Never bothered to pause it, but since their numbers were a little higher then all the rest, I assumed it was uncorrected, hence my post. But depending on the weather, uncorrected can at times actually be lower. SAE with a smoothing of 5 is what I always make sure my dyno shop uses as it gives the best numbers for comparison and consistency.

Right. I was just pointing out the difference in correction factor used is all. Nothing earth shattering on my part, just pointing it for others who may raise an eyebrow due to the differences. Obviously you know what's up.

It's also been stated that it was getting spark knock and pulling almost 2 degrees of timing so they splash it with some race gas.

Yeah, my guess is the car didn't have 93 in it, it pulled 1.8*, which isn't a lot, and would fit a lower octane fuel being used. Or, possibly a bad batch of non top tier fuel...

I am betting it mostly had 87 in it. Most factory tunes are meant for 91 octane, not 93. Too many markets do not have 93 available. In my Z I had a group of maps for 91, 93 and 100 octane. I would mix race with super when needed. A lot of dealers fill up their cars with crap gas.

Correct. It's well known and documented (it's a straightforward formula) that an STD correction factor results in ~4% higher readings than SAE. So roughly 16rwhp is from the correction factor alone. The other 2rwhp or so probably from the octane difference.

What makes you think that they would use two different direction factors between pulls? FYI they don't do that. Also its been said the only difference was a spash of race gas to help with spark knock. What we don't know is if it had it because of fuel (87,89,91,93) or it was just a warm engine that pulled 2 degrees. I will say though that 417 is a fluke number and can't be repeated. If it did then I'd say its a very generous dyno or a ringer and you can't deny that.

Did you not watch the video? It's clear that the correction factor used on the video was STD. It says it on the screen just before it zooms in. Very simple stuff here people lol

Yes.

That would put the weight of his SS around 3750. What options are on that 1ss?

Not sure about Gen 6 SS, but Gen 5 SS has two trim levels for fuel. A lot of discussion about this, here is a link. What octane fuel does the factory put in?

Pretty common on these new cars, but this (gen 5) seems to be more effected by it then most other cars. Interesting...if the gen 6 has this set up the same way, it could surely come into play on a dyno run made right after a fuel swap.
