Dyno was with the 20" heavy chrome so you know it will be allot more with 2 changing factors. 1. Dyno without the 20's 2. Dyno at a regular shop with regular Dyno wheel rollers. Can't wait for PowerChip Tokyo to open in October to have my ECU tuned. After my ECU being tuned I may consider two other options. 1. Have my heads polished and increased to 3.8liter with maybe a renntec camshaft 2. Supercharger Dyno Explanation File1 (Red Line) - Dyno with 20's before KMACs File2 (Green Line) - Dyno with 20's after KMACs and Evo Pulley File3 (Blue Line) - Dyno with 20's with new custom Headers Sound did not change in decibels but did change in frequency dropping by about 20Hz. Unofficially HP increase +7 Torque increase +28 = 16% Increase I say this is unofficial because I went to a tuning shop that has heavier Dyno rollers than normal because they said they want to test actual road resistance. With that being said here are the numbers Before 165.11 RWHP @ 171.42 lb-ft torque After 172.01 RWHP @ 199.63 lb-ft torque Even before the Dyno driving home from the shop, I noticed smooth consistent acceleration. From a stand still you feel a tingle of enjoyment in the 1K rpm range and while rolling driving moderately you feel it around 2K, and a some aggression around 2.5K and increasingly becomes a monster in the 3-5K range. --------------------------------- MB Original CLK 320 Engine Specs Horsepower @ rpm = 215 @ 5,700 Torque (lbs-ft.) @ rpm = 229 @ 3,000-4,600 Wheel/Tires = 7.0x16-inch 205/55R16 More information can be found here from this Guy http://www.marcusfitzhugh.com/CLK/spec.html
