Ok, time to explain this. Listen up!
First, this is only records set at the Bonneville Salt Flats, not any other kind, not international, etc. (http://www.scta-bni.org/
Second, there is no longer an E/BMS class, it is E/BGMS.
E = Engine size, 184-260 cid (3.01 to 4.26 liters)
BGMS = Blown Modified Gas Sports class
This record is for GT class cars, modified, with blown engines of 3-4L.
Here are the current records, with the JUN entry highlighted:
Blown Gas Modified Sports - /BGMS
AA Bonner's Bad Berkley B. Denton ' 02 254.135

G Richard Kreines Jim Steck 8/06 217.152
H Fairhill Millennium Falcon T. Stephens ' 00 205.207
I Fairhill Millennium Falcon T. Stephens ' 01 146.981
So yes, that is **** fast, but it is a limited scope record. The good news is that the record is relatively old compared to the rest of the records. 2007 was a good year for breaking them.
