To wrap it up, the small changes made to vanos timing, rpm limits, electronic accelerator pedal sensitivity, air-fuel mixture, etc. Previously I owned a 540i6 and I just assumed bumping up 70hp and 35lbs of torque on a 550 would have been night and day difference. It's right over the Woodrow Wilson bridge. The S1 suspension is just sick! I've been looking online to get some ideas for modifying this vehicle, but I just can't seem to find any custom E60s in this color. My mod list should, at speed, put out right around 30-32hp and 24-25 tq. Then I do agree that above 4k or so to the newly raised limit, it screams a bit louder not that the 550i Sport with the performance exhaust was particularly quiet in that range to begin with. I had a question about the Dinan intake; are oiled filters a requirement? Getting into a complicated older German car can sometimes be daunting, but the 550i does a nice job of balancing performance and luxury without the bills associated with the S85 V10.
That all being said, I wanted to make it my own if you were. It was going to be my car. It is a beautiful color. I have not yet dyno'd the car, no. I find myself driving without any music on just to listen to the exhaust, it's so fun! The software safely raises the rev-limiter by 250 rpm, enabling you to carry more road speed in each gear as well as optimize shift points for maximum acceleration. I went my route because I felt it offered a more well-rounded gain and some more practicality. And a costly mistake for me.
See my list of mods in my signature to get an idea. Matching Stage 2 Engine Software is highly recommended for optimum performance and drivability. Air from the added inlet is channeled through a carbon fiber duct, offering a tasteful high performance look under the hood. The tranny in the car I have read about in many online sources is estimated to handle upwards of 500hp and we're nowhere near that. That it comes to market at 50% of the going rate of Ms is an extra bonus.
Again, I am not a believer that a well maintained filter can hurt the motor, but to each his own. Either use sport mode , reset the car, or get a tune. Thats the thing about all my hardware mods, they're all most noticeable and beneficial at 3-4k+ rpm the performance software is noticeable the entire band. So when price negotiation began it was showing 4995. The larger bore further improves air-flow for increased power output and more immediate throttle response. I also have three sets of keys. Dinan High Flow Throttle Body 3.
I'm not certain at this point if I will ever mod mine because I'm not sure how long I will be keeping it but if I decide to pull the trigger, I'll be going with Dinan for sure. Which dealership did u use? It should definitely give me the sound I'm looking for, plus a little extra! Nerd, literally not at all. In comparison, peak twist on the N62 came at a much more realistic 3,400 r. Some people have had issues, many have not but it is definitely possible. I am not sure if someone has done this; until I have a little over a grand burning a whole in my wallet, I will do it myself and see if there are truly any negative effects. I'm seriously considering making the same mods you have done, but with an exhaust to match.
If you get 400 then thats great! It literally feels like a different car and is hugely fast. I was either thinking about doing what you did first or going with some supersprint headers. It was expensive, too, and though the M5 came with a massive screaming V10, the rest of the run seemed to be pretty tame. Hey man I have a 2008 550i sport. I decided to go the Dinan route because of their near factory look and warranty.

The exhaust gives you a just the right hint of sound, on the highway; you don't even know it's there. Matching Stage 3 Engine Software is recommended for optimum performance and drivability. It is truly a joy drive this vehicle. The thing that e60 550i's are often criticized slightly for is that unless you unlock the beast with a heavy right foot, at which point there's certainly a beast to be unlocked don't get me wrong, that they can sometimes feel a bit sluggish or laggard. Independent shop EuroConnection from 50K to 118K has balance of maintenance records.
I'm cool with that for very little money. Who knows, maybe 2-3hp at 80+mph? It should definitely give me the sound I'm looking for, plus a little extra! And who knows, maybe even very slightly better gas mileage? The throttle body in conjunction with the intake it harmonious, its likely not developing much extra power from the bottom of the rpm range but man do you feel them work in concert by about 3k rpms and all the way up. Thats a whole other conversation as to whether or not that causes any issues with the motor. We'll see I must say it's a pleasure to drive! For your entire list of mods head to Trinity Autosport in Tustin. If anything it feels slower between 40-70mph, go figure. Thanks for posting the info! I have a 550 sport and it just doesn't feel like the beast it should be. I've also been thinking about modifying to dual Quad exhaust 4.
