I have a 2018 Sierra 6.2 with Kooks headers, Kooks cats and K&N CAI. I've been thinking about installing a Whipple or a Procharger but I'm considering nitrous too. I'm looking at a Nitrous Express 20936 kit. I just want the extra occasionally and I'm concerned that the supercharger noise will be annoying. Anyone using nitrous on their similar truck?

The 6.2 loves nitrous, not many trucks run it. Check out camaro and vette forums. You have the same motor and trans

I have ran nitrous on trucks before and just don't think it's a good option, burnt many of pistons. I run the Magnuson tvs2300 supercharger and meth, consider it a lot better option. Plus who doesn't like the sound of a supercharger.

Guy on the camaro forums runs like a 150-200 shot on stock motor and stock fuel, runs 10’s at like 135mph. Says he’s been doing it non-stop for a year. He’s in shock out how nitrous friendly the 6.2 is.

With just bolt on' s and a decent tune, and no nitrous you can get into 10s in a Camero, so it's just not worth it. Now with a charger and meth I have seen 9's. Even just charger and a E85 tune been high 9's. Now it also comes down to money and what all you doing. Nitrous and the whole setup is cheap, but it's a one trick option. What I mean is if you going to do back to back to back runs at a strip with call outs then you going to have issues. Also if you want extra for towing and stuff like that then it does nothing for you. A charger is better at all that. The only way to safely get the most out of nitrous is heavy internal mods.

This is false by a long shot.  no way in hell, a bolt on Camaro SS with no nos, sc, or turbo is in the 10s.  especially with the stock cam.  I know this thread is old, but I stumbled on it looking for something else.  just replying so that other people doing their research can get the facts.

I knew a few guys in low compression days that ran only nitrous in their otherwise stock vehicles. It was cheep fun as long as you were reasonable with the shot.

I have run more 15lb bottles of N2O than I'd like to admit on my LT1 powered Formula Firebird.  Many back-to-back-to-back runs without an issue.  

 

I'd feel totally fine doing a 150 wet shot on these motors.  I'm not sure how well the fuel distributes on the L83 and L86 intakes, but would consider a 200 shot with E85 or perhaps a dedicated meth pump/tank.  Just keep your RPM window in the 3500 - 100 less than redline.  

 

Nitrous for towing...ehh, no thanks.  Also, racing full size half ton trucks, not really feeling that either.

No, Somebody on Cam*ro6.com just did it with the time slips to prove it. 10.70's with a 8speed ,bolt-ons and a drag pack tire set up. Had a 6.80 or .90 at 99~101 mph trap speed in the 1/8th as well. super impressive. might have been on E85.

 

The new GM stuff when modded intelligently puts out big time, amazing performance value. The trucks are no different, literally. Just choose the right mods and pick up big power. Just the overall drivetrain weight will rob about 40~50 rwhp or more over the cars. The built LT-1's are running faster than a lot of bolt on LT4's. The LT4 just has soo much torque management, people have not dialed in how to easily remove it, or all of it, kinda like the trucks. A lot of warranty protection/reduction of liability on GM's part.

 

I'm a believer in the Gen5.  You can make power with soo many different recipes, just not old tired and true, have to focus on removing restrictions & capitalizing on the engines breathing potential to make big power.

 

a vendor on cam6 has a new 4cylinder turbo running 10's as well, hard to believe, but true getting close to 600hp out of the turbo (have no idea what mods were done). I believe it because 10 years ago they had 500hp 2.0L ecotecs.

I hate to be the bearer of bad news but there's no way he did that without at least internal mods like a cam/head package, supercharger, turbo, or nitrous.  the new z06 with 650hp ran a 10.9 and its several hundred pounds lighter.  I had a head/cam 05 vette that didn't run that fast (I know LS2) but my brother has a 08 Z06 (7.0L) with a huge cam/heads with all the supporting mods and tuned by Vengenance racing (laid down 650 to the wheels) and ran low 10s.  no way a bolt on Camaro without some major mods ran 10.7.  are you saying the Camaro can pick up 200hp from bolt ons?  lol apples to apples, the 2018 ZL1 Camaro with 650hp ran 11.7 @124.  so, I don't know that all this person had done to their Camaro to run 10.7s but it was obviously a lot.

sure.  curious if the op ever went with nitrous.  thinking about using it on my truck until I throw a LSA supercharger on.  just wondering how much of a shot is good without running a dedicated fuel cell.  also, not sure if I need bigger injectors since I'm already running a cam.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
