I moved to Wexford late last year and have been to N. Park a few times with the Sup. I don’t drive it often, about 2,500 miles so far this year. Got to keep it emissions exempt! And thanks.
It is very streetable with the 71mm. I’ve never gotten a clean dyno pull on it (damn boost leaks) but b/c I have a 4l80e and a 4,000 stall, it won’t lay down anywhere near 900rwhp on a mustang dyno. My guess is that it would be closer to 650 rwhp.
I haven’t gotten anyone to ask me that yet.
