I KNOW the numbers are bogus...explain this...

nissans rating
480 hp @ 6,800 rpm... 430 lb-ft torque @ 3,200 - 5,200 rpm.
59.2 kilogram meter = 428.1944188307 pound foot

isn't it a heck of a coincidence that the two dyno numbers match nissans ratings almost perfectly? 482 vs 480 HP and 428 vs 430 ft lb ...hmmmmmm

also at 5250 HP = Torque, the lines cross...
HP ~ 465 or so...
T ~ at peak 426 or so...
they don't match...hmmmmmmm

but wait, they HAVE to match HP = rpm/5250 x T...at 5250, HP = T...period...

they also state max torque of 430 from 3200 to 5200
peak T is only 4700 to 5200, well shy of the claimed

oh yea, claimed HP peak is 6800, this is ~6100...

it's off everywhere...

rpm.....dyno T......dyno HP.....calculated HP
3000....130.............60...............74
4000....330............275.............251
5000....428............440.............408
6000....380............480.............434


the ratio window (4.660) should be 1.248 x 3.7 ~ 4.618...4th gear run...

dyno speed at T peak 78 mph/5130 rpm...but calculated speed using the ratios is 91
dyno speed at HP peak 92 mph/6115 rpm...calculated is 108...

this, and the HP/T mismatch at 5250 screams rigged...
