I started looking for a pulley set up for my crossfire. I did the search and according to HDDP all ASP kits and Renntech run the 178mm Pulley. LET has a 181mm pulley so my question is has anybody run this set up? Also does this set-up allow for use of the original belt? I know LET has 185 also but I don't want to go that route at this time.I spoke to Erick at LET and thought the 181 uses the origial belt.
Pulley break down 178 = 3 lb boost
181 = 5 lb boost
185 = 7 lb boost

Thanks,
Dave
