Hey Guys I purchased a 2002 Volvo with a Detroit last week, and ofcourse thanks to this valuable forum before I bought it, I had a dyno test
run and here were the results...

443 Hp @ 1520, Engine Load 100%, 1520Ft Torque, Pre EGR Boost 29PSI

Coolant Temp 194F, Oil Pressure 50 PSI, CCP In H20 1.4

The engine is rated at 435/470 Hp. The Tech seemed surprised at the readings. He said the Hp numbers were really strong for this engine.. I was wondering what some of the numbers mean???? are the Horsepower ratings to the wheels?? and if so, what percent drop do you expect from the engine to the wheels......Thanks for your help

Chris

Yes, that HP number is really good.

It shows that the engine is sealing in the power really well, and isn't leaking past the rings. It also shows that you have a good driveline that doesn't rob power.

Yes the HP rating is at the wheels.

What kind of transmission and rear gear do you have?

Yeah... Thanks for the reply The transmission is a 10 speed Eaton autoshift. The rear gear is 3.55 and the engine has 635,000 miles on it.
