on that note Helix... that you only care about how fast your car is...
I've ALWAYS noticed that high horsepower cars will throw flames..
any dyno video, or track video will prove that high horsepower cars will throw flames, one example is the Ferrari F40 or the Pagani Zonda they spit flames upon deceleration all the time..
dyno video's you will watch a car go balls out and let off at red line and watch the fire belch out of it's rear..
I personally have always considered flames shooting out of cars as well tuned car! Looking at the car right away you can conclude something ins't stock anymore under that hood.
Then again, I am obsessed with WRC cars and Group B cars throwing flames, and nitro burning drag cars, and Forumla One cars... sooo that might be an influence to my opinion.
Ohh and my car shoots flames, but it is FAR FAR FAR FAR from high horsepower.. just a very hot exhaust a turbo and lots of unburned fuel.. but that defeats the point..
when an average person walking down the street observes a car shooting flames what pops in their head? "Ohh sweet a race car"
My opinion
