VRIS. Knew that title would grab your attention
I know The best modification at this point still seems to be boring out the intake runners, but was wondering if there was a computer solution.
Also, Anyway to stop the butterflies from closing at 6500!!!

Thanks,

If I knew anything about electronics I'd do this myself, but you can make a small switch that can monitor the RPM and then ground the VRIS solenoids at 6500 to open them.

Also, there was supposed to be a couple of guys who were going to work together to produce VRIS controllers with dials to control the opening and closing of the VRIS plates. Unfortunately as they got close to production I believe one of them was called away for military service.
