2010 Shelby Mustang GT500 | Dyno Tested | Edmunds.com

Enter the 2010 Shelby GT500. With each pull on MD Automotive's Dynojet chassis Dyno in Westminster, CA, we witnessed the power from the supercharged 5.4-liter V8 creep up further and further. Five, six runs in and the power was still climbing. EDMUNDS VIDEO http://www.Edmunds.com is a car-shopping web site driven to make car buying easy.

2010 Hennessey HPE550 Camaro | Dyno Tested | Edmunds.com
What's that? You're a power addict and the 426 horsepower with which Chevrolet endowed the 2010 Camaro SS is weaksauce? Here's your fix. The orange 2010 Camaro SS you see above has been given the full Texas-style treatment, and I'm not talking about barbeque. Hennessey Performance Engineering, headquartered in Sealy, Texas, coerces more power out of more than just Mopars and Mitsubishis these days, and he's turned his attention to Chevy's latest pony car. It's called the Hennessey HPE550. The centerpiece of the conversion is the breathing enhancement delivered by a Magnuson Roots-style blower and liquid-to-air Intercooler. Supplementing the 6 psi generated by the Supercharger is a cold-air intake and free-flow Exhaust. Owner John Hennessey tells us that the package swells peak power to 562 hp as measured at the flywheel. Aftermarket horsepower claims are notoriously optimistic, so we did the obvious thing and strapped it to MD Automotive's Dynojet in Westminster, California. The result was anything but weaksauce. First, a caveat. Before we did any Dyno runs, we noticed that the insides of our HPE550 test car's tailpipes were curiously free of the typical fine sooty layer that coats every car that runs on pump gas. Instead, they were fairly clean save for a light gray coating. EDMUNDS VIDEO http://www.Edmunds.com is a car-shopping web site driven to make car buying easy.

Camaro SS vs Challenger SRT8 vs Shelby GT500 | Edmunds.com
2010 Camaro SS vs. 2009 Challenger SRT8 vs. 2010 Shelby GT500 In our recent pony car comparison test, the retro-heavy - and just plain heavy - 2010 Chevrolet Camaro SS walked away with top honors in its debut. The big V8-powered coupe needed a new challenge. It was time to refocus the lens. Shoot from a different angle, so to speak. So we squared the brooding visage of our SS-badged protagonist up against the cruelest bunch of savages we could find, the range-topping 2009 Dodge Challenger SRT8 and 2010 Ford Shelby GT500.

First Test: 2010 Ford Shelby GT500
We head to northern California to take a look at Ford's top dog Mustang, the Camaro SS slaying 2010 Shelby GT500.





Lethal Performance 2010 Shelby GT500 10.09@140mph
We had a fun time at the track last night. Although we didn't do as well as we were hoping to we got a lot accomplished with the car and in reality did quite well. Just so there's no misunderstanding the car was making 21psi and was run on C16. No methanol was used. We dialed in the suspension a little better and was able to cut a 1.47 60ft on one of the runs. We also noticed that our stock diff is shot as we were only spinning one tire as we left the burnout box. So we'll be taking care of that this week. We also datalogged the car and Jon went over the logs with me this morning. The car was pulling 4 deg's of timing. So on our 10.09 run as we went through the traps we were only seeing 17deg of timing. He's not exactly sure why but we'll be looking into it this week. We didn't log IAT2's last night as Chris's computer was having issues logging a few parameters on our car. IAT2 being one of them. The other thing that was working against us was the weather. It was humid, muggy and we're still in the 70's. We kept scratching our heads trying to figure why we were going 2-3mph slower in the 1/8th than our last time at the track when we went 112+mph through the 1/8th. Between the crappy air the car pulling timing at least we know what was going on with the car. With that said we're going to keep on making adjustments, tweak the suspension and get the issues straightened out with why the car is pulling timing. As Derek mentioned above I believe we're going to put in a spool. To this date the car has seen 3 full passes. For us to being doing what we are especially with the weather and with the car pulling timing we're doing great. It's easy for someone to say that we should easily being running a certain time because of the power we're making but there's a lot more to it than that. It's easy to strap a car to a Dyno and make a number but taking that power and making it work for you at the track is completely different. Ask guys like Andy, Tony, Chris or any other person who runs fast times how many runs it took them to dial the car in. We can't expect to build a car, take it to the track for the first time and run the car to it's fullest potential. That's not how it works. We know that with how the car sits if we get the small issues ironed out and see some cool air we should see 9.60-9.70's. For now it's back to work and we'll be out at the track again soon. Jared
