Aside from the "super special" caterpillar BW turbo, I honestly don't know what the big deal is. I've read through pretty much all of his thread over on that forum and honestly there's really nothing there that no one hasn't tried before. Like everyone else I'm all for someone breaking new ground and giving them props when its due. Honestly I don't see whats so special. His attitude is well known among the respected members here, so there's no reason to go into that.
If you guys think his engine build is interesting enough to give kudos to then you'd fall out of your chair to see and read about a local farmers IDI build, and he did his almost 10 years ago. I've tried several times to get him on the forums to write about his build and share his technical knowledge but he's an older gentleman that really has no desire to use a computer. So all I can really say is its pretty bad @$$. He mounted a GT40R series garrett dual ball bearing turbo onto hand made manifolds. The engine ran on a considerable amount of propane, it spools up by 1800rpm and the heads don't lift off even at 32psi boost. The truck is a beast and when I asked him why he built it, he told me honestly he wanted a truck that could pull anything he needed it to and still be serviced without taking it to a mechanic.
Its guys like this old farmer that I respect, and appreciate their knowledge, especially when they are more than willing to help others out with ideas and tell them what has worked and what hasn't.
Honestly there's allot more thats been done to these IDI's than most of us will ever know simply because MANY of the great mechanical minds out there have no desire to use a computer or get on the internet.
i understand where you are coming from. theres several builders/vehicles that i try to lure to the boards on the internet to no avail.
the turbo is nothing special at all from what i got out of this, just cost effective for intended goals. the pump mods and cam combination etc put this past the norm in my eyes. i run a 6.5 in my ranger and fully intend to incorporate the things done in that area to my situation and am quite pleased with what i hear on those videos....sure as hell dont sound common for an idi to me.
If he will share the details with you why not write it down and post it here?
With his permission of course.
If he will allow pics that would be even better.
You should really take a pen and paper over there and ask the guy what he has done! That would be way cool. He might tell you and he might not but its still worth a try. And I am sure everyone would love to hear his story, even if it is told second hand.
Something wrong here... I still can't see anything. Most of the viedo is black. This may be a great build but... Not actually seeing something is not proving to me this is a working engine. It does sound great and I really want to actually see something. I'm not posting any longer on this topic...
We can send men to the moon! Heck, we might even be able to build an engine like NMB2 can, but one things for sure... We sure as heck can't ever get a clean, well shot NMB2 video!
i dont need video proof...if i was building this truck i would not post **** in the form of pictures most would want.... and no video...i dont have time for that ****. this guy dont have 5 kids or he wouldnt either
he would have to be young to care
i had guys call ******** on my rig etc....all i got for those guys was rack off if you dont believe it
to ***** about the video quality is crazy.
simply posting up the remembered formula to the ol boys build from 10 years ago is plenty for me....the specs on the pump in particular, or was the propane a cheap way of getting around pump technology? just post the notes on the subject...all i need to work with.
who waits till they are broke in?
depends on enviroment where its to live....for the most part they get broke like they are to be run...
Regardless of what happened before or the darkness of the video, I am going to give him the benefit of the doubt here, especially with Typ4's testimony about what's going on up there. I'm excited to hear more about it.
some sanity on the video thing
Oh yah , put this on me!!!
Actually I just spoke with him and they are going for another test run, Ken suggested to run it at low boost for a while to not over pressure the rings, as did HAstings. I can agree with that from using rings way over their design parameter.
I told him to watch the temps carefully , that is the most important in my book, and oil pressure obviously.
When I was working in Anchorage the diesel shop dyno operator ran any engine for 1 hour no or light load, when up to temp, 2 hours of low to full loads and everything in between, then 1/2 hr at full load. So that is kinda what I go by also.
i can understand this to a point.
but i would have temp and oil gauges present and bust this fawker hard since its not an extreme weather rig....it would be the fastest that b2 ever went down the freeway in its life if this thing is anything like it sounds...hell get a trailer that holds two b2's to really seat them rings..
one thing though....i would be saving for a richmond six speed....he is gonna destroy that zf if the numbers approach the goals.
mostly due to not having the mind of one supporting 5 piglets...it will be hard not to push the tires loose in 3 rd gear.
