Nitrous question for curiosity sakes

Get it tuned up right on the carb FIRST!

You could hit that with a 100-150 shot no problem as long as, like the carb, the tune up is right. Proper fuel pressure and pull timing, about 6-8 degrees to start. Lean out the system til max mph is found then start turning in timing 1 degree at a time until MPH slows down. The jetting on the plates as recommended from the manufacture are DEAD RICH! Any time the fuel jet is same or larger than the n2o jet, it's rich. Rich is as bad or actually worse than lean. If your buddy that runs the fast car is around have him help you pick a jet package. My 2 cents pick you n2o jet and pick a fuel pill 7-10 sizes smaller. Put a .045 n2o jet in, use a .035-.038 fuel jet. Talk with Monte Smith about jetting if you don't believe me.

If you have a wideband A/F sensor that will help too. Hope you know how to read plugs, you'll need it!

Here's a good thread at moparts about this. Big Squeeze is very good and works pretty close with Monte Smith.
