In most situations, a centrifugal will make more peak power than a twin screw - centrifugals will make more boost with less drag and less heat. The problem is though, that the centrifugals will only make that hp at high rpms and 95% of street driving is below 3500 rpms. But, when I want to get on it and let it rev I've got all the power that a twin screw can give me, right where I want it - up top. Hey don't get me wrong though - if all things were equal (price) I'da probably gotten a twin screw though.

well whats the best for running 1/4s in a 03 cobra, speaking of which i went to my step bros dealer and test drove 2 i was in heaven, one already had a magnapack exhaust it was so sick but that one was a 01 cobra, it had 35k miles and he could get it for me for about 20k i was so tempted but i'm pretty set on a 03-04. they only had one other cobra and it was a 04 with 500 miles going for 30k i woulda got that but it was a convertible. so hopefully somethin comes in soon which they should be because people will be trading in i think for the newer cars.

Wings, buy the 01 Cobra for 20 K and you will have 10k to spend on a KB twin screw, headers, tune etc. you will be faster than the 03 i believe.
