Can PSI in tires affect roadspeed?

Yeah, fixing a leak on the intercooler hose is even easier than fixing a coolant hose (radiator hose) leak - simply because you've got no coolant to deal with ... and it's the same basic procedure to do.
Other things that can cause slow issues are fuel filters, or full water separators. Hope some of those suggestions help. as for not blowing out the filters - those sweepers should have good snorkels on them that help keep the dust in the filters to a minimum, so just monitor the restriction on the filters, and replace them when necessary. Preventative Maintenance should be followed very strictly on these sweepers. --Dave.

There'll be some dust that comes out of the filter when I blow it, but by the time I get done, there's hardly any that comes out at all. http://www.classadrivers.com/phpBB2/...ght=air+filter
Air filter maintenance is also sometimes misunderstood. Filtration experts all describe their worst nightmare: a guy pulling a primary filter off an engine, knocking it on a fender to loosen up the dust – or blowing it out with an air compressor – and then re-installing it. Although not uncommon, this practice is guaranteed to send that engine to the rebuild shop much earlier than necessary. Knocking dust out of a filter or blowing it out with compressed air immediately allows dust to accumulate on the clean side of the filter. And blowing compressed air onto a filter may remove a lot of dust but it also forces some dust more tightly into the fabric of your filter media, thus increasing your restriction.

don't forget to blow out your radiators too ...
Plugged filters shouldn't cause the machine to run too much hotter - but like those guys are saying, if you start to blow out the filters, and basically force that dirt through the filter, it can get into the turbocharger and wreck that, plus when it gets into the engine itself you'll cause all sorts of severe wear. Anyhow, when you get a chance, run that thing out on the highway, with fresh oil, fresh filters (air, AND fuel) and make sure the tires are properly inflated, and that you're completely empty (no water, empty hopper) ... and give 'er hell. I discovered last night (in a 70mph zone) that the top speed of the Elgin Eagle is 74 1/2 mph. I kept her there for about 4 miles or so, and after that, she just "felt" more peppy. That's probably all in my head, but still - this conversation came to mind after that. One other thing to check, that may have been overlooked - if it's got a two-speed rear end, make sure it's not in Lo - in Lo, the eagle won't top 50mph. New Filters are ALWAYS cheaper than new engines. If you've ever used a K&N air filter for your car, you'd see in the cleaning instructions it tells you to use low-pressure water to wash the filter, that's because the high-pressure water, and/or air will push the dirt through to the wrong side of the filter. --Dave. ... this gives me an idea - I wonder if I could design an oil-bath air filter setup for these sweepers - that'd be sweet, and way more effective.

Ahhhh, you will find you are twenty years behind the times, they thru out oil bath filters about that long ago because they didn't work. Leave it alone and change it on regular maintinance or ig the little popper sais it need it
