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.

Cheers,

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.

[ATTN]

I read this thread and also his first thread he posted before this one, its pretty impressive.

Thats about.... 540 Australian?

[miro67]

450kw!

Huge progress for the N54 platform which an upgrade that not only makes buckets of power, but makes your upgraded hybrids more efficient and go stronger for longer.

Will be interesting to see what this means for stock turbos and the gains that are available there!

Hmmm, sounds about right as 540rwhp equates to around 400rwkW. But I would prefer to think of the delta achievable with these in combination with RB's over maxed out stock turbos.

Once again I would be focusing on the delta, as dyno figures can be vary substantially for a number of reasons.

I am very confident that a N54 on stock turbos making around 300rwkW would comfortably see 400rwkW+ with the addition of RB's and the TFT intake/turbo inlet system.

Those making around 355-360rwkW on RB's now should crack the 400rwkW mark without a lot of fuss. I know there is talk of substantially higher gains to be had, but I would rather errr on the conservative side until we have seen the results from a local guy with known power figures on a particular dyno. I would love to see 425rwkW+ out of this combination but I suspect the turbos will have to be spun pretty hard to achieve those figures and 400 at the wheels is already a fuck ton of power, haha.

Cheers,

JD.

TFT inlets are LHD only tho, correct?? Thank you steering rack...

There are a few sets getting shipped to Australia

Love it how people keep it on the down low

Shhh!!!

Will let you know how it goes brother Jackson

And no doubt JD would be 'involved' in those few sets I dare say!!

Not a bad guess.

So Peter@Advan, JD75 and I will be piloting the first set in collaboration with Advan (obviously) to test fitment with RHD compatibility.

We'll need to assess if any changes or modifications are required here.. But it will certainly be interesting, but with Advan's experience - no ot

Brian is reasonably confident that his kit should be RHD compatible. Rob Beck is even more confident, as he is quite familiar with our RHD rear turbo orientation and compressor discharge pipe design. If Brian had built the turbo inlet pipes around an optimised comp discharge pipe, we would probably be f'd!

But worse case scenario I have a trick or two up me sleeve to ensure compatibility.

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.

A nice pic of all the various components included within the kit.

[CashedUpBogan]

What's the price of one of these kits landed and any major gains on stock turbos? I'm willing to be guinea pig for stock turbo testing hahah

Hey mate,

I'll send you a PM regarding pricing.

As for gains on stock turbos, the jury is still out on that. But if you are FBO with Meth' and or E85 whilst running an aggressive tune that sees a boost target of 18psi at 6,000rpm, I'd be very surprised if there are not some decent gains to be had.

I would also suggest you modify the OEM compressor discharge pipe too, as dyno testing done by Peter@Advan saw a pre/post modification gain of around 20rwkW at peak power with on 16psi of boost. I should note that this was on a car with RB turbos so the RB's would be moving a lot more air at 16psi than the stockers, but if you chasing power by removing the turbo inlet restriction it makes perfect sense to fix the flaw with the OEM compressor discharge pipe whilst you are in there playing around, so to speak.

Cheers,

JD.

How many hrs of labour do you guesstimate to install the kit?

I'm guessing it would be 4-6 hrs for a workshop?

[bradsm87]

I'd be very, very interested in buying just the intake pipes and making my own coolant tank solution. From what I can see, roughly (My personal guess. Nobody take this the wrong way) 3/4 of the cost of the kit is for the coolant tank relocation (BMW coolant tank, lower and upper charge pipes, hoses, clamps etc.).

The BMW coolant tanks are only huge to accommodate for people who don't check the coolant level often enough or don't pick up on small leaks quickly. I think that a generic aluminium cylinder with half the capacity of the OEM tank would work fine and fit near the power steering tank without the requirement for charge pipe modification and bring the total cost way down.
