First C8 Z06 dyno numbers...is Chevy lying?

- The first C8 Corvette Z06 has hit the dyno and the results are shocking! Speed Phenom took his 2023 Z06 to Dallas performance in Dallas Texas after a nice break in period to see what kind of number the Z06 puts down at the tires. Honestly...it's more than I was expecting

I just dyno'ed my bone stock "600" crank hp GTR, and it put down 567awhp on a dynojet. I uploaded the video about a month ago. So 567/600=.945 would be equivalent to this C8 doing 670x.945=633whp not even accounting for the AWD drivetrain loss of the GTR. Mine came with factory CCBs and light Nismo rims which helps out. I feel these C8 dyno numbers are on the high-end of what's expected, but I think Nissan is sandbagging the hp rating on GTRs. Even if I assumed a conservative 15% drivetrain loss for AWD, it would still be 652hp at the crank.
Make the title pop more with some capitalization and the thumb needs the text and face much bigger and add new zo6 to the thumb maybe? Good vid
Thanks 😁
I actually reached out to the owner of Paradigm Automotive & Performance regarding the numbers it put down to get a professional opinion, his exact words were "Avg drive train loss for 2wd vehicles is 10-15% and for awd 20-25%. 610 whp would equate to approximately 670-700 crank. Ballpark."
Now there several people out there that have and are staunchly disagreeing with that assessment but more often then not, you'll find... that they are in fact an owner of a previous generation Corvette. Go figure. 🤣🤣🤣
😂
No Chevy isn't lying about the power output. It falls exactly where it should with a DTC transmission. The C8 Stingray saw the exact 9% delta in rwhp from the GM rated crank HP.
So not difficult to confirm. The 670 rated C8 Z06 put down 610 in Austin's dyno run. The C8 Stingray rated at 495 put down 449 (after 500 miles).
So it's spot on the nose.
Street Speed 717's just made 640WHP at Fabspeeds shop
I saw that video. I wish they would have mentioned if it was SAE or standard
@@automotiveantics True, but at least between the two we can definitely see an underrated number by GM.
@@BSTDC8 for sure
@@automotiveantics I just went back and watched the video again. It was SAE:1
@@BSTDC8 Not true. Chevy measures these engines to SAE certified standards. It cannot be underrated. Many people dont really understand this or how dynos work. To get an engine SAE certified an independent party randomly selects engines off the production line to dyno them. They must result within 2% of the advertised hp rating for the car. As far as chassis dynos go, they should only be used to show before and after results. They are not good at telling you how much is lost between the engine and the wheels. This is a pretty common misconception.
Can't wait for next year's ZR1..... TWIN TURBOCHARGED Z06 MOTOR SAID TO PRODUCE A MINIMUM OF 850 HORSEPOWER AND PERHAPS 1000HORSEPOWER. SOUNDS LIKE 0-60 IN UNDER 2 SECONDS....IF THEY CAN HOOK IT UP, PERHAPS A 395 X 23 INCH REAR TIRE?
I'm disappointed in the Torque
Flat planes usually run the rpm more but lower on torque. It's no slouch as can see on #s it shitz and gets
High torque isn't as important as you think. It's the reason why Chevy kept getting spanked by Porsche. Unable to put the power down properly. The C8 Z06 spanked the hell out of the 911 GT3 turbo. It's the reason Japanese motorcycles are so fast . High hp lower torque is the best recipe for dominant performance.
Why are you disappointed in the torque? This engine has huge torque considering it’s displacement. My C5 ZO6 for example puts down ~370 ft-lbs from 5.7L, this thing is destroying that number with 420 ft-lbs from 5.5L. This new Z is laying down torque similar to the C6 ZO6’s 7L LS7!
It’s a monster that runs mid 10’s. Let that sink in. Then consider it’s got real downforce and massive grip, it’s going to shake up some racetracks too.
@@g4do 911 GT3 Turbo?!? Did Porsche release a new car I wasn’t aware of? 😂
Chevy don't lie because to work correctly your dyno machine absorb power and torque , so the 9% difference is normal with dyno.
True but normally there's also a 10%-15% drive train lose which would not including what the dyno absorbs. But that number could be lower being a mid engine car
@@automotiveantics It's just because your dyno wasn't programmed correctly because the output pinion engine's power is always different from the power received at the wheels, a well-programmed dyno must always apply 9% delta of power and torque to have a correct final result.All automotive manufacturers apply the same 9% delta.
did they release the adjustments they made? That could change everything and you shouldn't trust anyone if they aren't willing to release that info.
What adjustments might you be referring to?
I think he’s referring to SAE corrections. And the answer is yes. These numbers are SAE corrected. No proper tuning adjustments were or can be made with the EBCM in the C8 yet. Some are sending out “breaking news the C8 can be tuned” but proof of this is TBD. Apparently Trifecta Performance Inc got the green light from GM to native tune the EBCM. Every other tuner shop still has to use standalone systems.
Correction…it wasn’t a “green light”. They cracked the coding to get into the tune. I just reread the article sober.
wow
Right!
As to reliability, this is the same engine that has been in the race car for 4 years?? I think so. Seems to hold up.
Not really a good comparison considering race teams have extreme maintenance service intervals. I wouldn't be surprised if it gets rebuilt or at the very least torn down and inspected after each event lol. They don't just go out and race them and change the oil and spark plugs every so often 🤣😅
@@nickadkins7765 The stress of endurance racing should have exposed any weaknesses and flaws. But i guess you know better. Thanks for your input.
@@johnultimate1161 sure they can improve things for RACING but they aren't daily driving those cars. The video is referring to long term longevity for the average consumer, not longevity on a racecar that only drives on a race track. 2 completely different things. No need to be a sarcastic prick about it.
@@nickadkins7765 You led the way on that one.
@@nickadkins7765 you really went at the dude being a sarcastic prick and started crying when he did it back. imagine being that dumb
Or they messed with the stack temp and made a happy dyno total horse shit
I don't think it will lose any power without the carbon fiber wheels...I know with motorcycles, when we put 240 and 300 wide tire kits on motorcycles, the peak horsepower numbers stay the same, it just accelerate slower/takes longer to get to the horsepower peak, so, the Z06 with regular wheels may accelerate slower on the dyno but should still reach the same horsepower peak...maybe..... lol
These engines are SAE certified. They cannot be underrated. People unfortunately arent very knowledgeable on these things which is how dumb internet rumors like the C8 Z06 is underrated get spread. Just review what goes into getting an engine SAE certified, they've been doing it since the C6 Z06.
Didn't some of the C6 ZO6' make 460 rwhp? Maybe that was just a generous dyno you think?
@@Bamabrute85 Yes, dynos are NOT good for telling you losses between the engine and wheels since ALL dynos will give you a different reading. They should only be used to tell you before and after results. Unfortunately many people do not understand this.
