Why is Pro Stock Dodge down on horsepower ?

I've heard of all kinds of rumours. Guys used to pressurize things with nitrous, just to see if they could get it past tech.

Some of those things are:

Roll cages (yes, actually)
Fire extinguishers
Blocks
Fake batteries
C02 shifter bottles
Hidden in frame rails
Hidden containers, like in the oil pan or in the gas tank

I've even heard of guys having specially molded hoods that would hold nitrous.

One guy (can't remember who) even just stuffed a nitrous bottle in his race suit and made it through tech. Just to prove he could. Apparently his boss wasn't too pleased.

Of course there is also the Rusty Glidden confesion.

"Rusty Glidden. With his confession came a detailed description of how the nitrous system was secreted in his car. "The holding tank was the big weight bar in the back. The nitrous line started there,went over the axle housing right up to the front of the car & stopped at the motor plate, which was rifle-drilled. One of the supports holding the hood scoop on was rifle-drilled & went up thru the top of the hood scoop to a small stainless steel line that had 2 jets centered over the carbs. With .029 jets we made 120 ftlbs more torque at 7000 rpm & averaged 90 more horsepower. According to Bob Glidden , the nitrous system was detection proof. "you had to have a combination of things to activate it so a tech guy couldn't walk up , turn on the ignition & open the throttle. The shock switch had to be on, the computer switch on, the engine running & the throttle wide open. Trust me" Glidden concluded " Thats not fiction"

Now. How true any of that is is certainly up for debate. But I will say this how many hood scoop fires do you see without nitrous? How many did the dodge boys have back in the day? Broken distributor gear my ***.
