Miata ITB DYNO Test # Plenum vs Open Trumpets # ITB Power Gains

This dyno day was a good opportunity for some testing as well. Keeping the base map at the ecu we checked how the plenum performs, how filters affect power and also the difference of open to closed hood during the dyno run. Then we started fine tuning the ECU.

Franky did very well, hitting 200hp and more than 20kgr of torque.! Konstantinos @akina_downhill did an amazing job one more time squeezing every bit of power througt the powerband. The car feels really nice while the sound is glorious!
