DQ, Whats the difference between a Mustang dyno and a dynojet?

Unit 5302 · 08-21-2001, 09:58 PM

A proper tune on a non load bearing equipped dynojet should include a max hp run, and an all gear run.

When this is done different loads are placed on the engine, significant enough to show a loss in hp associated with pinging, or unmask the supposed masked pinging.

For example, a 3rd gear dyno pull on it's own should be identical to the 3rd gear run in the all gear, and the car should not detonate or ping when in 4th gear.

How in depth is the EPA load information? The difference in any given 1987-1993 model year 5.0 between stripped 5spd coupe, and auto aod vert could easily be 300 lbs. A difference of 10%

If a person has problems with detonating and pinging and continues to blow head gaskets, maybe they should think about a different tuner, not a different dyno.

Also, if it REALLY bothers you that much, you can order the load bearing attachment, the air fuel ratio monitor, and the rpm pickup for the Dynojet for a grand total of $4550, or the load bearing attachment for $1500 stand alone.

I've seen the results of a Mustang Dyno tune. 330rwhp and a 107mph trap

in a lightened 89 Saleen 5spd.
