How much power does a stock 2023 C8 Corvette make ?

In this video, I take my 2023 Corvette over to Boost Controlled Performance of Livonia Michigan to find out how much power it is putting down to the pavement.
The results were not what I expected...

I own 8 heavily modified late model American muscle cars. Over the last 4 years I’ve gotten quite an education on Dyno Ins and outs. Calibrations and software will cause a variety of differing results. One of the trickiest slights of hand I was shown is something called the “smoothing factor” it’s a great software tool to raise the WHP reading from a little to a lot. I got a first hand demonstration and my jaw dropped,when I saw how much it raised the Charts numbers. I’m not blowing smoke here my twin turbo Hellion was featured on R/T life’s channel pulling over 1000 WHP on race fuel.

2020 Z51 447.51 hp @ 6050 and 429.98 tq @ 5070 on DynoJet 4th gear. Stock 678 miles October 06 2020.

I'm no dyno expert, but when my 2022 C8 (completely stock non-Z51 with NPP exhaust) was tested at Paragon performance (Dynojet), the tech ran the runs in 4th gear. Best was measured at 447hp. Similar 30 degree day. I posted the video on my KZbin channel.

[@ParagonPerformance]

Your WHP seems lower than average. We do all our testing in 4th gear rather than 5th, you could try that to possibly see better results. We also did some testing with the AC on or OFF and there was a 5-12whp difference so that could also be your variable.

[@FindtheRightRoad]

Thanks for the advice. I appreciate it.

[@nyniceguy1318]

Paragon Performance: neither 4th or 5th gear are direct ratio 1:1. Is there a correction factor you apply to account for this?

[@ParagonPerformance]

@@nyniceguy1318 The power difference between 4th and 5th, from our testing, is single whp difference. We don't see the need to run out the car to 150mph on the dyno. No correction factor is applied.

[@clark-n-anitakalens7599]

With this DCT, I would expect no more than 12% powertrain loss. They best alternative test would be to mark off 1320 feet on a straight country road and record your MPH. It should be 120~121mph. if 114mph or less, you could simply have slightly less hp which happens with every model. If you're happy with the performance day to day, don't worry about 20hp. It happens all the time.

[@dayadam16]

Seems like the drivetrain numbers are correct on loss. Do you have to enter anything specific in dyno software for the numbers to be adjusted?

[@FindtheRightRoad]

I am not a dyno expert. So I do not know the answer to that question...

[@24theMoney]

This is the quietest dyno video ever.

[@FindtheRightRoad]

Yup. I decided not to use the loud audio. I did for my C6 video. :)

[@pjcornell9691]

Wow, that is a shame. Seems low. With Your C6 LS2 putting down 340 hp on that dyno You would think Your C8 LT2 would be at 440 horsepower. Very strange!

Starving of air

[@zrx338]

1) I would not worry about it...I am sure that your car is no different than all others. 2) If it is concerning, go try a different dyno because the result will vary based on the dyno and how its calibrated. Temps in the 40's should be making the best HP on the runs.

[@bigbluezo6]

Was the dyno in SAE or STD

[@ParagonPerformance]

Looks like STD.

[@rcauthen324]

Is the car broken in? I thought Chevy held back power until the car is fully broken in.

[@FindtheRightRoad]

The Revs are limited in the first 500 miles only....

[@rcauthen324]

@@FindtheRightRoad Oh Okay. My daughter just brought a 2023 C8 and only has 192 miles on it. Crazy, she had to get her car's transmission replaced two days after it was delivered to her.

[@kenstrain4366]

Seems like other folks are doing it in 4th gear.

[@mmettej]

Something's wrong with your C8 or the Dyno. There's at least 3 videos of 2022s making from ~430 to almost 450.

[@blakebiggs1065]

Make the runs in 4th gear. I predict at least 430 if you run it again.

[@bhvrdr]

Your numbers are just as much a factor of the dyno. Even one dynojet to another can be calibrated to ve off from each other as much as 20 percent. You can never truly estimate crank horsepower from wheel numbers. In other words your car may put down identical trap speeds to a car that dynod 450whp on another dyno.... because they're making the same actual power on the real roads (not rolling roads)

That a Dinosaurs not a DYNO
