And if it had the "right gearing" it probably wouldn't be street legal because of the EPA.... Everyone seems to not figure out that it's the most powerful NA V8 ever... That comes at a fuel efficiency cost. Can't just throw a ton of short gears in there to average 8mpg as much as we'd love it.

Remember, this drivetrain does not have the "typical" driveshaft and u-joints to account for power loss, what you're seeing here reflects a lot less net loss due to the stiffer short sidewall of the tire and nothing between the engine and transmission to absorb rotating losses.

2018 C7 of Year Finalist
Love all the bench racers here. Showing absolute disbelief over a 30whp difference between a Mustang Dyno and a Dynojet. This isn't uncommon at all. My C7 read differently on every kind of dyno there was. Always in the same general area, but never expect the same numbers. Mustang dyno's read lower, dynojets read a bit higher. This is common knowlegde in the modifying community.
No, Fabspeed did not spoof the settings for it to read a higher number. They don't care what the stock dyno number is. They are using it to show any potential power gains with their newly developed exhaust system they are R&D'ing. The fact that the baseline run was high is literally meaningless to them so they have 0 reason to engineer a "hero run". To be honest, its probably in their best interest to show lower baseline runs, so they can show their exhaust posting up higher numbers. Not the other way around.
At the end of the day, a dyno is not an exact measurement. It will generate different numbers due to all kinds of different reasons. It's a tool to see power improvements after mods and get a general sense for performance. Cars are going to show a range of whp readings based on many factors so don't read too much into this 30whp difference.

I bet you at least 60% of the potential customers actually do care about the stock power numbers.
So this is a naturally aspirated 670CHP SAE certified car. Apparently fabspeed is already at 41HP gain (according to some preliminary math) and apparently, he is just getting started so since apparently, he also likes to be the first on many things so how about Fabspeed, first in the world to obtain 60 HP gains on cat deletes alone. Add few little things here and there like let's say headers and voila' 100HP on a naturally aspirated engine just like that....

So many ignorant folks… this is dyno trickery to get clicks. The LT6s are SAE certified. The car has no 1:1 gear so it must be dryno’d in 5th which will falsely show more power unless the dyno is adjusted for it.

I would agree with you except that mr fab is in his own thread claiming GM is underrating the power based on these dyno results. Someone who is claiming to be an expert/specialist not understanding what sae certification means would be a little off-putting if I were a customer

So why on earth did Phenoms car trap so low in the 1/2 mile? I timed his car 65-150 and it was 13.0~ seconds. My stock C6 ZR1 does it a full two seconds faster, with a passenger, 3rd gear start. Is it really all down to gearing and aero???
Man GM really needed to get with Tremec for bespoke gearing. How can you use the 458 for inspiration and NOT include the bang bang bang bang short gearing?
This incredible piece of machinery would've been even more incredible if it didn't use the base C8 gearing! Having 3 gears never used is crazy. The whole idea of a high revving flat plane crank V8 is to keep it spinning high.

Just like that "oops" inflated Stingray dyno one of the mags posted.

These dyno numbers are all over the map. Let me know when they put it on a true electric dyno corrected for temperature and barometric pressure.

It doesn't have a straight pipe.... the entire video is the car being dyno'd OEM stock, then a walk-around of Fabspeed's shop, then a teaser clip at the end with sport cats. That's it.

25 for the intake and 19 for the most expensive extreme corsas.
But then again, I have a feeling you already knew that and yet.....
At least next time post the link..? it adds a bit of you know what...
