Phantom Motor Corp Line of Engines

Phantom Motor Corp’s line of economy engines for hatch back’s and small sedan’s. Pleas give feed back :smiley:

Quick Question, Why are you engines running on 95 RON? shouldn’t the everyday eco engine be able to run on the everyday cheap gas of 91 RON? just wanted to know why you went with the 95

As for the answer for the above, the basic petrol octane count in Europe is 95.

As for the engines, the first one has a very odd shaped torque curve and this may be down the bore and stroke ratio. You may want to rework that.
