Just saw the vid.

Quuuick.

 

Oh ok.....so its no better then just having your own custom tune then basicaly?

 

This.

At any normal Cobalt nitrous levels, you barely have to pull timing anyway. When you're trying to run a 100 shot and have to take out 5-6 degrees of timing from stage maps, well, then you notice it. But it's not bad.

 

Well it gives you a high octane mode and a "separate tune" for the nitrous so your not running around on the same tune even off the bottle with your timing dropped. At least that's how I take it, haven't really looked into it.

You also ran alot of bottles through your SS/SC right? Any problem?

 

A basic 2.8"/50 shot car is downright nasty on the highway, and will beat any M62 setup out there. I ran guys with meth, small pulleys, all kinds of ****, and it wasn't even close. I was still running a stock exhaust manifold too. Well, ported, but whatever. A well-bolted LSJ with a 75 shot would give most TVS cars a run for a lot less money. Hell, you could stay on 42lb injectors and pump gas to do it. I did

Yeah, I blew it up twice, but I was being greedy and pushing the car harder than I knew I should. First time was just too much timing, I was running full stage two maps, a 60-65ish jet with the bottle way overheated, on real tires. Car spun 2nd from a 40 roll, then hooked back up. Popped a piston.

Second time wasn't really the nitrous, I have a feeling it was previous damage from me abusing the car for 6 months with the cracked piston, but it split a sleeve.

I did setup another car on bottle that never had a problem up to a 90 shot, just on my car I took chances.

 

i run 42s a 2.9" and a 50 shot wet, its BEAST

 

With a good tuner keeping it relatively safe is a 75shot really that much harder than a 50 shot?

 

No, you just have to be willing to sacrifice timing on daily driving.

 

Exactly. I switched the nitrous jet out to a .040, and ran it like that for a long time. Hurt a lot of people's feelings on that setup, car was just an absolute animal from a 40 roll.

The main help is from the cooling effect, so the initial gain from ANY nitrous is good. Smaller steps up from there on out. A 50 shot is good for at least 50whp, a 75 really won't gain another 25whp, probably 15-20.

 

All the info you need is posted here;

It's a perfect system if you want to run nitrous.

 

Thanks for the info....im realy considering this.....i just wonder if you have to run a dry kit with it or if its possible to use a wet kit.

 

I'll be running an 'oversized' wet kit on that tune.
Because the Stage 3 tune (unless customized) can only supply enough fuel for a 50, anything larger you need additional fuel. Therefore, the fuel jet just becomes 'make-up' fuel.

Edit:
Alternately, you could just ask Trifecta to turn off the additional fueling, and use the Stage 3 tune for only the timing reduction and trigger.... then you could use a full wet kit.

 

So how does the trigger work?.....i have mine set up now with a push button.

 

It's a combination of an internal PCM trigger, and external switching units.
There is more info on the Stage 3 system, including diagrams, here;

Note that the above is the actual GM Stage 3 manual... the Trifecta tune has some differences, which are discussed in the thread I posted earlier.

 

Blazen and Italianjoe mind posting your whole set-ups? Also at the track did you start spraying 2nd and up?

 

only picture i have of the set-up at the moment

 

ill be installing a kit for a buddy in a few days, im excited for him lol. like super excited haha

 

**** man, so much easier to install a nitrous kit in a cobalt compaired to my 370z, i have no room in my engine bay. Yours is a nice clean setup

 

yeah it was really easy. italianjoe1 installed it for me since i didn't know **** about nitrous at the time

 

lol, i didnt know **** about nitrous either. My gf didnt want me to install it but i kept installing small parts of the kit every once in awhile over the winter. Where is your nitrous management unit at?

 

i got your nitrous management unit right here. lol

 

i didnt mean your activation switch, i ment your MNU that your fuel and nitrous lines go into... this thing..

 

don't have one. fuel line from rail goes into the fuel solenoid and to the nozzle. nitrous line goes from bottle to solenoid to nozzle. everything activated via a toggle switch and actually sprayed with the green button i posted

 

Same way mine is set up
*** a window switch!

 

less **** to fail!
