I've decided to go the nitrous route with my 02 denali as I need too much money for school to afford a blower. I've been lurking around the nitrous forums and am tossed between an hsw kit or just drop the money on a nice package from nitrous outlet. How much can I spray on an lq4 denali without issue daily? I figure an FLT trans is inevitable but will a 100shot be acceptable without issue for now? I plan to buy heads, cam and fueling later but just wanted some opinions on which kit, how much to spray, and what other parts are a good idea.

 

I just got my HSW kit installed and love it. just get a window switch set it up to fire @ 3000rpm and to cut off right before you shift and you'll be fine with a 100 shot. some people say these motors can handle up to a 150 shot but i like to play it kinda safe

 

here is a fool proof list of parts i bought if you want your setup to be as reliable as possible:
-HSW Sudden Impact Single Nozzle Wet Nitrous Kit
-HSW Revolution Nitrous Bottle Heater Kit
-Nitrous Purge Kit
-BMN Window Activation Switch
-Fuel Pressure Safety Switch
-NGK TR6 Spark Plug

 

Damn how is your tune on/off bottle? I'm getting a tune ordered up but I almost wanna wait until I install some dynatechs. You track it yet with the nitrous?

 

i dropped the truck off with my tuner to let them put it on the dyno and have at it. im pretty shure they just pulled my timing to stock and made sure i wasnt going lean or anything. as you can see i trust these guys LOL!

 

NX 150 wet shot on my 5.3L, no problems

Switched to TR6 plugs, and pulled timing via EFI Live COS5.

 

I spray a 150 wet shot through a 135,000 mile 4.8L, I do have a 255L/hr pump tho...

IMO stick with a 100 to 125 shot with the stock pump and have fun...

 

+1 i spray a 100 shot regularly and sumtimes a 125 without any problem.

 

Sounds like I'm buying a fuel pump and an hsw plate kit, hopefully I can click off some mid 14's with 150 shot up here at altitude otherwise I'm taking out extra loan money for a blower.

 

do you have a yukon or a sierra denali. if its a sierra then 14's is gonna be easy, maybe even 13's, but if its a yukon, then its like my tahoe, big and heavy and 14's will happen on a 150 shot, but your tranny will probably suffer lugging all that weight.
