Dyno Tips

1. dial in jetting (A/F) with your setup
2. observe A/F reading for 13:1 air fuel ratio. below 13 on A/F, jetting is rich. above 13 on A/F jetting is lean. go to step 3 not until 13 is obtained throughout rpm range.
3. next observe hp curve printout, if power increases all the way to rev limit on plot then your done; if not go to step 4.
4. degree cam (retard cam timing) to push torque up towards rev limit. Because hp= (torque x rpm)/5250, the more torque you can push up in the higher rpm's- the more hp the engine develops. 5250 is where all torque and hp curves cross (see dyno plot attached). If the goal is hp, then retard cam timing. if the goal is torque advance cam timing. find desired cam timing- go to step 5.
5. dial in for new cam timing to optimize newly obtained power.

try looking at the dyno below with a calculator and pick any rpm, then use the equation in step 4 and you'll begin to realize how to obtain hp or torque ;)

hope this helps.
