Yes, yes… I know everyone hates the dyno, but here is a copy of my post from the other site. It’s interesting to look at none the less. I think, but whatever. Here it is…
I got together with two other local members today for some dyno runs (andthen and GRUMPY-S4 on here). We each made 3-4 passes on a Mustang dyno in various states of tune. Let me get this out of the way… Dynos are a tool to use for tuning and logging. That’s it. Please don’t try to compare these results to results from any other dyno, or read too much into it. Just take them for what they are. Our 1/4 mile strip is closed, and more than anything we wanted to do some logging to see how everything is working right now. The dyno is a great place for that.
Here are some details on the dyno.
Location: PRT Performance in Lewisville, TX
Type: Mustang AWD Dyno
Conditions: 45 degrees F, 100% humidity. Corrections for conditions were used. Corrected numbers were considerably lower than actual due to the cool temps.
This Mustang dyno reads low by most people’s standards. It’s known as a heartbreaker locally. I’ve now dynoed on it several times including several different stock B8/B8.5 S4’s, and it has always been amazingly consistent. Every single stock vehicle has dynoed in the 265-270 awhp range. For another point of reference, a new Dodge Charger SRT (392 Scat Pack) came by as we were finishing up, and dynoed at 347 whp/378 wtq (they are rated at 485hp/475tq). He was pretty heartbroken… By all accounts, this dyno reads about 10% lower than the common DynoJets in the area.
Here is a link to the results from several other B8/B8.5 S4’s that have dynoed on this same dyno: http://www.audizine.com/forum/showthread.php/619767-Stage-2-Dyno-Results-2014-GIAC-V1-and-V2-2014-Revo-2012-APR
OK, with the formalities out of the way, here are the results. I also logged all three cars. I’m not going to post the logs here because it brings up a lot of wannabe tuner conversations, but if you’re truly interested in the logs, shoot me a PM, and I’ll see if the owners are willing to share.
Grumpy’s 2015 DSG. 93 octane. Thanks to EPL’s flash at home setup, we were able to easily test the stock and stage 1 tunes.
Stock tune, APR DSG tune, APR intake (1/21/2016): 268 awhp / 283 awtq
EPL stage 1 tune, APR DSG tune, APR intake (1/21/2016): 337 awhp / 341 awtq

Comments: The stage 1 tune gained 69 awhp and 58 ft/lbs. If you’re still driving an untuned car, you’re missing out!!! We also only drove the car on the dyno for about 10 minutes to let the stage 1 tune adapt. It would have probably gained a little more power if it had more time to adapt, and if the car was a little cooler (temps were cold today, so heatsoak wasn’t a huge issue as we kept an eye on coolant temps and IAT’s).
jran76’s 2012 DSG. 93 octane. The dyno graph is comparing today’s runs with previous runs for October 2014.
APR stage 2 V2, AWE exhaust, CTS intake (10/11/2014): 349 awhp / 335 awtq
APR stage 2 V3, APR DSG tune, AWE exhaust, Alpha coolant system, ECS intake (1/21/2016): 383 awhp / 351 awtq

Comments: The new (V3.x) APR tune and DSG picked up 34 awhp and 16 ft/lbs. The coolant system was new, but it didn’t play much of a role today due to the low temps. Obviously, I’m very happy with the changes.
andthen’s 2012 DSG. Mostly E85 (maybe a little 93 octane mixed in).
EPL stage 2 for E85, APR DSG tune, Autotech HPFP upgrade, JHM overdrive crank pulley, Roc-Euro intake (1/21/2016): 414 awhp / 413 awtq

Comments: Holy torque monster. Here you rally see the gains from the second pulley with massive torque gains up top. andthen has done some 1/8 mile passes that work out to mid-11 times, and this gives you a pretty idea why.
Just to compare, here is andthen’s graph (red) overlaid on top of my graph (black). The big difference being the dual pulley setup (worth an extra 2-3 psi of boost), and E85 (worth an extra 4-5 degrees of timing).
