Just a little tip. If you guys want to make a starter sound, the speed should be the same as the engine speed.
Modern cars toko like less than a second to start, so starters should produce different sounds from 0-500 rpms (?)
Most modern cars will start within a single rev. Seriously. What usually happens is the starter motor turns the engine over enough to gain compression in a single cylinder, that cylinder tends to ignite rather easily, bang, the motion of the single cylinder firing is enough to crank the rest of the engine. Certainly none of this cranking to 500rpm and leaving it there before starting, its like you've never been in a car or something. Midst of winter my old 1999 Skoda Felicia with 150000 miles was sophisticated enough to fire on first crank. Corsa was *always* second crank. My focus is starting to get issues cranking due to a flat battery, but turn the blower off before starting and it will go in 1 or 2.
my '97 tahoe with 150k starts on 1-4 cranks depends on how long its been sitting (the thing can sit for months at a time)
