How much life are you cutting off your engine if you spray is every couple weeks once or twice w/ a 100 shot? I am considering it, but my motor only has 30k on it and I dont want to screw it up w/ nitrous. Just seems like a waste of a good motor.

 

if setup right it will last many years / bottles. Put it this way I sprayed a 225 shot on a stock LT1 for 2 years and pulled it apart and it looked brand spankin new. I suggest a fuel pressure safety switch and a window switch

 

For a little over 6 years when my motor was still stock, I ran a dry 150 shot, and now Im running a wet 125 shot(to the wheels) with the mods below......Everything is still perfect, and the car dosn't even burn a drop of oil.......Like was mentioned, if you make sure to use a fuel pressure safety switch, a window switch (especially for a stick car), one step colder plugs(just to be safe)....and I would also pick up a good ignition like the MSD digital 6 or the mallory unit.......this way you can pull the proper timing to make it as safe as possible(2 degrees per 50 HP of nitrous) you should be good for many, many years without any problems

 

but very few people have that kinda like....

jsut make sure you dont lean out and keep up on the solenoids car and you will be fine.
