I can't say i know enough about the mechanics of this to say whether or not it's possible, but it seems unlikely to me, and everyone i've told about it says it's BS:

My friend has a 92 Z28 with the LT1. He recently went to canada to buy twin turbos with 425hp each, at $3000 a piece. He claims that with this added, he ran a 7 1/2 second quarter mile. That's damn fast, and i want to know if he's mistaken.

 

Moving to Theoretical and street racing forum.
