JDP Motorsports decided to find out the truth behind the videos popping up of the 2016 Chevrolet Camaro SS putting down more power than the C7 Corvette Stingray on the dyno. While both cars are powered by the LT1 V8 engine one does, in fact, make more power to the wheels than the other.
The dyno runs were performed on the same day, with the same dynamometer and the same fuel. Here are the results:
- C7 Corvette: 417.49 hp and 418.49 lb-ft
- 2016 Camaro: 421.48 hp and 427.80 lb-ft.
Both cars made more power on their second runs, but the Camaro initially made 4 more horsepower and climbed 6 more to 427.80 whereas the Corvette peaked at 418.49. Both of these cars were manual, and unlike the models equipped with the 8-speed automatic, they do not share the same transmission.
So now we’re left wondering if the six-speed manual in the Camaro SS transmits power more efficiently than that of the seven-speed unit found in the C7 Corvette. Though perhaps it’s something else. Share your thoughts in the comment section below.

if the oil temp was not within 5 degrees the HP could be off. the air temp also should be the same as you gain 1% in HP for every 10 degrees you lower the air temp to the engine
@ motorman
No wonder I feel my truck has a little more “Pep” on cool nights.
I agree with the previous comment by motorman. Also, while I don’t know the specs for the Camaro, I present the question: Are the gear oils in both the same Mobil 1? Presumption is they are, albeit, If not, RWT and RWHP will be different. Certainly having to turn one more set of gears and synchros in the Vette may be another cause. May be it is all cumulative. 8TY4SPD
Would be interesting to see the figures with both using the 8 speed Automatic.
+1 More Gear set of in/output shaft weight, (which also means polar moment of interia)
+ Engine oil/temp same?
+ Transmission oil/temp same?
+ Same ODO?
Kind of curious to see the outcome of a drag race between the two.
Corvette will still win in a drag race do to it being lighter. Overall the vette is about two tenths of a second quicker in a quarter mile. But what I think is the difference is when the camaro was being developed the camaro team designed different headers for the camaro than were being used on the vette. So that’s what I think is making the HP gain for the camaro.

he is right, look at specs
How many miles on each car? The Camaro was obviously pretty new. Their last test used a 2014 C7. Is this that same car? If so, the results are meaningless. Actually, testing only one of each car is meaningless anyway. Pick any other samples and hp could easily vary by 5 hp or more.
You all raise valid points, but most tests like these have varying factors as you described, and every experiment has its limitations. Hopefully we see more tests that are more accurate with less differentiating variables; we’ll keep an eye out for you.
My guess? Exhaust is a factor here. C7 may have more restrictive exhaust with it’s “menorah” shaped manifold where the Camaro makes use of a tri-y header (like the Z28). They are on paper rated the same, but what if the Camaro ran more of an exhaust manifold like its Gen 5 predecessor? Then the dyno might tell a different story.
Camaro clearly has a packaging advantage over the C7 in some aspects. Heck , even the cooling system seems more robust than C7.
