Anything can happen. I've seen little beat up looking Honda Civics run high 10 second 1/4 miles and the car looked like it wasn't worth $50. Obviously a fair bit was spent on the engine to make it a 10 second car. I've seen a lifted diesel Suburban run a high 11 second pass. That was an amazing sight - it looked like a white school bus moving at warp speed - incredible.

So can a Caliber SRT4 on juice take down an SRT6? Sure, with the right shot. You can make anything fast pretty cheaply. But making it really fast AND really reliable can be tricky.
