That is a funny story. When you think you have a hot car you soon find out which ones are hotter!
I have no doubt a Legere-spec 2.0 could get a GT in the 14s, but there will be more to it than the engine. First, 3.44 gears aren't gonna get it. The poor little clutch will not like this game, and from the advice I keep getting about the rear end, the Camaro diff would be advised.
Let's see one! Who wants to show us a 14 second GT? My first tip, lighten up the front end some. Move the battery to the right rear corner. Remove the front bumper. Put worn out shocks on the front, it adds instant front rise/weight transfer.
Use every trick in the book, surprise us. You might get into the 13s even!
Quick (not fast, but quick, there is a difference) cars are the result of high horsepower to weight ratios, good front to rear weight transfer under accelleration, a rear gear that makes the tach hit red in high gear just before the finish line, and good tire traction (a science in itself). Try it, it is fun.
