Ugh…people have only been doing this for years. Many spray the nitrous before the turbo let alone spraying it in the hot side pipe and then have the fuel injected later. Check out some high HP turbo/nitrous import drag cars.
Yup it works fine if done properly. We’ve sprayed meth through blowers and turbos with great results. On the blowers I just recommend making sure they’re coated with something the withstands water/meth mix. I haven’t seen any wear/corrosion on turbos, but the supercharger manufacturers make a big fuss about spraying water/meth through them if they aren’t teflon coated so I’d ask to play it safe.
