100 wet shot on 2.0 SC
 

gotta couple questions. bit of a nitrous noob. i have an 06 SS/SC with a 2.8, 60's, CAI, and megan catback and a dynotune from SMG Motoring. Going zzp twin charged this summer...but thinking of running nitrous to keep me occupied until then. a guy i know who had his car at SMG blew up his block with a 125 shot after 2 weeks with my mods. so i was thinking of running a 75 or 100 wet shot, and set the timing high so that it only kicked when i was racing someone. but then again...i don't want to blow my motor to bits because it's a DD. thoughts?

I would not do more than a 75. A:no reason B: DD

well i'd obviously wire it to a on/off switch so that i didn't have to deal with NO2 spraying all the time when i'm driving it normally. couple guys i know have it all wired to a switch under his dash so that he can turn it on an doff whenever he pleases. which is what i'd end up doing.

When using N20, you would need a window switch or a way to fab a WOT switch to the peddle so that it comes on at WOT only. You do not want nitrous to come on at partial throttle. Also, I am not sure if you had a typo above, but you want to retard timing 2* for every 50hp in the shot. If you advance timing, you do not compensate for the increased compression that nitrous provides. To me, it doesn't seem worth it for all of the efforts needed to keep everything in a safe range. At a minimum you would need 2 hours to install everything, a tune to retard the timing and add more fuel to keep it safe and somewhere to test it out a few times to make sure that you don't end up with detonation.

If it is your daily driver, personally I wouldn't spray it. I would suck to have a payment on something that is blown up.

i don't have payments on it. it's mine. and fred down at SMG is the guy who does all my performance work. so i'd have him install it and hide everything. and then we'd throw it on the dyno and do a few pulls with the nitrous spraying so that we could tap into the air/fuel and all that good stuff to pin point where to get the best power gains. he's done it before so i trust him....then again the guy who did it blew his motor apart...sooooo yea idk we'll see i guess. i gotta find a kit i like and such.

50-60 shot. safe and you will be happy with the results

agreed you must understand that on a forced induction car nitrous compresses MUCH MORE, LIKE ALMOST DOUBLE!!!

So if you were to put a 50hp shot on your s/c cobalt you would be close to pushing and extra 80-100hp, not 50hp!

stick with a 50 shot you will be amazed at the the gains and your bottle will last longer! any nitrous questions feel free to pm me i have had it on mast last 3 dailies except my ss/tc and my Audi

the only reason the kid blew his block was cuz he powershifted it.
be smart about it and you wont have any problems

stick with a 50 or 75 shot... dont push your luck if its your dd

a little more. not 30-50 extra just because we are boosted. i have noticed them instead of adding 50 crank hp(which is what nitrous shots are rated at), they do ~50whp

I have been running a 100 shot for about a month now and I have prety much the same mods as you except im on a 2.9. Nitrous done right can be very safe. And if you dont want to spend the money on a window switch just hook up a push-button, thats what i use and it works great.

Where's blazin when you need him? lol He is the nitrous whore of this site lol

75 shot is pretty nice imo.

ya this kid needs all the details, he went through like 8 bottles in 2 weeks and the only reason he had a probelm was power shifting the bitch at the track... nitrous doesnt cut off like fuel it will just keep the motor going by itself in that situation... thats how you blow up motors.

anyway just talk to fred the guy is incredible with this stuff.

fixed

He sold out.

Nitrous is fun.

Start with a well tuned 50 shot and see how you feel. If you need more, you can do a 100 shot on the stock block, but if you are trying to run smaller pullies and so on, you will have to back the tune down accordingly.

07 2.0l Cobalt SC Nitrous???
 

I have few questions about nitrous can anyone help? What is the best way to run 50 shot with the supercharger
