Default At what levels do backfires become a concern?

So I finally got around to getting a hood that'll fit the Holley Hi-Ram, and then I realized, crap, metal intake plus wet nitrous (Nitrous Outlet plate) is generally pause for concern. So my question is, at what shots should I be concerned? Are the lower 100-150 shots nothing to be worried about, or is it the mega 300+ stuff? I was hoping to go no further than 200.

honestly all backfires are not good. Even on low shots you still run plenty of potential for damage. I know prob not the best answer but its true. Ive seen and had plenty cars on the dyno (used to work at a shop) blow up , blow intake manifolds, etc from something as little as a 75

Its all in the tune. You can have a 50 shot backfire if its rich and you have too much timing. Get your air/fuel correct with the correct amount of timing and the correct plug and you will minimize your chances of having a backfire.

"GO GATORS"

...sorry, I just had to do that

I've been chatting with a Holley Dominator installer/tuner about going that route with a dry setup, but there's that whole issue of the factory gauges. So until Holley comes up with a workable solution for those of us with street cars, I may have to just bite the bullet and switch from HP Tuners to EFI Live...like I should've done years ago.
