Anyone building a SINGLE TURBO S55 yet??

PTF. Can your BM3 be used to overcome the inherent tuning challenges going to a single turbo setup bring? Any insight on your software and more importantly, tuning experience on this, would be highly appreciated.. thanks.

We've been contacted by some vendors about working with them on this exactly. We've done it before with a Cobb AP on the N54 where we were limited in only the tables provided by a third party. With bootmod3 we're in full control which makes things easier to do when we need to dig up or create anything we might need to go forward.

In a nutshell, don't see this being a huge deal to do. On the hardware side the S55's single turbo exhaust manifold would be very similar to how the N54 single turbo manifolds are done with O2s placed pre-turbo for fuel control. You'd run the external wastegate with an external boost controller. On the software side we'd need to turn off a couple of codes and go from there.

Let's make 2017 the year of the S55 single turbos out there

THAT's what I'm talking about!! Thanks for your input PTF, very much appreciated and what I myself suspected all along.

The tuning should be very straightforward for this and the hardware itself has essentially already been made with the N54's motive900 package. These S55's would be absolute monsters on the highway with this** Hope someone offers this soon!

Well...it won't really be a walk in the park as there are unknowns as with anything being done for the first time, but, not rocket science or brain surgery either

"It's not exactly rocket science is it..." And definitely not "brain surgery!" Lmaooo !

Exactly the point I've been trying to make in this thread.

If you want to do the software side testing I already have a complete single turbo kit ready to go.

My fear is that not being able to flash the transmission will hinder from properly using the capability of the single turbo setup. Also it will kill the performance of the car from a stand still , as there is not way to get the rpms high enough to launch it in the powerband.

Dont you guys have a 6-spd MT car as well where none of this would be an issue on?

ps: I love the fact you guys already had single turbo hardware lurking up your sleeves!!

We sold the manual trans car a few months back, we still have the DCT car however.

[BMW M4 PWR]

Awe man.. gotcha* Lookin forward to YOU guys maybe being the first in the WORLD to run a single turbo setup on an S55 powered M4

Finally, I'm intimately familiar with the JB4. I've been playing with turbo 6 cylinder BMWs since my first 335 (I've had 3) in 07. I was the first person with a juicebox other than Terry himself back in the day and helped a lot with it's development. Technically, the JB4 is not doing any kind of boost control at all on the S55 unless the EWG plugs are installed. It's simply biasing the MAP sensor data and relying on the ECU to do all of the work. This is in contrast with the the N54 JB4 in ISO mode for instance, which directly drives the WG solenoids itself, while routing the ECU signal voltages into resistors on the board to keep it happy while being completely out of the loop on actual boost control.

Very interesting, sounds like a better design for the S55 JB4 than N54... Does this obviates the possible incompatibility issues with the piggyback not communicating with the TCU?

Again, why the heck don't we have a "Motiv900" based single turbo set-up on a single S55 powered car yet!?!? This is an easy and YUUGE opportunity for a vendor (or even owner) to be a "worlds first", and break all the current records on this platform...

[BMW M4 PWR]

Have you seen the Movit900 single turbo setup's on the N54 motors? Our single turbo setup would be pretty much identical to that! Even though it's tight it's greatly worth the benefit in that you can hold the torque curve to redline* And shift everything to the right on the dyno/power curve. (Making it actually MUCH better for traction) This has already been done before on essentially the same powertrain and chassis bro (dimensionally*). The only reason it's not being done yet are the inherent "first timer teething issue" costs and the fact that people who'd want an easy 800+WHP with no factory warranty aren't enough to mitigate the cost of doing it at THIS point in the platforms life cycle. They're going to wait until these cars are old pieces of sh*t (with its successor already out) when "all of a sudden" a half a dozen 1000HP options become available... (same thing happened with the S54's which had WAY more challenges to tune than these new motors do) We already have the tuning & fuel solutions for it for gods sake

Having said that^^ I'd like to see how a new "twin" setup would be easier or allow better spacing than a single for big power. Sincerely I'd like to something on this by someone*

[BMW M4 PWR]

I don't see a twin manifold/ twin turbo design (that can support over 800whp) being realistic or easier/or cheaper than a single manifold single turbo design on an *inline 6*. As has been the case with EVERY powerful inline 6 turbo motor in history! (Including the N54's and N55's which the S55 was modeled after) But sure, show me a direct fit twin turbo design that can achieve 800+whp easier & cheaper than a traditional single (a pipe dream) then I'm ALL for it brotha!

Keep an eye out for a dyno sheet of my car within the next 2-4 weeks. Yuge things in the work, its gonna be fantastic.

Believe me, I would LOVE to! Make me a believer brotha

...ps: I highly admire your taste in your build lol

Somebody buy it and let us know how it goes. It looks reeeeeally easy to put together.... You would "only" need a few other things

[BMW M4 PWR]

Wholly moly!? What the heck!

[Vectors2final]

Must have been a nightmare if they're backing out like that, no?

[TPG Tuning]

Nightmare? No

Simply moving on from this platform and no longer need the kit. We had issues with prior turbo companies that led us to focus more on a single turbo market. However we were then fortunate enough to build a great relationship with Pure Turbos and have since focused on utilizing their turbos on our car for testing and data. Our lease will be up in October to which we will buy it out then offer it up for sale as we are looking to expand into a new platform.

This is a great kit with huge potential for the right person. To my knowledge there is no other single turbo kit for sale for this car. With the right person behind the keyboard this could be a fantastic addition to your M3/M4. The kit already has drawn attention world wide and surely will make any owner happy. Regretfully we will not be continuing any R&D within the S55 platform.

No one said it would be " really easy " to do. A skilled shop should be the only one handling this project. As stated you will need some minor fabrication to make or adapt your catback to this exhaust. Aside from that you will need someone capable of tuning the car. BM3 already said they would be capable , it would merely take time.

If there is any other confusion let me know.

I know somebody on here said it would be easy. Don't remember who. I was just poking fun at anyone who thinks it's so easy to build one is all.

Piece of cake!!

[BMW M4 PWR]

Any headway on development on a kit by anybody in the last 2 months? I see 2017 as being the year we see our FIRST aftermarket Single turbo kit (or twin kit with its own custom exhaust manifolds*) I emphasize the last comment as the stock exhaust manifolds (which in turn limit the size of turbine that can be run) begin to choke the CFM's up top under high boost/high rpms when ~700+whp... this is why you see the torque fall dramatically on any high boost dyno power curve. Without addressing the manifolds they become the limiting factor asto the power ceiling these cars will ever make...
