Thanks for the comments, a work in progress obviously!

Whine is from straight cut gears as Costa mentioned. The GT40 is a bit large for the car and I haven't really turned the boost up yet. I may not until I get ITBs, I want to be damn certain each head is getting equal air fuel.

To compare, it spools almost identically as my baby k29, a bit sooner but not much. It has the potential to flow much more, I'm running less boost and there is definitely more power. My pancake manifold is my biggest restriction, it will be next to go.
