Is it possible to have a safe NOS Boost?

Hello,
I was just wondering if there is a safe amount of NOS that can be used with I/H/E Setup. Now I mean safe as in it’s no worse than running the car on normal gas, and can be used more than just twice in a year. I want somthing I can use if I was going to race, or showoff, I wouldn’t use it everyday. However I have 74,000 mi on my engine and I am warry of using anything that is not safe.
Thanks :slight_smile:

Oh and I did do a search…

I searched for NOS Safety and found nothing… Please help me :slight_smile:
