Dyno Run after 2.6 Pulley and WMS Tune

In my previous dyno post JJ at Woodbine Motorsports ran some baseline numbers on my car.

First run with the stock Ford tune
460RWHP/415RWTRQ
77.61F
24% Humidity

Second run with the Evo "Lund" Tune
473RWHP/449RWTQ
80.21F
26% Humidity
*far from the 510RWHP/480RWHP Evo advertises on their 2010 GT500 -

JJ installed a stock lock VMP 2.65 pulley, Metco Idler, Afco Dual Fan Heat Exchanger, and VMP stock look coolant tank. Unfortunately the VMP pulley wasn't balanced right and would wobble. I had to get a Metco 2.6 overnighted from Lethal Performance. (Big Props to them for the quick turn around) JJ street tuned the car today. I took it over to Adrenaline Automotive to get some dyno numbers since JJ doesn't have one yet. It was a 30 minute drive to the shop and the car sat for 20 minutes before the first pulls and only 10 minutes for the third pull. (Which was the best) Below is a video of the best run.

513RWP/500RWTRQ
70.65F
6% Humidity

That torque curve is flatter a mechanics ruler.

Yeah, that's awesome. KB can talk all the crap they want about their peak numbers and how much more efficient their twin-screw is compared to the roots, but nothing makes "under the curve" torque like a roots-style blower.

93 Octane, I'll have to call Adrenaline tomorrow and ask them. I thought I took the graph for that one but I didn't. Uncorrected was
508.57
495.53

You didn't increase your rev limiter did you? I am not a fan of this unless you have funds to build a motor.

I'll have to ask JJ where he left it at. Isn't stock 6250? I know it shows the redline at 6k.

You know the dyno graph shows he let go at 6250, most guys who up it rev it out to 6500. You should be good.

I've never believed there isn't a margin of error. Its not like you go boom of you exceed by a few hundred.

Case in point, Ford did nothing to the 08/09 Bullitt internals yet they bumped it to 6500.

No, you don't automatically go boom of course. RPM is the killer of this motor though on stock rods. I'd rather just add more boost and keep it at 6250.
