This is very important for all of you interested in modding your H22 motors! Let me describe the two H22a motors first:
motor 1: JDM H22a with 11.5:1 compression, aem cai, dc header, apex ws exhaust, b&m fpr, dyno tuning for fuel pressure and ignition timing.
motor 2: USDM H22a4 with type-s cams, skunk 2 cam gears, Field VTEC controller, AEM tru-time 3 pc. pulley set, Iceman CAI, HP racing header, Nakayama muffler with 2.5" piping, dyno tuning for cam gears, and vtec controller.
Ok, now stop and think about who should win this test. Motor 2 right? After all, it has way more mods. Well, at least that's what I thought. Check out the results, the first numbers are motor 1's hp/tq, the second numbers are motor 2's hp/tq, the 3rd set of numbers are the difference between motor 1 and 2 (i.e. motor 1 - motor 2):
4k rpm - 104/137, 93/123, +11/+14
4.5k rpm - 115/134, 103/123, +12/+11
5k rpm - 135/140, 105/120, +30/+20
5.5k rpm - 155/147, 137/125, +18/+22
6k rpm - 165.9/145.2, 156/129, +9.9/+16.2
6.5k rpm - 174.5/141, 168/135, +6.5/+6
7k rpm - 176/132, 174.4/130, +1.6/+2
7.4k rpm - 171/122, 170/119, +1/+3
It's pretty obvious that motor 1 here is beating motor 2, even though the 2 motors have similar peak hp numbers. Using the above data points, motor 1 averages 11.25 or so more hp across the rev range, and 11.775 more torque.
Motor 1's data is from my dyno chart.
Motor 2's data is from the following link: http://www.geocities.com/timn_1/type_S_Cams2.html
Hope you guys found this interesting, it sure took me a long time to do the math. Hope you guys appreciate the info
