I run in cotpc. I did not realize you were talking about bushed woorly gigs because I thought I seen somewhere back through this post you said you were running cotpc. I can understand takin a 3.2 or 3.4 and putting a bushing in and getting 900+ and maybe some are doing that with same chargers with modified housings and wheels. T.S. rules state that the wheel must protude into the bore an 1/8 inch. My $.02 is if your wheel protrudes an 1/8 and your making over 750 to 800 you are in the 1 percentile and thats at the CRANK. Take it for what it's worth because $.02 doesn't buy much. I for one love to see the big bad and ugly show up to the pull because you are always garaunteed a good show. I,m swithing brands*nx*. peace ouchttt
