    Cpt_Rum-bo started a thread Linear Throttle Issue in N54
    Background info: my car is 2010 6sp FBO 135i and I've been tuning it myself for the last year or so running on E30. My issue is this and I've tested it in gears 2-6 and they all do the same thing. As I steadily add throttle, boost proportionally increases as expected to ~3psi. As I keep adding more throttle it always suddenly jumps to around 11psi, after which it proportionally increases to max as a keep adding throttle. I've tried so many things to change this but nothing seems to work. This makes coming out of a turn at the track very tricky as I have to try and predict the surge. Attached are the tables I adjusted that I felt should help. Hopefully others with more experience can show me where the issue is.

    Fellow N54 enthusiasts, I do too many projects to divide them up into separate threads, for the sake of simplicity I decided to start a build log for my E61. A little background on my style: Aesthetics are important to me but not at the expense of function so I do my best to achieve both, if there is a conflict, function wins. "Clean" is always the goal. I love details; details, details, details. Now that I have a garage I do all of my own work, I really enjoy the challenge of solving problems and figuring things out so a late model BMW keeps me busy on this front. When the wagon is broken, I fix it, when it is running 100%, I look for something to modify or break, I am sure many of you can relate. I love to retrofit things and "make them work." I also love having a 550awhp wagon that can run with pretty much anything on the street, while carrying mountain bikes, a dog, and groceries. Function! Day 1 of the build (September 2013) up to (February 2016) can be seen in the first 30 pages of this thread: This thread will continue where that one leaves off. For those inclined, my Instagram handle is "hoburger" Evan Here is a couple introductory pictures of my wagon in current trim:

    Reached out to fastgti69 about a turbo install and everything was going as planned. Due to my car failing smog and unable to get it registered, I let him know that I wasn't going to be able to make it for the install and asked to buy his coolant tank relocation kit so I can get it installed locally on 5 February and for him to send me an invoice. On the 7th, I was told I'll get an invoice but the day came and went without a word. On the 8th, I reached out again letting him know I had an appointment on the 10th to get the kit install and want to proceed with the order. I received an apology on the 9th and he requested my address and sent over the invoice. Keep in mind I've been waiting for an invoice/trying to order for 4 days. I received the invoice and paid within an hour on the 9th so it could get sent out the same day. I live and Vegas and normally get packages from SoCal next day. Last messaged I received was the kit would be sent out shortly early yesterday afternoon. I've reached out a twice yesterday evening and night and haven't heard a word. Never got a tracking number also. I shot him a final message this morning before dropping off the car and still getting ignored :angry-banghead: I have no idea if the kit even shipped. Searched everywhere on the web and cannot find a good working number. Hopefully the kit shows up today, but seriously, I really expected better customer service rather if I was spending $80 or $1k+.

    I bought a STETT cold air intake for my N54 powered 335i. Between the time when I ordered it and when i got it, I bought another project car and decided to leave my 335i alone. I opened the box to inspect the contents but I never installed the intake. It will fit on any N54 powered car, which can be found in the 335i, 135i, and maybe the early 535i. I paid $417.00 for it and I'll sell it for $350.00. Will ship at the buyers expense, but would rather local pickup if possible. Sorry if this is in the wrong spot, I'm new to this forum.

    DavidV started a thread G11: All new Alpina B7 in 7 Series
    his, ladies and gentlemen, is what a 600bhp, 193mph, modified BMW 7-Series looks like. It is the brand new Alpina B7. Unveiled by BMW USA, this is the third generation of Alpina’s 7-Series, and comes with a lot of very intriguing, very impressive numbers. Alpina don’t forget, has a long, fine, 50-year history of taking BMW models and adding numbers. The first of which involves power. Underneath the B7 lies BMW’s 4.4-litre twin-turbocharged V8. Here, Alpina has installed two specially developed turbos positioned within the ‘V’ of the engine, featuring bigger inlets and outlets. The entire cooling system and airflow has been rejigged too, to “remove bottlenecks” (we never realised the standard 4.4-litre V8 had a ‘bottleneck’). There are larger volume coolers, bigger, wider hoses and an air-to-water intercooler, along with external water and transmission coolers. The engine itself has had a going over too: there are new pistons, spark plugs and a stainless steel Alpina sports exhaust. This reduces back pressure and weight, and comes with the necessary valves for additional noise. The result? 600bhp, and a whopping 590lb ft of torque available from 3,000rpm (494lb ft is ready at just 2,000rpm). This revised engine is hooked up to an eight-speed automatic gearbox which has been beefed up to deal with the additional torque, driving all four wheels (though in the UK, we’ll probably get a RWD version). It’ll do the headline 0-60mph sprint in just 3.6secs – nearly a second quicker than its B7 predecessor – and rock on to a top speed of 193mph. That’s only a preliminary figure, too. It’ll probably go faster still… There’s air suspension combined with active dampers and roll stabilisation, and adjustable ride height. Like, for example, when you reach speeds of above 140mph and it drops by 0.8in. Neat. Want more? There’s active steering, Michelin Pilot Super Sport tyres, huge forged alloys, and rear-wheel steering. Oh, and bigger brakes. You’ll spot the trademark Alpina flourishes: stuff like the new aero-honed front and rear ends, those classic Alpina wheels, lots of leather and ceramic inserts inside, blue and green paint finishes and a nice head-up display. The new B7 will be available in the States from September this year, and prices – along with UK-specific info – will be revealed in due course. Always fancied a sub M-Power Seven? Step right up… Source Top Gear UK Pics:

    That would be me. I have been able to hit around 23psi with out a problem on E87 alone on a fairly conservative tune. I havent pushed beyond that (well sort of 25psi has been my max). We all know that the 450 will out flow the the HPFP so i took it beyond to see what it'll do in terms of flow and it performs as expected. I didnt realize when i posted that, that most people think if you say you have a 64mm ST and PI your pushing 30psi+. I have seen a DIY homemade 450 install run 27 psi on stg 2+ with PI and the same content E85 i have access to which is probably a lot higher than most. So needless to say if you have hybrids and PI this pump should be able to handle it. If your going to be a hero and run hybrids past 26-27psi then you may want a twin set up. That said i cant wait to see what Chris brews up on the next generation of systems. I can tell you his out of the box thinking, knowledge, and experience will far exceed everyones expectations. The problem will be do i have enough boost not fuel.

    We all already know the new B58 3.0 liter turbo inline-6 is underrated and makes considerably more power and torque than the N55 3.0 liter turbo inline-6 it replaces. BMW rates the motor at 320 horsepower and 330 lb-ft of torque at the crank. The M Performance Power Kit raises output to a claimed 355 horsepower and 370 lb-ft of torque. Considering the car is already making more power and torque than that without the power kit as it dynos 331 rear wheel horsepower and 339 lb-ft of torque at the wheels we can only imagine what the actual output is with BMW's power bump. Let's assume gains of another 20 wheel horsepower and 20 lb-ft of torque at the wheels. To find out for sure we will need to see a dyno but there is no denying the car moves very well in the video below. Keep in mind this is an xDrive model which is heavier due to the all wheel drive system. That just makes the 0-200 kph acceleration all the more impressive:

    It's interesting to see how some folks care a bunch about boundary vs. field corners when scouting, others don't really care at all. I'm more or less in the latter camp, though I don't think it's something to ignore all together. The two positions can require pretty distinct skillsets if you are trying to make a career playing one side or the other. Thought came to mind when watching the Clemson corner group...They never flip sides.
