i have an 05 XLT F150 with a edge evolution programmer, K&N CAi, Airaide throttle body spacer and super 44s. i was wanting to put a roush super charger kit on but i dont want to have to take the space, chip and Cai offf and make them go to waste. if anyone has any ideas about what i should do let me know or is there a kit that will let me keep everything thanks for the help.

 

Build your own Centri kit using a Novi1200~2200 from a Mustang and use custom ducting. IDK why your married to the spacer it does NOTHING, the chip will need to be reburned with a SC tune and the CAI depending on your skills might be salvagable for some parts on the new air duct.

 

Spacer is worthless wether your naturally aspirated or forced induction. You will need custom tuning for your supercharged application. And that Airaid CAI is worthless as well. No offense, I had one myself. Hot air intake is more like. More gaps and openings for the engine bay air to get in then anything I've ever seen. Besides the Roush blower comes with its own tuning and CAI, as do the Whipple and Saleen which are both far superior to the heat breathing Roush. The stuff you have now is not made to work with a blower. Sell it on ebay to the next sucker. A supercharger is a whole new ball game. Big kid toys now buddy.

 

I'm just casually looking through posts and I should start my own post for this question, but if anyone wants to answer this that would be cool. I am new to supercharging and would love to do this someday and I'm just wondering when installing a supercharger do you use the f150's stock throttlebody and the supercharger goes on top of that setup or is the supercharger also in charge of throttlebody-like operation for air intake. Like I said, I should start my own post and I don't want to take away from this one, I'm just being lazy. A supercharger seems like it would kick some *** on my 5.4.

 

The blower has its own intake but most setups use the stock throttle body.

 

know this sounds like a stupid question but whats the fuel economy like w/the wipple? i use my truck for work as a driver. and i drive about 85k a year and have been dreaming bout a wipple, but dont need alot worse gas mileage

 

Well you will be using more expensive gas...91+ octane (depending on the tune of course).

 

The mpg's are up to you. If you never press it hard enough to get into boost you will get the mpg's you are getting now. Maybe even a lil better with a good tune. This has been my experince anyway. But make no mistake it takes fuel to make power. So when you floor she will drink. Oh and roast the tires.

 

I will have to disagree with this one,,, my experience with the poweraid spacer has been a good one,.... sure it wont give me performance since its for GAS MILEAGE, but I did get at least a 1.5-2mpg on my previous truck before I got my drop in K&N which then I got a combined 2.5-3.5mpg on highway (i do A LOT of highway driving)... plus love the cruisin whistle sound it makes

 

I have aroush blower the thottele body is your stock 1 it goes on top of the blower
