Well, no fuel-burning car is making 400hp at 0 engine speed so something is off. Could be as simple as the x-axis offset (guessing here as I've never operated a dyno but have seen a graph or two), but "I think they know how to dyno" is meaningless to me since first off I know nothing about those two shops and they screwed up this chart.

Please take a look thru my past posts in this thread, have been supportive from the start just curious about this odd lookin dyno graph

Ok mate, fair enough. Yes I heard that about the Mustang dynos too. Solid power/torque figures if that's what it was making, ignoring the first section of the Dyno graph. Can't be making anywhere near that power at 0rpm.

Not doubting their capability to dyno, but the chart has probably been chopped off the beginning section and axis labelled incorrectly.

It's impossible to make several hundred horsepower at 0 rpm.

This isn't a electric motor,

Appreciate your support! It is a good point but I'm certain that these guys know what they're doing, its probably how they configured the scale. Sheepy are some of the best in the business.

So, just to make sure I'm up to speed here. Velocity posts a cool video about an N54 advertised as making a certain amount of power. Some crusty old men complain about YouTube videos and don't watch it. Other crusty old men say the HP figure is an obvious lie because the driver is able to maintain traction and control of this car. This is where I start to wonder if this car has been fitted with a variable input accelerator pedal. That would be the perfect mod for a car with lots of power, so the driver could give as little or as much throttle as he deems necessary. And if the driver is any good at using this mod, he might be able to adequately control the car, despite its high power. Now the dyno sheet is under scrutiny because everyone agrees the x-axis isn't scaled in any logical way.

Velocity and TWilliam, for my own education, can you ask Sheepey Race what's up with the x-axis? Graphing for crank HP doesn't exactly help their credibility either.

This is a public message forum. We are all just discussing a video someone posted. As long as people keep things civil, I don't see the problem. If you don't want people to critique a video.....don't post it on a public forum. 👍

If you just want to post up a video, and don't want people to comment....that's what YouTube is for.

If indeed equipped with variable input pedal probably is bolted to the floor as I don’t see making over 400hp/400tq as soon as you start the engine! Pick on me for misspelled Dragy and other stuff that I put myself into a corner but that device will give pretty accurate numbers of horse power the car is making. Doesn’t even have to be 0-60. Could be 40 to 100. Or I’m wrong again?

I agree, but some posters were not civil and some people implied that the video was a complete lie. I believe that it's totally reasonable to prove to a critic that the video is not a lie. Also, its extremely difficult to capture the sensation of speed in a video, even the professionals struggle.

I personally do not understand the mentality of people who are rude to other Internet users. Criticism is good but the manner in which it's done makes all the difference..

[iqraceworks]

Maybe it's just the way the video was filmed......but I will say that it sure doesn't act or sound like it's putting down that kind of power....but who knows, maybe they put a mild tune in it so the guy driving the car didn't wrap it around a telephone pole.

When you compare that video to some of the other videos of single turbo 335i's putting down 650whp.....the difference is pretty shocking.

But like I said..maybe they had it dialed way back in that video...

It wasn't dialed back at all. The car is a missile but we can agree to disagree..

That's possible, also can't really tell how much power a car is making by watching a video, plus we don't know if the driver was going wot or taking it easy through the rev range.

I dunno about using Draggy to get an idea of power figures, real world performance yeah,

What if it spins the wheels, due to traction issues, you end up with poor 0-60 or something 40-100 times, does that mean the car isn't making the power?

Oh please, I'm not picking on you. I just think the guy calling for the dragy race should know how to spell it. I'd love to see a 60-130 time from you and TWilliam. How about you post yours first?

It's a formula which I don't know exactly but factors in the 1/4 mile time, trap speed, car weight, tire size and gear ratio. It will give you pretty good number of engine output. E9x with 650whp should be in the mid to high 11sec. But yes, you are correct, if traction is an issue numbers won't be accurate. I was introduced to Dragy last year and I tested 1/4 mile, and the numbers from various inline calculators were pretty close to what the car dynoed.

Enhanced or true 60-130 time ? I really like this thread. The guy said to line them up and we are over 2000 miles away. Dragy is more realistic. I misspell often, English isn't my fist language, and also sometimes this Iphone is changing the words and I click send without proof reading.

OP any clarification from your dyno place?

Yeah, lots of online calculators for that. I think the trap speed formula is more accurate than the ET one simply because there are so many variables that can slow your ET down, but you should trap pretty consistently. I love my dragy, but I find launching my MT xi to be quite challenging. Here's my best 1/4 mile so far.

Well more power to you with your multiple languages! Now I just feel stupid. Also, what's an enhanced 60-130 time? Are we talking about fudging the data?

Thanks for the advice, dip shit.

No, knowing languages doesn’t make you smart. We all can learn. Yes, when I say enhanced I refer to the graph in this thread showing 400hp/400tq+ at idle. Or turbo compressor maps when manufacturers want move product. Happens all the time. Launching manual is very challenging, especially our cars. It will either spin the tires, wheel hop, or bog, or grind into second. I have MT and AT and the difference is significant. I honestly feel little bad for this thread taking a wrong turn, obviously I’m partially to blame, but I will say again, that car in video isn’t very convincing of the 650WHP claimed.

My 07' 335i on an MHD E40 tune is crazier than the car in the video..and it's probably making only 450whp. If that car in the video was truly making 650whp...it should have been lighting up the tires in 1st, 2nd, 3rd......but it wasn't. It sounded like it was accelerating just like any normal FBO 335i with stock turbos.

I could really care less either way.....I know a 335i with pure turbos makes big power, no doubt. Maybe it was just the way the video way filmed....but that car looked really weak. It just sounded really slow when it was accelerating......nothing like a true 650hp car.
