Ford lists the power peak at 6,500 rpm and the torque peak at 4,250 rpm, so it would need a pretty loose converter and some gearing. The Stock Classification tool lists the throttle body as being 2.913" (74mm). And first gear in the 6R60 transmission is 4.171. |

Re: 2015 Mustang Ecoboost K/SA?
Anyone look at NHRA engine blueprint specs ? Max compression 15.52 to 1. Are there any errors in those specs?

Re: 2015 Mustang Ecoboost K/SA?
I wish someone could tell me how to do that! I'm building a NA version of this motor and there isn't enough dome and head milling to get that under any condition.

If you follow the Specs and do the math, it comes up at 13.98. Not sure where the max compression of 15.52 comes from. I'm with you, I don't expect you will get 15:1 with around stock bore and stroke. To get there would require a TDC volume of around 40cc. Tough to do with a deck clearance that seems more workable than the Spec of .023. |

Re: 2015 Mustang Ecoboost K/SA?
So is this a dished or domed piston?

Re: 2015 Mustang Ecoboost K/SA?
No, this is a motor for SS/Modified. Pretty much all of the dome and smallest combustion chamber and still getting enough valve relief gets you in the 15:1 range. I currently run the 2.3 Ford single cam engine but am in the process of building a Duratec motor which is an Ecoboost without the turbo.
