Good evening fellow race fans. I,m not sure if this is the right forum, or area, to be posting this, so bare with me. For many years I thought I was pretty up to speed on nitro drag racing. How wrong I was. Since finding nitromater, and reading all that my fellow maters know that I don,t, I was aghast. I love nitro racing as much as the next person. But my knowledge of the sport, is sorely lacking. So I,m hoping I could get you folks to answer a few questions for me. Please no giggleing as you read this. Here go,s. What is the spray I see coming from the top of what I assume is a nitrous car. I assume it is actual nitrous. Is it excess. During warm-ups in the pits, on the fuel cars, I always thought they we,re looking for leaks, parts falling off, and such. Is that the case. I am also wondering what the difference between a blown car, and an injected car. I,m thinking injected means ,ambient air is forced into the engine by mechanical means. And blown cars are simply supplied air thru the scoop. I,m pretty sure I,m wrong on this one. This really hurts my ego , to have to ask these things. Wait ,I have more. Can someone run me thru the starting line ritual,I understand staging, and removing the throttle stop, turning on puters. I know, I,m long winded.Any help here, would be welcomed. Is there a tried & true way, to catch the teams firing the motor,s in the pit,s. Thank you all for your time, and expertise.
