Nitrous Oxide - Nitrous why you should use it!

Well I am not happy with this 5177 dry nitrous kit at all! I think I am going to throw it in the trash ;) !!

We went to the track last night and tested on a ramp controlled 125 HP shot leaving at 50% from the line. Came out with my new best 60 foot and almost tied within one hundredth of a second my best 1/8 mile run using a full 125 HP shot from the launch.

The big difference is until last night my best effort was in -600 DA and last night the DA was somewhere above +1,500!

Here is the breakdown of the slip – 60 foot 1.279, ET 6.276, MPH 111.175 not bad at all for outdated equipment on a little 346 CI LS!!

Nice pass. When are you going to up the shot on that thing?

Thanks! I will be doing that on my next outing.

I wanted to see if we could get the car in the 20's at the local 1/8 mile track that we go to on a 125 HP shot controlled since my best was in the mid 30's there last year. If it will run in the 20's there on TNT night leaving at only 50% flat lined for a few hundredths and then ramped to 100% taking over a second the Fromy should be in the teens on a prepped track with all slick cars running on it. Not saying the track was not working off the line because as I have already stated I now have a new best 60 foot of 1.279 and it felt good riding this 3,320 lb Formy out of the gate on that run! Since it was Friday the 13th I decided to be very happy with the results and head home for the night.

I will be changing the plugs to a colder plug and seeing what this little old 346 engine can do! There is no doubt the car and drive train combo is working very well. I have a few more adjustments to make and it will be ready. If we see could results which I believe we will I thinking about getting bold and adding a second stage of nitrous. Well if you call a 250 HP shot of nitrous bold! Carter01 has already gone way past that with his stock long block!!

I do not want to get to crazy and end up having to carrying 6 nitrous bottles with me when I go racing. One extra 15 lb bottle is good for now!

i pretty much had my 125 shot dialed in right. Sometimes it would hit hard and sometimes not even at 900-950 bottle pressure. Ive gone to a wet now and as long as the bottle pressure is there its the same pretty much every time.

Huh what do you mean?

On the dry shot it would hit hard sometimes and sometimes it would be a soft hit. With the same bottle pressure and same A/F. On the wet system it hits hard everytime and is consistant in the way it feel as it accelerates. Plus most companies on WET systems when they say 125hp jetting its usually rates at the wheels the dry systems are not rated at the wheels.

Built bottom end = 350 shot minimum in my world! lol...

Can't wait to see the results on a 250 shot, if you can keep the frontend down she will fly!!!

if you dont keep the front end down, she'll be flying... ok i know what you meant.

Carter01 how many bottles do you take with you to the track?

I have a 15lb bottle now, but I am going to need at least another 15lb bottle at the minimum and maybe another 10lb bottle also.

N2O sounds like alotta fun.

I have a 15lb bottle now, but I am going to need at least another 15lb bottle at the minimum and maybe another 10lb bottle also.

I have 2 10 lb bottles and usually can make 4 hits on the 300 shot and still be consistent. If I'm trying something really different and need to make several passes i will borrow one.

Also try filling them to 9lbs instead of 10lbs. It will help with consistency.

I have never had that problem on a dry shot you must have been having problems with your solenoids. The problem I have is keeping the car down. So that makes me feel even better 1.27 60 foot and a 6.27 on a 107 HP shot to the wheels I like it for sure!

I am working on a game plan, you have given me much inspiration seeing how well you have been able to move your car down the track!

When carters block goes i heard its going to be shown on ripleys believe it or not lol, but the way that thing runs i dont see the block going anytime soon, i still cant believe how well that car runs

Thanks for the filling tip! I had heard that before somewhere also that overfilling them really won't do anything but hurt your bottle pressure consistency.

I think I am going to try and stick with 15lb bottles, but at this point it's whatever deal I can find!

N2racing your car is running really good! Now up that shot!

Nah, I'm not ready for Ripleys just yet. Still haven't hit it with 400 but when I do i will let you know :thumb:

I went back and looked over the time slips and it appears the nitrous runs are pretty consistent. The only problem was my shifting since it was my first outing I was having problems getting my shifts points correct.

1.366/6.395/110.523 – Bumped limiter on 1-2 shift
1.338/6.378/109.686 – Early on my 2-3 shift
1.311/6.365/110.674 – Very late on 1-2 shift
1.347/6.315/111.167 - Hit both shifts perfect

Changed controller setting and gave it one more try.

1.279 /6.276/111.175 – Hit both shifts perfect again and gained a new best.

All runs occurred in less than a 1 hour time slot. The results from nitrous and why you should use it that is as long as you can shift correctly :)!

400 HP is that one or two shots?

I will make the drive to see what happens when those pills are put in the car and the transbrake is released :nod:

One, no progressive, no limiters.

You will have a text sir before I go!

I like all this nitrous talk

One, no progressive, no limiters.

When you say no limiters what do you mean?

He doesn't use travel limiters on the front, controls it with the front shock

That is what I figured, but I could of sworn I read somewhere once from him that he did use limiters. Oh well he knows his car a little better than me I would think!:)

most ppl call using nitrous cheating because you have to refill it. i dont think so. the funny part, its the same ones that call it NAWZ :bang:

Sorry Fbodyjunkie06, a little slow on the response.

Cam is correct, control the launch with the shocks and timing on the hit. Only wish I had software and computer to control how soon to ramp back in the timing but for now I will just keep it low.

I too wish we had a launch retard function where we could pull a set amount of degrees out and have it ramp that amount of timing back into the motor over a set time and not by rpm.

At least with a nitrous motor it's a little easier to predict what rpm the power is going to come in at.

I just wish we had more than 400rpm sweep in between timing cells and that they were 100rpm intervals. That would give us non progressive guys a way to really fine tune things. Power can change 200ft+. lb of torque in 400rpm on nitrous.

Which controller are you using and what settings are working best for you?

You gonna spray your's speed tigger?

Your car and current stall should love the spray.

I have been considering it. It does not feel fast to me anymore.

Spray it!

A single stage 150-200 shot would put you into the low 6's with the right traction and chassis tune-up.

yeah to those people i just tell them its a power adder just like your turbo/supercharger. just cheaper and you have to refill it.

if they say i can only beat them on spray i say they can only beat me with boost.

I don't that I want to throw 200 at my junkyard motor and stock cast pistons.

I was going to start with a hundred shot and maybe go to 150 after the euphoria of going into the 10s wears off.

If you are asking me about the controller I am using a FJO and it is very easy to use and works perfect!

Carter is rubbing off on me I am thinking about hitting this old bird with two stages and let it fly! I have two 15 lb bottles anyway I may as well use them!! :burn:

N2

I bet if you hit it with another 125 as a second stage about .2 or .3 after the first stage ramp ends it will go 6.0's if not 5.90's!

I am thinking to hit the second stage of nitrous after the 1-2 shift occurs!

Just got my 2012 Chevy High Performance Nationals Flyer in the mail and they put my Formula on the front cover. Pretty cool!

Thanks to the organizer!

nice pass i love me some nawzzz

Giving it all up and taking the nitrous off! ;)

N2O sounds awesome don't know why folks are such haters of the stuff.
