The text states:
"First new GT2RS dyno. Our friend Ekanoo strapped it down and it made 683rwhp. That’s a lot more than 700hp to the crank �� Check it out."


Typical ballpark numbers from crank to wheel are a 15% loss meaning the GT2 RS crank is putting out 805hp.
Again, I don't know that 15% is Porsche's loss but in any case this is very impressive!

awhp... crazy numbers

GT2RS vs 720 off the line - both seem to be at least 10% more than stated.

RWD: 10-18% loss
AWD: 17-25% loss

Modern drive train loss is not 15%. It's more like 8-10%. Still a strong showing from the GT2.

And that dyno (as most of them) is as accurate as my 5 year old daughter at math.
It's ok to use dyno to check before&after tune but never as a definitive HP check.

Any drive train loss data on rear vs front engine.

Things haven't moved on much have they, people still thinking a 7 second spin up of a drum can accurately measure the flywheel manufacturer stated full load hp of a turbo car - it can't you need an engine dyno for that and the engine needs to be braked at peak power with the appropriate cooling until a stable torque output is measured - it will be 705NM (which translates to 700PS) as stated and declared for EU homolgation - the more moot question is whether the motor can hold its 700PS on the track without the water sprayer, early indications are that it can't.

Winner winner chicken dinner.

Dynos aren't good for measuring BHP. Just deltas for before/after. It blows my mind people still think you can throw a car on a dyno and calculate accurate power/torque at the flywheel/crank. Doesn't work that way.

Latest Supertest from Autobild, they use the Insoric dyno system which is a set of wheel sensors measuring acceleration with software crunching the numbers using the details of the car, weight etc, it is proving amazingly accurate compared to chassis dynos.
