    • BMW F10 550xi dyno results with Dinan Stage 3 N63 software, Active Autowerke downpipes, and Active Autowerke exhaust

      Nice dyno results here showing how potent a tuned N63 V8 can be with just bolt on modifications. The car has Dinan Stage 3 software which although more aggressive than the standard Dinan software is not the most aggressive software available for the platform. Still, the software alone versus the baseline provides 45 horsepower at the wheels which for conservative Dinan is definitely a solid gain. This is then combined with the Active Autowerke exhaust and downpipes.

      The final result is 406 horsepower at the wheels for a gain of 81 horsepower at the wheels on the more conservative reading Mustang dyno. Solid power and gains. Those with N63 V8's have a lot of power sitting there just waiting to be unleashed.

      Graph, pictures, and acceleration videos below.

        I've posted these slips in numerous postings and slips.

        Plesse note my car is not the one with the tow hooks. Not sure how my posting got mixed in with his car.

        This was done at NY International Raceway Park
        78 degrees and driving around the box. Ac off, radio on.
        Brake torquing longer allowing the boost to spike doesn't really do much.

        Drove 43 miles to the track, teched and lined right up and ran this (hot lapping).

        Same thing I do in my GTR and run 10.60's @ 130.

        Allowing the engine to cool gets a .1 second quicker time but a slower short.

        I'd like to see a lighter driver get a 12.10-20 out of the car.

        In case someone wants the GTR slip posted - it's on GTRlife as well.

        Sorry it's at 127. The 130 slip was on cool down.

        What's done to your GTR? That's quick, very nice.

        I would think those are just bolt ons and a tune I was able to get 11.0 out of my stock GTR.

        So all these mods and still a bone stock m3 puts down 12.5. 406whp later it shows what the weight of a car does to performance.

        They are two different classes of cars but it is impressive the M3 does what it does without a 4.4 liter V8 and turbos on top of that.

        Hi guys,I have no idea how we or cross threaded here. Still scratching my head on it. The 550ix time slip I posted is a bone stock 550ix with Dinan stage II software only. Ran a best of 12.40 at 110. Stock exhaust, stock turbos, stock oil, hell it's got 1,000 miles on it. The GTR is just bolt on E85 - mid pipe, catted down pipe, full factory exhaust and am E85 tune. Adding a more aggressive tune and exhaust should get it into the 10.0-20 range.

        Btw - there is no bone stock M3 ever that put down 400 on a mustang dyno. A standard dynometer does not load weight. An M3 on this forum with RPI scoops, BMC Filter, Evolve Tune, Dinan Midpipe, and Vanguard axle back made 359WHP and 297WTQ on a Mustang Dyno.

        Of course the M3 makes less power, that's obvious.

        Lol perhaps for us but not for whomever posted...

        "So all these mods and still a bone stock m3 puts down 12.5. 406whp later it shows what the weight of a car does to performance."

        unless I read that incorrectly.

        Perhaps a bone stock M3 essentially equals what a heavier car is doing with more power. It's a power to weight issue. Well also the M3 has the DCT.

        Weird - so whose car is that with the AA downpipes and exhaust, and are there slips for that car?

        Not mine (DROPTOPP) or the one who posted dyno and time slips.

        mine is stock with a dinan stage II tune only.

        Typically in a 3500lb car - every 10 hp is equivalent to 1 tenth and every 100lbs is also a tenth.

        So if a car is 1,000 lbs heavier than a 3,500lb car it will be 1 full second slower.

        Gearing also has a lot to do with it.

        Yes that is the rule of thumb. Gearing and DCT throw a bit of a wrench in it.
