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 in their hand...

Even with that, our week was pretty awesome. Fastest diesel truck of the meet (almost fastest diesel of the week!!), and first vehicle on planet earth (needs verification) to crack 200mph on 100% vegetable oil!!

Will fill in details later, just getting back to town and starting to unpack. Feel free to check out @greenspeedresearch and @gsrfab on Instagram for more pics, if you're into that kind of thing.

Have data, will share. Our initial thought is our problem started from a bad relay controlling the Intercooler water pump, which stopped working during our 207 mph run (peaked at 209). This led intake temps to go from 120ish to 300 really quick and EGT to spike up. Took a very close look at everything after this and decided to make another run. Things got pretty western at that point.

Don't know how to upload pics from phone, will do that later today/tonight.
 
Exciting stuff! I'm really glad to see both of my favorite motorsports co-mingling and thriving together.
 
No build thread, we built it in 2011 and have just been improving gradually ever since.
 
I notice your sig says two different engines. Is that for different classes or what?
 
It's for two different fuels. 12V for 100% veg, common rail for bio-diesel and diesel. We got the rules changed to allow veg, but they don't allow bio for the record book, so we will have to run regular No 2 for that. Plan is to never run veg once we beat (IF we beat) the petro diesel record (215.091 for our class).
 
Here is the data from the most likely problematic run. If you don't have excel or some other spreadsheet program, "google sheets" or something will give you free spreadsheet access.

You can see where intake temp started rising sharply, peaking at about 300*F, which is MUCH higher than the typical 60-120 that we see. We believe this was due to a faulty connection on the intercooler ice water pump. Either on the relay or in the motor itself. It's also possible some debris got caught in there.

Engine ran a little rough after this run, so pulled things apart, did some leak down testing, adjusted valves, everything sounded good again so we went for another run. That's when carnage happened. Following post will have pics of that and other things from the week.

Never mind about uploading the data, apparently it's too big of a TEXT file to include...happy to email to anybody interested.

Also, here's some pics: too hard to resize everything for the forum, need better internet. Check out http://instagram.com/greenspeedresearch for pics for the time being. Carnage and time slips are up there.
 
Dang that is impressive! Congrats to you all on this year's accomplishments.
I'd say you've got some more than worthy "offerings to the God of speed" there..:Cheer:
