    also curious about this one!

    it was such a huge problem at first seemingly.. but since then, little to no noise on the subject?

    people were spacing it out for a while, now.. seems fine just banging them in right in front of the port??

    not quite..

    i just don't follow the illogic of making a single scroll manifold, when a twin scroll version would be relative childs play given the design, and be.. well.. better?

    arguing with someone saying a single scroll will outspool AND out power a twin scroll on an equivalently high quality manifold with good tuning in a physics defying feat just boggles my mind.

    I'm not sure what you're talking about, the Proven Power manifold is different, and the fabricator had not even heard of FFtec before when he did mine, let alone Ak335i.

    If that's not your reference, then my bad, and no, obviously lots of products are replicated, there is really only so many ways to do something. Honestly surprised no one else has come out with a twin turbo kit yet. Too much money for two turbos maybe?

    lol, so lets compare PTF spool on a larger single scroll turbo to Terry's top mount smaller turbo twin scroll. Let's face it, if you want spool you're going to sacrifice some top end, and vice versa, it's just a matter of personal preference and finding what's best for you.

    From what I've seen though, the PTF kit is already spooling as fast or quicker than the FFtec top mount TS 5862, and that's with an HTA3586r turbo, which is capable of significantly more power.

    Twin scrolls take up more space and increase costs. I haven't seen any benefits yet, besides being able to install the actuator flap that only opens at higher throttle, essentially cutting he AR in half on demand.

    exactly

    compare terry's top mount to fastGTI's.. Hence i'm adding the qualifier 'equally high quality twin scroll manifold'

    imagine the PTF one with a twin scroll.. logic dictates spool will be improved even further. Can i confirm this with hard evidence? No.. but no one can confirm the single scroll is better than any way, either (other than a couple percent more peak power potential from the single scroll housing), so we have to go off other available evidence which indicates on all other platforms, engine configurations, manifold styles, that twin scroll is better overall (to the tune of 10-15% odd better midrange), all things equal.

    benefits have been shown over many platforms and race teams re twin scroll vs single.. heck, even a full whitepaper from mazda (though magic dorito motors treat things somewhat differently), it's a moot point.

    one of these single scroll manifolds with a QSV could be pretty interesting though.. that would be an interesting comparison.

    Fastgti69 is using a much larger turbo than Terry, and a different kit, not even comparable. FFtec looks like to have less piping overall, which means quicker spool from the manifold, and Terry is using a 58mm turbo compared to a 64mm comp. What would be interesting is a single scroll 58mm turbo on the PTF kit and compare that to Terry's setup. Only a matter of time till we start seeing dynos and logs from a variety of turbos on a variety of different kits.

    ??? Takes up more space? A properly built TS manifold takes no more space than a SS manifold does, the problem is the N54 is stuck in the pile of snakes manifold game right now, its good to see it may finally be ending. The manifold below takes up basically no space, and costs $295 dollars, anyone else want to argue twin scroll takes up more room and is expensive?

    Funny it should come up. I'm throwing the same comp 6465 turbo on our FFTEC 135i to make sure the 135i is quick enough to stay ahead of all these new single turbo cars coming out. I'm really hoping spool doesn't take too much of a hit. I have tons of data on the 5862 most of which I've shared so it will be a great new datapoint.

    I also have lots of experience with a divided log style turbo twin scroll, aka the Vargas N55 Stage2 turbo, so those datapoints can also be compared.

    IMHO cast divided log manifolds should be more durable for the long haul and should be easier to mass produce, while tubular manifolds should offer superior performance especially at higher RPM. But as with anything the devil is in the details.

    This is a good starting point for reading about various manifold approaches: http://www.turbobygarrett.com/turbobygarrett/log_style_vs_equal_length_manifolds

    You never disappoint when it comes to data Terry. I'd have more data collected on mine by now if I wasn't so damn busy with work. Hopefully dyno this Saturday, and some decent street tuning tomorrow and Friday. Can't wait to see results of your 6465 on the the fftec 135i compared to the VM single turbo kit with the same turbo!

    much larger with identical spool (well, close enough to) (unless i imagined seeing an overlay lol)

    perfectly comparable.. in fact, it's an even better comparison considering the turbo is larger Click here to enlarge

    still has a good chance of hitting the steering rack - without looking, the wastegate pipe is the biggest worry with going back (ie closer to the bulk of the rack) and out (again, closer)

    can't know until someone actually measures how much room is where though/tries to actually fit something in!

    I dont know who started this thread, but thank you. I have been working on this kit for a long time and am very happy how it turned out. Its only fair that I not post any pricing or purchasing details until I become a vendor. That will happen when the first run of kits are on the shelf and ready to ship. I would however like to post pictures of progress and dynos of the kit in the mean time if @Sticky will allow it. Thanks to all for the kind words about the kit and I look forward to being a part of the N54 progression.

This isn't an announcement from the company just pictures so you do not know if its even released, they could have dynos for all we know or they could not. They may or may not release them when they release the kit.

    But just from looking at your kit, your solid numbers came after pictures of your kit were out, which is just what this is. You also had a dyno that was not to impressive released prior. For you to write what you did is a bit ironic because the same could have been said about your kit which was the first of its kind, in your car, with no dyno for a while. Pictures are just that, Pictures.
    Thank you Chuck, I respect your kind words an honesty. I am deeply sorry if I came off that way, I have just always been like that. Even before my vendor status, i would always like details of everything from every angle etc. I will stay quiet and lurk, you are correct my behavior has been sub-par.

    One thing I would like to clear up though. First day I got my car, I posted a new thread. It had pictures, 3 logs, and a video hid nothing. Got a dyno a couple days later with Terry, and yes hit a dissapointing 593 but I should have known better. I had logs, videos, and graph posted. Next week after that, drove the car to shift sector and raced. Car did well, and I was loving it. Became a vendor, people were not happy with numbers and kit release. I got clutch and meth kit, redyno'd put videos and logs again with a new graph lol. Get my point? I really never hid anything and posted right when I got info.

    Actually, quite the contrary. I have been working on Terrys' car the past two days and the manifold runners are longer. They swoop down, then back up. This is the overlay of my car dyno, and Terrys car dyno same psi. We spool pretty much identical, and I have about 60whp through the rev range. 58mm vs 64mm so now, we want to test and see if it's the hardware or the turbo that is compensating the spool.

    That's the easy part, a new wastegate dump pipe can be reconstructed to clear the rack. The biggest hurdle for all top mount kits have been trying to get the downpipe to clear.

    Am definitely going for this when the sale opens!

    You are correct, but the owner of this kit, or the fabricator, or whatever you want to call that person did not make this thread, actually did just respond in this thread stating he wants to share any and all info upon its release so I wouldnt jump the gun and question the depth of information on the kit until all cards are revealed upon release.

    Your kit looks great though. One question though... has anyone came anywhere near @Terry@BMS 's 5.99 60-130 ??!?!? That is what matters to me!!! Click here to enlarge

    1000 times cleaner than a top mount. Just my opinion, not a fan of bling in the engine bay, nor of the extreme of amount of radiant heat you are building up in the engine bay with no real way to escape

    That'd be me, sorry if I jumped the gun but I thought it was too awesome to not share on here. Been following the updates on FB for a while now, I look forward to seeing more progress pics and dynos!

    Question, not a statement, but heat rises so wouldn't a bottom mount produce more heat to the engine and accessories than a top mount? Top mount would great soak the hood more directly than ambient components. Probably flawed logic.

    I'm purely speculating but it looks like there's more open space with a bottom mount along with better existing heat shielding, instead of tucking it up in the upper corner surrounded by plastics. Airflow through the bay looks like it would flow out through the bottom since the hood is more or less sealed.
