i have the cross country top mount and it does work well, the lads at cross country are also a good bunch.

Such nice guys. I thought they had forgotten about me but they didn't. Really excited for it and kind of glad I didn't have to make one. We were getting ready for that....
 
Sorry to highjack Chris.

Are you running a stock turbo? Do you know your EGTs?
Grunter G Turbo. 20 PSI. I see 1250 occasionally but it levels out to 1150. We don't have the big inclines in FL but up to TN it didn't go over(alarm set for 1260). 900-950 cruising at 70-75. I want to make sure when this truck goes out West next summer that we're good for big inclines. Real mountains.

Also....the Nomad valve body with the 3rd gear lockup seemed to really help things out with EGTs. BIG change with that valve body in the truck.

Cross Country says a 100* Celsius drop can be expected. So I'm hoping to see maybe 1000 or so really on it. Might bump the boost up to 23.....or wherever the Grunter will go. We'll see.
 
on my 12HT I can't get it over about 925F with 20psi on steep climbs, this is with 30% larger injectors, and front mount. I feel like I can still get more power out of the 20psi but seems the only way would be a injection pump rebuild with bigger plungers like they do down under. would love to find someone in North America/Canada that can do this too, would save a bunch on shipping

Not too bad. The ultimate test for any boosted cooling system is long hauls, under boost, up long inclines. The interstates and highways in the Rockies are brutal on vehicles cooling systems. In the US, I've seen never seen as many vehicles on the side of the road as that area.
 
I've also been thinking of a cabin heater for the past month or so. Haven't come up with a plan yet, checking out all the options. There is a pretty compact propane heater that would be neat that you could mount to the side of the camper, but you would need a way in for the propane hose and where to mount the propane tank, and have a combustion inlet/outlet. There is also a Propane heater that is designed to be mounted outside/under the vehicle, but you would still need to make holes for the heated air to come into the bed/tent. I am also interested in the Espar air heater, since I already have a Espar coolant heater. But same problem, would need to make holes in the bed/cap for the fuel line and combustion inlet/outlet (burner air and exhaust). I think I just have to admit that I will need to make some holes no matter what route I take.
Are you planning on putting your heater outside and make a hole for the heated air to enter the bed/tent?

stock turbo at 15 psi. pin grind and tweak of the main fuel screw. G turbo one day...

its hilly around here, low down torque is great, theres a long steep hill where you would drop down to third at the top, now i can do a steady 50 mph in fifth all the way up.

i back off a little at 1300f, only reach that on the longer, foot to the floor ascents. im not constantly driving on the EGT gauge.

I'm going to keep the box under the truck, run the duct up into the tent thru one of the flaps(16' expandable duct). It's very very quiet....maybe a little tick out of the injector and a whisper out of the exhaust. If I did a lot of super cold weather camping, I would probably have a dedicated flap or port stitched into the tent....pass the hose thru that. I'm not sure how I will run the hose in the tent or what side. It's a big puzzle to get in my tent......close the awning a little, hoist the dog up in back opening while standing on the tail gate, put the awning back(if it's out), I go up on the passenger side on the ladder thru the side entrance. Maybe it would be best to close the awning at night....or at least fold it back. Then put the heater on the driver side. We'll see. Looks like mid 30s next week for our trip so I think I'll be able to use it.

Don't propane heaters create moisture? Thought I was reading that somewhere. Apparently the diesel set is very dry....no moisture.
 
Hey @chapel gate.......check out the before and after on that FT we got from you a while back.

That is a thing of beauty! I don't think I'd have the patience to get an old engine looking that good.

It helps to have all the right equipment to do it. I bet we've cut down the time to do this stuff by 75%. It's become oddly relaxing....huge amount of satisfaction to bring that stuff back to new, if not better. I have a whole list of motors in the shop that are going to get the same treatment at some point :)
 
Our TN trip was a good time.....cold......but a good time. The diesel heater was great. It was nice waking up in a dry tent without moisture. Sucked down some fuel(I am running a very small diesel tank for it) but otherwise, it was great. I think one night I ran it for 16 hours....part of the time in the canopy for the dog while we were sitting around the campfire, then moved it up to the tent. I am going to carry a small transfer pump I think so I can siphon out of the main tank.....eventually when I do a second tank, I'll plumb it for the heater OR a petcock/drain so I can just transfer into the heaters tank. On a lower setting and maybe 8 hours a night, I could get 2 nights out of it. I ran it pretty warm.....I have Florida blood......very thin.🥶🥶

Truck did great....17.4 mpgs were my best of this trip.

Next up....Eaton lockers front and rear. The lunchbox in the rear has got to go.

Night 2 we camped on an overlook....about 3300 ft high. Was windy but not as cold as the night before....maybe mid 30s. Great view up there....pretty cool drive up to the top too.

Night 3 was back down in a valley.....neat spot. Quiet. I think hunting season had just opened up....and with it being a holiday weekend, I think it was a pretty busy weekend in this area. The amount of trash left by the hunters was hard to believe. Enough trash at the campsites that we weren't sure if people were coming back or not. Hard to believe.

Any kind of efficiency idea on the heater? Gallons per hour, etc.?

Gorgeous truck. I love how this truck gets used, modded, used, modded...

So the second night I ran the heater for about 12 hours. I was really trying to run it as much as possible to see how much it would burn. The tank is 5L which is 1.3 gallons. When I filled up, it took .67 gallons I think. My fuel pickup is pretty low in the tank.....so I think if I used it a little less, I could get 2 nights out of it pretty easily. I didn't have it too cranked up.....maybe 50%(you can select how much the fuel pump runs.....1.7hertz to 5.5hertz....I kept mine at 2.4). I bet with 2 gallons(tank that can with it was 10L....too big for my setup) and moderate use it would last 4-5 days easy.

It's not super warm by any stretch....I wish I had a thermometer in the tent to see what the temp was inside....I'm guessing mid 60s....not bad when it's 30 or so outside. I've been in FL for 25 years....on about day 2 of living in FL, your blood is thinned out.....so 60 degrees is damn near freezing in my book :) I think if I was really doing some longer winter camping, I'd insulate my tent....insulation combined with the little heater would be really nice. As it is, that tent is an aluminum shell with some carpet and heavy nylon walls. Not ideal.

I found on the 3rd night that the smart move was to put the duct under the cover I was under......that kept me very warm. Too warm actually but easy to modulate. All in all, not a bad piece to have.

Soon I'll run out of mods on this truck I think :)
