Ranger Diesel Dyno with pump mods

Dyno’d the Ranger tonight for the fun of it. I didn’t have an EGT gauge to share temps but the numbers show that the sweet spot is 1 turn on the pump. Just wanted to share with you all so you could see the sweet spot and not just blindly crank the pump up.

Stock was 15.2hp
.5 turns 18.6hp
1 full turn 20.0hp

Then 1.5 and all the way to 2 full turns was 20.1hp.

Basically the motor needs more air after 1 turn, so you are just creating heat with anything extra.

Also, I have a different primary spring that has a much smoother engagement ~1200rpm and about 200rpm less at cruise and WOT. Much more user friendly. You would need your idle to be around 1000rpm to be perfect.
