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 
Oh and I did do a search…
I searched for NOS Safety and found nothing… Please help me
