If the 650 horsepower figure is accurate, GM has accomplished the highest producing horsepower, normally aspirated 8-cylinder engine in the history of the world. LOL
LOL Guess you dont know much about chevy !! ZZ572/720R
Crate motor from Chevy ! 727HP , not even fuel injected !!
If road and track did their nonsense negative good but not great...motor trend just did its BS dyno test to balance the PR nightmare from R & T...
click click click...read all about it from both auto magazines seems more like whats going on..
disappointing state of affairs when journalistic integrity is out the window on both sides.
nobody is getting560 hp out of a naturally aspirated motor...with out a turbo to dial up and down...its a dyno twist of the dial...or a dramatic change in correction factor....
id love this hp rating to be real but its click bait ..
Mustang Dynos use an Eddy Current Brake to replicate the ACTUAL WEIGHT and coefficient of drag whatever car YOU TELL IT is on the Dyno. It also asks for road hp at 55 or 60mph. I forget.
Tune time performance has had an awd mustang dyno for about 14yrs. I've operated it. Installed it. Relocated it etc... it's great for driveability problems as well. Nothing like the old school static roller dynojets.. the better dynojets use a brake now as well but they are way more money (like an awd mustang dyno).
Maniacs screwed up the inputs and viola. 60000hp and tq... idiots.
it's not "reading lower"... it's reading more ACCURATELY

Can you explain how the weight and coefficient of drag on a car influences how much power the engine makes (either at the crank or at the rear wheel)? Are you talking about 1/4 mile prediction? I agree, MT had idiots conducting the dyno test on the C8.

.
The 812 Superfast motor has 788 HP and is naturally aspirated...
Your post is click bait because its so ignorant....
Not so much fake news as much as click bait and bad reporting. The numbers are wonky and that should have been examined more thoroughly, whether it's a screwy dyno or GM screwing with the public with a ringer C8.

It actually sounds like the dyno was stuck in the awd coefficient mode when the 2wd mode was selected there for accounting for the 3 or 4 sets of front rollers that obviously weren't spinning... Im 95% sure that's what happened ( that and the 19500 miles I have put on my mustang dyno) I would bet our c8 will make about 410 to 415 wheel ... I understand it's not click bait ...

Motor Trend needs to put that same C8 on a different dyno.
Of course it's what they should do. It's not what they're going to do, though. They even told us what they're going to do: put another C8 on the same dyno in the coming months. I suspect that by then, the dyno operator will have figured out his error and the resulting numbers will be quite a bit lower. Just imagine the resulting article? "Proof that GM gave us a pre-production ringer!"
Oh no, now you've gone and done it. If they catch wind of this they will try to tie it to the WH.
I suppose someone didn't really know how to set up the Mustang dyno or read the numbers. When reading numbers more accurately than the dynojet I suppose it means, more accurate = lower values.
