Livernois is kicking some *** with the Ecoboost mustang and the 5.0!!

 

Great post, presume the #'s are SAE J1349 ?
Nice to see what each mod adds.
Were you surprised @ the # after the header install, not even 20 hp ?
.

 

Were there any comments on your base pull? With a 18% factor you are at approximately 466 crank HP. Just curious if all the 2015 are producing those kind of stock numbers. Very impressive.

 

Nope. 445 is pretty normal for these modifications. Dyno can differ day to day too. Could have been 25 for headers, baseline wasn't same day.

The 426 could have been high? 420?

End result is all that really mattered to me for the winter. Soon as track opens, I'll be there

 

Most are pulling 390/393/395 completely stock. Dan was impressed with all the numbers. And as far as the headers, to his recollection that's a good pick up based off the 14 cars.

The factory headers are pretty good from the start.

 

Great numbers! Thanks for posting the gains after each mod
