Does anyone has nitrous on the 08+ cobalt ss/TC.... i have a set up at my house but i still dont know if to put it or not....

 

there are a few that have spray on the ss/tc check the drag racing section (top list) for their names and PM them. I will probably be faster that way.

 

well i thnk someone had a dry shot and then blew his motor..his name is on the drag list

 

choko is the guy u want to PM but he will tell u the same thing i am now, u MUST tune for your nitrous if you plan on gaining any peak power with it, he is the guy who blew his motor and he did so to test it's limits before building it up, he will be puttin down some powerful 1/4 mile times come summer.

 

Nitrous newb. I've heard a wet kit is way better option.

 

It is. The shot is a tiny tiny bit smaller between the two, but the safety is much better.

 

how is the shot smaller? you sure about that? a wet kit and a dry kit can use the same jets for the nitrous...the wet kit is safer due to more fuel being avail.

 

Guess I should have clarified.

The shot would be the same, but the power from the shot won't. Dry kits typically produce more hp per the size of the shot vs a wet kit.

 

if u ran a wet kit on it itd be fine I'd have to T into the fuel like before the rail due to direct injection going from 58psi to 1000 my buddy back home in Michigan is thinking about running spray I personally recomend it just always run a richer fuel jet then needed fouling a spark plug is 8$ melting pistons is a lil more ha

 

That's probably because dry kits run more lean than wet kits, running lean is usually more powerful but also a lot more dangerous.

 

go wet shot. its more expensive but you dont have to worry as much as dry. you have to be a dumb dumb to blow your motor with wet shot

 

Stay away from nitrous on a DI motor.......That is just my opinion, no need to look into it more and find out that it really isnt a good idea. Lol. If you do spray it, run a 50 dry shot with a tune, i think you would be fine.

 

The only thing about a wet shot on a DI engine is the engine uses minute fuel to run and when you put the wet shot on you are dumping allot more fuel into the cylinder because it gets it from your fuel port. I was going to do it to mine had the kit and everything in my room but I didnt think it would be safe to put that much fuel into an engine that uses droplets of fuel to run. So I sold the nitrous

I also got on the mazda forums and asked the speed guys and the ansewr I kept getting about nitrous on a DI engine was to many zoom zoom boom sotries, If you were to do any nitrous I would do a dry shot and tune it to get the extra fuel from your injectors, you would run richer normally but probably not much.

 

can a stock ss/tc handle a 50 shot, or do i need to upgrade to forged pistons before i put a kit on?

 

Choko was running a 125 dry shot on his before the tune.

 

i think im gonna get a kit then

 

I am interested in this as well. I am pretty new to nitrous, I know the basics, like wet vs dry, and what N20 basically does.

Now, reading this I had an idea. Running a dry shot, like a 50 shot, could we tune the 90-100% load tables rich, so the nitrous doesn't make us lean? I mean, I wouldn't run my tune pig rich on the street, but only when I was going to shoot. I could tune the map so it gets rich at the RPM the nitrous would start shooting.

Any ideas? this is just a thought thus far, and i haven't had time to think it through yet, so let me know what you guys think!

 

more intrigued as more intel and experience is coming in.

 

My friend was running nitrous on his SS/TC https://www.cobaltss.net/forums/pictures-videos-64/my-ss-tc-action-some-v8-buddies-146312/

 

I need to find someone down here that wants to setup nitrous on a TC, I think it would be a nasty car.

 

I got to thinking about it more and more at work tonight, that i could likely run a 50-75 dry shot fairly easily. The only problem would be the fuel injection window. I think we have about 7ms to inject fuel, and I think I am near 6 or 7 already. This would mean that I could not run as rich as I think I would need to and still keep it safe. If/When we get fuel pressure unlocked in our tuning tables, I know I will be able to tune for it.

See, I was thinking I could run a window switch, and start shooting about 3k rpms, just so I didn't lose all traction, and just tune it pig rich from 3k up at 90-100% load.

I will still ponder this, and possibly, if I can find a good cheap dry shot kit pick one up. Anyone know of any used kits?

 

Biggest downside to that is the car is going to be rich all the time when you are not spraying, which is just costing you power and wasting gas. Go with a wet shot, takes minimally more work to set up, much easier to live with once installed.

 

Yes, but I could reflash when i was not intending to shoot. I would never run it on the street, therefore no need to have that tune. And, when I was shooting, I would be going down the track. Idling around at the track, I could tune to run at stoich. IDK, it was just a thought, mainly considering the way the fuel would be sprayed. DI is so fine of a particle, and this would be a much denser spray, like someone had mentioned earlier, so I was trying to figure out a way around it.

 

**** that, why not use it on the street?

Odds are, second gear is gonna be close to worthless at the track unless you are running DR's or better, so you will really only get to spray through most of 3rd. On the street is where the powerband can really shine on these cars.

The main advantage of the finer DI injection is cleaner burn in easy driving for lower emissions. The evaporative cooling from the fuel going directly into the chamber helps with power output, since it helps control chamber heat and reduce the engines tendency to detonate, but thats about it. Mostly an emissions thing.

 

So, you are saying I would be able to hook better on the street? Lol... w/e.

And why spray on the street? I don't really street race, and if I was, I would be able to reflash in less than 30 seconds. I am not going to drive around with a charged nitrous system at all times. Not only is it dangerous, it is a waste of N2O, because the system will lose pressure eventually.

As for the DI being mostly an emissions thing, I agree. But our engines are so closely monitored for emissions, I am afraid that the extra fuel coming from anywhere BUT the injectors would cause a problem.
