Wes, you've got me hooked. I just spent a few hours re-reading this entire thread. I've been away for a while and it's nice to see that you have committed yourself to developing freakish power levels for the old International IDI. I'm glad you're now making a living bringing your expertise to this platform. A lot has happened since I've been away (long story, I'll post a thread about it in a couple of weeks) but I will soon be back in the IDI game and I know who I will be contacting for go-fast moar power parts. Thanks for taking the time to document and share the work you've put in to exploring the limits of this old (but great) diesel engine, it makes this board a great place to hang out.
