massive reconfiguration time again.

the spring adjust how fast the door comes open. But, there may be a way you can adjust how FAR it comes open as well. That's critical as well. When I was running TQ's years back, they had a tab that you could bend (it was slotted to bend) that controlled how far the door opened, and the spring controlled how quickly it opened.

Honestly it seems like there's a lot of room for air to get around that door even when it's closed.. I'm pretty sure there's only the tension not a how far can go adjustment... remember I don't think this motor is going to suck the whole 1250 CFM LOL..
