Great Vid, Thank you.

If they had been able to play that at the GT8 Launch they would have sold a lot more SSII cars I think

Nothing wrong with that gearbox!!!!!

Rated power: 446 hp, measured power on power test: 410 hp

Why is that?

Really only 10 seconds quicker than the N400?

I dont know why, but its a bit worrying

Good effort!! Wish they'd do it with a V12VS SS...... I'm sure it would be sub 7'30"...

Why?

The engines will never all be identical in terms of output. So without anything else being different, there will be variance. Manufacturing tolerances.

Then you have the way they are measured. Engine dyno or chassis dyno? Very different ways of measuring. One involves hefty use of estimates on losses. One doesn't. Even the same type of dyno can give different results, for the same reasons different engines can.

Also, the temperatures during measuremnt, age of engine, mileage at various revs etc etc etc. Many can allegedly be corrected for. But I'm not convinced they can accurately.

36hp is an 8% shift. Very easy to see how that might be a common level of variation. (btw, were they both using the same units? Mags/articles often don't...bhp/PS/etc).

Haven't watched the vid yet - but just to note that manuf ratings are usually with the engine on the bench, and I expect this was measured at the wheels.

They have: 7:52. Limited by traction I expect. No doubt the aero would help with that. Would ask for a GT12 hot lap instead.
