FWD Mopar Dyno sheets!
This page is going to have a selection of dyno sheets that I have collected over the years from readers or other sources. In general it's pointless to compare dyno sheets from one dyno to another (Or even from the same dyno but on a different day!) as far as horsepower and torque goes but you can compare the curves to get an idea where a particular package starts and stops making power.
NOTE: There are two major types of dyno's- Chassis dyno's which read the horsepower to the wheels and Flywheel dyno's which of course gives you hp at the engines flywheel. Flywheel dyno's will always give a higher number because there is no parasitic losses from the transmission. The difference is about 15-20%.
Factory Dyno sheets (Flywheel)
1984 Naturally aspirated 2.2 vs. 1984 Turbocharged 2.2
1989 2.5 Turbo I
Notice the odd torque peak? The boost schedule was setup so the engine didn't exceed the maximum torque limit of the transaxle! In 1991 the ECU was revised and with the stouter transmission the same engine was now rated for 210 ft/lbs at 2400 rpm. (1989 was 180 ft/lbs at 2000 rpm)
1989 Boost schedule for 2.5 Turbo I
Horsepower and torque for Super 60 package vs. Stock Turbo II (unknown year) The torque number for the TII seems... off. They were well known to make 200-210 ft/lbs of torque. Perhaps they were using a tired engine as a baseline?

Wayne Hemingways 2.5l Spirit ES
268 hp and 372 ft/lbs of torque at 26 psi

Butch Nordstrom's '87 GLHS & '89 Daytona Shelby
Bone stock GLHS Charger- Notice the downward bump in the torque curve? The LM pulls back the boost here to prevent the engine from exceeding 175 ft/lbs of torque which was the rated limit of the 525 transaxle.
2.5 turbo intercooled makes a bit of torque at 19 psi eh?
