very interesting thread, i am the guy with both kits on my truck.

FIRST i must say i have a jlp motor in my truck, a jdm blower and exhaust on my truck, and a psp tune in my truck.

so i am loyal to NO ONE!!!!

on the street the rt kit has worked flawless for me. it is much smother then the nx kit. i always use it with a bottle heater.

at the track the rt kit boggs off the line, the truck stumbles and sputters.

in my opinion the rt kit needs to have a purge and a bottle heater. as for the nylon lines, they sure make it easy to install

the nozzle on the rt system is a bit cheesy, but the nx nozzle isn't the best either. i run the TNT nozzel on the nx kit.


but the facts are, if im gonna run a big number i need to get out of the hole quicker. and the nx with a purge has done that for me

 

Boy did I miss out being sick for a few days! I'm gonna have to get internet in my bed room!

Peace,

Suavy

 

I think there is to much variance in any of these test to really tell the truth. I dont have much for mods on my truck, but what I do have has come from Sal and the nitrous kit from RaceTested. I have an older Autologic chip from Sal. Only a street tune on it. It is fairly rich and I opted to keep it this way. I have been a mechanic for 10 years and always stick to basics when doing things. I believe in keeping it simple. I am running a 2 to 1 jet ratio on top of a rich tune. On the nitrous (75shot jetting) I am knocking a full sec off my boost only ET's. I am quite sure there is alot power being left on the table with the current setup. I will get it on the dyno soon to see what kind of air fuel ratios im seeing with this setup. One could only assume that it is pig rich. I will gather this data soon and send to Sal as Im looking to upgrade to the Xcal 2 and a true nitrous tune. Then we will see what I can really get out of this setup. This has also been without the use of a bottle heater. Kit has been extremely consistant for me as well with only my hundreth column changing in between runs. I think the best thing to do is to work together to solve the problems. As you can see some have had great results. We just need to determine what the variable is that is changing the results between users. Im sure that everyone that has installed these kits does not have basic automotive knowledge. A good solid basic install goes along way. I have seen many a motor lossed due to improper or poor installation. Just to many variables out there to point the finger guys. Hope this can be worked out for both parties benifit. Will contact you soon Sal for an Xcal and some new tunes!

 

Awesome results my RT Brothers
AND YOU WILL NEVER HEAR ME SAY DIFFERANT
I love Denny and their Products, I was the one who sold everyone on how smooooooth the delivery is, how awesome the quality and workmanship is, D's flawless customer service, AND how consistant my results have been with it.
Agree Agree Agree
I say it everytime 2 yrs and 22 runs to get "ONE" 11 out of the Zex kit, but
Straight out of the box, 3 diff days, and every run on the RT kit has been an 11. Including one on the new motor at FFW this season before getting rained out. This system has worked flawless for me, I Love it.

That is not what this is about,
BTW I resent that remark, great time and effort went into my installation,
I agree the heat played a MAJOR part in what happen at NMRA, but you guys were there and saw ALL MY lines turn to soft mushy rubber, as for the one that exploded ? I feel it was far enough away from direct heat.

If any line was too close to the egr, it was the braided fuel line you see.
The n20 line comes off blue, and you cant even see it in this picture


What this is about is a problem that seems to have developed with the use of the Kit on L's that have higher power levels, (and yes more boost than say a std 4lb pulley). On a 400 HP L it seems to perform flawless, but for some reason on a 500 HP L (or above), there seems to be a major issue ??? Sal has giving feedback on what he feels would help, Denny feels too strongly about the system to seem to want to try something diff, and here we are (the customers) wondering what to try next ???

For the record, SAL TOLD YOU HE HEATED THE TANK, of course I have a heater.

In Marks (and maybe other cases) I agree the nozzle and Plate set up is the cause, it's simply too short.


HENCE THE REASON MINE IS IN THE UPPER


I think we have two issues, one the lg of the nozzle especially for plate users,
and two the lower pressure RT uses (@300lbs out of the solenoid) for the higher hp L's

Since I do have braided lines and appear to have enough nozzle sticking through, I believe it's pressure related vs the extra boost

 

If our kit is bogging out of the hole for you then it's most likely to rich. Have you leaned out the fuel side? The 2:1 jet ratio we start everyone off at has been explained as a safe RICH setting. As people have seen sometimes it works fine but if not then lean it out.

 

Mark,
I am all about helping you out and will. I fully admitted our plate has some problems that were created in the manufacturing process which I did not notice as the prototype was built fine. The injector can't protrude into the airflow correctly so MOST likely you are spraying have the nitrous into a wall if there is not a perfect port match or against the plate hole itself. I talked to my CNC guy yesterday and am having a new plates made with modifications to correct any problems.

How this one thing leads to Sal saying the kits just don't perform is beyond me as many people have posted differently.

Sals excuse for not calling me for help is ridiculous. The kits come with a Lifetime warranty and Lifetime of technical support which I have never denied anyone and WE know the products best. Why would you not utilize this? All I can see is Mark getting screwed. If there were problems I would have been happy to send new parts or whatever, but don't send Mark home not running properly and say you knew I would have been no help when you never tried!

God forbid the great Sal could not make a nitrous kit make good power and needed some assistance.

 

Bottle Heaters again, I explained this above. There are so many on the market already we don't care to make it a priority as it's not an area we can improve on much besides a better pressure switch and maybe cleaner set-up. Go and and buy any bottle heater, they all are effective. You don't need to wait for us to offer one and I never said you don't need one. I said in the past that you can increase the nitrous jet to make up for the loss of pressure and a bottle heater is not mandatory.

Injector - Our's is one of the highest flowing compared to most standard ones. The crossfire can flow around 200hp and our venom 300hp as the design is simpler. This isn't a beauty pageant but if you want the best function you are not going to get it from the typical nozzle as I have explained above. Most nozzles have the same dsign where the nitrous blows around the fuel shrouding it initially and providing poor dsitribution. Ours(CROSSFIRE) sprays across the fuel instantly and we'll have slow motion video in the future to show the differences.

Rob,
Your comments about the pressure not being high enough at the injector are not correct and we have been over this. How much presure do you think needs to be created to inject nitrous? Nitrous is under high pressure as it's compressed to keep a liquid form, not to increase speed and get to the cylinders quicker for more power. To much pressure actually causes reversion as the nitrous can hit a valve head and bounce back. This is common in direct port applications.

 

Great Thread . We should sticky this. Lot's of good info here....I am really digging this one... .


Rocks

 

When Sal went to do the original run last Wednesday I believe, the bottle was empty because of the valve leak. Sal doesn't deal nitrous, so he had to get the bottle filled. I believe he had it back Thursday night filled. Now I can't defend that he waited until Tuesday ( I believe) to dyno it again. At that point, we had no time to troubleshoot things. If we had a few more days, maybe some things could have been tried. That is the past and there is enough "blame" to go around - I only care about finding the issue and fixing it.

I understand that you feel attacked and have to respond, but this isn't helpful.

-Mark

 

man racetested you are making yourself look like a little crybaby panzy, i would stop before you dig the grave any deeper.

Doesn't the saying go something like the first to defend themselves is the first wrong. The other side to the story has admitted some of his faults but you are still standing there like you are the almighty god. Open up your mind and your business will grow.

 

Mark,
You are right and I apologize.

I am very defensive which is driven by passion and hard work in the things I do.

 

wow......wheres jamie ?? I'm sure he'd be all over this thread......I personnally have and love my NX kit. It took my lil stock block 12psi truck to a 12.3@110 with a 1.89 60 ft.....before the nitrous I cut 1.6s and was running 12.6s so if I could get the same 60 I have no doubt in my mind I'm goin 11s. And for a truck with a 2# pulley, TB, catback and 75shot I feel makin 446/556 at the tires on pump gas is mighty impressive. Also, to top it all off, Sal is the one who tuned it, and it took him all of I believe 2pulls so the man def knows how to tune and set up a truck to run HARD. Take it for what you want, I considered jumping to a RT kit as well, but thankfully I held off to see more results and I wasnt that impressed. For now, my old NX kit is just what I need.

 

Can you explain as I was the one who admitted our plate has faults and aided in Marks poor results?

An open mind works both ways. But this is also a matter of right and wrong based on facts. Comments were made and I have addressed every comment as to why they are not right based of extensive knowledge. Are you going to ignore facts based on loyalty towards another? Sal assumed he knew better which is not true. If I thought there was some substance, then I would have said "good point we'll look into it" as we always give everyone that respect. BUT when years and thousands of hours have been invested that proved a suggestion wrong years ago then NO we aren't going to say "you are right" as we know you aren't and I mentioned why. Now I have not heard anything technical in return to prove us wrong at all. I'm very open to why we are wrong but you better have facts based off extensive research like we do and not just a few childish comments.

 

And we have done the same and better which was mentioned in several posts on here?

 

As far as the "purge" question that pops up even after being addressed.

I have always offered a purge for "braided" line use. The nylon does not need purging for optimal performance but if someone doesn't believe us then by all means spend $250 with us and buy a purge. I'm telling people they don't need to spend the money which I would think is looked at as honest. Why would we deter people from sales and give up perfomance to make ourselves look bad by not selling purge kits when we have them and are needed?

I'm not perfect and always right but where did we go wrong here?
