"the torque converter actually gives your car more torque when you accelerate out of a stop." -

Okay thank you neutrino for answering exactly how I didn't want you to. A torque converter puts the power to the ground with more torque because you don't have to worry about as much power being lost in the mechanics of a clutch. The evo is a stick. The vette is an auto. And 90hp is not enough to be able to beat an evo.. you have to look at more... such as the gearing and the drivetrain. A vette tops out at over 180mph.. an evo can't touch that. So there is more power in the vette but it's put towards the higher end.
So now that we've had that... TatII The evo doesn't even have a racing chip... so I'm guessing both cars are going to be in the low 13's because the vette has a vara ram system (most of u probably don't own vettes so I will divulge you) You all probably have seen the 2 holes on the corvettes front facia. They do nothing but house the fog lamps. So what vararam does is remove the plastic fillers and replace them with two air ducts that go into an airbox that is larger than the stock one and goes to 1 k&n cone. So the vette has 40 exta horses than normal according to the factory, and according to the factory it's supposed to get .35 better in the 1/4 mile. So it's close...
