Just got 6 of the 395s on. A comparison of 16r20s to 395s. Lot easier to move around that's for sure. Hopefully will test on Monday or Tuesday to see performance gains.

I'm running a #27 button built by premco and the injectors to match at 10% overs. Warren from Premco said with my goals that this will keep the engine well within the safe zone. Im running 750 to 800 degrees egt in #6 cylinder. Going to smaller tires and the intercooler will drop temps even...

Nice build hethead! I know the intercooler can't hurt anything, only help. I took a more conservative approach on fuel but the larger injectors will help some, that's on the list soon.

Ordered 7 new 395s. All balanced with beadlocks. Going to be adding to the truck tomorrow. Should make a big difference with power, egts, less weight, and less wear and tear. Once project is done I'll post some videos of truck running and see what the performance gains are.

Installed the n14 intake with new hardware. Much lighter and easier to manuever, hooked the boost gauge back up. I also decided to hook the air compressor back up to the intake. Instead of pipe thread, Cummins changed it to -14ORB and then I got a 3/4" npt adapter to 1" barbed fitting. Ran a...

Im nominating CommoChief 1971 m35a2c.

Thank you everyone for the votes!!!!

I bet it came off a Ntc 290.

I just turboed my m925a1 and I used a bigcam aftercooler and crossover pipe. I saw 300 degree drops in egts and that's with the probe in cylinder 6. That's with no core in the aftercooler as well. I saw 12lbs of boost peak. With 12lbs there's not enough boost to cause big issues with intake...

I haven't called cummins directly. Alot on here say 200 to 210 is max. I haven't driven the truck since the pressure gauge installed yesterday due to the cold and crap on the roads. Im running a #27 fuel button. Pump rebuilt by premco. 10% over injectors arent installed yet. Even with...

The needle valve is a micro valve. It's not like a standard ball valve and lets only a tiny bit through. There could be some changes but it's designed to be very accurate. It also increases efficiency and safety. The valve can suppport 1500psi. It wont change the pumps pressure, the pump...

I just got done putting a turbo on the truck. Here's a clip of the truck running.

I did the fuel pressure gauge install today. Bought a 2 5/8" autometer gauge to match my other gauges. Gauge went to 400 psi. To match my other auotmeter gauges I had to pick 200 or 400. Decided if I do turn the fuel up and I was to get over 200 I wouldn't be able to monitor it with the...

I ordered the fuel pressure gauge and a needle valve. I'll use the 1/8" npt port on the solenoid. This way if I decide to up pressure I can do so safely. Im using pfte -4an line. Should have more photos soon.

I'm nominating my 1986 m925a1 cargo truck.

Put plugs in the intake where the original sensors went and used red rtv. Primed and used a self-etching primer. Followed up with using a high temp flat black paint. I also bought a pressure gauge to monitor fuel pressure with a needle valve. In case I decided to increase the fuel down...

Decided to go in a different direction. Decided that I want to run an intercooler. I was given the crossover pipe and aftercooler. I didnt want to buy a new core for the aftercooler. I Was concerned if I have a failure down the road, the coolant could dump into the engine causing a failure...

My 2 year old nephew came down to do a gift exchange and he wanted to take the "big truck" out. High of 10 degrees. Boost weather. Truck did great. At 2000rpms I saw 11 to 12lbs of boost. No issues.

If your heater has a small leak, You will want to get a new core sooner than later, when it decides to fail you'll have a nice clean up to take care of. Nice Truck!

Got the last set of armor lights installed and wired up. Bottom set comes on a switch. The top ones come on with the high beams. With just the fogs I have 8000+lumens, not including high beams or ditch lights. Each fog is an aircraft landing bulb. Not too shabby. I used lamin-x yellow tint...
