...so i should be fine with just the 1 alloy?....and then when i go to 30% what shims should i add?
Cool - but please do read the article. It tells you pretty much all you will need to know on shimming the GO motors, as well as plug choice to match which is important.
If your going to 30% I recommend a medium plug like O'Donnell 97T
I currently run 30% with .4mm shim stack and OD 97T and couldn't be happier with the performance and reliability
