I'm a little confused about the horsepower ratings on the 09 5.4. I thought they were 300hp/365 ft.lbs torque on gas and 320/385 on E85. I have read otherwise 310/375 on gas. Does anyone know what the true numbers are?

 

310/365 on gas 320/390 on E85 from everything I have read.

 

^^^^^^ What he said.

 

Does anyone use Ethanol?

 

i cant find the ethanol around here, i would like to get that extra 10 hp and 25 ft/lbs

 

I think those numbers are backwards. Ethanol doesnt increace power. It lowers it and your fuel economy. The only reasons 2 buy it are price and its a renewable american fuel.

 

Actually, the power is higher with the ethanol. See for yourself. Get Specifications for trucks, like the Ford F-150 pickup, here | Ford Vehicles

However, you are correct that it does lower your fuel mileage.

 

Ethanol makes more power, however your engine drinks it like a drunk drinks Jim Bean!

 

Might have 2 try it. A buddy told me his car ran worse on e85.

 

E85 67% the nrg of gasoline so 67% the range, and should be min 67% the price too. But can make more hp/tq.

 

If his vehical is not designed to run on e85 then he prob wouldnt see any increase.

 

Worse yet the E85 is much more corrosive to your seals and fuel pump can be damage from what I have read.

 

His car is one of the earlier e85 ford cars.

 

Has anyone put it on a dyno to confirm these numbers? And are they at the crank or wheels?

 

All the numbers posted by manufacturers are crank numbers.
