2011 GT500 2.6/90 pulleys, JLT Big Air and NGK TR6 dyno results.


Recommended Posts

Just got some mods finished to my 2011 GT500. I had Brent at Dyno Tuned Performance in Virginia Beach (dtpracing.com) do a custom tune after they put on a 2.6 pulley with 90mm auxiliary idler from Evolution Performance (evoperform.com) with NGK TR6 plugs and a 127mm JLT Big Air CAI (jlttruecoldair.com). Also had them install a BMR adjustable upper control arm and mount and lower control arms from BBR (blowbyracing.com).

The baseline was checked on the first day then sat overnight for the engine to cool to do the mods. The temps were pretty much the same both days, upper 80's. it is a Dyno Dynamics Dyno.

The outcome was fantastic and I'm extremely pleased with everything. I am particularly surprised at how much the control arms improve the back end. I can accelerate WOT without the ass stepping out on me now.
