Whats the avg, highest and lowest: Dyno Jet or Mustang dyno ( I know the Mustang will read about 15% less than the Dyno Jet).

007 said:Best I saw was an 04 auto dyno 217hp on a dynojet - that was really high. They should get about 208hp.
Note that gears will knock a few hp off the dyno measurement.
Toms_2003_Stang said:But they multiply torque which increases your SOTP so it basically a trade off.
hotmustang331 said:Tom, gears dont REALLY decrease RWHP, but the dyno shows this due to its load or something. If you dyno in 3rd it will usualy dyno about 10RWHP lower...almost teh same thing as puuting in 4.10s and dynoing in 4th. Your still putting the power to the ground, but its not reading all of it.
007 said:Afraid not. Autos put less power to the wheels, fact. Torque is effectively the "power" (in fact, energy) per rev. If the hp is lower, the tq at the same rpm is lower too.
Lower rwhp and fewer gears makes the stock auto slower than the 5 speed (assuming the 5 speed driver can drive).
A shift kit, gears, and a high stall really make up for the power loss.

Toms_2003_Stang said:So what would be a good stall speed for a DD?
ponysarepretty said:Nope hp is the energy or power created at that rev point, there are several ways of measuring power, we use horsepower, germans use ps, british use bhp some places use kW which is the most apt. The torque is a force, it is not the power, as seen it is measured in the units lb/ft or Nm. Horsepower is a function of torque, not the other way round.
