So, who is down to supercharge a northstar with me? Hahaha. I think it needs done asap lol. What are some other ways one could make there cadi faster? Oh btw i spelled supercharger wrong on the post 
I would say that is a fair estimate, probably more though.I don't know nothing about this stuff but id guess it would probably be somewhere in the corner's of 10k-15k
but then again i have no clue what im talking about so it might be more or less
