this is like asking whats better ford or chevy. You are going to get 60 people to respond and they will all be different. The major players in the centrifical are Vortech, ATI, and Paxton, in no particular order. Kenne-bell is a whipple charger, is a different breed. Ford Racing will probably be comming out with the Cobra Blower in the near future, which is a roots blower...
Here is a run down (mind you this is from a guy who doesn't own a mod motor blower car, but did own a blower 5.0)
Vortech S-trim Hot Air type. offers air-to-water, type aftercooler, for extra cost. 8 psi 3 year warrenty. offers larger blower for higher horsepower
Paxton Novi series offers two models. The novi 1000 and novi 2000. Most people seem to like the 1000's although they make less power, then the 2000. The 1000 is slightly smaller then the S-Trim and the 2000 is slightly bigger. Some people think that the 1000 is to small for a v8 street car, while the 2000 is to big for a v8 street car. they offer a air-to-air intercooler for extra money. Doesn't offer anything more then the Novi 2000 Not sure about there warrenty, I think it's one year
ATI, offers a variety of models, but the P1SC and D1 are the favorites for the street/strip. Jimmy V, runs this blower, and is believed to be the highest horsepower 2V in the country. come with a air-to-air intercooler. These seem to make the most power, but alot of people blow motors with them as well. They have some reliability problems with seals and run on there own oil, verse the cars oil, because of this they don't require you to tap the oil pan, but every time you want to change your blower oil, its expensive. they offer a 3 year warrenty for a small fee
Saleen (GT blower)
roots type, M90 blower. gobs of torque down low, flat power curve. air-to-water type intercooler included with the kit. Great blower for a street car, less then ideal for a strip car. 1 year warrenty
Whipple charger, using the auto-rotor. they have a 1.5L and a 2.2L. Although it's not out yet for the 99-up cobra, it's expected out soon. It is the blower that they put on the new saleen s281E. It is similar in design to the roots blower, but it doesn't have the problem with high intake charge temps, and you can push alot more boost through them. The 1.5L can make 18 psi, safely.
my fingers hurt from typing this much, hoped that helped
