607AWHP/618AWTQ: TFT Inlets + RB Turbos + BQ/Wedge Tuning

Hey guys,

I find it hard to believe some of the forum regulars have not read this thread started by the owner of a RB powered N54 335xi in the States...

But just in case here is the URL and yeah I'm just as gob smacked as everyone else about the results, including Rob Beck for that matter.

http://www.e90post.com/forums/showthread.php?t=1083247

Cheers,

JD.

P.S. I wanted to do this and had the ability to do so a few years back when I first installed RB's on my car, but the general consensus was that whilst there would be horsepower gains to be had, they would NOT be super significant. But God damn I should kick my own arse, haha.

This is huge progress for the n54 platform, can't wait to have them installed.

They are also testing the gains of these in stock turbos also.

Couple N55 upgraded inlet pipes floating about too. I believe pure made one and has it for sale now.

Yep, this is going to transform what kind of power levels can be achieved on RB turbos. Where as the power delta between OEM and RB's has previously been around 50rwkW (better case scenario), the addition of the TFT intake/inlet system would see a delta of of at least 75rwkW whilst the turbochargers are likely to be running less boost leading to a long and leisurely life, haha. For those guys that want to tune for "kill mode" and dyno glory I suspect a delta of 100rwkW+ will be very much attainable.

To put this into perspective, any full bolt-on guys that have made close to or slightly above 300rwkW on the Advan dyno should be able to crack the magical 400rwkW figure should they choose to.

That is just friggin crazy power from a hybrid turbocharger that is capable of excellent spool characteristics, yeah a big single conversion should comfortably see 425+rwkW on the same dyno but that is a whole different kettle of fish...

Cheers,

JD.

As Ian alluded to this kit is apparently being tested on the OEM TD03 snails too. Common sense would suggest that the gains to be had on the stockers would be minimal as the airflow rate of the OEM turbos is quite a bit less than RB's.

BUT no one ever thought including Mr Rob Beck himself that such a massive bump in power would be realised with a properly engineered turbo inlet upgrade, if they did it wouldn't have taken so many years to come into fruition.

So it wouldn't surprise me if some decent gains were to be seen by the stock turbos guys that are running 18psi around 6,000rpm. I suspect at the very least the upgraded inlets would allow the stockers to hold better power to redline and decrease boost requirements to achieve the same power levels, which is great for turbocharger longevity.

I want to see the TFT inlets with the vargas hot side pipes. Talk about the best of both worlds...

Just when you thought N55 were closing the gap something simple like these inlets open it up again

I have a pure inlet pipe on the way, going to put it in along with a Vargas shotgun pump and a revised wastegate and try for 20+psi with 100% e85.

JD75 does this mean you're going to dust off your 135i and get her going again?

Yeah the VTT hot side charge pipe or compressor discharge pipe looks quite nice indeed. But unfortunately for us RHD guys the last I read Tony was saying this could take around 3 months to produce.

What type of work are we looking at to get these In?
Don't you have to drop the engine or take the head off to access the rear turbo?
I briefly read a thread..hopefully it's a simpler task.

At this stage we are yet to confirm if the kit is 100% RHD compatible, so I wouldn't like to hazard a guess on the labour required for the first installation.

But you certainly will not be removing the cylinder head to ensure fitment. Installing the rear turbo inlet pipe is going to be the major task and that's providing our RHD OEM compressor discharge pipe (aka hot side charge pipe) doesn't foul on the turbo inlet pipe(s).

Please refer to the below post for more details regarding RHD compatibility.

Cheers,

JD.

Hey guys, a cheeky copy & paste from the 3 Series forum.

Yeah ok, so now that Ian has let the cat out of the bag, I'm happy to say that I have 3 complete TFT intake/turbo inlet kits on the way from Brian of Trueform Technologies

Yes, Ian will be the guinea pig (lol) for test fitment of the first kit at Advan performance. But I'm reasonably confident it will bolt up and after speaking to Pete on Tuesday he's more than happy to massage the fitment should it be required.

If it's a case of Brian's inlet pipe(s) fouling badly on our OEM compressor discharge pipe aka hot side charge pipe, I know an excellent fabricator that Peter has used in the past that can sort that out for us.

RB guys should be running a modified discharge pipe anyway to remove the flow restriction on the rear turbo which results from excessive collision crush clearance. So if worse case scenario the OEM pipe had to be binned and a new pipe made from scratch, we would end up with a pipe with better flow properties that could also be made from the same 304 stainless steel for durability reasons, that Brian has fabricated the rest of the kit from.

But fingers crossed with Peter's expertise Advan will be able to install the kit without the need for additional fabrication costs.

Cheers,

JD.

Do we know what gains these will have on stock turbos? Also Pump gas gains with RBs?

Hmmm, logic would suggest that stock turbos would not benefit significantly from the improved intakes, for starters the OEM inlet snouts are properly sized for the TD03 compressor wheel exducer, where as on Stage 2 turbos such as those from RB or VTT they are not. The Stage 2 turbos also move a lot more air than the stockers.

Having said that no one would have thought the TFT kit would realise such substantial gains on RB's either, so...

I'm pretty sure some stock turbo guys in the US would have bought this kit so we should know the answer to that soon enough.

As for pump gas gains on RB's, yes I would have to think so as the improved compressor efficiency should allow for an increase in the power ceiling relative to a fixed octane, before the onset of knock etc.

I was reading during my less than busy day at work and I read a few threads where guys were saying that the inlet on stock turbos isn't really for a 'large' power gain.
It's more to do with giving them better flow so high boost can be kept on higher rpm rather than tapering it down as a lot of tunes do because there wasn't enough flow on the top end to keep them spinning fast enough.
It sounds plausible and if true is be happy with just that.

i think i will sit on the fence for now until someone does the R&D here in australia and fits this, without a doubt i think this kit will need work for our RHD cars.

I believe that Justin has that in hand with the first Australian customer. We will know how well TFT fits, albeit with modification or not.

Looking forard to the results.
