The 84mm is at 91280 at 7k rpm......a 80 mm would put you over 100k ...
Also TOPGUN is correct ..if you blow the supercharger you could damage much more than just the bottom end .. we all take that risk when boosting but ....I wouldn’t go that far over specs on a blower

I might be reading the charts wrong soooo ......im still not sure

It's my chart and you are reading it correct.
