Fresh from dyno.
Three baseline runs were done to find the sweat spot for testing temp and a 4th run done removing the air filters to see the effects. All runs are SAE corrected utilizing a dynojet dyno.
The first run was with an oil temp of 180 (usually do water temp, but being none are available) which yielded 277/231 torque. After five minutes a second pull was done with an oil temp just under 200 degrees which yielded the best run of the three of 275/240. (fyi 282/246 std) Even though peak is slightly less, the overall power was significantly more. A third run was done with an oil temp of 220 with power going down to 273/236 indicating the car likes oil temps just under 200 degrees. Really wish I could do better water temp readings as this is usually what I go by in establishing a baseline for consistency.
The car was allowed to cool down to 195 oil temps (best run temp), the air filters removed and redynoed. The results were 274/239 which tells me I may have pissed away 90 bucks buying the Corsworth high flow filters making me even more skeptical of an 18 hp gain in just intake.
Air/fuel ratio are pretty rich for a N/A setup mostly in the mid to high 11 to 1 range which tells me one of two things: These care either like it rich, or the factory is sandbagging. Tuning software should answer that question.

If anyone is slicker (probably a ton) than me at embedding images into posts...I send the scanned file and you can add.
