RE: I found the weakness of the Challenger
I was concerned with the halfshaft, but it should have held up to the mods choodock has.
Steve from RDP is flying in from Australia tomorrow. I know RDP has 3 options right now. 600HP, 1000HP and 1500HP. I will talk with him about costs and let you know what he says.
I posted about it being the last weak link about a month ago. Good memory Chris.
