McClaren publicized numbers are often very close to wheel HP.

The transmission went into the rear in 97 so they had essentially 17 years to get it right in the C7. You can't shift 10% of the weight or approximately 350 lbs to the rear and expect perfect handling. I think that is a bit unfair. Porsche had snap oversteer issues for years.

@@Popdaddy88 Fine, but you can't believe the tests and think mid-engine succeeded when +200 HP equals the C7 Stingray's lap time. For the record I don't believe any of the hype, GM is flat out lying to sell cars. Like $59,000 claim that turned into $80-90,000 for a well equipped base model. Like the "3300 lb dry" claim that turned into to 3700 as driven. Or the "under 3 sec" claim that turned out to be 4 in every released video. Or the 0.7 seconds faster around the track than a C7, but after dynoing the same sample 200 HP higher than the C7. Or insisting the 39% front end doesn't understeer with two pro-drivers in major wrecks already. It's all careful weasle words designed to lie without getting them sued and that is bad news for real world performance. The most likely reality is the added weight and out of whack weight distribution results in slightly worse performance than the lighter, perfect 50/50 of the C7. And how could any other outcome be reasonably expected when messing with a 60 year developed chassis for no reason other than wives tales of mid engine superiority, when no mid-engine places in the top 50 leader boards using an objective measuring device like Dragy? GM can't afford that press so they didn't allow it. They shouldn't have panicked when C7 sales plunged from 31,000/year to 12,000. Every sports car is in similar decline, or worse. We are witnessing the opening of Automotive Armageddon--it is not a Corvette problem.

How about a car you don't dare jump start, but it kills the battery if you let it sit for more than a couple of days?

This has to be user error on MT's part, or a busted dyno. No way in hell does the BASE car make 600+hp at the crank. And if it does, then it's the slowest 600+hp car on the market. Yeah, that 2.8sec 0-60 and the 11.1sec 1/4 mile are impressive, no doubt. But look at the trap speeds. Cars with over 600hp don't trap 124mph, especially if they pull as hard from a dig as the C8 does. If it's really making that much horsepower, it should be trapping well into the 130s. Not only that, but literally every review of the C8 out there says that, for the first time in a LONG time, the Corvette is more chassis than engine. From MT, to Car and Driver, to Road & Track, to the more independent publications and individuals right here on YT, they ALL say the C8 needs more power now that it's got the proper layout to put it to the ground. And then there was the C8 vs C7 shootout, where both were equipped with their Z51 packs and the C8 was a second quicker around the same track. Over a full second quicker is phenomenal with the rated power figures, since the C8's 35hp "advantage" is cancelled out by its increase weight, so it shows the improvements in the handling and transmission more than anything. But if the C8 was actually rocking a 150+hp advantage, along with everything else, and was ONLY 1 second faster, that doesn't paint the C8 in a good light at all. So yeah, MT's numbers have to be bogus and I have no idea why they're sitting there speculating about it. What they should've done was taken the 'Vette to another dyno altogether, or at least tested another car with a known power rating for that particular dyno as a control. I feel like MT's just trolling for views and are putting up clickbait while trying to frame it as a big mystery to keep the hype train going.

@@bonosimic532 Oh, I have no doubt the engine puts out more power than it's rated for. Really, if you look at every performance car made in the last decade or so, I think you'd be hard pressed to find one that's NOT underrated from the factory. Everyone does it and most aren't even subtle about it anymore. BMW has been particularly ballsy about it. I think it was Car and Driver that had a Supra putting down more power at the wheels than it was rated for at the crank, and before that they had a BMW M5 that was doing the same. And I like that. It's the baker's dozen, the 13th treat in what's supposed to be a 12 pack. What I don't like his how MT is presenting it. It's not a ringer car, the C8 Stingray doesn't make 650hp from the factory, their dyno is clearly on the fritz, but here they are talking about how the SAE's tests produce lower numbers by nature and how they've been wracking their brains trying to make sense of the data. There's nothing to make sense of. The data is wrong either due to human error at some stage or faulty equipment, likely both. But instead of doing other tests with different equipment, they chose to act out Einstein's definition of insanity by doing the same thing over and over and expecting different results. It's honestly baffling.

@jayrife5949 4 жыл бұрын

Right out of the manual. All of the following factors can influence the power measured by a chassis dynamometer: 1. Tire compound, pressure and temperature. 2. Engine, transmission and differential temperatures. 3. Lubricant types. 4. Method of vehicle restraint (downward pressure will waste power). 5. Type of testing performed: fast decelerating sweeps will generate the highest values, steady state tests will generate intermediate values, and fast accelerating sweeps will generate the lowest values, due to the internal power requirements of the engine and drive-train in the vehicle under test. 6. Atmospheric condition corrections to different “standard” conditions. 7. Operator driving differences (can be very significant!). 8. Data acquisition options, particularly smoothing/averaging and clipping functions. mustangdyne.com/_wss/clients/205/assets/c205_resources/20170606154755541.75

@GoogleEqualsEvil 4 жыл бұрын

Exactly. Chassis Dynos are for TUNING, NOT for accurately measuring Power / Torque. ONLY a Flywheel (Crankshaft) Dyno can accurately measure engine output (Power / Torque). Which is what the SAE protocol uses. Plus, the SAE testing protocol is a detailed, standardized testing protocol designed by actual ENGINEERS, not a random operator running a Chassis Dyno just doing random pulls.

I'm a GM fan boy myself. But I know it wouldn't be the first time they under rated their engines. I don't remember the exact numbers but the Buick Grand National is one of them. My dad worked for GM for 32 years. And the 283 Power pack was another one. How about 410 HP from a B body at the Janesville assembly plant, He told me the engineers didn't even understand why it was producing the numbers themselves. My thoughts would pure geometry. Even a cast iron crankshaft at a 3 inch stroke can run all day at 8200 RPM. And He said they had to actually tackle valve float to get it if memory serves me correct. Only thing is I don't know is if it was a Carter carb engine or the Rochester fuelie. This was long before the Quadrajet in 65. One article I read was they did it to keep the insurance companies at bay along with government regulators. A little fuel for thought. Thanks for your time.

Why is it surprising that an engine can make 90hp/L in 2020. Cmon guys. Underrated horsepower for insurance, and to give room for the other models in the range. I personally felt it was underrated on the release day. That it was at least 80-100hp more at the crank.
