Engine/Transmission (1998.5 - 2002) does a new turbo require a break in

[Brand-X]

Ok I could not resist the sale price and free shipping so I bought a sps 62/14 a new HTT manifold and some mach 4s like the title says does a new turbo require a break in' thanks again for the info. This site rocks even if it puts expensive thoughts in my head :-laf

No break in as such, when i got mine i took it easy for the first 15 min or so to make sure everything was oiled real good. I didn't max the boost out for the first 50 miles either, maybe a little overkill but that's the way i did it.

Just make shure you preload it with oil before installing the oil supply line & start the engine, let it idle for 5 min. to get the air out before spooling it up!!!!

There are 2 different theories I will not post which large shop says what.

One very well respected shop says go easy for a couple hundred miles or so.

The other says go ahead and treat it normal after initial startup oiling.



I always tend to let them break in for a little extra insurance.

no break-in required...



fill the center with oil... turn the shaft on overflow and fill some more... button it up, fire it up, go for a cruise... by the time the truck gets up to temp, the turbo is broken in. romp on it!

PDR said to get a couple hundred miles on it before towing. SNOKING

 

[Forrest Nearing]

it doesn't really matter... it's a simple shaft and bushing... it's designed to turn at 150,000rpm... if you put a couple hundred miles on it or if you head out w/ 20,000lbs in tow, it'll either get broken in in a couple hundred miles, or it'll get broken in in 20 miles

So is a cam. So is a crankshaft etc. etc.....

Those usually last better with a gradual break in also. IMO

crankshaft turns maybe 5,000rpm tops in most 5. 9CTD applications... cam turns twice that...



turbo turns 30 times that... so if they say to break in the cam for 10 minutes, thirty times that is 25hrs... I don't know about you, but it takes me a lot longer than 25hrs to travel 200 miles!



granted, you won't be spinning the turbine at max speed right off the bat... if you went off of revolutions, it'd probably take you a couple years to "break in" a turbo



I speak from experience when I say this: I had my buddy at Majestic in Irving, TX build me an HX40 back in the day... I asked him what kind of break in... he said no worries... we tore it apart a few weeks later and he said everything looked normal... we put new bushings in it and tore it down a few weeks later... it looked the same...



a turbine shaft moves so fast, if there's a problem, it'll rear its head pretty quick!

 

[Forrest Nearing]

now, if you've got a turbo company that's "requiring" a particular "break in" time, follow it! (even though they have NO way of proving it)



might as well cover your bases!

I tell all my customers to be nice to them fo rthe first 100 miles or so. I also prelube them with Amsoil before install. I know, I know, to each there own. I just like to play safe with $1400-$5000 turbos.



Not Bashing anyone here, but even on journal bearings there are some wear in requirements. When I was a Millwright we always had to start compressors in stages. Run for 30 seconds, 1 minute, 5 minutes, 10, 20, 30, 45, 60, 2hrs, 6 hrs, 12hrs to insure the bearings didn't heat up from being too tight or cockeyed. And they spun at like 300rpms.

All well and good, except the cam turns at 1/2 engine RPM, not twice. Which really just changes your 30 to 60 times.

I'm retarded...
