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:...

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...

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...

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...

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...

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.

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...

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.

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...

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
10-06-2014, 10:56 PM
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.)...
10-06-2014, 10:43 PM
Just to clarify, peak torque does NOT equal peak acceleration. Peak acceleration occurs when you have the highest mechanical advantage (i.e. lowest gear) and the engine is operating at peak...

If you think that the majority of a race (I am talking on a race track, not a drag strip) is spent at 90% of the maximum RPM of an engine (assuming regular 6500 RPM engine here) - I don't know what...
10-06-2014, 08:46 AM
Power under the curve matters in nearly any race, and cannot think where it wouldn't matter - unless you are talking a 2 shift 1/4 mile. It's the ONLY thing that matters. Average power (area) /...

I am glad you wrote this, I felt like what Dinan did was incredibly shady; quoting crank numbers in comparison to WHP for their "gains".
The math on their own website made absolutely no sense,...
