Correct, no TB installed. The headers are the only performance mod actualy installed on the car( well and the HE, but not sure that adds any power). Other stuff has been in the trunk for months! No time to install, but will be corecting that next thursday.

I will do a dyno after the mid-pipe upgrade, but I will be doing the pulley , TB and tune before that, so not sure how the numbers will translate to a stock car.I am going to use a custom x-pipe.

Unfortunately I did not get a dyno of just the midpipe, but my next dyno with Midpipe, 185mm pulley and tune netted 500whp and 575WTQ so I picked up another 52 whp and 100 LB/FT with the heat soak rapidly killing power. Still more in her as I need to install the 82mm TB and Meth. Hoping for 530ish WHP and better then 600 Tq.

Almost a year later....didn't the heat exchanger help with the heat soaking? Any new numbers to share with us?

Nothing really solves the heat generated by the 185 and larger pullies, only recovery time is helped. I have some new tricks up my sleeve like a NX cooling kit with a tube and shell heat exchanger I am going to run in series with the existing upgrade SC. Last dyno number were about what I called. 530whp, 599wtq.
