Dyno Wars! - Part 3
We put fours 'Stangs on Dyno and see which one comes out on top
Horsepower. When it comes to car enthusiasts, it's one of the first subjects brought up in conversation. Chicks dig it, guys dream about it, and if you want it, then all it takes is money. So if you want to build status within the Mustang community (or automotive community in general), there's no better way than making big power on the chassis dyno.
About a year ago, the MM&FF staff was brainstorming during an editorial meeting when the Dyno Wars idea was born. Initially it was going to be much more specific, say for S197s only. But then it hit us. Why narrow it down so much? Keep the rules simple and open it up to anyone. That's how to make it an exciting and successful challenge.
But we didn't want 275 drag radial cars or Pro Outlaw race cars showing up and ruining the fun for the core group of our readers who have street cars. Besides, what's better than being able to drive your high-powered Stang on the street? So rule #1 was for the cars (or trucks) to be all street-legal and registered. We had to add the ZR-rated/competition tires and tailpipe rules later for the sake of safety, but we stopped there.
We started in Tampa for the first installment, moved to Pennsylvania for the second, and we're in Michigan for Part 3. Walsh Motorsports was our host facility, and is located in Wixom. This high-tech speed shop was born as an extension of the other Walsh-owned company, D&D Performance. Don Walsh Jr. is the proprietor of Walsh Motorsports, while his father and manual-transmission expert Don Sr. runs D&D Performance. Both are class acts, and we couldn't be happier to include them in our dyno challenge.
The day before the event, we had a couple of competitors drop out. After seeing the results from Part 2 in the Aug. '12 issue, their feet may have gotten cold. Or they could have had legitimate problems. Either way, we needed a couple of cars to fill the slots. Being a little late to phone our alternates, we called Donny himself. He offered up his own daily-driven, single-turbo '12 Boss, but we needed one more car.
Thankfully, Ford had given us a brand-new '13 GT500 to drive. So with our cars lined up, we proceeded with the competition. The weather was hot and muggy on the day of the event, but at least it would be fair for everyone. So without further delay, here are the results. Enjoy!
'11 Mustang GT
Josh Lupu's GT is not only a great example of exactly what we were looking for to when we dreamed up this competition, but even better, it is a rolling tribute to fallen and wounded soldiers. Companies Webasto and MRT built this former SEMA car in 2010 to showcase the latest Mustang parts available at the time, and now it serves as Josh's daily driver.
Some of the finer points include a 2.3L Roush TVS supercharger, a VMP Tuning tune, a full H&R coilover suspension, SSBC brakes, 20-inch wheels, and Katzkin upholstery. In other words, it looks like it could pass as a show queen. But after strapping it down on the Dynojet, we saw that Josh's GT was anything but timid.
It laid down an impressive 558 rwhp and 512 lb-ft of torque on the first pull, but Josh wasn't happy. He made a phone call to his tuner, Justin Starkey of VMP Tuning. Starkey said it was okay for Josh to add a degree of timing using his handheld SCT tuner. After re-flashing the computer, the Coyote screamed to redline. The result was 580 rwhp and 526 lb-ft of torque. Though the lowest of the group, we admired the GT's well-roundedness.
