The all-new mid-engine 2020 Chevrolet Corvette is here! Full serial production is under way, and deliveries are now heading out to dealers. Unsurprisingly, one owner was so eager to unleash the Corvette C8 they decided to bring their new coupe straight from the lot to the dyno to see what she’ll do.
Recently posted to social media by Carlyle Racing, the model in question is a Coupe covered in optional Sebring Orange Tintcoat paint and capped with Bright Red-painted brake calipers. Critically, this particular 2020 Chevrolet Corvette doesn’t have the optional Z51 Performance Package, as evidenced by lack of the Z51-specific front splitter and rear spoiler. It also sounds like the optional factory performance exhaust system was not equipped.
Carlyle Racing actually posted two videos of the new 2020 Chevrolet Corvette spinning the rollers, with two separate runs documented.
In the video description for the second run, the post reads: “440/408 with 20 miles on the car,” indicating that this 2020 Chevrolet Corvette made 440 horsepower and 408 pound-feet of torque. Chevy advertises output at 490 horsepower at 6,450 rpm and 465 pound-feet of torque at 5,150 rpm without the performance exhaust system. To note, all 2020 Chevrolet Corvette models are equipped with the naturally aspirated 6.2L LT2 V8 engine.
It’s also worth noting that with just 20 miles on the clock, this C8 Corvette is well behind the recommended break-in period. As we’ve covered before, Corvette Chief Engineer Tadge Juechter has previously outlined the C8’s 500-mile break-in period, highlighting that max torque is reduced roughly 25 to 30 percent in first and second gears, while engine speed and redline are not limited.
“So the torque reduction limits the worse of potential break-in wear, but it is not a panacea,” Juechter said. “We will still be asking customers to stay well off max torque and speed for the first 500 miles. We know it’s hard to stay patient when such performance is available, but it will pay off in the long run.”

Quoting dyno numbers and manufacturers numbers without explaining wheel vs engine HP and also various dyno models and calibrations is a disservice to readers.
Given the dyno results I'd bet it's making a decent amount over manufacturer claims on cold runs like how the C7 Z06 was rated 650 when hot
I'd wager GMA readers know all about wheel vs engine hp and possible dyno model discrepancies
Doubt it, the commenters maybe. Especially when both numbers were compared side by side in the article as to suggest the disparity in the numbers is also due to 1st and 2nd gear break in limitations where as pulls are generally done in ratio closer to 1:1 ratio so maybe 6th. If they are in say 4th and the dyno converting for the ratio to output then you'll further have calculation loss and inaccuracies
Weird that constructive criticism is met with a speed bump. I know the C8 can raise its nose to such things, doesn't mean you should ;)
I agree with you Johnathan! But first and foremost.....imho, what kind of a DA would take a ($60,000?) brand new 2020 Vette, with a whopping 20 miles on the clock, and Dyno the damn thing?! Obviously someone with more money than sense.....and no appreciation or respect for the mechanicals! Can’t wait for all the, “it’s a free country” comments!
440/0.85 517 by my math
Driveline loss will be less than 15% on that car. Looks like it's right at the rated number.
Waste of a dyno run if you ask me. Shouldn't be any limitations period! To start with true hp and torque at the flywheel would be nice! Helpful dyno data would be start with no limitations, and get one good base line run for rwhp and torque at max rpm. Now let the tuning begin.
What does this prove.............waste of time.
Why would one do a test knowing there is software in the stream that will/may effect the outcome. Regardless of if they were taking a "part" of a different conversation as gospel from the Chief Engineer explaining "why" the restrictions were needed to complete the "break-in" cycle to ensure max performance...
Is being first that important to override accuracy to introduce data could or known to be in error? Sorry guys, old school and don't believe in that currently accepted being first overrides accurate. But in their defense they do clearly state it only had 20 miles on it and explain the possibly variables to be considered.
I am a little OCD when it comes to break-in periods and have had arguments with service personnel of dealerships (not Corvettes) balking when I demanded a oil change between 500-1500 miles during that period...
Having broken in lawnmowers to 500K Rolls-Royce engines, it matters when it comes to the process.
