You know you can wear an engine out on the dyno. So decide how many pulls
you are willing to make...and then decide which variables will possibly gain
the most HP...and play with those...
Ign. Timing
Different Ign. Systems
Indexing Spark Plugs
Wider/Narrower Plug Gaps
Valve Lash
Cam Timing
Bigger/Smaller Cam
Jetting
Bigger/Smaller Carb
Header Length
Nitrous
Different Nitrous Settings 100/150/200 HP
What else?
