Congratulations on your swap, well done
Couple of things I see in your video that I will comment on though. The position of your filter means that the motor will be taking in air that has been through the radiator....read HOT. It has been proven that for each 10 degree drop in intake air temperature, power goes up 1 percent. Therefore, if you are taking in 200 degree air now and move the filter to the outside of the car to take in ambient air at say....100 degrees, you will have a 100 degree drop in temp and therefore should theoretically pick up 10 percent power due to the denser air (more oxygen in the available air). Of course this assumes a little more fuel to keep the air/fuel ratio where it needs to be. I don't know a lot about EFI systems, but I would think the computer would adjust for more fuel when it sees denser (cooler) air.
Other thing is, I would fashion a shroud for the fan.
