JAmmer 5s kick ass i know of a pretty crazy '99 with em...
They are like 8x.011-12ish... Diesel Dynamics wouldn't tell me, but i looked at them under a magnifying scope and that's what they look like, very nice EDM..
they made 582HP with a drag comp and 66mm charger. They make excellent power but run a little hotter and are bit smokey. For the money they are the best bang for the buck.
