an interesting read i found:
Diy
yno
not something ill be doing anytime soon. but maybe for you hardcore guys with hptuners, this could be prosperous...
See some of the parts this thing requires?
Would need at least... 2 solid turned steel drums, about 16 inches in diameter and 16-20 inches wide... that alone would cost as much as all the tuning time on a dyno at a shop you'd ever want.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
well see the reason i posted this is because some people have connection and might be able to get the parts for little to nothing... just a thought.
