RyM3rC Posted March 2, 2012 Report Share Posted March 2, 2012 interesting. I was half-expecting a sequential setup, or are they just doing 2 cylinders per turbo? Piping errywhere! Stupid germans, making awesome engines then only giving us failomatics to shift with. Quote Link to comment Share on other sites More sharing options...
Rally Pat Posted March 2, 2012 Report Share Posted March 2, 2012 Yo dawg, I heard you like boost, so we put a turbo in your turbo in your turbo, so you can boost while you boost while you boost. Quote Link to comment Share on other sites More sharing options...

stangsn95gt Posted March 2, 2012 Report Share Posted March 2, 2012 5500 red line, isn't that pretty high for a diesel. Quote Link to comment Share on other sites More sharing options...
RyM3rC Posted March 2, 2012 Report Share Posted March 2, 2012 In b4 triple-turbo failure, triple-turbo coolant/oil leakage, head shearing off due to 600 lbs of turbofold hanging off, and excess torque killing other parts Quote Link to comment Share on other sites More sharing options...
Draco-REX Posted March 2, 2012 Report Share Posted March 2, 2012 interesting. I was half-expecting a sequential setup, or are they just doing 2 cylinders per turbo? Piping errywhere! Stupid germans, making awesome engines then only giving us failomatics to shift with. It is sequential, it just has 3 stages. Small variable vane for low end spool -> a big one for midrange grunt -> a second variable vane to fill out the top end. Seems kind of overkill for driveability. 381hp/585tq isn't a crazy amount for a multi-turbo diesel unless it has a tiny displacement. But doesn't 550 mean it's roughly a 5L engine?

spankis Posted March 2, 2012 Report Share Posted March 2, 2012 I think the numbers in the model name stopped having any correlation to powertrain some time ago... Engine: Six-cylinder in-line diesel engine with M Performance TwinPower Turbo technology, aluminium crankcase, three turbochargers (high-pressure, with variable turbine geometry), common-rail direct injection with piezo injectors, maximum injection pressure: 2,200 bar. Displacement: 2,993 cc, output: 280 kW/381 hp at 4,000 – 4,400 rpm, max. torque: 740 Nm (546 lb-ft) at 2,000 – 3 000 rpm, specific output: 93.6 kW/127.3 hp per litre of displacement.

Nate1647545505 Posted March 2, 2012 Author Report Share Posted March 2, 2012 Notice turbos feeding turbos, this is technically a "qasi-register compound system" Keep in mind this is a diesel.... Quote Link to comment Share on other sites More sharing options...

RyM3rC Posted March 2, 2012 Report Share Posted March 2, 2012 Notice turbos feeding turbos, this is technically a "qasi-disaster compound system" Keep in mind this is a diesel.... Fixed that little typo for you there. Considering the issues BMW had with the bi-turbo 335/535/etc I'd be a little reluctant to own one of these until a couple model years pass.

Forrest Gump 9 Posted March 2, 2012 Report Share Posted March 2, 2012 Definitely not buying that!! Quote Link to comment Share on other sites More sharing options...
BigOxley Posted March 2, 2012 Report Share Posted March 2, 2012 i think the 550 refers to $550, as in, the minimum cost for a mechanic to even look at this engine. Yo dawg, I heard you like boost, so we put a turbo in your turbo in your turbo, so you can boost while you boost while you boost. :lolguy: Quote Link to comment Share on other sites More sharing options...

unfunnyryan Posted March 2, 2012 Report Share Posted March 2, 2012 Well when one of the turbos goes out thatll be fun as fuck to diagnose. Quote Link to comment Share on other sites More sharing options...
Draco-REX Posted March 2, 2012 Report Share Posted March 2, 2012 Ok, so 600tq from 3L is pretty good for a stock engine. But it's still a lot of complexity for just driveability. Quote Link to comment Share on other sites More sharing options...

Nate1647545505 Posted March 2, 2012 Author Report Share Posted March 2, 2012 I see it as brilliant engineering, which is often incredibly complex theories made viable and simple. I'm sure vairable cam timing, lift, electronic throttle control, etc etc were all thought of as a blanket of complexity for a simply task, but yet they've revolutionized the industry. Hell....one turbo is complex enough, add VTG and three of them....good lord...amazing. Quote Link to comment Share on other sites More sharing options...

JaSSon Posted March 3, 2012 Report Share Posted March 3, 2012 Look at the pictures in the 5post thread. It uses a small turbo to directly feed into the large turbo. Bizarre. Quote Link to comment Share on other sites More sharing options...
