I am leaving town tonight.So ill see you guys monday.Have a good weekend.
Dave

 

Well guys just got back from the track!!!!

N/A
2.1 60 foot
13.1 1/4 mile
107 mph


Spray - 120 pills (VERY VERY VERY traction limted, aka car went nuts when the bottle hit)
2.1 60 foot
8.6 1/8 mile
12.9 1/4 mile
116 mph


Now keep in mind that this was on a non tuned motor with every single bolt on, about 2lbs of nitrous left in a cold *** bottle with no heater. BTW I started to spray around 50 mph in 2nd. Next weekend I am going to add this accumulator, bottle heater, and have a full bottle on some slicks. Hoping for good 11's on the 120 pills, might just have to buy some 140-150 pills!

Then with the semi basicly empty bottle we sprayed down my friends intercooler on his evo and made it run 12.9 with just exhaust.

 

so what would one have to do to get thier kit "up to par"? i have one of the first ones that came out, no accumulator, fragile fuel/N20 lines, and original jets. should i call NX directly or the sponsor i bought the kit from? i would love to run a dp instead of the wet shot i had to get when the NXL didnt work but im worried about how much money ill have to spend on top of what i paid for the kit.

 

I am not reading all the way through the pages of this thread, but, if Ricky could, please test the kit, several times. Say maybe two or three bottles in it before you call it good. Mine worked good for about 2 or 3 bottles, then it went **** up. Needed fuel solenoids replaced, but they werent bad (figure that one out). And testing on a dyno is ok, but what about track testing it also, again, I would run at least three bottles thru it first.

Glad to see there is intrest in fixing any issues.

So a lean spike to 16.0 is considered normal?

 

Can somebody set me straight on this, with direct port dont you always get a lean spike even with an accumaltor unless you are running a seperate fuel system for the nitrous or a return line system. Regardless of whos system you are using.

 

if 16.0 lean spike is normal what would you call my 17.5?

 

Brain said in this thread that no one else had the fuel rail lifting problems that MeanWS6 had. This is not at all true. If you look at the NXL problems thread there were several...5 or 6.. of us that had that problem.

But that is not my real problem with NXL and this kit. I have pulled this quote from their 2004 catalog on page 19:
This was the description I relied on when I decided to purchase the system.

As of now, NXL has defined 6 problems with the kit for which they now have fixes. These fixes only came about after the buyers of the system designed their own fixes, which is direct evidence that the system was defective. Is this "true plug and play performance?" Is a system that comes without the accumulator that is required to fix a possibly engine killing lean spike really "complete" with "all installation hardware?"

I also noticed that nowhere in the catalog description was any mention that this was a "STREET KIT, with the look of a direct port." The catalog states several times that this is a direct port system.

What has NX offered to those of us that have the kit installed on our cars?
We can buy some of the parts at a cost of almost $250 to fix 2 of the problems...
Accumulator 199.99
New Jets 42.79 (for 8 from jegs)


As for the other problems, no fix has been offered for current owners of the kit. Just a reassurance that the kit has been improved for future customers.

In my opinion, NX should either
1) recall the kit and reimburse all current owners their purchase price, or
2) replace all the defective parts and supply current owners with the parts needed to meet thier product description at NX's expense

I guess I should have bought the Noszle system.

 

what he said ^ maybe NX could take back the defective kits and replace them with the "fixed" version

 

A lean spike is just that a spike. The air fuel has to spike, you open a solenoid or two, there is a pressure drop. Lower fuel pressure even for an instant at the injector will show a spike.

 

When the car is runnig at 55-60 psi and you open a solenoid or get a leak there is a pressure drop. This drop will last as long as it takes to fill the lines and achieve back pressure. This is were the accumulator comes in. It helps fill the lines faster than the stock fuel system, (even with an aftermarket) can with the accumulator. So with returnless fuel systems there is no choice but to have a spike. A spike does not hurt engines lean or over rich tune ups do.

 

if its a spike then thats it a spike. As in our graph with and with out accumulator we had a spike hit 18+ without accumulator. The enigne still made the power but had a very noticable hesitaion. With the accumulator 16:1 with no hesitation.

 

Ricky I pm'd you my info.

If/when I get those jets I will put them in and actually hit the dyno.

 

Or another option (which is a win win for them, cause they keep us as NX customers) is to replace the NXL kit with the MAF kit

What are NX's thoughts on this, just curious.

(Also, did anyone else lose NA power after installing the NXL rails, I lost 15RWHP)

 

i lost 20 rwhp na after installing the nxl rails ,the car ran rich a/f in the high 10s with nxl rails ,stock rails a/f was in the 13s

 

Im not saying that you are wrong.But I can not see any way that buy changing the fuel rails that you would run richer than normal or lost HP.Just because you changed the rails the injectors are not going to add anymore fuel.Did you do a plug change also?If so what plugs and what are they gaped at?

250hp jet with 38N, 14F. The engine held together and went way rich. We did install the 12F back into the NXL. The car did not like. Got to see a real lean tune. http://www.nitrousexpress.com/Pages/ls1_nxl_250hp.htm

Dave no changes were made i just replaced my 100 shot wet kit with the nxl kit when i removed the nxk kit and put the 100 shot back it was fine hp came back

 

Rickey that a/f looks good to me on the spray

 

i paid $1300 for my NXL, not $900 like the maf system. i cant badmouth any sponsors here but im not happy with my complete plug and play kit and if i have to fork out more money for it to work right ill do my best to make damn sure everyone knows it .
