Can someone tell me how many psi the stock 2015 Mustang GT Coyote engine produces? Planning to purchase/install a supercharger but need like to know that information first to take into consideration to project total boost. Can't see to find the answer online or looking in the wrong places.

a naturally aspirated engine doesnt make any boost. lmao

The 5.0L GT which uses the Coyote engine is naturally aspirated and does not have boost. I think you're confused with the Ecoboost Mustang which has a turbo in it? The Ecoboost, IIRC, produces 18 psi of boost, as already mentioned the V8 and V6 produce 0 boost since they are naturally aspirated at stock.

Thanks for the quick response...even though it was a source of entertainment! Since I'm a novice at this, may I can rephrase and you can help me out. From what I've been reading, you shouldn't go out and just but any kind of supercharger since your engine may not be able to handle it. I'm looking at the ProCharger line and the units I'm considering either produce 8 psi or 9 psi. So, if you don't mind, help me understand. If I have a supercharger THAT produces 8 psi, that's the total pressure I can expect for my engine? I'm trying to ensure I don't buy more than my car can handle.

the boost pressure advertised can vary due to variables, such as cams, intake design, air inlet to the supercharger restriction, volume of the air inlet/intercooler, etc. if its advertised at 8 psi you can expect to see a 8-11psi range depending on those variables. your engine is more than able to handle the variance.

okay...thanks! explains why i couldn't find anything since i was misunderstanding. somehow i got vacuum mixed in there as well. but i appreciate the explanation. looking at the ProCharger HO (complete kit). do you have any experience or comments about that system?

jwog666

i dont, but if you post in the boost section you may get somebody who does. you wont regret going forced induction, nobody does.
