I only had a 5800 rpm pill for the window switch so you can see it shuts off there. My question for you guys is how high do you think i can safely spin this combo?

 

Without the graph going beyond the pill you have, I couldn't say. It looks like if the trend continues, it would make peak power at 6300 rpms.
