What's up, this past Saturday I drove up to Canoga Park - which is way the fuck out there even if you live in L.A. - for their open house and their $50 dyno day.
There were two dynos, one was the one that Precision Z had while the other was the one Tony owner of Motordyne had. He had his dyno tuned specifically to the liking of
Church's . Tony's is higher than Precision Z's

but I didn't care, I just wanted to get dyno.
My results:
My mods:
Fujitsubo Legalis exhaust + Fujitsubo Y-pipe, Z-tube + JWT pop charger, MREV + 5/16" spacer, DC Sports Headers, UR pulleys, and Berk Technology Hi-Flow Cats.
252 rwhp and 248 ft/lbs of torque. respectable numbers. add 30 if you want to know what I would of gotten on Tony's dyno.
Precision Z used an 08 350z with the HR engine + greddy exhaust and it pulled 250 rwhp on the Precision Z dyno. In the same gear, it pulled 280rwhp on Tony's dyno. This became the standard to compare it to.
