    The key is octane, not the brand of fuel - as said in the article. Point is, timing will advance on an engine (especially a performance oriented one) - and timing advance == more power.

    Check out...

    When I say "archived on my computer" - computer should be plural. I have 4 computers on my desk - and a bunch of mining machines, and probably - idk, 15 hard drives... I am making it sound worse than...

    Ha! Thanks, appreciate it.



    I have a bunch of stuff (mostly S54/S65/M3 related) archived on my computer from over the years; this was from the June 2002 issue of Evo, and images were grabbed...

    An S65 or S54 (and nearly any modern engine) will definitely make less power with 89 octane vs. when 93 (or above octane is used). Our fuels in the USA are garbage - we rate our octane "weirdly"....
  5. A better way of saying it - "in the real world",...

    A better way of saying it - "in the real world", peak power is when you achieve peak acceleration in a car - at a given vehicle speed. It is much more pertinent to the wheel (err real) world than...

    It really is. It's a damn good tuned engine, that's for sure.

    Amazing job, amazing car - and amazing power curve. Looks like it would be a fun car to drive everywhere. :)

    It is because of what you said - if the torque is being measured in nm instead of ft-lb. If you look at 5252ish, and see what the power is at (looks to be around 630ish?) - and then convert what...

    Dude, holy $#@!. I am shocked you still aren't getting this. The vehicle is INCREASING SPEED - here, just read this, there is a mathematical proof and all:...
  10. I think you are trying to say that if your car...

    I think you are trying to say that if your car had 1 gear, and you were accelerating in a 335i having a torque peak at 1800 RPM, that it's acceleration would be highest at this point. IF YOU DO NOT...
  11. You are wrong, and at this point I think you are...

    You are wrong, and at this point I think you are trolling. Please read the following - if you haven't already. I can't even believe you are being this stubborn; have the audacity to "LOL" at things...
  12. You still aren't understanding. No, this is not...

    You still aren't understanding. No, this is not true. Think about it from the point of conservation of energy. When you are creating more power, it has to go somewhere. If the torque is lower in the...

    I have a degree in CS, and a minor in Physics - and completely understand the equation. I am not forgetting about anything - you cannot create power from gearing. You can create a mechanical...
  14. This is my last post here, and sorry to come...

    This is my last post here, and sorry to come across as "attacking" - as that is not my point, I just want to clarify - as this is one of the most misunderstood things in regard to...
  15. Yes, peak instantaneous acceleration in any given...

    Yes, peak instantaneous acceleration in any given gear occurs at peak engine torque BUT peak rear wheel torque at a given tire RPM occurs at peak power.
  16. It is all that matters. Torque is TIME...

    It is all that matters. Torque is TIME DIMENSIONLESS - it has NO MEANING in this regard. I can get a 50 foot pole - attach it to a bolt, stand on the end of it (I weigh around 200 lbs), and create...
  17. Exactly.

    Exactly.
  18. This is absolutely incorrect! I think we might be...

    This is absolutely incorrect! I think we might be saying two seperate things - but the only thing that matters is horsepower. Torque has no time or speed component. This is at the engine.

    Now, at...

    I think - just my .02 cents (and probably last 2 cents in the thread) - that this is also what separates a car meant for the track vs. a fast car for the street. One has a predictable power curve...
  20. Average power = Power under the curve! That's...

    Average power = Power under the curve! That's what this is all about.

    If you integrate a function that could somehow represent the power curve, that is by definition the average power a car makes....

    subaru335i - Agreed. On both the cohesiveness of the threads (which is partially my bad) - but if it clarifies, we Dietcoke are talking about engines and power curves, it just got a bit sidetracked....

    And, yes - the engines made at M GmBh are indeed built for a race track. That's the entire point of the "M". That's the difference here - one engine is completely different from the other - and I...

    What the ... That's what you took from my post - CVT transmissions? I race cars - and have raced karts since I was VERY young. I KNOW I spend a LOT of time in my cars below 5k on the racetrack - what...

    Wow... That's a terrible crash - I was wondering how he ended up in such bad shape, this helps put that into perspective

    And to make things more confusing (probably where this whole idea comes from) - the only thing related to an engine's peak torque - is that it is a.) operating most efficiently at this point, and b.)...
