2004 Honda s2000 Power Pages

Conclusion
With the newly installed exhaust and TWM throttle body setup, along with tuning using an AEM EMS, we netted an overall gain of 21 hp and 20 lb-ft of torque over our baseline run. With a 26 hp increase at 7,700 rpm and 25 lb-ft at 7,200 to 7,700 rpm, the improvement or engine response throughout the midrange to top end were greatly improved as we took to the streets for some spirited driving. While the redline was increased to 8,600 rpm for all intensive testing purposes, we recommend you keep the revs to a more conservative level if you plan on keeping your engine healthy for long-term usage. We should mention that a set of aftermarket camshafts and a free-flowing header would add additional power to the already potent power plant if you were looking to add some more ponies to your S2K.
