DYNO Results - CLK320 Hi Flow Exhaust Manifolds / V6 Headers




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.
