Are there any dyno charts of an sp66 yet? I've seen charts of the sp63 and track times, and they are just incredible. I have a T61 .70 right now which is great, but I'm in the middle of building up my motor and thought maybe I should get a bigger turbo as well? I just can't decide which to get. It's gotta be pretty streetable. I was thinking either an sp63 .81 or else an sp66 .?? Please let me know what you recommend. If anyone wants to trade/buy my T61 please let me know, in case I decide to change turbos. I've only had it 1/2 year and I've only run high boost a few times, since I live in MI and the weather has sucked until recently.
