• What is a Horsepower Freak? New promotional short film from HPF

      Horsepower Freaks is becoming a giant for several reasons. One is that they have some of the most powerful packages available in the BMW aftermarket sphere. Another is that they have some of, if not the best, marketing in the BMW aftermarket. Part of the approach is controversial but the fact is you can not get away from the name and everyone does know it. Their build journals and marketing are basically the most detailed and well done out of anyone. The film is enjoyable and when Chris (owner of HPF) sent it to BimmerBoost, we told him we would have no problem putting it up.

        Do you see why it's ridiculous to bash the N54 so bad?

        We haven't even seen a bigger turbo setup on it yet and we're stuck on factory injectors! I think 500+WHP/500+ft-lb on STOCK FRAME turbos, internals and STOCK injectors, full torque by 2500-3000RPM is pretty damn good! The N54 doesn't have a HUGE aftermarket like the some of the other brands.

        The N54 is fighting an uphill battle because of new technology and building an aftermarket from scratch. So what!? I'm not even saying one is better than the other, it's just ridiculous to act like it's a complete joke, which is how you portray it!
        The N54 fueling limit is just one problem it faces. The S54 isn't running any stand alone ECU, piggyback as well.

        Nobody is bashing the N54. The N54 simply is not an S54 and never will be. A bigger turbo won't change the fact the torque falls off hard. A bigger turbo won't change the block. A bigger turbo won't change the lower redline. A bigger turbo won't change the valvetrain. A bigger turbo won't change the displacement disadvantage. Honestly, for a factory turbo motor I would have expected much bigger things by now. The S54 has made 1000 whp. The S65 is making much more power with less boost using SC's. You can't compare it with the NA M motors because they flow so well to make their WHP per liter. Uphill battle, like I said.

        The N54 has a bigger aftermarket than the S54 ever had.

        It isn't a complete joke, I respect it. What is funny is how some 335 owners call the motor the new Supra, please, that's a joke.

        Ok, I can give you all that, we all have different opinions obviously, but this one statement is completely untrue.

        A different turbo setup can radically alter the torque curve, even if the VE is only 80% at 7000RPM vs 95% at 5000RPM, especially if going from tiny turbos like the stock N54 to a fairly large turbo like a twin-scroll GTX3582r. The throttle body, charge piping and head all play a role but the main bottleneck now is the turbines, they are being over-spun and are even not so efficient at max engine RPM only running stock boost, hence the taper that is built in to stock and aftermarket programming.

        I should have phrased it differently as a big turbo will push the powerband more to the right. What I should have said is the cam profile won't change and the torque will still drop off hard due to the heads/cams/natural curve.

        The torque will drop but it would not be nearly as hard as what we have now, running turbos sized for 8psi trying to push 18.5-20! Plus, if you have the fueling to handle it, and the compressor is still within its efficient RPM, you could run a boost curve that countered that natural loss of VE.

        But yes, once the N54 gets big turbos, will we see people trying bigger throttle bodies/charge piping, ported heads, higher lift/longer duration cams, etc. It's only natural on the quest for more power. Click here to enlarge

        Not as hard but it still will. Heads, cams, they stay the same. Now, you can definitely start trying to address those weak points as well.

        Absolutely, agreed.

        lets make a list on bottlenecks on the n54
        -turbos
        -inlet pipes
        -small 2.5 inch at its largest intercooler pipes
        -no fuel to support 500+
        -no serious turbo kit

        Heads, valvetrain, cams.

        Anyway, the N54 has a long bright future ahead but let's get this back to HPF turbos and such.

        6-7 years ago my Supercharged bolt on S54 made over 500whp and ran a 11.9 @ 123mph at one of the worst tracks to have ever existed. I haven't gone back to a 1/4 mile track ever since but my S54 makes 940whp at 29psi currently. Traction is the only issue and trying to come up with a solution for a track day.

        So what is your argument here? Sticky is saying the S54 is a superior motor, that is the truth. The S54 flows incredibly well, with just a lowered compression piston/rod setup (and L19 head studs) you can make 800+whp safely all day long (I did it). As far as your TQ argument you are comparing a high revving motor with 1 turbo, against a low revving twin turbo motor. Another factor is that the N54 comes boosted already, whereas the S5 does not.

        You don't understand, development time for the N54 won't mean anything. IT WILL NEVER EQUAL OR SURPASS THE S54. The S54 is far too efficient to begin with. This is why boosted M motor are so much stronger per PSI of boost.

        Taza is making what, 950 whp? I mean that's insane whp and you think time will change things? It isn't a question of time, the S54 is a better power platform due to the design of the motor.
        Exactly..

        My 940whp at 29psi is a daily tune (granted on race gas). It was not a dyno tune, or dyno number setting. We could have easily put more timing, less fuel and more boost to achieve 1100whp but we did not. Im not after marketing. Click here to enlarge

        This is true although HPF is making the S54 sort of like a 2JZE market now that they are releasing pieces of their kit. More people are experimenting with the S54 now as well, ProEFI, Maximum PSI etc... Remember for years the S54 was dubbed the "blow up" motor and many people were scared to touch it! The N54 started off on a much easier foot!

        Of course I remember the bearing recall fiasco, I had a 2001 E46 M3. The motor got a bad rep but that was soon put to rest. The N54 started out easier being boosted but it just goes to show how what matters is the design of the motor to begin with and the S54 is just insanely efficient. BMW's best work, IMO.

        i got this vid along with an invoice...can't get away...guess i'll watch it.....












        ...meh

        i don't see whats wrong with refering to the s54 as the german 2jz

        Didn't mean to take attention away from HPF. The video was badass! Nothing beats some high-quality track footage with a car like their modified M3.

        The S54 is definitely on my list of favorite motors. I wonder what HPF could do with an e46 M3 focused on strip duty....

        Their best passes so far were set with their orange shop-car, right?

        You have to admit the CAN-bus setup for the N54 is pretty cool though. It's response time and the way it controls throttle, a/f ratio and ingition timing to keep itself near the limit makes it almost hard to blow up.

        Yes, they have been trying hard for 10's with it. They even changed the turbo, etc.

        I think this sums it up kind of. S54 is not competitive any more. Not in racing but neither in the market place. Ford T-model received a lot of prizes, but it's engine is not good in today's standards.

        S54 is very inefficient in comparison. Efficiency is the ratio of output to input. N54 is way ahead S54 which is showing its age. NA engines are not competitive or efficient. Have a look at the new F10 M5. Now that is efficient high tech modern engine technology.

        I don't know how you define an engine, but to me it is not the iron block to which you upgrade all the internals and slap a huge aftermarket turbo...

        it depends on your definition of efficiency. if you mean HP/Liter, S54 is ahead.
        give it the same boost as N54 and the HP will be doubled.

        Efficiency has nothing to do with displacement. It is output/input ratio.
