I would be interested in an 80mm also. I have a brand new never used 84 and don't know what to do. Could you do a partial trade on a 80 or 77? Thanks

I've been wanting to upgrade to the 77mm for a while now. Was going to go clutchless, but from all the research it seems like no one has gotten the tune right for them. From what I've learned BIP came the closest and I almost pulled the trigger on it but BIP doesn't do high performance work anymore. Just want some info on this pulley and tune, that'd if you do tuning as well. I don't want to trade power for driveability/reliability.

The new UPD 77mm SC clutch style pulley is a breakthrough in power and performance for the M113K engines. We are now able to reach new power levels with an easy SC pulley change and still retain the clutch SC pulley feature.
Incorporates a custom duel bearing design, special tight tolerance thrust bearing to handle more power, rpm and increase clutch engagement.
Only 2.25 lbs VS OEM at over 3lbs
This will equal to a 180mm crank pulley.
Beltwrap kit is recommended.
Price is 695 plus shipping
