I've heard now of a 2.60. Man, how low will they go!
What's next a 2.50 in our future. Where do we draw the line.

2.60 Pulley-Bid 2.50 Anyone

Trey, are you at all concerned about overspinning the blower at this point, even though it is ported? I'm just wondering where the positive power/torque return ends now.
We just figure its like adding a 2lb lower albeit cheaper. Gonna have about a pound or a tad more of boost now whether it will make any more power not sure but TQ will be up especially under the curve . He is going to have his blower ported soon so we will have some good comparisons!
2.93 is all you need 
I don't think there is enough surface area with the 2.76 to prevent belt slip on a regular basis nevermind a 2.5 or 2.6. A wiser move would be to install a larger lower pulley.
what's the point of a super small upper? why not get a 2.76 upper and 8lb lower combo? If all you're trying to do is overspin the blower, you might as well go all out.
John JLP has a 2.70 upper that you can run without milling the snout. We will test it and if it works great if not we will make it a paperweight. After the whole ordeal we have went through wtih RR trying to get the damn products it would be nice to see a worthwhile gain!
Thanks for the info Trey.

according to jim once you get to 2.73 it rubs the snout,anything smaller you need to lathe the snout down some.i think your ok because your using a jlp 2.7 correct?? he has his setup where you don't need to mill the snout down is my understanding.
because i'am not trying for that much boost.my goal is to be around 15-15.25lbs boost with my current setup using just a upper pulley because i don't want the hassle of doing a upper/lower setup plus 15lbs is not really overspinning the eaton to terribly bad to create so much unwanted heat.
wuplash - I am using a 2.80 pulley. I was just wondering about the milling. But I am not sure why you would want to do that? The reason people go with an upper pulley is because it is cheap and easy to put on. You can easily go back to stock. But now that you would have to mill the shaft for a 2.6 upper pulley, I just think it goes against the whole point of an upper pulley. But then again, if you don't care about going back to stock then who cares, go for it!
It is still cheaper then adding a lower pulley so I guess its just personal preference. It will be interesting to see how the 2.6 performs. It should perform like a 2.80/2lb lower, but wether or not the belt can grip it enough will be the issue.
Good luck with the pulley wuplash, I can't wait to see some pics/track times :rockon:
