These AMR500 are only 500cc x 1600rpm are only good for a 1.4l 6000rpm max engine or smaller. You are going to need another one for a 1.8l or 1.9l. Max rpm ratio calculation (aka ratio for Pulleys) 16000rpm supercharger max Divided by engine rpm max 6000 = 16000/6000= 2.66:1 drive ratio. Now 500cc per revolution supercharger multiplied by the drive ratio 500x2.66 = 1330cc max displacement on a 6000rpm engine and that’s 0 boost so no power. These sc can be over reved to 18000rpm so the actual mechanical limit is 18000/6000=3, 500ccx3=1500cc So if you put this on a 1400cc or 1.4l engine you can expect to see 1psi of boost. On anything bigger 1400cc your really need 2. Or just a bigger s/c.

make a test drive video 0-100 ...

World McCrea yeah my math was off I forgot to account for 4stroke displacement, is half of total displacement so yes should be fine for 2.0l
