I was in the zone of 2 -8 psi boost with my stock PCM and vac wastegate until about z week ago. Turbo stopped whistling, guage showed 3psi max under load on a hill. I run an electric vac pump and today found it was running about 80% of the time Pinching off lines until it built vac and stopped...

Just dont bump a fan blade with that stethoscope! Lol. You find yourself 15 min later waking up on the fender with ptsd.

Super easy to swap. Open the turbo. Remove nut on end. (Possibly reverse thread - cant recall) Heat old wheel gently with a propane torch and it slips off. Heat the new wheel and slide it on. Tighten nut with a rag over the vanes to help hold it without tearing your hand up. Reassemble the turbo...

My buddy always used to shrug at noises and say "that just means its working ". Lol. He was not a good mechanic. Ive got a stethoscope with a rod on it and an extension that does the screwdriver trick with finesse. From my local parts store. Eliminates noise thats ambient and bouncing around...

Im fooling with boost right now by completely shutting down my turbo and logging some data. I like what you're up to. Id almost utilize it in reverse to shut the turbo down on the hills (your way is better to detune it) as thats what causes my really hot intake temps (170 deg) and EGT (1300...

My valve cover leaks a bit but I'm putting it off as I fear the bungle of pipes and fittings crammed in that 4" circle. You guys are my heros. Lol

Awesome. I love where this developed!

Just following this for a while now and browsing the web. Does it make the power in a similar rpm curve as a 6.5 or is it a higher spinning engine?

Exhaust temp (max im guessing)is stated in the specs as just over 1200 deg. Interesting. Thanks guy. Very cool.

I could go measure my pulleys - but do you know off hand what speed our pump/fans spin at? Are the a 1:1 of engine speed or different?

Its all covered but I will add clutch, clutch, clutch! I too did all the upgrades, thermostats, balanced flow pump, fresh rad and new Severe duty hayden clutch - still had high temps. It was the fan clutch. Almost refused to engage from new. Returned it for another - same thing. I got the...

What secret proprietary item is under the coffee filter?

Great!. What are you at for costs so far? Roughly. Im on a similar track for my hummer and pricing out my options. Pusher bus hydraulic fan drive us where im headed I believe. Keenly following this.

Intercooler. Sweet. Never had a runaway yet. Except for a PMD revup. I get the feeling its mostly bad news from here...

Propane is 11 dollars for a 30 pound tank at costco. LOL I can't resist starting a cascade of vehement opinions and arguments. Im propane neutral by the way. Switzerland of propane opinions.

You mean pushing a house is not equal to pushing a honda civic at 60mph?Lol. Im just trying to guage if it would return 15 mpg in a 7200lb beast or be a nice tiny engine in a massive engine bay getting 20mpg with the same performance as a 6.5TD. Ive been watching cummins 4BTs for a while but the...

Whats your Colorado weigh?

What do you think that would be in a 1 Ton....

Its power specs almost match a TD 6.5 for torque and HP. It would make a great swap engine for a H1....
