I am at Techco right now at their badass open house while they finish up the tuning on my car...Here is what happened: The 3.6" pulley and Roush tensioner were installed and the car was put back on the dyno.
Previous numbers:
458rwhp @ 5.5psi (spiked at 6psi)
403rwtq
New numbers:
488rwhp @ 6.5psi (spikes at 6.9psi)
439rwtq
All numbers are SAE corrected. So a gain of 30rwhp and 36rwtq for 1psi....not bad
By the way, they revved the beast all the way to 6800 five or so times...stock motor with 488rwhp holding strong (knocks on wood). I feel comfortable with the power because the boost is so low and the torque is not too high. Can't wait to drive this beast. I am going to go back to my car and snap a few cell phone pics of the car so you guys can see her. She looks naked, but sexy
Be right back gents...
