The G80 isn't the axel, it's the rear end that holds the rear end gears. Actual a 4wd with nitrous will work against him with stock parts due to the weight. He will kill the 4L60E and if anything lasts longer than expected it may be the G80, especially if he's thinking of using a 125 shot.

Many are very opiniated about where to bring in a wet shot vs a dry shot, what size is safe at a dry, so on and so on, but you'll never get a solid answer due to all the different variables. You'll get some good answers but lots different answers. A RCSB 2wd guy vs you in your 5200lb truck will outlast you as far as parts breaking. It's life, you are heavy therefore will take more abuse to get it moving, especially those clutches in that stock car transmission and those rear end gears. Ask any 4wd guy on here. (7 out of 10 doctors say...)

Nitrous Outlet and Harris Speedworks are great to deal with. They'll answer all your questions and lead you in the right direction. But if you don't want to tune, as said above, a wet shot is nice because all you do is change jets on the fuel to get it right. A "small" dry shot doesn't need tuned too much but is still sort of unstable. Spraying the dry shot before your MAF will tell your PCM to add some fuel. A wideband is a nice added feature as well, this way you can keep a better eye on the outcome of your jetting and fueling needs as you get braver on the juice. Better than reading narrow band oxygen sensors.

 

i personally prefer a wet nitrous kit myself, but...i would think if a guy wanted to stay with his stock tune, a dry kit would probably be "safer"...assuming of course the pump and injectors are in good shape. as soon as the nitrous hits the MAF, it starts adding fuel and pulling right? no adjustment necessary i've heard of guys sprayin a 100-125 dry on stock tuning

 

The G80 is the limited slip diff therefore if it were to break it would be an axle problem. Two axles putting the power down means neither will probably ever brake from the nitrous.

Traction weather from one axle or two is harder on the trans just like I said. The trans is going to be the week point. It will probably last quite a wile especially since the spray isn't used all that often.

 

Use what technicality you want, it's a weak point when you go outside the stock set up. Top two items on this site that are broken from power upgrades are the G80 and the 4L60. However I know guys with 500hp and a stock 4L65E, hell even stock rear ends...errr axles, that have been going a long time, I am not saying it will die, just that the chances are high with added power. Statistics don't favor them. Who do you know that gets a 125 shot setup and doesn't use it often anyway? I am not an internet troll trying to argue with ya custm2500, just saying plenty of G80's are in the grave yard with much less than a 125shot. As far as the axle technicality, sorry, you're right, it's all part of the axle system. I was just using commonology (just made that up, copyright is mine on that word) when discussing the rear end.

 

I have juice on my truck and only used it at the track so far. 10 times or so.

We are all basicaly on the same page and it is all good. Plenty of people upgrade to atleast a stock 80E or better yet a built one.

 

In my case i wouldn't be using it on the street very often or even at all. I go to the sand dunes and race 300ft. sand drags or mud drags so its not like im gonna be running down an asphalt drag strip. I just want something thats gonna give me a lil bit of an edge over some of my buddies trucks

 

is this true about spraying b4 the maf that it will correct it self?
