~ PART#49 in a project dubbed "Nanuuq" to swap out my lifted Land Rover Discovery 2's blown 4.0L V8 & boring ZF auto for a Cummins 4BT 3.9L turbo (Holset Super HX30W) diesel 4-cylinder engine (Bosch P7100 pump) with an NV4500 5-speed manual transmission. The AWD 4x4 will remain with the LT230 transfer case divorced behind it all, & plenty of Dodge 6BT parts too. Another big phase of my custom DIY build to create a do-just-about-anything off-road / overland rig. Did I mention it's a camper too?

Lots of near full-throttle rips in this one as I test the new gauge array & start pushing the 4BT a bit. Great oil pressure, coolant

@jamescunliffe9872 3 года назад

I still think you need a longer exhaust and slight tapering constriction,using a rifle as an example,if the barrel is cut off gasses will exit fast but pressure duration time becomes lost? You should see a gradual rise in the boost curve longer duration and diminishing slope after full pressure instead of a sharp spike that's better suited to high revving petrol engines!:)

@Tinker1837 3 года назад

@@jamescunliffe9872 It will get a full exhaust eventually, even if just for reducing the fumes that sneak in the cabin with windows down. But wouldn't in that example the end of the barrel be like the end of the turbine blades? As in after the blades the heat energy would have little effect aside from the scavenging effects of having a longer pipe, but I think even scavenging isn't useful until pretty high power levels. Not an expert by any means, but you do have me curious about it! (going to have to do some reading up on this later)

@nickmccollum5836 3 года назад

Seems a bit lethargic. EGT numbers are very low... You can get up to 1200F. Boost pressure means nothing to a diesel, you can stick 100psi in and still make no power. Check your timing and fuel screws. Your EGTs should come up MUCH faster.

@Tinker1837 3 года назад

That may just be a combination of me being careful & super low 1st gear & the 34F temps. I for sure need to do some more tuning now that I have the gauges to see what's happening. Still blows me away how cool these things run! At idle it doesn't even register on the EGT gauge & I confirmed it's accurate with a laser temp gun + I can put my hand easily right on the manifold... bonkers!

@Tinker1837 3 года назад

70mph = 2050rpm

That's perfect. I was concerned it wouldn't due to the low rpm of the Cummins. I think the 35s off set the loss in rpm nicely

@Tinker1837 3 года назад

Right! The 3.5:1 axle gears + big tires are a lucky match to the 4BT's low revs.

You'll have to do a max speed test. I can't remember if you left the stock Gov springs. But if the governor is 2700. You're looking at close to 90mph. Too fast for disco anyways... lol I wouldn't ride the governor past 2300 for extended periods anyways.

@uhmlmfao 3 года назад

If you went with an NV4500, if I’m not mistaken, that sensor is for reverse. At least my nv5600 I swapped into my 6.7 is what it’s for. As far as RPM, typically is read off the Harmonic balancer/ crank position sensor. But I’m speaking without going back on your other videos so I don’t remember if that was addressed or not. My opinion on getting proper speedo, would be to see if you have a speed sensor on the tail housing on the t case or rear diff housing maybe? Idk man, but loving the project as spoken countless times. Just posting my .02

@Tinker1837 3 года назад
