Question about repowering early PT's

[David Brady]

True, but they pollute, they're maintenance intensive, they're fuel

hogs, they run backwards (maybe this is a feature), and they've

been evolved to the limits of their engineering (o-ring cylinder
sleeves,

for example). They had a good run, now it's the 4-strokers turn.

(Actually has been for many years).

The 8V92 is sheer genius and Ibelieve the highest development of
the 2-cycle diesel power plant. Last I heard froma captain I know in
the Coast Guard, they are still manufactured for marine use. Power to
weight ratio is exceptional. I loved mine in the '86 Newell, just had
to checkand oil more frequently. Acceleration and torque upgrades
was not quitecarlike but at 475hp, a lot more nimble than my 525 hp
now.

The biggest benefit of the 4 stroke Series
60 is mpg. The second

biggest benefit is service and parts (these engines are still being

manufactured). The third biggest benefit is DDEC IV control. The

fourth is emissions.



Most owners get around 7 mpg. This could be as much as a 40% increase

over the 8V92. An engine is probably going to cast $25K to $30K,

and the conversion another $10K to $15K. To recoup $50K will take,

hmmm: (at $5/gal), 175,000 miles. Clearly one wouldn't do this to save

money. But diggity-dank I sure would love to own an '86 PT40 with

a Series-60.

Well, I have an 8v92 and it has served me well. It would be
nice I guess to have a 60 Series but haven't determined why. Talking
points perhaps. A 60 is to tall to fit in my coach without major mods
to make it work. Just buy one with it in there if that is what you
want.

I look at it this way. These things aren't race cars, you buy them to
full time and/or travel and have fun. If you are in a hurry you don't
need one.

Just curious....has anyone ever considered or pursued
re-powering some of

the early 80's PT's (82-85) from the 6V92 to an 8V92 or something else

(Cummins? Cat?). I really have NO CLUE as to the viability of such an
idea.

But, the discussion about one the early PT's for sale brought out a
comment

that one of the owners felt like they were a bit underpowered going up

hills. I was just wondering how hard it would be to upgrade the
powertrain

so that they got more power.



Along the same vein, I know that some diesels can have their ECU

reprogrammed to put out more power and generally the limiting factor is


what the transmission can handle. I know that these 6V's aren't really

computer controlled so that may not be an option in this case. But, is

there something else that could be done to bump up their performance?



Anyhow, as a wannabee (who won't be til he gets a job and sells some
land),

I've been looking at all models of the PT's and just looking a all the

options that might be out there.
