As some of you know, I'm currently the happy owner of an 84FC35SB. I like the
size of our coach and the fuel economy of the 3208 but have to admit it's a bit slow. I recently started taking a closer look at a low mileage 1991 SP36 and would appreciate any info folks can share on performance and reliability of the rear mounted 3208 and 5 speed ZF transmission. These coaches had a fairly short production run and I'm curious why. Did they have any warts I should know about? Appreciate your thoughts, Eric in San Antonio |

the 91 has a intercooler. I think the 88 FC 300hp is intercooled. the
3208TI gets 20% more power. a 3208 Na naturally asperated just sucks in air for the fulemix when the piston draws down. The 3208t Turbo has a fan that is powered by exhaust air. In the exhaust is a fan blade that spins as exhaust passes. On the axis of that fan is another fan that pushes fresh air into the piston. The more air you can pack in, the bigger the explosion. The problem with a turbo is when you pack air in and compress it, you heat up the air and it thins out. the added intercooler cools the compacted/compressed air making it denser and allowing more air to be packed in a small piston space. that gives a 300 hp explosion. you have to design the valves and injectors around the amount of burn so aftermarket is not as easy as just adding a turbo or intercooler.

Eric,
I have owned a 1990 36sp since January of this year. Thus far it has exceeded my expectations. This is my first and only motorhome, so I don't have a lot to compare to, but thus far I see no warts. The only negative I have is access to the engine, it has a swing our radiator in the rear and you get to the top from under the bed. I had to change and exhaust manifold gasket, and it was no easy task. I don't know if it any better or worse than any other disel pusher in that regard. As far as the Cat 3208 turbo, it is still no speed demon, but the power is adequate for my needs. Regards, Dave |

Eric,
We made the transission from a FC-33 to a SP-36 two years ago and for the most part, are very satisfied. One of the engineers at BB told me it was one of the best coaches they ever built. They ride and handle well, plenty of power, and are very quiet. There's an abundance of storage outside and inside. The things I don't like about them are the difficulty of accessing the engine, and availibility of service for the ZF transmission. We had a ZF control module go bad. They no longer repair/exchange the module so a new one is about $7,000. I ended up taking mine to a very good TV repair shop and had it fixed for $85. This won't always be doable though. ZF should continue to service their products when used in $300k motorcoaches that last thirty plus years.
