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.

Oh so now you want to bring up some old stuff! LOL just joking!
The secondaries are food for thought and I already know that Edelbrock probably aren't the best 4 drag racing anyways but it is what it is it's what I got so it's what I've had to deal with. I think the secondaries are opened up by what the motor is basically calling for. I've read a lot about dual carbs of course on the internet and I can't believe all of it but there seem to be quite a specialist talking about 2 600 CFM not being 1200 CFM but actually about 850 to 900 in the end. Explain how it didn't work that way like you would think.
I get what you're saying about the miles per hour I don't even think I picked up any of that. I had some runs better and some runs worse as far as miles per hour, but where I wanted to really pick up any rate was et.
The way I had it calculated I put another three hundred pounds or so in the car with the eight point roll bar all the fish plate the bigger Springs and the Dana vs. The eight and three quarter and frame connectors. in essence I should have slowed down 3 tenths because of the extra 3000 pounds, but I've gained 2 tense in the quarter mile which in my Twisted Brain says I picked up a half a second? And that's again apples and oranges I mean it could be discussed either way and I'm definitely not trying to argue but again just trying to point out how it came to be in my Twisted Brain. I seem to still be moving forward which is a good thing. from the car I brought home two years ago I'm feeling pretty good. In the end I will see what I can do about making sure the secondaries are opening. I'm not exactly sure how to test that?? thank you for the insight. And ideas....
