i want to learn something, so i'm going to ask here.

what kind of piston engineering do we see in the stock evo piston?

i'd like to see how smart our aftermarket companies are too. companies like ross, je, aria etc. do they use squish engineering and do they use certain shapes and certain types of coolant (oil) passages and what not? how do they take advantage of tumble and swirl? let's see pictures and explanations of all the "features" that evo pistons have.

 

Great question, sell us on some pistons!

 

man..i forgot everything about pistons ever since i got out of engine repair class

 

EVO pistons don't take advantage of squish. They have like .120 deck height. They do have a hollow section just under the dome. Obviously used for better cooling.

If you want to ask any specific questions just ask me. I work at JE Pistons
