There is nothing but stock diesel getting into those combustion chambers
Maybe I was near a large field of cows at the time
Anywho, keep in mind on the video that I was starting from a stop, then turning and accelerating...not starting from straight on.

I was going to go take a few more videos today (since I have updated a few things since then...different turbo compressor) but it got dark too quickly. The speedo is accurate within a few MPH over the given range...nothing substantial.
On flat ground I can put the car well past 100MPH without really having to try...just keeping an eye on that pyrometer

Now towing....thats another story
