Meaning that the engine would not run right, would not deliver power properly, and would self-limit it's speed.
I don't see why the engine would lock up!?!?!!? Are tolerances close enough that you have valves and pistons hitting each other at this speed? Or am I just not getting it?
I don't believe we have interference engines but, I ain't gonna try it.
In any event, have you hit your rev limiter at high speed. It just shuts the thing down. Even for a second, you don't want that at high speed. You can lose control of the car quite easily at 140 MPH.
It will instantly turn your Crossfire into a short range cruise missle. You know they don't put landing gears on cruise missles for a reason.
