I own a 03 f-250 with the 5.4 and i found a deal on a eaton supercharger for a shelby gt 500 and i was curious how extensive of a project it would be to fit this on my truck. Is it worth putting on there.

 

Isn't the Shelby a 4V 5.4L engine? Not sure it would adapt to your 5.4L but honestly don't know.

 

Not really feasible since the heads are different. Anything is possible for the right amount of money, how much do you want to spend?

 

not to much more than the supercharger im just a college student and cant afford new heads or anything, ill just push it off for a while i guess thanks though.

 

A machine shop might be able to make one for you that should work. In all honesty I think it would be better to try to get a turbo to work then a supercharger. A turbo is just more efficient then a supercharger. Think about all the gas engines that are having turbos being put on them after all the crap hit the fans with the pump prices. That's would I would look into doing. But that's just me.

 

Supercharger or Turbo, dont start the project if your not willing to drop around 3grand

you need injectors, harnesses, fuel pump (or boost a pump with vacuum switch) custom tune for the ECM ect.

also turbos have no power loss, unlike a belt driven supercharger, but superchargers dont have lag like a turbo can and you dont have to worry about EGT's and a variy of other things and depending on the amount of boost you are going to try to run a SC will make it sooner. but just because turbos dont have any parasitic loss isn't going to save anyone gas, you start playing in the boost with a SC or Turbo and your going to be sucking gas.

but anything is possible if you have enough money. lol

 

I dont think the triton crank and rods would take that boost verey long any way you would need a softer charger

 

It would take modest boost, boost output is adjustable y pulley size. It takes money and know how to pull off a project like that. You could spend a grand just on tuning.

 

I imagine it could take up to 9 psi of boost. Not the 29 psi of boost that I can reach just snapping my fingers, but 9 psi I think it would.

 

You don't need injectors if you match the right size turbo for the exhaust that your flowing thru in order to spin the turbo. Injector aren't necessary if you don't go to big.

That's the key word there. If you just roll into it you will: A. have very little to no lag and B. it will be far more efficient doing that as well.

Now if you romp on it, you'll get lag like you won't believe and it will suck that fuel like you wouldn't believe.

You can also lessen lag or eliminate it by getting a smaller turbo then your truck can actually handle. In other words, if your truck can handle a 54mm turbo, but you put a 50mm turbo on the truck then it can spin it faster and thus lessen lag. Put a tighter housing on the smaller turbo and that would further deal with the lag issue. Now the problem lays if you go to small then it really does counter even doing the turbo in the first place.

Bottomline: if your going to do it, turbo is the way to go, but like others have said, it's going to take quite a bit of scratch to get done and get it done right.

 

I think? paxton or vortec make a good little chrager

 

I think they used to.

 

ANYTHING beyond stock power level and you MUST purchase new injectors. This isn't your diesel,the gasoline injectors are designed and rated to flow properly and have a proper spray pattern at 40psi,and at 19 lb/hr flowrate-they only support 304 hp at the crankshaft with a BSFC of .5 (typical of a N/A engine),and they only support 271 hp at the crank with a BSFC of .6 at 6psi (typical of most forced induction applications).
Most mild superchargers/turbos will make the engine output approx 340 hp at the crank at 6psi, so you're grossly undersized if you try to use the stock 19 lb/hr injectors-you need at the very least 24lb/hr injectors,and that's at 100% duty cycle.

I can understand that for the supercharges since they are mechanically connected to the crank and your talking about a piece of equipment that uses fuel to make hp. Turbos aren't using fuel, they aren't mechanically connected to the crank and all they do is suck in air, how does that apply to turbos?

 

???
6psi is 6psi on the same engine whether it's a turbo,supercharger, or you blowing through a straw. The correct amount of fuel will be needed to compensate for the additional airflow NO MATTER WHAT. Both will need a richer air fuel mixture (or much higher octane fuel) than a N/A engine will need due to the more unstable combustion chamber-therefore the higher BSFC.
Do you really not understand how a turbochager works? It sure seems so, or you're doing you best to try for bait for an argument.

Back to your original comment....
On a gasoline engine YOU MUST HAVE LARGER INJECTORS FOR A HIGHER POWER LEVEL THAN STOCK WITH ANY TYPE OF FORCED INDUCTION. It doesn't matter how you make that power.
