Hahahaha I dont know much about them at all...i met one guy a while back..shane was his name...said he worked with them...every once in a while i go down there to morgans corner and watch those truck pulls, but i cant say its too terribly exciting...im not trying to step on anyones toes here...i can imagine the excitement of building your own and running it. Twisted diesel is about 10 min from the house. Ive heard good and bad about them but they still havent touched mine.
