Have to agree with Onebadgt, never go with a roush s/c. If you want a roots style charger it comes down to Whipple or Kenne Bell, neither one is better than the other its always been a constant arguement between them on which is better. Once i go eaton, then get my motor built, i already know i will upgrade to a whipple, i have just liked the way those preform to me. Also for parts shopping dont go to MPH, they cost a arm and a leg. The only thing tim lynch(sp) is better at than any other mustang shop is tuning. For parts though, i am going through LethalPerformance.com by far the best online parts selection than anyone else, and the do compete on prices. I am always emailing Jerry of the workers on SVTPerformance all the time on prices and parts, and hes always helpful.
