hey guys, i was just wondering who had a 2.5" pulley on their s/c and how they like or dislike it, im considering going with one on my car, i have the 2.6" right now but i just did a full arp top and bottom end as well as eagle forged rods and sce copper head gasket. I am also running the cooling mist alcohol injection kit so i was just wondering if the 2.5 pulley would be a good mod or if its really not going to help me much, let me know guys, thanks in advance
I see 10psi with my 2.5" pulley.
Keep in mind you have to shave down some of the snout on the end of the s/c to allow the 2.5" to spin freely. Not a huge deal. I did it with a swiss army knife file on the spot in a matter of a couple minutes.

10psi definately sounds nice
a friend told me with alcohol injection i should see amost 12psi is this true? I know about the shaving down of the snout, i actually had to shave mine a bit to get the 2.6" on there, i prolly shaved enough for the 2.5" im guessing, anyone else have any feelings or info on this pulley???

well i think im gonna go with the 2.5" pulley seeing that after searching and hearing some of you guys talk there doesnt seem to be anything bad about it as long as i can keep my intake and egt's down, and im pretty sure the alcohol will do the job. Anyone ever thrown their car oon a dyno with a 2.6" or 2.5" pulley?
