My daily driver is an 03 Silverado SS w/a 6.0 and a Radix intercooled Magnacharger. I'll have to say that thing blows my mind every time I punch it all 4 wheels go up in smoke. I consistantly red line it and it never complains! I run 9 psi of boost but, even before the supercharger it was an amazingly powerful engine, and smooth!! I'm going to put this setup in burrl after this season. 6.0, 4L60E, rock solid! :icon2:
