Had a great week at Bonneville!! Saw old friends, met new ones. Highly recommend all of you make an effort to check it out next year. Need more diesel heads!! Our journey ended rather abruptly on Wednesday afternoon when a course worker came driving up asking "is this yours?", with a WRIST PIN...

Howdy everybody! Just wanted to share the website for the team of senior design students we worked with over the last 6 months. They made us an engine dyno that is supposed to hold up to 2000hp (has yet to be tested due to some important "lessons learned" about drawing revisions...). Dave can...

Howdy all. With a little time on the hands since Bonneville got cancelled, figured I could post some shots of what we've been working on. This year, the plan was to take two engine (12V and CR). 12V for veg only and CR for petro and bio-diesel only. The "passenger side" of the turbo system...
