Difference in HP between Ram 5.7 and Durango 5.7?

[lipidboy]

Why is my 2015 5.7 rated at 395 horsepower but the 5.7 in the Durango is rated 370?

I believe the cam profile's are different. There also may be some slight differences in the intake manifold and the exhaust system.

same I think on HP for the 392 Charger, versus 6.4 in a truck is lower.

As far as Durango and RAM. It is the exhaust and the cooling. Also I believe there is some intake and airflow differences also.

As for the 392 charger and 6.4l HeavyDuty.

They are 2 completely different engines. The SRT 6.4l in the charger is duty cycled for a car. The BGE 6.4l in the HeavyDuty is duty cycled for a truck and actually has more in common with the 6.2l Hellcat than the SRT 6.4

Each application has a different set up. The engines are rated for each deal.

Heck the 5.7l in the HeavyDuty(which is now no longer available) was only 383 horsepower. Because it had to meet a different use cycle.
