The little M90 supercharger that came on a 3800 V6 has a cult following and Richard Holdener has done tons of testing with them. He’s ported them, carbureted them, and so much more. He’s tested them on everything from the 3800 V6s that they came on to LS engines, and with lots of configuration changes. If you want to see all of them, then this is the video for you. Check it out.
