What are the stock fuel systems limitations

[impactblue]

For now I still want to run pump gas. Very conservative. Power isn't my goal


I was saving for a new fuel system but the 2015 mustang kind of got under my skin and took my mod money.



It's on a simple street tune we used to break the motor in. I've ran it up to maybe 5000rpm once or twice and there are no signs of a lean condition at all

Wondering if I'm good with what I have till I switch over to e85

Do ID1000s and a boost a pump and maybe some bigger fuel rails if you want and that will support around 800whp
All stock fuel system will support around 750whp. I'm guessing your car is making around 750whp at this point with your mods. So E85 wouldn't be a bad idea

I would hope I get further than 750 :/

I mean I made 727 before heads cams and built motor

I would definetly go E85, if you have it available in your area.

I didn't know that, well than ya you would probably be best to go E85.

Corn here also, ID's 1,300, fuel boost pumps, and some Fore fuel rails. Just call Van.

My car makes 757/777 on 93 pump and there is still plenty of fuel according to lund.

On pump gas you will run out of octane well before you run out of volume. The switch to E85 is where you will start to see flow being a restriction. That's the boat I'm about to hop on board.
