R1600Turbo

Anyone have one? Particularly with a 5-Speed?

Trying to get an idea of the factory torque curve.

Thanks!

Thanks. What's with the lower torque number? Are the real world numbers that different from what GM advertised? I would have expected the torque number to be higher than the power number.

gm is at crank with no accesories. be thankful that there that high.

That's not what I was getting at. I'm wondering why GM rates the torque higher (155) than the HP (145) yet on his dyno the outcome was the opposite. (HP higher than torque)

Race car. As mention earlier the engines are rated at the crank. So you lose energy through the drivetrain and accesories.

power (the rate of doing WORK) is dependent on torque and rpm.
torque and rpm are the measured quantities of engine output.
