Here are a couple vids of that LS3 car I was talking about. The first one has a complete detail of his mods...
well less than $10K It also shows hims absolutely spanking a 700 hp HPF Turbo M3.
The second video you will need to fast forward through all the gabbing...this race was for $$$ and more
importantly to shut up the guy with the built motor who was talking all the crap for a week. Mind you the slower Vette
has spent a ton more and dynos at 800 HP.
