my current set up is a 8rib, secondary drive a&a ysi 3.125 razr cut pulley making 15psi.
I tried a regular smooth 2.75 vortech pulley and upper sweep it made max 15psi from slip.
I guess I am left with 2 options, I already purchased the new 2.70 razr cut 8 rib from A&A and it is shipped (being dropped shipped to carbonite racing for the coating Thursday delivery per tracking #)
I could just send carbonite my regular smooth vortech 2.75 pulley and have it coated since I prepaid for the coating already. and try both a smooth pulley with carbonite, then just the regular razr cut 2.70 pulley.
I spoke with carbonite racing in a lengthy phone call, they have done a lot of razr cut pulleys he has said. but when I search I don't find much feedback on the carbonite coating other then a couple on regular pulleys.
my overall thought was with both razr cut and carbonite coating would help eliminate any possible slip, but my luck nothing will work like it should. everyone seems against the idea. I should have just went 10rib and called it done. lol

I hear the cut pulleys eat belts however I've never tried them myself maybe some who used them will come in now with an 8 rib I use e little VHT and works great.

2.7" razor cut pulley, no issues. Been on there for awhile now. Same belt, no issues.

I have ran the YSI with the 3.0 and 2.70” on A&A 8 rib. With the Gates rpm belt get no slip, now that I’m raving just over 7500 I went back to a 3.0”. The 2.70 didn’t pick up any noticeable power on this combo.

Just put together a nasty 402 YSI 2.7 build together. No issues on the 8 rib.
On my last Novi 2500 with a 2.75, no slip either on an 8 rib.
