And where you can buy it ?
All the best

Its mainly a show for the crowds, but they are purging the lines of any air that may be trapped. Its expensive to just blow off like that, but when you have $100,000 engine in a $200,000 car, what the heck is a nitrous to you!

And funny cars are either nitro or alchohol! Since he thought it was steam, I doubt he knows the difference between a pro-mod (door-slammer) and a funny car. | | | | | Joined: Sep 2009 Posts: 21 New Guy | | New Guy Joined: Sep 2009 Posts: 21 | 46gmcpu I don't think you did it on purpose, but it would have been better to explain the difference instead of insulting him. | | |
