If you use flow then how do you get the pressure ratio for the map... I didn't mention flow because we can't measure it so I guess I didn't mention it but I did calculate for it which is where I came up with the points I did. You need flow AND boost to mark a point on that map.

This was mainly to show how compression ratio and boost can manipulate different variables. Me and this other guy are tackling the flow variable you are talking about and will get something up eventually. Waiting on resources to show up in the mail... Guess I need to stop posting just parts of equations and get the entire picture into view. To be continued..

You mentioned not being able to donate every month.. It is completely 100% voluntary. Mike makes use with what he gets and adjusts the site accordingly. For instance, if we had a tonn of donations, we could get our own server and we wouldn't have some slowness that happens sometimes. Like everything else, you get what you pay for.. However, Mike sure makes every penny count. But yes, everything is voluntary. If you can donate, great, if not, being part of the site is great too.I will tell you guys right now, I have never given Mike a dime.. But, you guys know I have made tonnnnsss of videos and taken my truck apart just to show you guys things. I bought a junk P7100 and try to go out of my way to find the answers for you guys. Truth be told I went to college ever since a guy on the site named SASQUCH (or something) proved me entirely wrong and I said hmmmm, I'm sick of trying to assume things based on nothing. However, ignoring college and all that and just using the ppump and vids I make for you guys, I have probably spent $500-1000 because of things I broke, things I had to get, trips to town (which is 20 miles round trip) and even trips just doing absolutely nothing but driving for a hundred miles just to test mileage. So although I don't donate, I donate information, which I have thought to be a better "donation". Lately I have been buying tons of books on diesels. I just got one on turbos and head flow and just got a huge one coming on the thermodynamics specific to the internal combustion engine. I do learn from my stuff as well sometimes, so I do benefit from it to a degree. Plus I love double checking things I think I know to see if I am right or wrong. If I don't have a picture or something solid then I have learned to never assume I am right until I do. So to me you guys help me so I help you. I hate money so as long as my bills are paid, I will use the rest to help you all. So there you have it, my lame excuse for not supporting the site

I don't know what the big deal is about the crack. Mines had a crack across the windshield since I bought it. If the crack distracts you then I can't imagine what the windshield wipers do :lol:The interesting thing about driving the speed limit or even 5 under (like a lot of truckers do on I-70) is that people actually start dropping in behind you. I always think they are just waiting for the exit, but they stay there forever. People who drive slow seem very aware that a constant rate is a troublefree rate. If we all just drop behind each other and stay back a good amount like they all do, there is never an accident. Its nice because you never have to pass anyone, you just sit back an turn the radio up and enjoy yourself. Plus it is much easier to control a truck going slower than one going faster, you don't have to hold the steering wheel as tight, you can just drift along. I follow truckers all the time in my jeep lately. Not close enough to do any real drafting, maybe 100ft away. They drive nice and slow and even when they go up hills and go down to 10 under, I still stay behind them. You can get frustrated, floor it, pass them, now you just ruined any mileage you may have been getting.

I forgot about that, I see the same thing all the time, maybe even the same truck and trailer

try it now

I don't think it has anything to do with anything other than the overhead.

I have issues with the GPS because it is a satellite looking straight down at you so if per say you were going straight up, it would see that as no movement. I never see the elevation on it being all that great either so I am not sure how accurate it really is on a hilly road. I'm sure it is supposed to calculate for elevation changes but I'm just not convinced it's all that dead nuts. I don't know how accurate the markers on the interstate are but I would like to think those are the most accurate thing to go by.

Well theres a thought! Nice thinking diesel4life. No prob dripley, I think Mike answered it, I just didn't if they ever stuck open like that or not. I'm sure the engine was toast by the time they got it back

I wonder if something you are doing on installation of the tstat is shoving it open. Without a tstat the flow is so high I can never get over 120, as I said, but even with a tstat wide open it still has enough of a restriction to keep it from ever flowing that much. But the thermostats on these trucks don't just open, they open and close, constantly. With a trailer on a hill it might stay open but otherwise they should cycle. If yours doesn't cycle then it would just be cooling it the entire time, keeping the temperature lower. That's why I wonder if you are somehow installing it wrong or who knows what. Just seems to me that if it wasn't cycling it would give the exact symptoms you experience

Did you ever confirm the temp gauge was working accurately? Have you checked out the water pump? To be getting colder with each new thermostat is a little beyond me. Colder is more resistance though and a connection that is getting crappier and crappier would compound the problem, which sounds like what you are seeing.

Too much flow = too much cooling. Thermostat opening too much possibly. I took my thermostat out and it wouldn't get over 120. Same as wind chill..higher wind speed sucks the heat out of your face faster.

Yeah today. We've had some freak weather, lots of rain and now its 75F. Gonna head back to 30 in a few days but people already started mowing their lawns. It was probably taken pretty close to this.

I was driving at 65 and got passed by a new duramax ambulance doing like 80. It was puking white smoke that smelled like solid fuel. What is wrong with it? When the CR injectors fail, do they stick wide open or something? He musta been doing that for 30 miles.

Every time I go back to parents' I see this out my window which is a pic from yesterday. I can't see a damn thing in the city. I get to see the neighbors trees and house. Nothing in the city can beat the effects nature does on its own. I went to this cliff at the lake today. It takes 30 min of hiking up the side of a mountain to get to. I think it's worth it. You are 200ft over the lake.

Well it definitely has more power now. Half the trip back is a lot of short but steep hills that it always has issues with. This time it was able to go up them without losing as much speed. On the interstate I went from 70 to 80 going uphill in 5th which it usually couldn't do. I checked the oil this morning after running it a half hour yesterday and driving it 10 miles and the oil was so clean I could barely see it on the dipstick. Usually it is so black you could stand 10ft back and see it no prob We'll see how long it stays that way.

I got the oring fixed and took it back out and down the road 10 miles and drove into the garage and looked under it for 5 min waiting for a drip, nothing. Looked all over the engine and didn't see anything. I think it's good to go. I'll put it through the paces on the way back home, as usual Sure does idle a lot smoother. I watched a youtube of the same engine with "lifter knock" or something which made it sound like a diesel and mine didn't have that, it just sounded crappy overall. The valves all had buildup on them so I'm not sure how much they were sealing but I polished them up so they are shiny now. Seems to pur now. Hardest thing about it all....the valve cover, of all things. The thermostat housing kinda goes over it a little and the body goes over it a little at the other end so it was just a nightmare to get it in there and not have the gasket get torn up in the process. I wish it was individual like my 12v. Aside from that it was easy. I spent 3 days on it so how hard could it be at that pace

I had the upper radiator hose off and one end was a little spongy. I looked in it and I guess the inner layer had collapsed so it looked like a bubble of rubber inside it so there was probably very little coolant even going through it. That explains why it runs so hot, among other reasons. I got done but messed up an o ring and its leaking now so I gotta take the fuel rail back off and put an old o ring back in. They weren't bad but I had new ones so figured why not. It did start for a sec before I killed it so at least I know it still runs

The one with the puller on it. Marked I.O.D. Ignition Off Draw.

I got it hot plenty of times Think I just burned off the water and left the sludge. Apparently super tech doesn't have any of the detergents like rotella so once the sludge starts, it isn't going to clean it. Rosmella smells because of those detergents. It's almost done. I have been having to soak every single component in that carb cleaner crap and let it eat all the crap out. I power washed the head and doused it in penetrating oil so it looks brand new at this point. I polished up the valves and valve faces in the head and cleaned all the rockers/springs so they are all brand new looking as well. Gonna throw it all back together today and see what happens.

But you filter it.. I think this is a case of never changing the filter, never changing the oil, etc.

If that goes through, I would do EXTENSIVE testing on them before they could carry in the school. I went through my teachers just now and I would only trust 5 of them in the high school to carry a gun. They are only the ones who are truly on top of things, could spot a threat a mile away, questioned anything suspicious and followed through with keeping an eye on their suspicions. The other teachers are either too old or sleep or other stuff that makes them a bigger threat than a solution. Kids watch the teacher all day, its very easy to see every single thing they do, every single place their stuff is, I mean you can figure it out within the hour. If you have a gun, they will know about it. If you have a weakness, they will know about it. If you are old, it doesn't take a ph.d to figure out who is weaker... This means there needs to be a common sense test based on all teachers' input. The 5 teachers I picked would probably get a unanimous vote from every other staff in the school. These 5 people should then be the leaders of all other gun decisions because truthfully, I don't think the other teachers would have a clue, if they did then they posed other threats such as depression or sleeping during class (so kid could walk up and take the gun) or other things you noticed about them that wasn't quite right. Juniors and Seniors could also be a big help because they have seen who has their stuff together and who doesn't. I don't think teachers who only see each other when they put their smiley face on (at lunch), really know the true side of each other. Students who spend alllll day every day will know. Common sense tells you which students are telling the truth and which ones have it out for a teacher who gave them an F. It's very complex and delicate. But I do think there are at least 1 or 2 individuals in every school staff who could carry a gun and would prevent mass shootings or at least be there with only a few shots fired. A metal detector would go a long way (my school didn't have any, even to this day).

I've been researching this for some time now and found many culprits but it seems a lot of the common results boil down to crappy oil that doesn't hold the contaminants so they just "fall" out of the oil and build up on everything. Low detergent oil like super tech crap probably falls under this category. My brother said rosmella is highly detergent and will clean any of the crap I don't get up. I power washed the head and watched chunks of the crap fly off. Then blew it all dry and now letting everything I can get off (rockers, valves, everything) soak in that carb cleaner stuff. I have new gaskets and o rings and stuff for everything so I hope I don't get too many leaks if this rotella crap does clean all the carbon off and expose worn out seals that I didn't change. We'll see. I'm gonna do nothing but let stuff soak all day long.

The starwheel usually barely lets have any fuel at all until you have 5psi. I can see under the right circumstances you could get it to smoke for a sec. Not sure how valves could do it unless they were way off.

I had to chip it away to get to mine as well. Mine wasn't that bad though I mean it runs like a top. How do you get rid of the crap? I can clean the head but the top of the lifters and around there I can just scrape off until its just a light "coating" of the crap.
