I'm kicking around the idea of putting a 2.2 KB on my 03 Cobra and I would really prefer not to have to mess with the input shaft. My goal is around the neighborhood of 600 RWHP and i'll be keeping street tires on it. From what I understand the general limit of the shaft is 500 RWHP but it won't see any hard launches with sticky tires. Do you think I would be in the clear?
