DYNO: Toyota Celica ST185 GT-Four Group A - Custom Cars & Coffee / MPC Dyno Day

On the 27th of April 2019, Custom Cars and Coffee ran their inaugural Dyno Day at Melbourne Performance Centre.

With amazing facilities and some even more amazing cars on display, it was a great day out and good chance to throw my GT-Four on the dyno and blow the cob webs out.

I was happy that, after 4 years since it's last tune, it still put the numbers down with a clean and smooth run - resulting in 212kw at four wheels.
