I don’t know… any Cobra with under 300hp to me seems just wrong. In fact, I would expect them to be more than 350hp. I know that is not the case, but it SHOULD be.

Whats stock on the 98s? 300?? so it might be on par with your numbers....your mods might be hurting your number on the dyno.. what is your times and trap speeds? that might be able to tell you a little more. If your pulling low 13s then your probably making more than 260.
