what would I need to get there? Assuming my forged motors in, my trans is built, I'm getting s292's over winter, and a v2 strim. I'd rather keep the car 6 rib, so what would be the smallest 6rib pulley i could run without slipping, maybe an rr 3.1 or something of the sort. would that alone with the cams be enough for that power? it'd be intercooled, 93 pump gas, etc.

If you want avoid belt slip, look into getting an OD crank pulley as well. This will allow you to run a larger blower pulley (to avoid slip) yet still get the boost numbers you may want/need

the only o/d crank pullies are 400 some dollars, i can do a complete 8rib for half that. but if a 6rib pulley wont get me there then i'll do a 8rib swap to drop down to a 2.8 or so.

I am running a 2.87 on a 6 rib right now.

The dyno graph doesn't show belt slip, but the belt is definitely slipping. There is black crap all over my timing cover.

yeah i've never heard of anyone with a 6rib running smaller than a 3.0. maybe you're just getting lucky tho man? lol

I hear turbos don't belt slip issues

turbo's aren't free, i'm getting the blower free from my buddy for doing so much work on his, as he's upgrading to a ysi.

My car also has an unknown issue that is causing me to put down 100+rwhp than it should be sooooo

im running a 3.33 pulley intercooled with cushman stage 1 NA cams through my auto making 425hp, im sure with the right cams and tune 450 should def be possible

2.97 Reichard Racing pulley is probably the smallest you will be able to get. It should get you to around 14-15psi with the S292HP cams. Those cams with 3.33 pulleys usually get around 450rwhp with a manual. With an auto and dropping down 3 pulley sizes I would say you would hit around 490rwhp with it.
