lights and AMG Hammer wheels. The car never skipped a beat, has always been an absolute joy to drive and look at. After having numerous 190's including another M104 swapped car, I am convinced that this is one of the most properly built 190's out there. Shortly after buying the car, I took it to a local dyno day at PSI Proformance, where the car put down a healthy 222whp/226wtq on a Dynojet (no nitrous). I've only used the nitrous on one evening shortly purchasing the car. It's definitely a very nice boost, but I never felt the need for it enough to refill the bottle. The car starts, runs, and drives with no issues. I purchased a SPEC Stage 2+ clutch shortly after buying the car, simply because. I felt that the clutch will eventually need to be replaced, but it doesn't. I will include the new clutch kit with the car. Sadly, I am currently very busy, and do not drive the car often. It is by far the favorite car I've ever owned, but it deserves more attention than I am able to give it. It needs to be driven and shown around. I do not need to sell the car, and will not sell it to someone who will not care for it properly. If your 16 year old son is looking for a first car, I will likely not let that car be my 190. As far as an asking price, I am asking $14,000. This is a car for someone who is willing to pay to have a properly built, no expense spared, and ultra reliable car.

    I wonder if any of the piggy-backs can take into account for upgraded IC, and or any DPF/EGR deletes? or are these a must ECU-FLASH in order to accomplish such? if a JBD and upgraded IC works, that may be a better and simpler way to go. Best bang for the buck. I see Puerto Rican 335d has done a lot, any Dyno results by now? Thanks :) Hmm, what else can be done to the E70 US spec'd diesel? I know the 335d has many more options. wonder why?

    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.
