How is the Allen supercharger kit for the 97 f150 5.4, Is there any place to find it for cheap or is troyer the cheapest?

 

i cant remember who it was but someone was using one and said that the blower worked well..Phil maybe...damn i forgot

 

Yes,,Me...lol
The Allen is a very nice kit.
It was my first blower setup. Stock it puts out 5 PSI. I think my supercrew ran a 14.99 1/4 with it stock.
Then I added an smaller upper pulley and a custom crank pulley,#42 injectors,90mm mass air,Snow water/meth kit and it was badazz. Till it blew a head gasket...lol
I sold it for $2100. so if you can find one used,,go for it. Otherwise,,,plan on spending 4K.
I think I paid $4300. from Allen Engine Development.

How much psi can I run on the stock engine without killing gas mileage and breaking anything?

 

The way you drive it will determine your gas mileage!
If you can drive it normal,,,you should get better mileage but if your in the boost all the time your mileage will go down.
You probably shouldn't go over 7 or 8 PSI on your stock block if you want it to last.

allen makes top notch products. never heard a bad thing about them

 

allen superchargers went out of buisness a while ago. i got stuck in a bad situation needing parts that werent being made anymore. i had to go the custom rought with the stuff i had. Never heared anything bad about the superchargers though.

 

I give the kit a I run the stock pulley 42lb injectors, 90mm MAF and Troyer tunes.

 

Did Troyer buy them out? The website still shows them available but havn't called to see.

 

nah they just havent updated there web site yet. He was the first place i called for parts but they are all out of everything. try ebay one pops up every once and a while.

 

AED is out of business, you can call all day and not get an answer. I really wanted one of their kits. Well now on to a different route.
