Exactly!!! Thats what kept happening to Doug Lewis' SHO years ago. Check out SHOtimes for info. Since we (SHO/2.5l DURATEC) have similiar intakes, the same basics apply

About that time I started experimenting with nitrous oxide. I picked up a kit from a friend and started piecing things together. The learning curve was pretty steep as I was again going thru clutches and having a hard time with spark plugs. I went to the first All Ford Car and Truck show at Moroso Motorsports park in West Palm beach FL. I was having problems getting the car to make a full pass without laying down at the end of the track. It would pull like crazy, but after I shifted into 4th, the car would nose over and stop pulling. I though it might be the nitrous in the bottle, so I filled up the bottle and tried it again. This time, the car stopped pulling just as I shifted into 4th but I didn't notice it. By the time I got to the end of the track, the car was only running on 5 cylinders. My racing was over for that weekend. As it turned out, the system had leaned out and burned an exhaust valve. I didn't really know why...till later. I rebuilt the motor and added a couple of things. I installed ported heads and stage 1 Logicams. The motor ran great and had lots of power. My drag racing skills were improving along with my ET's and trap speeds. The car was running mid 14's at about 98 mph. I again did the nitrous thing and again had problems making a full pass. I was racing a Mustang and couldn't lift for obvious reasons. I ended up beating the Mustang, but killed the engine again....same cylinder, same valve. This told me that the system was at fault, so I changed the system. The problem was the intake manifold was never designed to handle anything wet. As the mix of gas and nitrous was moving thru the manifold, the gasoline was falling out of suspension and puddling in the manifold. The nitrous could make it into number six, but the gasoline wasn't. This was leaning out the cylinder and burning the valves. I knew that the system was the problem, so I changed the system. I installed a Pro Fogger style system with six individual nozzles that shoots both nitrous and gasoline directly into each intake runner. This eliminates the problem of puddling in the manifold. The results were dramatic. The car would make a full pass and was making tons of power and mph. Now, with all the suspension mods and good track tires, I'm running mid 13's at 106mph.

I am the NECO'er who ran the digital progressively controlled 150 shot on a MTX. I don't think Puck mentioned that this large shot was just a one time affair. I seriously doubt the clutch or axles could handle it for many runs. Even with the shot progressing there was lots of wheel spin and hop. Normally I only spray 75-100 shots with the NX kit.
