Bringing this thread back from the dead. I bought my car forever ago of from me photoman. Been spraying meth through it for over 10!years. I’m now running a wet nitrous kit through it to and changed the meth system from a 3gph to a 6gph progressive supercharger is still fine. That’s a lot of meth through it over the years and no failures. I say spray meth with confidence. With my recent tune I pick up 22hp with the meth and this is with a nitrous tune that pulls timing.
