Default Cat 3208 turbo boost pressure

I currently have a 1980 bluebird with a newer cat 3208 turbocharged. I can only draw 5 in/lb of turbo pressure at maximum effort. Should my turbo have a wastegate and shouldn't I be able to gain better turbo performance? The bus runs great but is woooofully lacking on hills even with the turbo.

Glad I joined this Forum, was going to KC tomarrow to look a 88 or 81 BB FC at a insurance sale, was planning on pulling a 32' trailer with a jeep and ATVs to Utah this summer, but didnt realize 3208 are not very powerful engines...

There is nothing at all wrong with the power of a 3208 turbo in the 88 FC. Mine will run 75 all day long. I don't know about the 81 though.

Power in the flat lands ain't the same as power on the grades. The 3208 will only stand 15 lb of boost. Contemperary 6 cyl diesels can handle as much as 30 lbs. That makes a huge difference in grade climbing ability.
I have done more to squeeze power out of a 3208 than most folks would believe. John and Randy are well aware of my efforts to maximize the out put in both my kitty Cat powered rigs. My FC will do 80 + on the flat lands, but with the 11,000 lb trailer, I'm down to 25 mph on 6% grades in the rockies. The answer is a 10 speed manual, and with Randys help I have the parts assembled to do the change over, but I dunno if I care that much anymore. Just take my time.
375 hp is the realistic limit with a 3208, however it would be very difficult and expensive to build a radiator that would cool the engine, at that power setting, in a FC. My Ford medium duty toter home is turned up to that power level, that chassis allows for the cooling capacity required. Even with the 13 sp OD manual, I get passed by SOB motorhomes on the grades. That being said, the toter home will top over 90 mph. There is a Newman-Haas race team semi that knows about that top end, I-90 in Montana, 20 miles side by side, wide open. It was very cool.

Closer to an 81 than an 88, does have an 88 steering wheel though.
Front end was probably changed and headlights updated, Could be a CAT 210HP na

I would say if the title says 81 that is what it is. Maybe it was crashed and the later stuff installed. We should start a registry of our Birds along with year and serial numbers as a reference source for when changes occured.

Sure looks like an 81 or so to me. The outside has the generator curbside and this was not so in 88 it was moved to the rear on the driver's side. This inside is 81 or so. This coach is definitely not an 88. The headlights were likely modified.

See the following site for Wanderlodge history and model years.

Good luck - Bill

The 3208's are good engines, just not setup to run very fast. They'll pull whatever you want, but you are speed limited. I would go look, if nothing else just for the learnig experience.
