NOS is overrated Yes it is INSTANT HP. However it is way to hard on Pistons and Rings. Your setup is not right your looking at 5K Overhaul for an engine to accept it. Now with a Turbo it is Free Power or Supercharger you can put in a Popoff Valve and never get above say 10PSI and not have a problem. Sorry talking to someone that setup motors for NOS.
They only burn up pistons, rings and spark plugs if they are set up too lean which generates too much heat. A fatter mixture keeps combustion temps down and avoids burning stuff up. There are 5.7 Tundras running a 150 shot on the stock motor. The Toyota 5.7s are pretty tough from the factory. Forged pistons and crank. High strength connecting rods and rod bolts.
You just have to read the plugs and adjust mixture accordingly. It would be nice to be able to retard timing a bit, but I am not afforded that luxury. Toyota locks down their ECUs very well. I'm going to set it up rich and monitor it with a wide band 02 and AFR meter, then begin leaning it out until I reach the right mixture.
