1le dyno numbers

went looking around the corvette forums to see what stock zo6 dyno numbers were as i plan to mod mine to get similar numbers. i noticed that the drive train loss is around 12%. Do you guys think that with the z06 transmission and 391 gears we will see the same numbers as an SS or higher.



Vote and post a best guess number

I'd say about the same as SS.

I could be wrong but the corvette drive train loss is that low because of how the transmission is mounted directly to the rear and the use of a torque tube while the Camaro has the traditional engine mounted tranny and drive-shaft (im new to Gen5 camaro's so I could be wrong.)

Who knows. Totally different drivetrain setups.

I would think a little more than a 2010 SS and about the same as a 2013 SS.

The small rwhp advantage that lighter wheels/electric PS give would be tamed by taller gear IMO. Nothing that would make it better on the dyno. Maybe some for the free flowing exhaust, but that can be ordered on any SS.

Perhaps this is an invalid question since the gearing and weight isn't the same ....

Quote:
4. Q: Does the dyno measure wheel horsepower or engine horsepower?

4. A: The dyno measures wheel horsepower. Torque is a slightly different story, however. Since gearing has a direct bearing on torque and 1st gear would obviously generate a great deal more torque than 5th gear at the wheels, to return a useable number, the dyno actually gives you engine torque as measured at the wheels. It does this by factoring the engine rpm into the equation and negating the effect of the different gears. If this hurts you to think about it, then stop - just trust me.

..

There are also a few more things to consider when choosing the best type of dyno for your needs. A Dynojet (inertia-type) dyno places an identical load on every vehicle. The only difference in load to the vehicles' engines will be from different gearing and/or if vehicles are tested in different gears. Therefore, as long as similar vehicles are tested in the same gear, comparisons with the dyno results are perfectly valid.

The load that a load-type dyno places on a vehicle varies depending on the parameters that the dyno operator enters into the computer, namely the vehicle weight. Some shops with load dynos weigh each vehicle and use that weight, others look up the weight on a chart. There is an inherent issue with these methods that must be considered if one is to use a load-type dyno to compare results between vehicles. For example, if two Mustangs have the same engine and drivetrain, but one weighs 3600 lb. and the other has been stripped for racing and weighs only 2900 lb., which method should be used? If the actual vehicle weights are used, one engine will be loaded significantly higher than the other. If the same weight is used for both vehicles, the load placed on the engines will be the same, but which weight should one use? One may even argue that the actual vehicle weight must be used in order to duplicate real-world driving conditions, but that would inevitably return different results in cases like the one in the above example, even though the two vehicles have the same powertrain. One could therefore change a vehicle's horsepower output by changing its weight.
