Richard Holderner Testing

Okay so Richard Holdener has had the itch to go ahead and start doing some really great testing on an L32 and L67 engine. Richard has access to an engine dyno out at Westech and has a pretty good reputation for really testing the limits of what motors can do in what he dubs as his “Big Bang” testing. He has done this with a 4.8 liter LS truck motor in the past and has had some crazy good numbers before the engine let go. Now he is slowly working towards doing this to a 3800 series 2/3 motor!

To kick things off though he is starting by collecting some data and answering questions and curiosities that he's had or that other people have asked before. Below are going to be a list of each of his videos and some of the main takeaways from them:
