Steed Speed to Start making N54 Twin Scroll CNC Manifolds.

[Payam@BMS]

Proper short runner manifolds like these smash the excessively long tubed headers, as evidenced by Motive's spool and peak power. There's is with an open scroll T3 v-band too! Twinscroll T4 will be even better.

Not true at all. Our testing with the 6465 on our top mount kit, proved to be just as potent as their Motiv750 kit. Spool exactly the same, and power is the same.

[jyamona]

Just stop with that logic, and common sense... My favorite is watching people piece together a kit claiming they will do it for X dollars, you notice none of those people post total build cost when all is said, and done, not to mention time spent, because 95% of them look back and say I should have just bought a kit.

Who cares what they claim? It's not your money. A smart business man would just stfu about it and try and sell them your HPFP kit since they will definitely need more fueling.

[Ingeniator]

A lot of his manifolds already have the provisions for an o2 sensor per bank, he knows what he is doing. Many turbo diesel engines are DI also, and operate similarly to ours w/ fueling. But, yea cheaper cost of entry to ST parts will lead to some hilarious failures I'm sure from the ill-equipped I look forward to their stories haha

Thought I was quoting @fastgti69

You can't compare spool and power between two manifolds unless the turbo and car setup is the same.

[Ingeniator]

So as someone building a staged sequential. I would just like to say it will be more then one revision on this if they want to make any power on the N54. There is a reason motiv went through a ton of revisions. As for diesel and gas DI being similar you really don't know how a diesel works do you.

I do. It was a generalization as to the o2 / DI / fueling per bank conundrum.

Then you have proved your point yourself. If theyre not comparable now then you cant say it spools better.

Bahahaha

[Tony@VargasTurboTech]

Just got an email from Leen with that they plan on setting MSRP at. It is where I thought it would be, I will wait for them to announce it.

Unless they make a new manifold for the 6.7 ford/cummins they don't make a manifold for a closed loop diesel.

[jyamona]

I'm guessing $1200 MSRP, w/ an ~ $1000 initial group buy

[islandroad83]

But tony just think of the opportunity. All the N54's on the road. He was chomping at the bit to make this that is why a raffle winner got the ball rolling. I think he will make 10 break even and jack the price or discontinue.

Yes it did take somebody to get the ball rolling, nothing wrong with that. I am not sure why people are careing about breaking even or his margins. If its a quality product and does what it says tested and proven (that is will be) why not just wait and see.

There have been a few people actually, it different when you know how to weld. That's just it, the people that want to DIY don't mind putting in the time at all that's part of the cost savings. The main difference here is a tested and proven manifold for a decent price that was not prior throw into the mix.

One of the main reasons I am sure was it’s the first time they have attempted to make a manifold like Steed Speeds, they saw his designs and obviously wanted to replicate something like it. This can clearly be seen by their current turbo kit. The difference here is a company that has already been proven to make manifolds on turbo cars, not just diesel. I am sure there might be a few revisions to get things perfect that’s to be expected.

They are actually going to be ready to cut tomorrow to get the prototype over to CES. When have you seen any vendor work that fast starting to produce results?

Just got an email from Leen with that they plan on setting MSRP at. It is where I thought it would be, I will wait for them to announce it.

Just Spoke with Lean, $900 was a number that was flying around nothing was set in stone and still is not, he said he would be astonished if this even goes over $1100.

Tony the thing here is the majority of people are not trying to make a kit for 2k but if we can do it for half the total cost of other single turbos even 4k that's still a great price considering just your Stg2 are around 3200 or whatever.

Is the placement of O2 sensors going to be tricky, I am sure but its not like we are dealing with company that has not done this before and are more then motivated to see this though to the end.

Also i doubt Leen is going to jump on the forums, he is aware of the threads but obvi they become a mess from other vendors saying nayy, impossible, cant be done for that price and quality blah ect.. Why no just sit back and watch it evolve and see what comes of it. If it does fall on its face then you can throw out "I told u so" although i know sitting back is not your style.

[jyamona]

getting things cut starting tomorrow? damn, that's fast

I haven't seen one divided bank manifold from steed speed. All well and good to have faith but it isn't as easy as you think. There is a reason I went with the motiv manifold instead of building my own.

All of their twinscroll manifolds are divided, obviously. I saw a few pics of a twinscroll t4 they are making for an e36 also, with a single wastegate. I'm assuming this will be very similar. So, with the single wastegate flange, the banks are divided up to the turbo flange and the wastegate flange, so you have bank separation. Just place an o2 bung per side, similar to the ShaudFab design:

Yeah pretty sure those o2's aren't going to like the heat from the wastegate. As for a twinscroll mani being the same as a divided bank it is but o2 placement is everything. Considering they don't even have a test car in house your looking at a long lead time or a crappy manifold.

That was ShaudFab's design, and I agree, poor placement. No clue where the SteedSpeed one will place the o2's in relation to the wastegate. Word is they are sending it to CES (same company testing their e36 mani) for fitment and testing. Personally, my car is stored over winter anyway so I don't mind a few months wait time if need be.

Motiv has a awesome kit out, there is no doubt about that. I love products and spent some time talking with Jake at bimmerfest East talking about the development and testing ect.

One thing is and I know you see this is that their manifold is directly inspired from Leens week at Steed Speed. Just google "n54 Steed Speed" and you will find plenty of threads of PTF and now Motiv guys drooling over the prototype design for the N54. Fast forward a few years and they have build one.

I do have faith in Leen to build one not just because I did win a manifold from him but i have been following his work form the HPF days and seen his work on other cars and its always top notch. Also he is not afraid to update his manifold designs and make new revisions for improved performance.

The mani is going over to CES once the prototype is finished. Leen has not sent me cad designs but once I receive some pics of the prototype and if he wants me I will post them up and keep the thread updated. We were talking about WG placement last night, thinking of going on the front face, he was suggesting two 40mm WG as opposed to one 44mm.

I'd vote divided WG flange up to a single 44mm personally. Two 40mm WG is overkill and unneeded.

All their Twin Scroll flanged manifolds are divided all the way to the turbo, that is the only way to do a true twin scroll manifold, and get the benefit of the pulses.

I agree I was mixing terms. We need to figure out a way to differentiate twins scroll manifolds from twin bank single or twin scroll manifolds. That was what I was trying to use divided for. As in divided banks.

I am not following. If you have the manifold separated all the way to the turbo the banks are divided, its essentially the same thing, if it would fit, you could run their Cummins T4 Manifold on the N54, and put O2's in each bank and it would work fine. The do not need to change their design to make the N54 manifold work, just change port spacing, flange, etc, etc, etc

O2 placement in the manifold will impact per cylinder readings. Not sure how the internal runners are shaped but log style like shaudfabs will work completly different then Motiv's. As for steed speed we will wait and see. If I was getting one I would prefer it in 304L or 316L though.
