dual quad nitrous !!?!!

Jason,

A random neuron fired and it went some thing like this:
From back last June when you started this thread:

i must be completely missing something ?!? (Multi-page thread 1 2 3 4 5 ... Last Page)

Till now where you are contemplating Nitrous.

Most of your posts have centered around your own admitted lack luster performance and whats wrong. After additional port work, up sizing valves and adding 1.6 rockers in place of 1.5's, you picked up 1 mph or so. Not a real good return on investment.

The thought that came to mind is..do you know for absolute certainty that the secondaries on your carbs are opening??? May be an off the wall question; don't remember if the question has been asked in the past; didn't take the time to search thru all the reply's and posts generated so far. I be-leave it's a fair question.....your carbs are air valve secondaries, been a very long time since I've been inside one adjusting secondary opening point. If they don't open, you are only running on the primaries and your times kinda reflect only about 600 cfm worth of air in the engine. Think about it, it kinda makes sense, as you did not pick up hardly any mile an hour after your winter building spree. Your combination should lay down much better mph numbers.........I mean the basic pieces are there! I'm not much interested in what the O2 sensor is telling you.......it could still just be telling you what your primaries are doing. Adjust your secondaries to open faster/sooner, probably bog, make it. Then slow them down. It's a tuning excersize.

Just do it.
Good luck.
