MBworld guys? HDDP? Anyone?
I just ran across this thread and did some quick calculations on the SRT6 injectors... Since they are 51lb injectors (huge) they would deliver enough fuel on an engine up to 650 hp without going lean. I would definately run a dyno with AFR after installing the pulley just to make sure you aren't running lean and going to cook the pistons...
