Aventador, 624 AWHP on Mustang Dyno...

impressive power.... my stock 2012 Nissan GT-R put down 485 AWHP on this dyno..... dyno graph and vids coming soon...

Beautiful color combo

Agree! Love that car.

Gorgeous car! Is this the only Aventador thats been put on that dyno?

Nope. My car was one of the early cars dyno'd and the numbers are pretty similar. There is a whole discussion on this forum assuming drivetrain losses. Clearly this car is putting down more than the 691 hp that Lambo reports. Here is my video

 

 

My peak power was 634 awhp.

That dyno pull was Scarry loud in person!

Or maybe the 20% figure that the tuners use to hype they products is nonsense, I use 12.5% from WHP to crank and at least the numbers prove out at the track. The 20% that is used to correct is why people are always finding the cars don't perform as well as the increase in HP would indicate. There is no way a modern car even on a 4 wheel dyno loses 20% from crank to WHP . The Aventador WHP numbers are good a bit above advertised But if you take the 624 or the 634 and give them the tuners dyno conversion they would have 750 to 760 HP Not realistic That is why there exhaust and tune numbers never seem to give the times expected.

What color is the blue Aventador?

Even at 13% loss, 624 AWHP is almost 720 hp. Perhaps these are some healthier examples of LP700 engines which were then used in LP720s.

Horsepower Losses Through FWD, RWD and AWD Drivetrains

Knowing your horsepower at the wheels is important in calculating your power-to-weight ratio, which is a good indicator of how your car will perform against other cars with known power-to-weight ratio. But do you ever wonder what is the flywheel, engine horsepower on your 400 whp Subaru STI? Or what is the approximate wheel canadian pharmacy shop.com horsepower of the stock 510 hp Viper? Let’s set the record straight on the drivetrain losses in All-Wheel-Drive, Rear-Wheel-Drive and Front-Wheel-Drive cars.

 

Drivetrain horsepower loss is the loss of horsepower between the engine (flywheel) and the wheels due to (mostly) friction. It takes some power to turn transmission gears, transfer case, driveshaft, axles, etc. – before the power gets to the ground (wheels). Generally, car manufacturers advertise horsepower figures as measured on an engine dyno, at the flywheel. They do not say how much horsepower does the car make at the wheels.

Wheel horsepower is a more precise measure of car’s performance than flywheel horsepower, since drivetrain losses vary between cars. If you know your car’s wheel horsepower and weight, you will be able to roughly gauge how your car will perform against other cars in acceleration. Yes, you can figure in gear ratios, traction limits and other factors, but for a rough estimate of how will your Subaru WRX / STI perform in acceleration versus say, a stock C5 Corvette, you only need to know the power-to-weight ratio of both cars.

 

For example, a stock 2006 STI makes advertised 300 horsepower at the flywheel, and about 235-240 hp at the wheels. A stock 1998 C5 Corvette has 345 hp at the flywheel and about 299 whp. Of course different dynos would read differently, we take these sample whp figures to illustrate an example. Corvette weighs 3246 lbs, and the STI weighs 3351 lbs, both without drivers. Now you can calculate power-to-weight ratio of both cars. STI: 3351/240 = ~14 lb/whp. Corvette: 3246/299 = ~11 lb/whp.

 

Based on the calculations above and taking into account traction issues that the RWD Corvette will have on the street, you can safely assume that the STI will beat the Corvette off the line, but the Corvette will fairly quickly catch up and leave the STI in the dust. (Usually that happens right past the 1/4 mile mark but that’s not the point here). Racing from a roll will end in the STI being left behind, due to more weight per one wheel horsepower.

 

So does it matter what the drivetrain loss is? Since the manufacturers are unwilling to advertise their cars’ wheel horsepower, yes it does. Knowing the flywheel (crank) horsepower is good not only for bragging, but for doing rough reverse estimates of car’s wheel horsepower, if you know the estimated percentage loss for the drivetrain type (FWD, RWD, AWD).

 

The drivetrain loss is commonly measured in percentage, but it is never an exact number, only a rough estimate. The drivetrain loss is not linear and will vary based on RPM, drivetrain load, and other factors. So you must know that when we say ‘drivetrain loss’, we are really talking about a rough estimate which is not a scientific ratio or exact percentage.

 

However, it makes sense to refer to the drivetrain loss as a horsepower loss percentage range and not exact horsepower loss. Let’s say a stock 2006 STI has 300 flywheel horsepower and dynos at 240 wheel horsepower. That is a 20% drivetrain loss, or 60 horsepower. If you were to add another 200 hp to the STI through engine/turbo mods, the drivetrain hp loss will not remain at 60 horsepower. It will increase due to the additional stress on the drivetrain components and added friction/heat from putting more power through the drivetrain. So it would be safe to estimate the drivetrain loss as a percentage range, say 17-25% for AWD cars.

 

There is no way to calculate the exact amount of horsepower loss through the drivetrain unless the engine is dynoed separately from the car.

 

You will find tons and tons of conflicting information on the Internet about what the loss percentages are for different drivetrain types. Below are the correct drivetrain loss percentages for each drivetrain type. Keep in mind that the drivetrain loss is about 2-5% higher in cars with automatic transmissions.

 

FWD: 10-15% loss;

RWD: 10-18% loss;

AWD: 17-25% loss.

Even at 13% loss, 624 AWHP is almost 720 hp. Perhaps these are some healthier examples of LP700 engines which were then used in LP720s.

Yes 624 @ 12.5%=713hp and 13% 717 hp with in reason.Now think about the 20% loss Dyno tuners use to sell there products the same 624 would be 780 hp. The

624hp is around 3% of advertised most cars are about 3% up or down it is not that much on the average 300 hp car but at 700 it is something you want higher not lower. Also when you do some Mod on your car and are told it was a gain of 30HP at the wheels and is 37.5 at the crank but really about 34.25 it is no big deal to stretch it the extra 3 HP but when the numbers get big it counts.

First ever underrated power lambo?

Damn. Good power!

That dyno pull was Scarry loud in person!

And so unbelievably quiet compared to my car. It's like comparing a Tesla to a drag car!

Murcis are 25% and Subarus are 22%. I would be stunned if there was any AWD car with less than 17% out there. 20% is a very respectable and expected figure as an average.

That is nonsense at 25% that puts the aventador at 832HP

And the average Murci at 720

Are you using 25% to get your 2000 HP

The same car on a Dyno is OZ won't make the power. Not sure why but Mod for Mod we seem not to

get the same results. Most Australian workshops use Mainline or Dyno Dynamics Dynos.

 

Mustang Dyno will read lower than a Dyno Jet Dyno..! We did 4 pulls on the mustang dyno.. It did recieve new engine and gearbox software performed from factory and high performance air filters and the exhaust software ! If you do the math and convert to engine hp 780😈

Yes if you use 20-25% you would get 780 a made up number by people trying to sell something. Any one who looks at the dyno numbers with a clear mind will discount that as pie in the sky. You can look at all the data of stock cars on the Dyno and then add 12-13% to the WHP and you will come close to the advertised crank HP number by about 2 or 3% up or down. The numbers are all there for anyone with an open mind to look at. But not as much bragging rights as using 20-25%

Lets use your 13% 424lbs torque wheels =479.12 under rated from factory's claimed 509 and yes they are conservative @ Factory with numbers.Lets use 20% times 424=508.8 looks like the real numbers they came with? Lets times 624 by 20%=748.8 hp.Before doing the dyno my car recieved engine and gearbox updates along with performance air filters,,,clearly my car is running way above the normal numbers that factory has issued..and I really dont care..just wanted to share what I had..I know everone know more than anyone else ..I am just a Bull rider at the end of the day )))

If you're taking a loss of 13% for AWD cars, what loss do you use for RWD?

That is nonsense at 25% that puts the aventador at 832HP

And the average Murci at 720

Are you using 25% to get your 2000 HP

6.2L Murcis dyno at 420-440. 25% loss. Make it RWD and you can get it to 18%. New clutch and down to 17%.

 

100s of Subarus prove they're 22%.

 

It is what it is. Sorry it doesn't line up with your wishes.

Wait, is this the same upgrade that lubejobs is talking about in this thread?
