Nitrous on a vette

 

I was wondering about this as well, well what is the best kit. what kind do you have?

 

my zex wet kit came in today. results will follow.

 

I can answer that

on my stock ls6 (cartek clutch) with a 150 shot i ran 127 in the 1/4 11.51 ..MPH are good for 10's.. the car in the street was a monster...
so if you are running 110. look for 124-126 easy ..
I think nickel for nickel NOS is the $hit .

just watch the bottle pressure ..

 

what kit should I get?

 

I had the TNT kit 75-150 jets.

I think they were under rating them so a 150 shot was more like 175..

I would go with a wet system NX express is pretty good and reliable company.

zex has some good saftey features..

 

10.85@128.9, 1.531 with a dual dry on bonestock LS6.

Kit selection is a function of what your looking for. First you have to decide on Dry or Wet. If Wet then you have Nozzle, Plate, Direct Port or the NX MAF kit (They have a NX dry as well now).

Dry, a limiting factor may be the Stock injectors, my 99 I could only spray a 50 shot dry, a 75 shot would go way lean. Other guys with the same injectors were able to get 100-125 out of them (don't know if they were monitoring AFR or not...). Upgraded to 42's and my AFR is spot on, and plenty of room on the duty cycle to go higher.

A little time researching is needed as to your needs. All of the kits will work, when correctly installed. Kit selection can also include how it looks if your interested in showing.

Once you have your kit, you should have a heater or nano as an accessory because nitrous safely works based on safe AFR, so Bottle pressure is very important. Bottle pressure low, you do not get the full shot effect because the car will be rich, bottle pressure to high, and the motor will lean (very bad for the motor).

You will also need ensure you have the fuel pump for it. Stock pump I sprayed to 466 RWHP and had no issues (Stock 300 RWHP N/A). Someone already at 450 or 500 RWHP probably may need a pump.

You will also need to switch to a colder plug TR6's is what most use gapped at .035

A good place to start researching is LS1tech.com Nitrous forum and read through the sticky's.

 

I ran 10.86@129 on a stock motor with longtubes and a DRY 150 shot. With sticky tires you should go a low 11 without issue.

My stock injectors were good to about 475 RWHP. I added some bigger ones for my final numbers of 500/530. Still on the stock pump with no issue. If I do heads/cam I will upgrade the fuel pump.

A 500 RWHP Cobra avg ET would be around 12.teens on street tires and mid-high 11s on stickies. The only reason I don't have one is because they are so heavy. My vette is a second faster with the same HP!

 

sheesh i got about 460 to the wheels now. i guess i have to look at upgrading the fuel pump. I want a 150 shot right now until i get the money to start on a TT setup, love this forum. thanks for the info

 

Have limited experience with N20 but can tell you I love my ZEX wet kit.
It was very easy to install, works great every time, and has built in saftey features. If the bottle pressure is low it limits the fuel, so no running rich.
Would always reccomend a window switch and bottle heater, a few extras now can save you thousands later.
Computerized nitrous is a wonderfull thing, if its set up properly!

ran a fastest of 127mph on a 100shot through my nitrous outlet plate kit. that's a 10mph gain over my N/A mph though I have an LS6. you should expect about the same trap with your LS1 and 150shot.

only thing I would do different is run a stand alone with some higher octane. money well invested IMO.

 

To answer your question. NO a 150 shot will not keep you up with 500/550 rwhp.

 

Yes it will, he is asking about a 500/550 terminator..ie 03'04' cobra. Which are heavy as hell. Ted's car walked modded cobra's and he was spraying equivalent of 120 shot. I new you wouldnt keep it stock long man

 

I got big plans for it but for now this will do it cause being slow sucks ......later I will do a Forged bottom end /alky kit /Novi 2000 plus whatever supporting mods I need .....you need to just sell me yours

 

That sounds cool, what kit is it, where can I see that?

I'm wondering what happens on a simple wet kit when your bottle pressure is too low. Do you still get SOME performance gain or do you actually end making less power than N/A because your running rich?

 

With the ZEX kit you will still have an increase in performance, just not as much as you would at full pressure- hence the bottle heater to get more consistent performance.
Here is a link to the kit I'm running.

LOL man i am supposed to get my car back Tues of next week i hope we all need to hang out some

 

must have with nitrous- MSD window switch (On 3k+ off before limiter).
WOT switch (only spraying when WOT if you get out of it its off and get back on it its back on. very good for traction issues), fuel pressure switch (failing fuel pressure, juice off), GOOD bottle heater, nitrous pressure gauge.
