You may try changing your nitrous jet also to see if you still only pick up 50.

 

Oh! I was thinking you were at 10,000' or something!

I'd love to go to one of these sometime, but it's a long drive just to have my *** booted off the track after my first run. I not only don't have a roll cage, but I drive a convertible!

 

I have the same converter and 3.73 gears. I got ~75 rwhp from a 75 shot on the dyno. I recently bumped up to a 100 shot and if the seat-of-the-pants difference is any indication, I'm certain to have picked up close to another 25 horses. I'll know for sure when I get a chance to redyno the car.

 

I'm in the same boat. My plan is to use my first 2 runs to figure how to get some traction and run to the 1/8th mile marker and back off.

If I can hook up on the 3rd run, keep her wot and see what happens.

I would expect with "reasonable traction" to be an unwanted visitor!

Would like o put her to bed "knowing" what it will run.

 

Sounds like a plan to me! Good luck with it, amigo!

P.S.- If you plan you use your Nittos, air them down to ~16 psi and REALLY heat them up. If I do a short burnout, I never hook well.

 

The NX guys do this as a job, not a hobby/passion like us normal gear heads.
Try the .028 and see if it's better, you'll feel it if that's it, and it's not a big enough change to hurt anything. So you have a before and after dyno print out?

Robert,

I didnt get a dyno sheet on the nitrous run because I didnt ask for one. I wasnt there for a n20 dyno run. Just did it out of curiosity.

I will email the guys and see if they can email me a copy. That won't be until monday though.

When I get it, someone is gonna have ta show me how to post it.

Thanks

 

Weather and/or air density "should" not effect the nitrous part of the run. That's why I went to it instead of a supercharger. My car does not care about outside temp when I am on the juice as much as a supercharged car does. My air temp is cooled by the juice, not like a supercharger that has to pull in hot air. So I don't believe outside temp is a real factor for this problem. I personally would check the items I listed first BEFORE playing jet doctor. Better safe then sorry. I hope some of the NX guys jump in here and shed some light on the low numbers. As you said "2 for 2" low, I have "3 for 3" normal. Very strange.
You did get the medical grade nitrous, that way if the numbers aren't there you can just inhale it!!!!
Someone has to have a real answer....

 

wow,that sucks. my t.n.t kit gave me 141hp on a 150 shot on a mustang dyno in 100deg heat.

 

Thanks for all the info guys. Here is my plan...

1) Check to make sure there is no blockage near the jets.

2) I'm going to swap out plugs to a plug not so far on the cold side. (these plugs, AR12, are real cold and I was trying to be "over" safe. Will go to a "reasonable plug, AR23. (note, I can not run standered length plugs in my heads. They have been macined to take a shorter reach (.300 less) plug) If some can cross a TR& or such to a plug like this, let me know.

3) Swap to the 28 fuel jet.

4) Get the bottle to 1050.

5) Hope all stays together.

Will try and get it dynoed at a local shop. (One I have never been to!)

This of course ONLY if this freakin rain stops !!!!!!!!!!!!!!!!!!!!!!!

I will post results.

Thanks

PS... I use medical grade nitrous!

 

I have read/heard that a big stall will affect Hp/TQ when it comes to using N2O. If this is a false statement someone please speak up.

I had to use different jets (other than the chart) to get the 100 and 150 to the rearwheels.

If you have a problem with your NX instead of complaining about it in a post, try a PM to NXRicky or call NX and see what they say. They have some of the best customer service. You might also try Nitro dave

 

30thz,

It is my right to make post about something I have over $1500 invested in and it DOESN'T do what is advertized..

Tell me, When you buy a kit, it doesnt come with a warmer. (That package was another $300 and yes I bought it) How would you get 1050psi without it?? Aint gonna happen .. SOOOOOOOOO..

How would you get 100 on a 100 shot with 900psi?? (That was my bottle pressure after it was filled yesterday..

HMMMMMMMMM

 

I don't think "right" is the correct word here. I don't know about anyone else but that post seemed pretty rude. Either way, when I dynoed a 200 shot (NX) I only saw 103 RWHP from it. I don't know why it did that and was pretty pissed, but with my next dyno visit, after having changed NOTHING, the graph showed a 205 RWHP gain. The only difference was the first time it was a VERY rainy day with 70+% humidity. I blame it on the rain, which is probably false. Does it feel like a 50 shot? If you barely feel it on the street/track, it's probably a 50 shot.

Somebody,

Sorry,,, As a member of this board I have as much "right" as anyone else to post what I feel is problem with something I have spent serious money on. I am not using profanity as many others do. I am stating facts, not fiction and answer other peoples post as respectfully as others answer mine.

Please understand,, As I said in a previous post, I will make adjustments to my setup to try and see if things change. In all honesty, I should not have to. You should get what you pay for.. Plain and simple..

Only those who have their cars dynoed really know if the get what the pay for..

JMHO

 

I believe it should be "Only those that run their cars at the strip really know if they get what they pay for.."

Don't get rapped around dyno numbers, especially when it comes to nitrous on the dyno. I had a dyno tech tell me everything from my bottle pressure was to low, my trans was going to **** ( and that was the day after I got it back from being rebiult) and when I took it to another dyno it was nothing more that a simple jet change. Not all dynotechs know what they are doing.

You have to remember not all cars are the same. Fuel pressure, bottle pressure all this effects the hp/tq. Good luck with it and keep us update you have me curious to know what it is.

 

I must agree with this statement. I've seen more than one "dyno queen" fall on its face at the drag strip while other cars (my own included) that never make huge numbers on the dyno, perform surprisingly well at the track.

Bottle pressure can make a big difference on the dyno and at the drag strip. NX systems are designed to be used at ~1050 psi. Spraying at 900 psi will deleteriously affect output and performance.

 

My car only did a 50 shot on 100 shot, but my motor was in the process of blowing up when I dynoed, so it wasn't an acurate number. When I get a new 346 in there next week I will dyno it again and post results.

BTW, I normally dyno 383/400+ RWTQ/RWHP and have run several 7.15's at 95 mph in the 1/8th and 11.42 at 122.58 MPH in the 1/4 Mile and that was on a poor 60'. Dyno Queens never tell the true story, but the track will.

There is somethign wrong, that's for sure. 100 shot should give you 100 shot, or close to it.

Good Luck

 

If this is the case (and it seems to be factual), why would a company sell a kit without a bottle warmer? You need to heat the bottle to get pressure that high.

The kit alone will not get the advertized power. Do you feel this is an accurate statement?

And by the way, I totally agree the track is where numbers are put to rest!!

 

It's a basic kit. The GenX1 And GenX2 are upgrades to the vehicle specific kits. Not everyone uses a heater some use pusher system. One thing to remember is the base kit doesn't come with safety equimpment either but it's a smart thing to add.

Yes, to your statement the Basic kit alone does not come with everything need.

 

Ok, What is a pusher kit? How does it operate?

Thanks
