Damp Track, Drag Radials, & a Pair of 750 HP Roush Mustangs = Savagery

By -

Roush Mustang

If you gotta go up against a Roush Mustang on a drag strip, you best bring one of your own. And a set of cheater tires doesn’t hurt.

A bone stock Mustang GT cranks out 460 horsepower. Not too many years ago, that was supercar territory. However, nowadays if you want to make an impression you need to up the power ante a bit. Thankfully the folks at Roush Performance got you covered. They have several packages that will give you more power, and the jump on a stock Mustang. However, what if the Mustang you are racing is also a Roush Mustang? A Mustang verses Mustang race is quite common. However, what if both cars are making the same power? In those cases, the race often comes down to the driver. And other vehicle components such as tires.

What we have here is a drag race taking place in Australia between a pair of Roush-supercharged Mustangs. Each of them makes 750 horsepower, but there are other differences. One is a stock Mustang GT with the supercharger kit. The other car gets the full Roush Stage 3 treatment. In addition, the Stage 3 car has a set of Mickey Thompson drag radials. Will the tires and other Stage 3 bits make a difference? Did we mention the track was damp? Checkout the video posted on the Motor YouTube channel for all the details.

The Combatants

Both the Mustangs here were tuned by Mustang Motorsport in Australia, and both have automatic transmissions. One of the Mustangs has the supercharger kit that cranks out 750 horsepower. That is basically it for modifications on that car. The other Mustang has the full Stage 3 setup, so it makes the same power but has some other goodies. The Stage 3 car gets some suspension upgrades, some aero tweaks and additional cooling. It also has another party trick which is a set of drag radials. However the cars will race on similar rubber for the first couple races. Will the extra bits on the Stage 3 make a difference in a drag race?

Supercharged

First Couple of Races

First race from a dig and the Stage 3 car jumps out to an early car length lead. That lead remains fairly constant the entire length of the track. Both cars a moving fast but the supercharger-only car doesn’t have any advantage to be able to claw back any ground after the slower launch.

Race two is a bit different. The supercharger-only car jumps into the lead by about a car length. It actually looks like the car may have jumped the start to get that kind of lead. However, the fact is the car is ahead by a good margin at the start. But in this case the Stage 3 car is able to claw back the distance lost at the start. By the end of the run the Stage 3 car takes the win by about a quarter car length. Not sure if the extra bits made the difference or if this was all driver, but it was an impressive comeback.

Time To Cheat

The Stage 3 car has already won the first two races, but now in race number three it is given another advantage. The street tires are swapped out for a set of Mickey Thompson drag radials on the Stage 3 car only. This is not looking like a fair fight. The Stage 3 spins the rear wheels at the start despite the drag tires. However, it still manages to get out to the early lead and win by a little over a car length.

From a roll the Stage 3 car races to its easiest win yet. Both cars mash the throttle, and the Stage 3 car just rockets ahead and wins by a huge margin. The supercharged-only car lost every single time. It could be the driver, it could be the tires, it could be the extra performance options on the full kit. But whatever the reason on this day the Stage 3 car was undefeated.

The Video Replay

Check out the video below for all the Roush Mustang verses Roush Mustang drag racing action. The cars are generally close, but the Stage 3 car seems to have just a bit extra that makes it impossible to beat.
