Is there ever "never any more" ???

And it pushes me to wondering.... "how fast could a simple combo really go?". Somebody runs 12.50's with a car and most think it should go 12.9's, so he has done well. But what about 12.3's, is that in it? So 12.3's is reached, why not 12.10? Is a 11.99 really in that combo? By then, nobody believes it is what it is, but it actually is ... lol. So is there a stopping point? Who knows... But I do know it cost hours and hours of a person's life and some money test'n'tun'n to try and find out!
This is why......as you know the engine is actually the LEAST of the package. The rest of the car is far more important.
