Well after lots of reading and swinging a deal with the wife, I think I'm almost ready to order a non intercooled Roushcharger but just have a few more questions that hopfully some Roushcharger experst will answer!

I live in Canada and its common to see -35c in the winter, will the s/c like that?

Will pulling a 6500lb camper be a problem? (Approx 2000k per year)

Is the CAI that it comes with really noisy in the cab? I had an AEM on my truck for a while and it was really bad in the cab when pulling the camper.

How will fuel milage be affected? I know it will go down as it will be hard not to mash it all the time, but I'm talking just cruising on the highway.

Oh ya, will it have that cool super charger whine!

Thanks Guys

 

I cant tell you for sure about the f150 with the roushcharger but I can tell you that a CAI isnt noisy in the Roush mustang from inside the car ( and mine is a convertible not s/c though). And the supercharger does put out a lovely whine but not as loud as say a procharger. I would suspect the colder the temp the happier a motor but that is darn cold. The SC mustangs I know in areas not even close to that temp are garaged in the winter. Never heard of a problem but that doesnt mean much. I am pretty certain pulling a trailer will be a pleasure. Mileage will be down mostly from mashing and I think you may need to run higher octane(could be wrong). Roush has a good following in my part of the world. Might check stage3motorsports.com for prices. These are just my opinions as I am in no way highly educated in superchargers as my stage 2 is missing that mod. D

 

bold stuff above.


I had the Non-Intercooled RoushCharger on my 2006 Screw FX4.

word of caution for you

 

Thanks guys, I'll get in contact with Mike to make sure on the winter thing, and then order onr up!

 

btw, make sure you buy it from Roush on eBay. They are posting it from $2,100 to $2,400 depending on their mood.

Best price anywhere.


Have fun with the kit. It's lots of fun

 

What do you search on ebay, I couldn't find any from roush?

 

Search ebay at least twice a week for a while I bet you find one. They are out there just be patient and you will find a decent deal, D

 

eBay - Roush Overstock Store

N/I RoushCharger + Goodies - Bit of a rip-off though. They're adding $175 for 3 badges and a grill. I've seen that grille sell for $99 shipped.

Basic N/I RoushCharger


e-mail/call Roush and offer them $2,100 + shipping for the kit. They'll take it. I've seen many many of these blowers go for that price

 

does eaton still make a s/c for the 4'6/5.44?

 

I talked with Mike Troyer today and even though he didn't tell me what I wanted to hear, we had a great chat about the 5.4's! So my blower idea is on hold until I have enough cash for the intercooled unit. He said that with the non intercooled blower your towing capacity is actually cut in half as the egt temps will get too high for the exh valves and seats. With the load I need to pull this wouldn't work for me.
I did end up buying some custom tunes from him and got a couple of other ideas for the future.

 

I know quite a few guys who tow using the N/I blower.

with custom tunes...yeah, you are cutting a knife edge. With the stock Roush tunes...not so much. The Roush tunes are extremely safe. You don't even get fully into the boost until you hit 80% throttle.

Mike Troyer is the man for the 04+ F-150. But how often do you get over 50% throttle when towing?

 

You mean you don't need to drive them with the blower making a high pitch wining sound all the time? I thought that is what my manual said.....

 

Isn't the boost bypass valve vacuum controlled? I wouldn’t think the state of ECU tune wouldn't make a difference when, or at the rate in which it opened and closed? The only thing that should really control that is pulley size? My guess is that that Roush fuel and timing curves are set really conservatively and pull a lot more timing out under load than the Troyer tunes? Great for safety, but its done so at the expense of horsepower and torque.

Also, does the Roush kit include an injector upgrade, or does it incorporate some sort of electronic FMU onto the fuel rail to increase delivery? I would think if it doesn’t, a switch to a properly sized set of injectors and calibration to the fuel mapping through the ECU would net better drivability and potential power and torque across the entire RPM range, no? What size are the stock injectors in our 5.4L’s? I’m guessing what....24lb/hr?

I wish Roush had a better detailed description of the kit in their ad!

 

The non-intercooled version is just bolt on with a custom tune.

The intercooled version comes with new injectors and 0 degree plugs as well.

 

I don't know how often I'll be over 50% load but I know ther will be times and I don't want to take a chance and blow my motor. I'll just have to save up for the intercooled version
