7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Finally a supercharger in the works for the e65/66, 745 and 750...

FINALLY... who is gonna be the first?

and its roots type so thats the best style supercharger, i think...

gonna be released at the end of the year.

"The upcoming ESS N62 TVS Series supercharger system features the Eaton TVS 1900 rotating assembly in a ESS proprietary inlet driven SC housing mated to a high-flow CAD designed cast aluminum intake manifold system. TVS Stage 2 features a massive manifold mounted liquid heat exchanger with dedicated high capacity cooling circuit. This highly efficient, positive displacement Eaton TVS based design generates massive torque over the whole RPM range. The ESS N62 TVS system is virtually inaudible, and completely maintenance free.

This system will be available for the following models :

E60 545i
E60 550i
E63 645Ci
E63 650i
E65 745i
E65 750i
E53 X5 4.4i N62
E53 X5 4.8is
E70 X5 4.8i

Estimated power output :

x45 N62B44 TVS1 : 440HP
x45 N62B44 TVS2 : 475HP
x50 N62B48 TVS1 : 460HP
x50 N62B48 TVS2 : 500HP

Estimated release : Q4 2010"

i am sure it will cost you no less than 6 to 8 grand then a few more grand to tune it. oh yea and dont forget the great transmition the bmw comes with lol. it will cost you more than its worth to put it and thats not including all the things that will go wrong and need repair. i say trade your car in and buy an alpina less headache and alot more rewarding.

And don't forget another grand for a new hood. There's no way that roots blower will fit with the stock hood.

ESS

they make great kits... very reliable

i guarantee they already have some cars in the works because they test their superchargers for months before release.

i wouldnt mind being a test dummy also

i can only imagine the error popups you'll get with a aftermarket setup on a 7...

B7 it is.

I was wondering when someone would do this. VF has one in development but, it's been in development for like 4 years already.

Why would you think a turbo would be easier or cheaper? You are talking two expensive turbos, new exhaust manifolds, intercooler and associated piping, etc... I don't see how it's any cheaper and it's probably harder to package.

At least with the B7 being around they know a supercharger can be packaged into the engine bay.

I bet it will fit just fine with the stock hood too since it's replacing the rather large OEM variable intake manifold. I'm really looking forward to seeing one of these put together.

Thats nice to know but i'd rather buy a B7.
Even tho i wouldnt mind to have an intercooler showing under my euro tags, think that would look nice and the sound of the supercharger would be sick

Any word on whether a transmission swap (e.g. to a 6HP32Z or something) would be necessary? (assuming so)

1.ok first turbo is cheaper to tune. you get more hp's dont forget a supercharger uses about 5- 10% of all the hp it makes just to turn itself. a turbo is free power.

2.the whole changing the manifold thing is old. all you do is replace your muffelr with the turbo in the back and run pipes to the front. alot of turbo companies are doing that.

3. the problem with this system is you have to remove the whole top of the engine to install it thats alot of money . plus they have to match the tuning from bmw to make the intake work properly. also positioning of sensors is very inmportant.

4. its one thing if your craming more air using a turbo and all you have to do is replace the fuel injectors and spark plugs. but this is surgary. remember its not a chevy v8 your souping up. one wrong move and your engine is done.

look at the x6m its turbo not supercharged.

It's pretty obvious you are talking about something you have no real technical knowledge of so please just stop.

Yes, a supercharger does have some parasitic loss to drive it that is a disadvantage. The advantage it has over a turbo is that it makes smooth linear power across operating range.

It's absolute BS that the tuning is easier for a turbo. Since the turbo is not directly linked to engine speed your boost pressure can be all over the place and fluctuate with things like weather, engine load, throttle position, etc...A supercharger is less effected by these things.

When going from NA to FI tuning the ECU is going to be a decent amount of work whether you use a supercharger or turbo.

So, you'll criticize the parasitic draw of a S/C and then you'll stick one of these horribly inefficient muffler mount turbo systems on?

You want the turbo as close to the head as possible for good response and to get the exhaust gasses at their maximum volume (hottest). If you are building a turbo system a muffler mount is your last resort. Never mind the complications of packaging the piping heading back to the engine bay away from heat sources with the 7's nice flat bottom.

No, you'll most likely just be removing the intake manifold and some of the belt drive. The cylinder heads stay put and so would the timing chain.

You are removing the OEM intake manifold and replacing it with the S/C assembly basically. If they are tuning the ECU to work with forced induction they can reset any parameters they want/need to work with their setup.

You'd have the same issue with any FI setup whether it is turbo or S/C

That is the lamest analogy ever. The same goes for any engine. If you **** it up you could easily destroy any engine.

I like your oversimplification of a turbo setup here. If you are replacing the injectors you are probably 75% of the way to having the intake manifold off. With either setup you are most likely going to need to address the increased fuel demands of adding 100+ hp.

Yes, the X5/6M are turbo charged but, it's not some half ass muffler mounted setup like you are talking about. It's actually a really incredible engine if you know what you are looking at. The flow of air through the engine is pretty much reversed from every other V engine in the world and it honestly makes more sense if you think about it.

http://www.ausmotive.com/images/BMW-X5M-engine-07.jpg

Look at how they put the turbos into the valley of the engine to minimize the distance from the head to the turbo for maximum efficiency and the width of the engine package.

It puts the exhaust (and it's heat) over top of the engine and away from the fuel and oiling systems.

While it's not listed I don't see why the E66 wouldn't be able to use the kit. However, at this rate there probably won't be any E65 or E66's on the road by the time this kit comes to market.

Your bike looks like it's an R1 from the pic. You can't quite get to 200 mph either unless your speedo is broken
