Here is a site for nitrous settings. www.coldfusionnitrous.com/nitrous-systems/topic/21-nitrous-calculator.aspx
That calculator is way off The nos-fuel jet sizes are way off for any plate system Also it states 1 82 nos jet will make 300 hp :eek2: Good luck with that lol
Ok if that is not correct then what is the answer. You run nitrous. The calculator says to run a 82 nitrous jet .076 jet for fuel at 6 lbs pres and 950 lbs nitrous pressure, is this correct for fuel jet. I don't care about the 300 hp part I want to know if the jetting is correct against the nitrous jet to fuel jet with bottle pres and fuel pres. Is the starting point correct. I do not think any one is going to try and put 300 hp in a 350 probably more like 75-150 hp. The DP manifold can't take a lot of nitrous because of distribution problems. Looking for facts you should have them tell us how to do it. I can only give what I went through.
I took a look there that is for the serious racer not for us 100 shot users. There were some wiring diagrams that looked good. I just want to put out some general facts so others know what not to do. Like, if you run a bottle heater even though it has a thermostat on it does not mean it will shut off. You have to keep an eye on the pressure gauge and keep it in the 900-1000 psi range. Otherwise if it gets too high you will hear a nice big boom when you hit the throttle the first time. some people have never used the stuff so I am sure some info on this will help.
Great thread start.....I have built and run alot of motors but...am going to try the nitrous and am only as smart as I have read about this....so keep it going !!
Drop the timing 2* for each 50 hp added. The Edelbrock system looked like a good system but I had already had mine at the time. I used Nitrous Works but I do not think that kit is available anymore. What ever kit you get do not use a bottle from another manufacture for the second bottle. I used one from Nos systems and it did not work right, there was a surging problem. I do not know why there may have been something wrong with the bottle. You need two bottles to do this right, just make sure they are the same manufacture. A 125 shot will only give you about 5 good runs down the 1/4 mile.
The best way to go is a TA intake with a Holley 850 on top of this perimeter spray nitrous from Zex: http://www.zex.com/zx/square-flange-perimeter-plate-conversion-kit.html
I must have done something wrong. I entered a 37 nitrous jet and it came up with over 6 million horsepower. Traction might be a problem with that, even at an idle :grin:
You have to enter the correct orifice size in there. On using a different bottle I think there was something wrong with that bottle. I can't see why a different bottle would be a problem, the system should not care where the nitrous comes from. The Zex perimeter spray system looked like a nice system, this would eliminate the spray bar down the middle of the spacer. There used to be a video on this system showing how it works. This way you could use one of those Wilson 4 hole tapered spacers. Those start out as a 4 hole and has a taper that goes into a open style spacer, they have sizes from 1 inch to 2 inches and 1 1/2. I would like to know if this spacer works good because they are not cheap. How do you add pics to the site, I can take some of mine and post it. Going to be 70* out today. I may try to start car today ---------- Post added at 10:38 AM ---------- Previous post was at 10:30 AM ---------- Hey Sean, thanks for posting that. From the looks of it I can use that plate system and my jets will be compatible with the system. ---------- Post added at 10:38 AM ---------- Previous post was at 10:38 AM ----------
Most if not all,nitrous plate systems will like a much larger jet spread than what is currently out there in any catalog or any book Also most of the timing requiremants are way off and telling somebody to take a certain number of degrees out for a given hp number is silly i mean,if you run 10 degrees more base timing on motor than i do,how the heck can a generic amount of timing retard ever be right 4 two combos? you need to look at the overall engine package,and then make a determination on what type of fuel,timing and jet spread you need along with the fact most people have no idea how to read a spark plug correctly,so they tend to get into trouble when the y dont understand what the motor is telling them it wants Oh and perimeter plates seems like a good idea,until you realize the intake pulls the nitrous into whatever cylinder is the happiest,so to speak distributioon wise,so it still wont solve a bad intake design
With the Buick 350 the stock intake has the best distribution compared to the TA or Poston intakes. So it would be nice to use the stock intake with nitrous however with a typical nitrous setup the nitrous is injected at the divider and it works terrible. Same idea with the TA intake as the center divider is in the way. This is where perimeter spray plate is a good idea because it solves the problem for either the stock or aftermarket intakes. I love fogger systems with a nossle for nitrous and additional fuel into each cylinder. The only drawbacks to these systems are the cost, and they are not good for small shots that most people will run on a Buick 350.
Here is a website on reading spark plugs. The first part is for a normal engine. Then go to the bottom of the site page and look for "Detail Plug Pictures Page" There you will find the pictures for nitrous settings. www.dragstuff.com/techarticles/how-to-read-plugs.html
Good stuff there. I wish that Mike Williams would have told us more on how he got his car into the high 11's with out nitrous. What ever happened to Rick Crawford, he always had good input on nitrous. The Q-jet set ups looked nice, they would work good for someone that had a stock intake.
Rick designed the cute little setup I posted.. Don't know. He dropped off the radar. He posted some stuff for sale a while back, but that's the last I've seen of him.. He could probably put a Prius in the 12s.. We need him around...
