It will be fine I'm sure for short blasts on 92 octane, but its still on my mind when putting the motor on the edge. I just wonder if tune is worth it running on the street on 92 octane pump fuel if the intake charge can't be cooled better.
It depends on what your after. The SC pulley will do for most members out there who just want to go fast. If you want to be any quicker than 12.1's which is crazy fast than you'll want a crank pulley. Like I said most members are content with the SC pulley. If those of us with 178 pullies listed all of our 11 second passes on dragtimes it would take up the 1st 2 pages. Speed is addicting and at some point that sc pulley won't be enough. The 178 is the only pulley that's been around longer than the srt6.
