LS9 Power & Torque Curves & Data
After a lot of searching and data averaging I was able to plot out the Hp & Torque curves you see below. I hope this helps answer some of you that were interested in this information.
You will notice the torque in blue. Also there is over 500 ft- lbf from 2200 to 6600 erpm. That is a very broad range and the shape of the curve is pretty flat which is why the ZR1 starts out so strong and pulls for ever.
Also on the graph are vertical black lines the represent the erpm (Engine speed) that you will be shifting from the lower gear to the higher gear. For example the 1-2 shift if you shift out of first at 6600 erpm, you will then be at 4,640 erpm when you engage 2nd gear, and so forth.
If you have any questions just let me know.
I will be doing a comparison of the LS9 - LS7 - LS3 next so we all can see the differences.
Remember torque is key to acceleration and produces the thrust force the tires transmit to the pavement. Power is the work per unit time and what ultimately determines the maximum speed (Terminal velocity) of the vehicle. As always the more the better and you can never have too much of either.
