I recently purchased a 1997 TJ (4.0 32RH) for some projects I am working on. I am planning to do some tuning sessions on it to get some base files for my tuning business. As part of that process I am going to be on the dyno in a number of different configurations with different mods. As a part of this process I will be able to get dyno data from a range of different engine mods. This is a list of the mods and configurations I am planning on testing.
Dyno 1 - Stock Un-modified
Dyno 2 - Stock With Tune-up Done (Plugs, Wires, Cap, Rotor, Clean Injectors, Filers)
Dyno 3 - Add Windstar Filter
Dyno 4 - Locked Up Fan Clutch
Dyno 5 - E-Fan
Dyno 6 - HP Tuners Tune, All Further Mods Will Have Tunes Optimized For The Mod
Dyno 7 - Add Header
Dyno 8 - Add Bored Throttle Body
Dyno 9 - Add Exhaust
Dyno 10 - Add Headgasket, Milled Head and Cam
If there are any other modifications that anyone would like to see, let me know. I don't want to spend lots of money on this testing, so things like the Edelbrock head and roller rockers I'm not planning on testing, unless someone is willing to donate them.
Also, if there are any specific methods of testing that I should consider feel free to mention them as well. I won't be able to do it all in one day, so there may be some temperature differences and such. I think overall it will still give a good overview of whether or not these mods are worthwhile, as well as giving me data for base tune files.
