I am undecided at this point if I even want to add an SC. If I do, I am not going to be pushing it hard and will keep the 8 psi boost level. Hopefully I won't need to take advantage of a warranty. I noticed that it looks like Whipple makes that charger for Roush or do they just look alike? A couple of things I don't like about the Roush is the long snout, double the belts and pulleys, what seems to be a smaller intercooler, and an air intake system that is not really a cold air intake. I am sure there are good reasons for the differences, but really can't grasp them just looking at a couple of pictures over the internet. There are things that I don't like about the Whipple, no freely available manual, uses stock injectors, difficult to run an under-drive pulley, stock narrow belt may slip under load.

Those are some of the pluses and minuses that I can think of, please add - correct

It is a cold air intake on the Roush

I don't have any personal experience but it seems to make since if you pay for a CAI, it should actually draw in cold air? The one on the Roush and similar setups will not! I am not confident that a non sealed intake system will hold up under adverse condtions, rain, dust, etc..

The Roush with the open intake is the old non intercooled one

All I have to go on is what I see on the Roush web site and there is no sealed CAI that I can find for a 2004+ F150. But hey, that doesn’t mean there isn't one, and that doesn’t mean that I don't believe you, it just simple means I haven't found it.

Just some thought.
