spark plugs really can't net you horsepower. that is like me telling you use my oil i made myself that is fully synthetic and looks green and it will give you all your hp and gain more than other fully synthetic oils. /fail

if you are smart and advertise something right you can get a bunch of idiots to follow and claim it works and then hire people to promote it. the smart people sit back and laugh knowing you can't gain hp off oil.

on a stock s/c cobalt. gas will not give gain you hp. it is a stock tune and regular vs v-power there is no difference. oil's there is no difference. spark plugs there is no difference. if u were however to say how you gap them can make a difference i'll let you slide on that one.

however if you take 2 different spark plugs both 1step colder and gap them the same. or close your not going to gain whp from one or the other. every person has there own say in these things and that is how i feel about the question you asked. 5hp of spark plugs damn.... i am going to buy them plus whatever else that company sells cause damn it must give me power.

 

can i run 2 step colder plugs with a nitrous/meth setup? im running one steps now, but im gettin crazy misfires.

 

if you're misfiring I don't think a step colder is gonna fix the issue. maybe try closing up the gap on those plugs?

colder plugs wouldn't hurt but unless you're having issues controlling detonation its likely not necessary

 

I was looking at the dyno tune window switch and it says you might need a tach adapter and i was wondering if anyone knew anything about this or if it is needed

 

tach adapter is not needed, if you can set the window switch to 2 cyl mode then you are fine

 

You should really rethink the "Optional" tag you have on a blow down tube. I know you posted that "some" tracks require it, but that's not really not convincing. A blow tube is an absolute inside a car, including the trunk, whether or not you're on a track or parked at home. I'm sure you've seen threads (like idunn's thread) about bottles exploding from excess pressure. A blow down tube can save your car and your life. It's way cheaper to refill a bottle of nitrous than it is to repair the damage an exploded bottle can cause. They're like $30, if that. Excuse the rant, this was just meant to be a simple suggestion.

Almost forgot about the second part. Make sure the blow down tube you order is made it fit your bottle. They are not all the same.

 

Lot of misinformation on the whole blow down tube deal.

A blow down tube is required when the bottle will be stored in either a fast back car or in the passenger cabin. This is do to the fact if the pressure disk ruptures the nitrous will release into the cabin to much nitrous will kill a person. If the bottle is in a trunk that is sealed or seperate from the cabin no blow down tube is required.

The exploding bottles is due to people destroying the structural integrity of the metal by torching the bottle.
In this case no blowdown tube will save you.
As the pressure is below the break point of the pressure disk but still higher than the fatigued metal can take so the whole bottle explodes not the pressure disk. Which causes the pics you've seen.

 

I don't know the history of that guy's bottle. What I do know, is that unless your bottle is mounted in the back of pickup trunk or some other open area you need to run a blowdown tube. The trunk or hatch area of a car is not sealed off from the cabin are. Sure there should be a seal round the trunk to keep water from coming in, but that doesn't stop the air in the trunk from spreading through the rest of the interior of your car. Try this, stick a disgusting bag of trash in one of your friends' trunk and tell how long before you start to smell it.

Cliffs: Get a blowdown tube.

 

would i have to do any timing wit a 35 shot

 

awesome write up

 

I would suggest pulling 1 degree but if you can't, there's no point in worrying about it.

 

Awesome write up man, got me thinking about buying a system now hmm....

 

Ok so i'm considering buying a nitrous kit for my car tomorrow. I have a 2005 SS/SC and my only mods are Injen CAI, 2.5 catback with no cat. Now my question is, Can i run a 50 wet shot with my current setup if i just get 1 step colder plugs? Your advice is greatly appreciated

 

1 step colder for a 50shot
whenever you go colder, your car will make *slightly* less power while not under n2o

 

Ok thanks, so I'm picking up the kit tomorrow morning and ill get the plugs and see how she goes i guess haha

 

i believe the general rule is 1 step colder per 50 shot, so if 2.2's want to run a 75-90shot they should run 2 steps colder

my ss/sc didnt feel any slower without spray with 1 step colder, but im sure it would dyno a couple less hp /shrug

 

i think i might run a 50 shot... hmm... we'll see

 

lots of ss/sc's have run a 50shot just fine, according to GM the engine can handle 35shot just fine, but of course they're being cautious. same with 2.2, they claim a 75 shot, but ive seen a couple cars run a 90-100 shot and havent had issues

 

good write up

 

This is an awesome write up. Does anyone have pictures of their install or finished set-up?

Back in the day I ran a Zex dry-kit on a built 2.2 Cavalier. Melted the pistons and bent every valve with a very large shot. Nitrous is crazy fun, but expensive.

 

sweet write up

 

Pictures would be cool ... pun intended

 

drivin a 2.4...putting a wet 75 shot on...just wanted to make sure all i needed was 1 step colder plugs...do i actually need to go get it tuned on a dyno???...also does anyone know of places in virginia beach area who fill nitrous?

 

you just need 1step colder, 2 would be better for a 75shot but with a 2step you'll see a bit less performance when not on the n2o

as far as filling it, no idea.. but look around for small race/performance shops

 

Do i dare run nitrous on a stock ss. and if i can what size shot do i use.
