Good news is … the car held up good on the dyno last night.
Here is the graph of the pull when it was on the #14 pulley. It put out a max of #12 on the #14 pulley. Now keep in mind mine is the top curve. The bottom curve is from a 2002 mustang gt with stock everything with the same 1.7L KB on the #9 pulley(his made 436rwhp with this setup). However his was run when the temps were in the high 60′s and not 90′s like mine yesterday. Also i believe both were with 18 degrees of timing. My CR is 8.7:1 so im assuming that’s the difference as well as the heads, cams, and exhaust my engine is more efficient so it produces less boost.
In the graph below the 440rwhp was with the #14 pulley producing #12 of boost and 22 degrees of timing. The tuner thought the 22 degrees was a bit much so he backed it down to 20 degrees. Thats the 336rwhp max in the graph.
