    • 800+ wheel horsepower BMW F10 M5's and F13 M6's soon? BMS JB4 tuned S63TU hits 771 wheel horsepower on the stock turbos

      The S63TU V8 is finally pushing some boundaries. Tuning ability held it back for a while but it is now progressing rapidly on the platform. BMS (Burger Tuning) was able to get 770 wheel horsepower out of their F10 M5 development car on the OEM S63TU V8 turbochargers.

      Why is that a big deal? Because upgraded turbo hardware will easily push past that mark. @Terry@BMS believes 800 wheel horsepower might even be cracked on the stock turbo hardware with a bit more boost.

      The DCT is handling the power and torque thanks to the Dodson DCT clutch pack upgrade. Dodson is simply the way to go if modifying the BMW DCT transmission.

      Further details from Terry@BMS below:


      I'm sure these JB4 record threads are getting tiring by now... But just got back from dyno testing our 2015 M5 development car and I'm happy to report we raised the bar yet again.

      The car has a JB4, BCM, BMS intake, BMS chargepipes, BMS methanol (dual CM7 nozzles, straight methanol today), Dodson clutch packs, and around 95 octane fuel. Half and half 100 with 91. What's so amazing about this car is it runs factory turbos, factory exhaust system including all emissions equipment, factory rims/tires, etc. The mods can be installed and removed in literally an hour or so.

      Notes on the testing:

      1) Pushed boost up to 30psi to get power up to 770whp. What's interesting is that the JB4 monitors boost in both banks, while the passenger side bank produced 30psi the driver side bank running the same duty cycle produced only 27psi. If both banks could get up to 30psi we might see 800whp stock turbos and exhaust!

      2) With the dual CM7 on 100% meth the car is still fuel limited. Trims maxed out around 28psi and AFR pitched a little leaner than I'd like. This car probably needs dual CM10 nozzles.

      3) The BMS s63tu intake seems to be worth around 15whp peak at this boost level. Not bad at all.

      4) We tested the 60-130mph last night at 6.7s at 26psi, which produced ~720whp on the dyno today. The current limitation with improving those times is traction. On the factory tires that 6.7s took some driving. We will probably give it another shot at the higher power level but I think we're going to need R888's or drag radials to really use this power.

      5) The Dodson clutch packs are simply awesome. Must have for any DCT over ~675whp. We've had PURE TURBO install them on three of our development cars and they've done a great job with each.

        Dude $#@! yes! We have a customer who is looking to pick up an M5, we will do this plus our turbo upgrade, and see what we can get! Badass!

        That motor is just badass Click here to enlarge Good job. One thing though just like the N55 and S55 your S63tu given the throttle closure isn't actually boosting that high at the intake manifold and motor isn't seeing 30psi to make those numbers. That's pre-throttle. OEM TMAP in the intake manifold is a 2.5bar so it can't register boost higher than 21psi. With a flash you could remove the throttle closure and clean it up getting the same power without pushing on the turbos as hard, make more power than that at 30psi in the intake manifold. Might pick this up for my next daily!

        That is just awesome!!! I absolutely love this car man, it is just a sleeper cause nobody would expect this much power from it. The thing I like most is the fact that it is literally stock, and as you said the mods will only take a couple of hours to install besides the clutch packs.

        It's really an amazing car. I'd suggest it to anyone who has the money to burn. To make this power stock turbos with factory downpipes, exhaust, is simply amazing.

        On the tuning end we've managed to make more than any flash tuner has with them, frankly it's not even close, so if someone thinks they can do a better job on the tuning end go for it. Would love to see the bar raised. Once OBDII flash tuning is out we'll make a JB4 back end flash map. I'd like to at least remove the limiter and adjust the base fuel scalar. But until then I don't see us drilling in to our DMEs to bench flash them. It's too bad our model isn't a EWG one if those ever turn up I think we could make even more power JB4 only.

        Drill once for a world of opportunities on the flash side Click here to enlarge 3mm hole and suddenly no more misfires, ever! Don't drill and you get air going through through a 40% open throttle, inability to tune for higher than E20, etc. Different strokes...

        Terry - This is incredible. Two comments:

        1. I'd love to see what BMS could do with the MB V8TT or Audi V8TT. It would be really interesting to see which V8TT has more tuning potential stock.
        2. Do you think the difference in boost between the two banks could be solved ala inlets like we saw in the N54?

        Amazing. Congrats man.

        Thanks but we're not really interested in either of those markets at the moment. I'm sure they are both powerful platforms. Click here to enlarge

        The bank to bank variance might indicate a boost leak or something on one side or might just be normal variance given the high boost targets requested. Down the road we'll have the JB4 apply different duty cycles offsets to each bank via twin PIDs. For now we'll live with 770whp. Click here to enlarge

        It certainly is tempting.

        You should be able to do this on the X5M and X6M right?

        Now if only these things didn't weigh so much.

        Next gen M5 should be fun, seeing that the S63 is going to carry over. It will be lighter thanks to CFRP and aluminum components.

        The s63tu models yes. But not the s63 models.

        I know, it's a tank. But I think it still has enough power to run 135mph traps with traction. An M6 although slightly hideous is around 150# lighter. I'm excited to see what the next platform has in store. I'm hoping a lot less mass. But BMW often disappoints on those promises.

        Why?

        Because the s63 model is a lame-duck. Used on only a few models and with only part of the tuning potential of the s63tu. Click here to enlarge

        I understand it's been replaced but it should be easier to tune I would think, not harder.

        Why is the tuning potential less? It should be close to a wash.

        The s63 vs the s63tu? It's like the n63 vs the n63tu. Smaller turbos, weaker top end flow, etc. Cool motor stock and responds well to light tuning (like our Stage1) but it's just not built for big power like the tu equivalent.

        I didn't know the turbos were smaller. Really it's the same manifold, same displacement, same everything except for Valvetronic. The N63 of course is far less capable but the S63 and S63TU are almost the same thing.

        I've never really heard this before.
