Ignore everyone who says you have to get a twin screw. Roots blowers and centrifugals are great bang for the buck. Total cost for my Vortech V2 (including all parts, labor, sales tax, dyno tuning, etc.) was $5100. For the price, the M90 Roush blower is not a bad deal. Not everyone wants/needs the 500+ hp of a twin screw, so the M90 is a great, budget blower (like my V2) that will yield 330-350 rwhp with room to upgrade later, if needed.
I crack up everytime someone responds to a thread like this with "I have an 'X' blower, so you should buy an 'X' blower." All the blowers on the market are good. None are bad. Some are better suited to specific goals and intended use, but just because one person has a great blower on their own car doesn't mean it's the right blower for someone else. If the OP has decided on the M90, let's keep the conversation to the M90.
That said, there are no drawbacks to putting on the M90. You'll keep your warranty intact, the car will be much more entertaining to drive, your fuel economy won't suffer much, and your stock short block will be fine as long as the tuning is done properly.

I'm ordering the Roush M90 from Yates Performance this week along with the Roush Stage 3 Suspension package. It will take a week to get here, then about 10 days to install with the PCM being shipped to Roush and back. I'll post pics when done!

PCM return takes about 3 days max, they give you an overnight box to send it in and they overnight it back to you so install should be 4 days max.
I've done an M90 roushcharger install, everything is very straightforward, but you have to "massage" some of the stock parts such as alternator and one bracket with a grinder. The hardest part of the install was relocating the wiring with minimal strain on the wires/connections. Other than that everything was a breeze. Take your time, follow the directions, and you'll be fine.
The tune that Roush supplies will keep your engine in good shape for a long time, it's pretty conservative.

This is another reason the install should not take that long.

It comes back to warranty. If I install it myself, Roush won't honor the 3/36. It has to be done by a Roush "Certified" installer and here in Cheyenne, WY, that's the Ford dealership. It's not going to take ten days to install, but I'll be out of town all next week, so the dealership will have the car part of this week (if the blower gets here) and all of next week.

Dunno, but Roush does sell a CAI for their unit
Drawback = bank account depleted faster

Off subject, but what do you think of the Ford Racing Power Pack Intake/Throttle Body/Camshafts? Do I have to add the Camshafts? Am I better off saving my money for the M90?

I was thinking of doing the same thing to my GT - the M90. Thought it was the right amount of HP for the engine. I think this topic is great, because I haven't done enough reseach, and I like ready what you guys have to say.

The great thing about adding this type of supercharger is the ability to still get good gas mileage as the only time you are in boost is under heavy acceleration. With my E-force, I can easily get in the low 20s, but what fun is that as I typically average in the upper teens as I installed this to have some fun... and not baby the car
