Guys, I noticed that the roush f-150's EPA mpg rating is 12/14 mpg. The stock 5.0 is 15/22. I'm averaging 20.0 for the last 30,000 (supercharged) miles. It's within 1 mpg of my old ecoboost truck. Any idea why the roush rating would be so bad? What are y'all getting?
There's been a few others that have said something similar with boost. If you can keep your foot off the pedal, it seems you get better mileage. My guess is that the engine not having to work as hard to pull in air is what helps.
All that's left is to assemble throttle body, install air box and run the wiring for fans & pump. Hopefully I get my tune emailed to me so I can fire her up the day I Finnish.
I'm about to pull the plug on this project. When installing the coolant reservoir, did you have to remove the front bumper, or were you able to insert the brackets into frame box rails with bumper in place?
My kit is uninstalled and will be listed for sale shortly. I purchased new supercharger oil and spark plugs so it will be a nice fresh kit.
I also purchased new heater hoses for my truck so I can include the already modified ones with the kit and I will also include the custom fan switch I added to be able to turn them off if wanted and the required lower bumper grill. Only thing you will need is fluid to fill her up
I just received the new oil, plugs and pieces from Whipple to make this kit ready. Shoot me some offers and lets get this thing spinning some wheels again
I’m headed to Kuwait this Sunday...can’t have things like this show up while I’m gone. I’ll be watching this though...if it’s not sold when I come back in Nov I’ll be in the market. This trip is solely to finance my Whipple.

I finished my install a couple weeks ago and so far I am loving it! I do have one complaint, the fans. They are kind of loud. I drove the truck for a week without the fans and, besides the heat exchanger rattle due to the mounting bolts bottoming out on the bumper bolts (see earlier replies), I didn't notice any difference besides the fan noise. Has any one else here gone without the fans or implemented a work around to shut off the fans? My truck is my daily driver and I would rather have a quiet drive thru experience than the extra few horsepower that might be had with the fans running all the time. Thanks in advance for any suggestions!
