Dyno results

Dyno ride of bone stock sport 2014, 8speed. It was made at the same stand as I did.
340 ps (338 rwhp)
So it really seems 8 speed has very good power transfer to the wheels.

340ps is 335 hp at the wheel, with 390 at the crank to start with is right around a 16% loss, not bad at all.

Actually the problem of catching of downshifting is still open. If it would possible to fix the gear with any custom tune by setting at quasi manual D4 for example, the numbers would be higher. So as mine. Not too much but still may be 5-10 hps more.

HP/TQ always bi-sect @ 5250 rpms. I don't see that here. How does this dyno work?

Sorry, haven't good understand what you meant, can you explain about bi-sect?
This is as usual dyno stand with 4 rollers, but I don't have its producer in memory. This is their site:
Мощностной стенд • R2Racing.ru • Диностенд Dyno Dynamics

Bisect means the horsepower and torque graphs should cross each other at 5250 rpm. This graph does not show that and he wanted to know why

Actually, bisect means to cut in half symmetrically.

I believe he was looking for the term 'intersect'.

Not bad, so what do the 5/6 speeds dyno? 320 or something

You are correct sir lol. Wrote that without thinking

may be this is because of that fact, as I wrote before, that it is difficult to find the point of downshifting for the tester even at 8-10 attempts. That's why the graphs themselves could be not quite right in this point of view, here I'd see the absolute numbers only. If the tester could find the exact position between pulling the gas and downshift moment - the absolute numbers would have been a bit higher and the graphs more precise. Just my thoughts. I'll ask for a whole photo of the graphs with RPMs.

But your comparing 390hp/407pd-ft to the crank, to 388hp to the wheels, 2hp from the rating from the factory, that's a big improvement man, nothing to feel down about lol.
