A few years ago, on the previous incarnation of this board, someone started a thread to see who could post the best written account of the nitromethane experience. This was my entry. It was my account of my introducing a good friend to the startup experience. I thought of it when I read about Al's passing, as my friend got his first taste from none other than Al Hoffman and his famous BDS Thunderbird. He's been a serious nitro methane junky ever since, and I offer it up here again as a tribute to Al Hoffman, one of my all time favorite Fuel Coup racers.
RIP Al. We'll miss ya man.
First Taste Of Nitromethane.
Years ago, I took a close friend, Paul, to Brainerd International Raceway for the Northstar Nationals. While he knows a lot about cars and owned his own hot rod Cutlass, amazingly, he'd never been to a nitro race before. I decided that needed to change, and told him nothing about what he might expect.
The first car he experienced was Al Hoffman's BDS Thunderbird. (This is when they were still driving the dually with the BDS blower sticking through the hood. '88, I believe.) We came upon them as Al was mixing up a load of nitro. He took a can of green stuff, poured some in, swished it around, then poured some clear stuff in, swished that around some then moved to the car to pour the nitro in. He stopped before he began, thought for a minute, set the jug down and grabbed a can of red stuff from the trailer (Fifth wheel type.) and poured some of that in, thought for another moment, shrugged his shoulders, and poured the remainder of the can in. He dumped all of this into the fuel tank, capped off and made ready to start the car. Al climbed into the seat while his crew guy walked around and checked everything on the engine and made sure everything was buttoned up. He put the starter onto the blower pulley and grabbed the squeeze bottle of alcohol. With a nod from Al, the crewman squeezed the trigger and spun the motor over for about 10 maybe 12 seconds and quit. (I assume to bring the oil pressure up.) He disconnected a jumper on the magneto. Al had hold of the brake lever like a Cowboy has hold of the reins of a bull at the rodeo just before he gives a nod for the gate to open. He nodded one more time. The crewman squeezed the trigger again while holding the bottle to the injector opening. This time the engine coughed to life, and immediately settled into that throaty high RPM sound blown alcohol motors make. Everyone looked around for leaks. Upon a thumbs up from everyone, the crew guy reached down and pulled a lever on the fuel pump. All hell broke loose. The engine took on it's Mr. Hyde personae as the sound level immediately jumped down two octaves and up a couple dozen decibels. The car was rocking side to side on the jack stands snapping, spitting and popping. The exhaust headers started spewing clouds of noxious yellow fumes, and the weaker amongst the fans started scattering. Fine with me, I just shoved Paul up closer to the car. Al got one more grip on the brake lever, gave another nod, and finally gave the throttle a whack. The engine immediately responded with a really loud and sudden WHUFFFF!!!! and the car jerked on the jack stands like the rodeo bull had just had a hit of the electric cattle prod. It sent pit ropes flying, and even more noxious fumes erupted from the pipes. When they whack the throttle like that, the sound level makes an instantaneous jump a couple thousand decibels, and your ears pretty much say "Sc**w it!!" and quit working. You just don't HEAR the sound. You FEEL it. It's like you take your balled up fist and hit yourself on the chest bone. More weaklings scattered, and I held a firm grip on Paul so he couldn't get away. I told Paul later I was certain that, with his fingers firmly in his ears, he cleared 12 inches easy on that first hit. Al cycled the reverser, whacking it a couple of more times. More yellow fumes. More cackling. More noise. You swore the car was trying to leap off of the jack stands. Then the crew guy stuck the alcohol bottle back in the injector hat, and shut the fuel pump off, and the engine regained it's Dr. Jekyll personality, going back to that alcohol sound, which seemed tame now, before finally chortling to a stop. There's always a few moments of stunned silence afterwards, before the fans start chattering and laughing with each other, along with some cheers and whistles. The die hards amongst us scattered off looking for the next car getting ready to fire up. My friend Paul turned around, tears streaming out of his eyes from the fumes, and asked "Good Lord, why didn't you TELL me it was going to be like that?!?!?!?" I just told him "Paul, there's simply no way I could have prepared you for it. You just have to do it." He turned into a junky after that. Couldn't get enough.
