 A real race engine, isn't expected to last more than one season.
 Even if it would, it gets "freshened" during the off season.
 Those in an 8 second class, might make 4 or 5 runs in a day.
 Possibly two days on the weekend.
 A season seldom consists of more than 25 weekends or so.
 Let's say 5*25=125  1/4 mile runs. In a run, the engine will
 make about 900 revolutions total, including the burn-out.
 Let's then double that for pit time, idling over to the start line,
 and back from the finish line, and such.
 That's how many total revs in roughly a total life expectancy
 of around 60 miles ?

 A transmitter is expected to last some 20 years or so, with air
 flow constant 24/7.

 In both cases, more air is better.
 In one, most of the dirt and dust is incinerated within, and in the
 grand scheme is of no real consequence.
 In the other, it sticks to parts, and inhibits cooling.

 Made for racing does not mean better !! Never did.

 Still, the idea of clamping an automotive intake filter on the inlet
 of a transmitter squirrel cage blower is innovative, and certainly will
 not hurt anything. Since it's after the main cabinet inlet filters, the
 efficiency of that automotive filter isn't a big deal, if the cabinet
 filters are anything more than a chicken wire screen.
