• The strongest automatic N54 BMW 335i stands at 711 wheel horsepower until proven otherwise

      A bit of controversy ensued last month when the N54 motor hit a new peak horsepower record on the dyno. Why? Because different dyno machines in different areas will read differently. If one person uses say a Dynojet and another uses a Mustang trying to compare the two is somewhat like trying to hit a moving target. Well, we can alleviate some of the controversy now as this particular car went on a Dynojet and posted a new automatic transmission Dynojet record with a 711 wheel horsepower pull.


      That is of course less than the 753 wheel horsepower that was hit on a Dynomite dyno and it should show very clearly that different dynamometers read differently. There is no established standard but BimmerBoost does prefer Dynojet numbers as it is the most popular dyno. There are enough of them out there in the world that anyone should be able to find a local machine to use and we are glad BimmerBoost member @Ak335i did so.

      So, while this does not exceed the 725 peak wheel horsepower number Vargas Turbo Technologies achieved with their Stage 3 turbocharger kit we are now to the point of splitting hairs as whomever is willing to push their motor (and transmission) further will have the record. This being an automatic car means it is far more difficult to upgrade the transmission and get it to hold the power. In that context this is a major development for the automatic N54 crowd and hopefully they have a transmission solution soon.

      Now the question is, who will be the first to push past the 7XX range and who will end up raising the bar that is now a bit stagnant in the 7XX range? All BimmerBoost can say is when it happens our readers and members will be the first as always to know (and the ones who are raising it anyway).

        Ok all fixed should look good.

        It would be cool if @aflatau and @Ak335i hit the same dyno at the same time. We'd learn a lot more that way.

        he hit 711 wheel at 6100 RPMs, he had another 1k rpms to go.. he could of easily beat my numbers.

        Ya would be a blast. Sucks all the fast e9xs are like in diff corners of the continent. I'm all done dynoing until I swap the tranny. That was like a yolo spur of the moment thing crossing my fingers it held on there haha.

        Then I go race tonight. My car gets used and abused. Tranny slipping? Ok turn up the boost and let off between shifts. Lmao. #ratchet

        6100 no $#@!? wow yeah the numbers add up

        that's insane.

        what's the overall torque curve looking like?

        @Ak335i did you get a pic of the whole graph? Probably useless for the most part with trans slipping and wheel spin but still...lol

        This all started with a street race on our way home from the track followed by a puff of smoking then he makes a comeback as though he was Goliath.

        This is like Winnie the Pooh that died and then came back as Doomsday

        I mean Dan is like so far head, I mean light years ahead, to the point I don't want to build a car I want to build a dam rocket now....sigh....I might as well go chasing after a Devel Sixteen

        We really need the whole graph, especially if it is to count for the record.

        Sent it to Matt. Im.about to head off to airport he can post it when he can. Or I'll have to post tomm when I'm on a computer. The graph is rough as we brought boost up slow to save the auto and it has clutches slipping and tq conv. noise above 5800. So we let off on one of the runs. Hhaha.

        Basically the auto does the same thing above about 675whp as the manual with dmfw. The noise causes false cylinder 6 misfires. So this was a yolo dyno I'll be going 6mt most likely

        And incase I didn't mention for anyone in naples/ft myers check out Nür Performance in Fort Myers. They are a Protuning shop and do all types of cars as well and fab work etc. Great guys

        I seriously pray the N54 stock conrods and studs etc are better than those in the Mezger engines as I have been shown some spaghetti like rods from 996TT at lower whp and talk than this
