Nitro vs Brushless

[Shark413]

I have just finished my brushless 1/8 buggy (described in another post). I now have two 1/8 scale buggies of the same make, one nitro and one brushless. And now I am wondering which is fastest around the track? Well if the weather holds up I will take both buggies out to the local track and make some timed runs. If everything works out I will post the results. Which one will be faster? You choose..
