The reason that the intercooler is larger is because it is air-to-air vs Vortech's air-to-water. Different designs, same results. As for ATI...hmmmm, a good friend of mine owns a local Mustang shop and has done many SC installs. Vortech, ATI, Paxton. The only cars that have failed in some way after the SC install have been ATIs. They have all failed for different reasons, but no Vortech or Paxton cars have failed. Probably a coincidence, but worth noting.
ATIs seem to make more power though.:smile:
Check to see if ATIs kits come with injectors, for some reason I don't think they do. And they will recommend 42# units for our cars, at a cost of around $400.
You gotta ask yourself this; If it's the same price and includes an intercooler that normally runs $1000+ where are they cutting corners to make any money?
Needless to say my vote is Vortech, all of the units I have owned have run flawless the entire time I owned them.
Before you buy anything be an informed consumer. Call all of the companies you are looking at and ask a lot of questions. Talk to speed shops in your area and ask a lot of questions. Talk to people that own each one, see why they bought the one they did.
