    • 712 rwhp F80 M3 on pump gas with no methanol and no port injection on stock pumps and stock S55 engine internals

      Well, how about this? The BMW F80 M3 you see here is running the KRATOS KRAS55Bi S55 turbochargers. We know those turbos make power (they hold the S55 power record) but how about some ridiculous pump gas and stock fuel system numbers?


      This is 712 horsepower to the tires on factory S55 internals, the factory transmission, and the factory fuel system without port injection or methanol assistance:


      Note, the graph states 750 clutch which is 712 wheel horsepower.

      This is on roughly ~93 octane pump fuel. The tuner believes they may be able to get 750 whp out of the factory fuel pumps.

      You will notice the power curve is beautiful and before someone misinterprets the graph the torque is displayed in Nm. Correcting 915 Nm to lb-ft gets you 674 lb-ft of torque at the crank.

      This is the strongest 93 octane S55 posted without any sort of octane assistance.

      WHP Graph in PS and Nm:

        A claim like this is hard to believe without some logs. Good power for sure though.

        Crazy if they can get that much power on 93.
        Even if theres a bit of meth and upgraded lpfp its good.

        S55 and n54 is bmw top dogs for sure... but it's cool to say hey look at what we did. But can the s55 sustained that power for the long run. I'm more concern about the breaking points not maximum performance. I wanna be able to drive and push my builds for more than 20k miles

        not quite, for stock internals a lot of bmw motors seem to reach their reliable limit around 750whp. S54, n54, s63, n54, s55. As far as bmw top dogs, that would likely be the motor that holds the most records in which s55 and n54 have a way to go.

        LOL, that 750hp at the clutch is magically 712WHP. Santa claus is also bringing me some cool gifts this year for Christmas. Whatever happened to 15% for drivetrain losses which is standard which makes this 637.50WHP which is right in line for what a very good running S55 makes on 93 octane with upgraded turbos. Sorry there are no "magic" turbos that all of sudden are going to add 100WHP to octane limited fuel. Click here to enlarge

        This is my car and mysterically ended up in this forum without me posting, lol!

        Yes it's making north of 700wheel on pumpgas, I added a can of octanium to a full tank just to be on the safe side. It's running 24 psi tapering up to 28-29 psi from 6000-redline.

        I'll go with some meth in tank or e85, should make easy 740 as I've done that before with WMI and E30 in tank.

        No mystery at all KRATOS sent it to me.

        Indeed it is. Don't forget the M3 did that at 11.5:1 without any DI bull$#@! and an 8k redline

        LOL, just breezed right over my post. So now the customer is admitting to having added octane booster to the tank, but this is still posted as being done on pump gas. Gotta love the click bait though...

        He actually posted he used the octane boosted on his IG post. There was a miscommunication in how it was presented to me but the tuner isn't hiding anything here.

        The car is making over 700 whp on pump gas and we'll see how far they get it as they are still tuning it.

        Why are you trying to rain on the parade?

        That's why I said I needed to see logs. I have GC+ turbos and the most we could get out of them was right at 630whp on pump gas.

        These are not the same turbos...

        A friend of mine has these Kratos turbos as well though and he didn't manage much over 640whp on pump. And that was after adding an gallon of E85.

        That number is very low for pump 93 with a gallon of straight E85 even on a mixture with a full tank, let alone straight pump 93. His quality of fuel may not be up to par or his IAT's must be very high as most of our customer see an average of 665whp+ on pump 93 on it's own during the hotter months as long as they have good quality cooling components to keep IAT's down. Also, keep in mind that our powerband is completely different and doesn't drop off after 6250-6500rpm even if comparing similar peak dyno numbers from other turbos. Published 93 octane pump gas dynos from your turbo brand shows 600whp by 7k rpm which is an average of 65+whp less than our KRAS55Bi's on the same fuel at the same rpm.

        For example: https://www.bimmerboost.com/content....on-93-pump-gas

        By the way, who is your friend if you don't mind us asking? We're in pretty close communication with all of our customers regarding their results and tune logs. Seems a bit strange he didn't reach out to us after such low results as the majority of our customers would've contacted us immediately for advice or help knowing these results are below the standard and capabilities of our turbos systems. We'd be more than happy to help or assist him in any way possible.

        Rather stunning. Anything over 650 RWHP on otherwise stock components is major. Surely the water intake cooler was upgraded?
