Hello, guys!
I'm from Russia. I do have a problem. The piston burns all the time at the NOS power more than 150 HP. The engine specification: volume - 1730 cc (106 c.i.d.), cylinder diameter - 84 mm, stroke of piston - 78 mm, 4 cylinder, compression 11.5:1, gasoline octane +116, ignition less then 20 degrees, 4 throttle bodies (EFI), 16 valve, engine power - 225 HP, technical NOS, system direct port 4 cylinders is used.
Tell me, please, what is standard chemical composition of your technical gas NOS?
