A few months back we put our test FN2 on the dyno at an organised RR day. With only 4K on the clock it supried everyone by making 212bhp. This wasn't we believe a fluke reading as it made the same figures on 3 consecutive runs and on that day EP3's were making stock and expected figures with given mods.
6 months on and now with 10K on the clock its time for testing with a few parts that are available.
We started off by testing the car totally stock. This time we made 208bhp/148ft/lb
3 runs confirmed 1bhp either side of the above figure. This was our datum.
We then tested the Hondata Re-flash.
This has been extensively covered in varous press releases and posts before and driving the car it transforms the midrange driving experience.
Results on the dyno with the stock car showed significant midrange gains in power and torque but only 1bhp difference at peak power.
Next the AEM intake was fitted followed by the new HKS twin exit exhaust.
Results as shown below.
The fitting of these 3 basic modifications together resulted in gains of 22bhp & 15ft/lb
All work was carried out with dyno runs within 4 hours of each other.
Significantly also the car was only running Shell 95 Unleaded fuel.
The dip in power/torque at 5K is due to the car running rich at this point. The Hondata ECU is mapped to account for intake, manifold and exhaust. Fitting a race manifold will lean this out and deliver again significant gains right through the powerband.
