So even though the v6 will be faster than those ancient z28's I bet those old cars would feel faster.

On the debate of horsepower — "horsepower" is just a marketing term to express the more general term "power" which we normally use watts to measure. Watts are usually used in the context of electrical power, but it's proper to use watts when talking about mechanical power, electrical power, or any form of power.
"The metric horsepower of 75 kgf-m per second is approximately equivalent to 735.5 watts or 98.6% of an imperial mechanical horsepower." (Wikipedia) Power (in in joules/second or "watts") = work / time Work (in joules) = force x displacement (in meters) over which force is applied In other words: Engine power should technically be measured in watts, not horsepower. Horsepower is a legacy term for an approximation of how much power (in watts) a horse would make — eg: 735.5 watts. Horsepower (watts) is a measure of force applied over a distance, divided by the amount of time it takes to travel that distance. Distance / time is another way of saying speed, so really, horsepower is the force with which the engine sends you forward x speed. Horsepower = force to move forward x speed —therefore— Horsepower / force to move forward = speed. Force is mass x acceleration. So if you have less HP, but require less force to move forward due to lighter mass, you can still achieve higher speeds. Trucks have a ton of horsepower and torque. But because of their big mass, they don't set speed records. Unlike horsepower, the explanation of torque is a ton simpler. It's just "twisting force." It's measured in newton-meters. It's force x the distance from the center of what is being twisted. Force is measured in newtons, distance is in meters, so thats how newton-meters is derived. Therefore, if we're discussing whether torque or horsepower is more important: This isn't really an apples to apples comparison. Horsepower is the measure of the speed and forward force at a moment in time, and torque is a measure of how herd the engine is applying twisting force to bring you up to speed. Two different things. Once the torque peaks out, the engine continues to build horsepower until it reaches its peak, but at a much less sharp rate. This is why in a torque curve vs horsepower curve plot, the torque typically peaks first: This is a really long-winded way of saying the below statement is accurate: “Torque is what gets you to the speed you want quickly; horsepower is what keeps you there.” Last edited by RenegadeXR; 10-06-2015 at 11:56 PM. |

Went to that shops website to see what kind of dyno they used. They had a pic of a 2015 Mustang that they baselined with the printout and got 366 WHP. Looks like the SS has a big advantage there!

Bottom line, no engine is underrated anymore. These engines have verified power output within 1%. The LT1 makes 20-25 more HP and 60 or so torque above the Gen 2 Coyote. The 6th Gen SS is now not only more powerful than its pony GT rival but is lighter as well with and in some cases has better overall gearing. I don't even think it will be a drivers race like previous years.

Here's a thought, make a thread where you guys can circlejerk in one spot about him and stop crapping up every thread on the forums, eh? Back on topic: Love the videos, can't wait to finally see them in person on the 24th.

Just remember that chassis dunks are not accurate and comparing chassis dump numbers to SAE engine dynos is no way to figure out drivetrain loss. Every chassis dyno has so many variables from heat, humidity, air pressure, plus the equipment itself that makes it impossible to accurate/real numbers. The chassis dyno is good to see the power curves, get an estimate of overall power and use for tuning.
On a race track the location of the power curve is very important, the LT1 in the gen4 made very low end torque which was foR 0-60 and that's it, it fell on its face after 70-80. On the track the engine spends it time over 3,500rpms up to redline which is why a high torque curve is important for track cars.

HP is the rate the force can be applied. Accelerating from zero or up a hill, torque matters (ie 1970 Biuck Stage 1) If you are in motion, power

No matter whether you consider torque or HP the greatest attribute, this car is definitely fast for a baseline V8. Reports so far, make it a real contender in a race against the current Corvette and puts the C6 base Corvettes on notice...you're not the fastest sporty car on the street any more! I'm praying they fixed the axle hop so prevalent in the 5th Gen 6 speeds.

For comparison, the Scat Pack Challenger dynos at around 430rwhp. Even with its added weight, I'll have to line up my new Camaro with my new Charger Scat Pack and see which one wins, and swap drivers too, to see if its consistent.
Note that my Camaro will be an M6 while the Charger Scat Pack was ordered with an A8. Around corners, there's no question the Camaro will win, but... is that extra 25 horsepower enough to make up for the added weight? (also, which one will be delivered first? TPW of 10/19 for the Camaro and a production week of 11/9, but it seems that the Charger has quicker delivery times?)

Both watts and horsepower are a way to measure and compare power like inches and meters are a way of measuring and comparing length.
