Wow, that is such a nice example!
I am NOT jealous

I too was amazed at the difference between the 603 and the 617. The five cylinder seemed like a tractor engine compared with the six.

For even more performance you can remove the ALDA and set the boost pressure up to 13psi. My SDL was only making 7 psi of boost when I got him...
