With Superchargers, there is a lot of blow through through the heads and makes it difficult to build pressure. Reducing the overlap and running a less aggressive profile will allow

With Superchargers, there is a lot of blow through through the heads and makes it difficult to build pressure. Reducing the overlap and running a less aggressive profile will allow the SC's to get boost up quicker. Don't quote me, but I don't think turbo's have this same problem. It's also a big reason why long tubes weren't making the same power as a stock header because the heads and exhaust were too efficient. It made more power per lbs of boost, but not enough boost to make more power than the stock headers. I feel being able to control VVEL will be a big deal for supercharged cars. Maybe we can reduce overlap to increase pressure, and open it up progressively so it gets top end efficiency. Just a theory, but it sounds good lol.
