Fuel System Readings On Boost -Video

I've been wanting to take a video of my gages when the engine is on boost as things happen too fast to watch them. With the help of my daughter we got the job done today. Wish the tach could be included but you have to be in the driver's seat to fit it in.

Here is what your WUR does to control pressure on boost and the corresponding AFRs:

Here is what the boost gage and speedo were doing. You can see/hear the tires let loose when I punched it at 3000RPM in 1st. These are 345mm wide mind you. Hit the rev limit and jammed 2nd. It takes very little time to hit the top of the speedo which is 90mph.
