    x37-47 / 2554-60 / C39 / ST280 - Small Turbo Comparison Thread

    Guest-only advertisement. Register or Log In now!
    Summarized Comparisons of Reported Results (as of 12/12/16):

    Original Cyborg: 235 to 260whp (depending on tune / fuel / mods)

    Pumaspeed X37: 250 to 290whp (depending on tune / fuel / mods)

    Cyborg C39: 260 to 300whp (depending on tune / fuel / mods)

    Pumaspeed X47: 270 to 310whp (depending on tune / fuel / mods)



    For those members that have turbo upgrades already installed here is a thread to let members know which upgrade you selected...You can also post supporting data and results here as well for others to review to help determine which upgrade best suits one's own personal goals...

    Which Turbo Upgrade do you "currently" have installed?

    And here are some specific turbo upgrade discussion threads on our forum listed below:

    Official Pumaspeed X-37 Hybrid Turbo Thread

    Cyborg Upgraded Stock Turbocharger System

    DHM "Quick Spool" GT290r Turbo Kit Release!!!

    PERON P3xx Twin-Scroll Turbo Thread

    Turbo Upgrade - GT2554R or GT2560R? Expectations?

    PumaSpeed's New X-47 Hybrid Turbo Thread



    Original Post (below):

    Where is the real comparisons? I am certain this has been beaten to death on this forum. But what I cannot seem to figure out is why no one is bragging with real data about their results?

    When you are doing a virtual dyno there is no standard for replicating the test. The gear your in, the temp, the location, the altitude, fuel, the person conducting the test, etc. Running your car using the virual dyno is useless if the tests are not consistent between those who are testing to use for any meaningful comparison.

    Lest not forget here in the US we measure torque and HP as torque in FT LBs, and HP normally in WHP as in at the wheel. Across the water, they measure in BHP aka at the flywheel, and Torque in Newton Meters. These are not the same. Normally there is a 15% variance between BHP and WHP in our car. Torque is about the same variance. Yes I know, HP is derived from TQ.

    And when reporting results, for them to be meaningful, both numbers need to be on the graph to show the relationship to each other in regards to RPM, and it would be really nice to see boost against RPM for your setup with your parts. Saying that your vehicle makes 240whp, or saying your vehicle makes 260WHP and 300FT TQ, without the graph means nothing, because if you are making all of your power at 5K, what is going on from 1Kto 4900K? Remember Boost is a measure of restriction. The higher the boost number don't always mean more power. If you have an efficient system, you actually can have less boost with more power.

    In addition, how about sharing everything you have done to the car in addition to the turbo. We almost need a form to fill out on this forum to keep it consistent.

    Obviously a tune is not a tune, and they are not the same between tuners. Where National Speed may go about it one way, DHM would do it differently and so would adam on the exact same turbo based on experience, and again it really matters where you are, altitude, temp, on the day you did it and using a real dyno and the brand of dyno you used. That's why Adam says buying the lifetime tune is important especially if you move.

    With any curve it is about "Power under the curve" not peak. For anyone who does not know what that means, when you are looking at a dyno graph, the higher your lines are over a larger area of RPM, the better. If your curve starts off on a 45 degree and climbs to peak at 5500, you are outside of the normal driving RPM range. When you are running around on the street, you cannot be running to 7 grand every shift, well I guess you could, but not as much fun IMO. You want your torque to come on quick and taper off as HP climbs, but if takes 5000 worth of RPM to get there your max power is only good for 2000 worth of RPM. AKA NOT A LOT.

    If you have real dyno numbers, not virtual dyno numbers, share them here, don't be shy and don't be greedy. This is not about I have more power than you, this is about being scientific about what we are doing. There are lots of people on this forum that would be interested, not to mention everything we post is available on the entire internet, so you would sharing your information to the world.

    Considering the variables, it'd be pretty unlikely for us to get direct comparisons between the turbos. Best we can do is generalize, no?

    You start with lowest peak and probably widest power band with the X-37/Cyborg, and then narrow the band/raise the peak, as you go up the turbo spectrum...

    ^This x100. The only way to get 100% 'direct' comparisons would be to install all of these turbos on the exact same engine and run them on the exact same dyno. It's unrealistic to expect and the people that would have the money to complete such a test aren't driving Fiestas. The best we have or will have are the people that have different turbos installed being tested however they see fit with wherever they're at on whatever day/time they choose to test them.

    Why are facts so scary? Gives people a basis to make a informed decision. I'm interested in a bigger turbo set up and am curious to see what might be the best.

    The best for me would be mean better pulls for highway use. Maybe someone can just tell me what turbo is suited for this. Or that this platform can't do it and stick with...

    Its certainly not happening with a virtual dyno.

    For me, if youre only looking for "numbers" Simply put: You want good spool and limited power less than or equal to 300whp, Cyborg and X-37 are your best options. If you don't mind slight delay in spool and want up to 350whp look into DHM quick spool kit. With these options it pretty much out does the other options but then again different strokes for different folks. if you want an NA like power band ATP 2554 seems to be the way to go up to around 300whp. Those are my suggestions from my research. I'm going a totally different route though but that's because of what I plan to use the car for.

    But as 2Cool and Dyno85 have mentioned there are tons of links and vdynos and dyno sheets and results all over the forum. the car is still new so there are a lot of new things be figured out. Easiest place to start? buy an AP3, get a protuner, and ask them to help you with your goal. Adam at Tune+ and Russ at DHM are both very reputable and will help you out with anything you need almost all the time. and can help you figure out what it is you need.

    People that buy these cars buy them because they are fun. Not to make enormous power(on rare occasions) so there will very rarely be any kind of direct comparisons of turbos.

    What is the biggest turbo you can fit without touching the stock fuel system? 300 whp is the limit?

    How does the x-37 and the ATP 2554 differ? If they both make the same hp? Thanks Temp.

    stock fuel system seems to run out around 320whp-ish give or take some lots of depending factors. GT2560R is probably the biggest you can go with stock fuel and actually utilize it. you can go bigger on the turbo BUT you will run out of fuel before using the turbo to its full advantage.

    As for X-37 vs ATP2554

    X-37
    cheaper
    SIMPLE bolt-on
    Faster spool(stock like-because it is a stock framed turbo same as cyborg)
    less hp on pump gas only but not by much
    with methanol and/or E30 is capable of making 300whp or very close

    ATP 2554r kit
    more expensive
    more hp potential on pump gas only
    Bolt-on but requires a few things to be changed(lines DV/BOV)
    spool is slower but acts like an Naturally aspirated power band
    with meth and/or E30 is capable of 300whp maybe more. not enough evidence yet.

    with the data we have now I'd always pick the X-37 over the 2554 unless you are looking for an NA powerband. or more power on strictly pump gas. The X-37 spools like stock but holds boost to redline, makes power, and is cheaper. Adam at tune+ likes it so much he stocks them to sell them to us. Its about $600 cheaper than the 2554r and you literally don't need to change anything but the turbo itself. but to each their own. some want more power than the X-37 can produce(like me) I want more than 260 pump gas. I'm looking for 300 pump gas and 350+ with meth. it really depends on your goal(s)

    This is STRICTLY MY OPINION. I have researched it quite a bit and that is what I have gathered, and others may have gathered much more and have different views but this is MY opinion. hope it helps.
