To evaluate the true power potential of the K20A engine on this 2.0l Civic, I sent it for a dyno-check on a reference level Dynojet chassis dynamometer. This dyno-check was made possible by TOVA's main sponsor Afterburn whose manufacturer Aerotech also operates Dyuojet Far East for the marketing and servicing of Dynojets in this region. The dyno-check was part of a 'payment-in-kind' package for their advertisement here on TOVA.
The Dynojet measures power at the wheels which is the resultant power after losses incurred from engine ancillaries (like the air-cond compressor) and the gearbox. In this case, there are 3 main factors to note when looking at the result of the dyno-check. Firstly would be the rated max power of the K20A engine. This is spec'ed at 155ps as we already know. In terms of parastic power losses due to engine ancillaries, the EPS used on the 2.0l Civic is an advantage here because it does not require a hydraulic power steering pump to be driven by the engine. So instead of the usual 3, there are now only 2 devices attached to the engine - the alternator and the air-cond compressor. Then finally the 2.0l Civic only comes with a 5-speed GLC automatic gearbox which loses quite a bit of power when compared to the standard 5-speed manual gearbox or even the CVT as used on the Jazz and City.
I SAW A FEW RS MODEL AND THEY HAD DRUM BRAKE SET UP, BUT LAST WEEK I WAS IN THE BAMBOO AND I SAW A WHITE ES CIVIC WITH DISC BRAKES
