Good job! Congrats!

 

Yesterday I finally got to take her out to stretch her legs. After a winter hibernation and some lung surgery AKA turbo work I’m happy to say that damn… I can hardly wait to hook up my trailer and see how she pulls.

Didn’t run FORScan since it was a spur of the moment shakedown/ fuel up run.

I can say it is way more responsive to throttle input with the new turbine wheel. 1400rpm and seeing 6-8lbs boost, lights quickly and saw 28lbs ish as it goes through the gears and I quickly ran out of road ( 1 mile between stop signs) with excessive speed. EGT is down as well 900°ish. I say “ish” on both because I was mostly watching the road with glances at the gauges.

SDK 65 DD was the tune I was running.

First test for me will be in 3 weeks when I put the 8500lb rolling hotel on the bumper and put her to work. Local 5 night camping trip within an hour of the house as a shakedown for the truck and trailer.

Next trip is in May down south i5- 405- i90- i82 so snoqualmie pass and the i82 up out of Ellensburg are both good uphill tests. Should be able to wave to @BWST Jeff as we roll past Lake Stevens.

 

Hooked up to the trailer today.

Pulls nicely with this wheel combo. Power is more lineal now and starts to come on earlier in the RPM.

Flat ground pulling so far. No real hills to fully put it to the test yet but I’m happy with how it’s working. Boost is up, EGT is down. 26lbs and 1075° in a 65hp tow tune.

FPG shows 60lbs at idle and dropped as low as 48lbs during hard acceleration so time to do the fuel filter.

 

I scrolled back a ways but didn’t find it. What turbo combination are you running? I assume it’s the Riffraff wheel with KC turbine?

Glad you’re liking it so far. The invitation is open if you would like to add your “review” to the Turbo Matrix once you get the towing miles under your belt.

 

l

Second generation Wicked Wheel so a 5-5 wheel and the KC 300 turbine wheel and a fresh 360° rebuild.

Super low miles on the WW or I would have done the balanced assembly. It was installed when I had a bunch of work $$$ done few years back.

That’s when I realized I needed to not be intimidated by the 7.3 diesel.

 

Nice!

Sounds like so far the turbine alone (added to the previously installed WW) has made a significant difference. That’s great!

 

First true test yesterday on the new turbo combination with some mountain pass hills.

Between Snoqualmie Pass i90 and Manastash Ridge i82 I can now say I’m officially done mucking around under the hood. At least for now.

It’s been 5 years since I’ve done this trip so my brain is a little fuzzy on past performance but I will say that my truck in its current configuration has arrived.

Next trip up through the Fraser Canyon will be a fresher comparison.

Never once did I drive by EGT and was only limited by boost and speed limit.

SDK had told me they prevent defuelling by opening up the 24lb window on the MAP to 45 seconds. To prevent a soft code cel I’d drop it down a little bit periodically on the looongg uphill pulls.

All day long at 5-8 lbs on the flat @6-800° ish. Briefly saw the EGT kiss 1200° on the Snoqualmie, after passing Pokey Joe, with 28lbs on the boost.

I can’t say enough about the KC 300 turbine wheel and how much it has improved the drivability and performance of my “ healthy running 125k mile “ truck. 205,000 Km on the odo.

Disclaimer: results may differ based on current state
of test subject vehicle.

Jeff @BWST yesterday had questioned me about EGT. If I had to drive by that gauge. Not at all.

A few years back I did briefly load a PHP file and found that it ran hotter than my SDK file. I feel that had I been running a PHP file yesterday my results would be different.



At a dog pee stop along the way.

 

With my aftermarket ECT gauge on average I’m seeing 170-180°.

It will climb above and have seen it upwards of 215° when the clutch fan engages and pulls it back down.

I haven’t hooked up to FORScan to see what value is given there.

Not sure if the motor is running on the colder side or if the gauge is. By the fan engagement I’m leaning towards the gauge being correct.

Recently did the Waterpump, Thermostat, and ELC with no change to temps. I had thought I’d see a climb in operating temperature with the new thermostat. Will have to go back into the receipt folder and find the part # to reference the opening value of new thermostat.

I had always suspected that the old thermostat wasn’t closing properly.



For reference here is the sending unit location.

Is there a better location for the sending unit placement for ECT?

 

Yesterday was oil change day. Today was fuel filter day.

July 2021 I did a complete rebuild on the fuel bowl.

2021 clean as a whistle after the rebuild.

3 years 6000miles and what the heck is all that sludge from?

Cleaned her out again rags, shopvac, small screwdriver for the tight bits.

It’s alive. Idles at 62psi now up from 58. Haven’t driven yet to see where it drops to but was seeing high 40’s on the last trip.

 

Well that's not a fun thing to find. Glad you did!

Do you have a pre-pump fuel filter?

 

Yes, the WIX 33972 filter as recommended by SSJ.

Climbed underneath to take a look and for the most part it’s pretty clean. It was sucking air though and was quickly fixed by snugging up the clamps.

 

Just checked the receipt for the new thermostat. 192°. Seems strange that on average I’m running about 170-180°. At least it’s not overheating, but I read somewhere that the diesels run more efficiently on the warmer side.

 

IIRC, from my very dependable Internet wiki

they should be running between 200-210 for best performance.

with clean ELC, that should be very easy to do
I bought the RiffRaff 202* stat for my truck

 

Just got home from the property today.

First rest stop and smelled diesel. First time in 20 years with this truck.

Climbed under the hood and found the new NAPA fuel filter o-ring is seeping. Tried to snug it down a bit more but it continues to leak. Gonna change out the filter anyhow. Old filter and was seeing 58 at idle and dropping to 48 on mashed pedal. This one here 52 at idle, down to 40 on steep grades.



At idle. 400 miles on this filter with a small leak.

Have to do a boost leak check as well. Down a few lbs from my last trip.

 

Last trip towing the trailer boost was off slightly so I did some investigating.

Leak in the intercooler on the bottom tube. The previous owner had an aftermarket Transmission cooler installed and the hose clamp rubbed a hole.

Took me 2 hrs to have the intercooler on the floor.



That might bleed off some boost.


Dropped it off at a radiator shop for a spa treatment and repair. $117.00 they washed, flushed, fixed and pressure tested.

Second leak is in my boost gauge line up in the pillar, so that will be replaced next.
