I've installed one of these in my buddies 240sx w/sr20det. It makes a loud bang when you get it to hit the limiter but I've never been able to get it to spit out a flame like in the videos. The launch feature is a nice feature. I hooked it up to the clutch switch so when you have the clutch all the way down it it kicks it on until you dump the clutch. It just takes a negitive trigger so you could just hook it to a push button if you wanted to.
