BMW's 4.4L twin-twin-scroll turbo v8 engine
 

I guess it goes in the X6, a funny looking SUV thing:

Not really ideal flow-wise for the turbo on the right (fed by yellow/blue) but sure fits together nice:

So the 3.0L twin turbo can make 330whp on dyno dynamics pretty easily, wonder what this v8 will be capable of...installed in an M3 :)

Crazy Germans lol, that's pretty awesome though, m3 def needs this.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Dang thats nutty. Hope they dont have any heat issues having the turbos sit on top like that. Pretty squished setup!

One giant turbo would be sweeet. haha

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

I doubt if it would fit in the M3 due to height, but would be a great option for the M5, which has the so-so sounding V10. Although with aftermarket exhaust, they sound like an Indy car.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

that looks pretty crazy. would be quite insane if it was in the M3 or the I series.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Wow? Kind of a clusterfuck under the hood, but still pretty sweet.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Call me crazy but I just don't like rwd cars. Sounds like a X with bolt-ons, corn & tune will match as far as you can take the six-cylinder version. I had almost forgotten about that thread.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

The X is awd...

And RWD is awesome fun.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

It'll be sweet. Having worked as a BMW service manager I can tell you, it'll work as advertised. BMW holds nothing back when it comes to the way their cars drive and perform.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

That looks ridiculous to me.. All I see is a shit ton of heat build up. Plus it looks like a little plastic fitting, or whatever you wanna call it a couple inches to the left. Sure it may work but I see alot of problems that will come into play with higher mileage.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

I see heat shields everywhere, remember the pic above is a cut-away. This setup sure makes oil feed and drain lines nice, think about doing a bolt-on turbo upgrade on this thing...woot! :)

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

New v8 diesel pickups will (or do now) have a reverse-flow head design like this, puts the heat all in one spot, and it's MUCH more compact this way. Think of having a turbo hanging off the sides of a wee-8, and how much less room you'd have for wide tires in the front. ;) It's also for emissions, cost savings (single down pipe and exhaust as opposed to two that merge under the car.

I like it. Direct injection, all aluminum engine.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Well, it's hard not to like a BMW. They pretty much do everything right as far as a stock, daily driver goes. I'd certainly consider picking up another 325xi as a daily, but that's pretty much the only affordable version and it's 175hp or something piddly like that.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Too bad its direct injection, good luck making much power with that, ask the Mazdaspeed guys.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Direct injection is in my car and various others that can make good power. You just need a high pressure pump and you are set.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Yeah, I guess the CDFP (cam driven fuel pump)is more of a problem than direct injection is. As long as someone actually makes an aftermarket pump that performs well I guess.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

^yup, almost ALL of the aftermaket pumps for the vw 2.0t (direct injection) motor have issues with wearing out cam followers or way worse the actual cam lobe itself! Stupid. There has to be a better way.

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

So why doesn't your car make good power? ;)

Re: BMW's 4.4L twin-twin-scroll turbo v8 engine
 

Hahaha because it has the stock turbo. :)
