tell me what you guys think what do you think a 5.7 hemi can handle saftly
75,100,125,150

and maybe different mods in the mix intake, headers, exhaust, gs esp mod, wet or dry what do you think is better

i am going to bump mine up to 100shot and get gs esp mod as well let me know what you think

i think if these cars are handeling the boost all the time why not the nitrous just once in a while please give me your input

i dont know how you guys use your nitrous those who have it i have never sprayed my 300 off the line just in second gear to scared to brake the rear end or something along that line but let me know what you guys think it will handle

if you have time to read this thread you have time to write back i have answered alot of questions about nitrous and the last few knowone answers me back

i sprayed the living crap put of my 03 hemi truck biggest shot i ran was a 175hp shot on the streets destroying a lightning, at the track i ran 125 to 150hp shot i went through 38 bottles with no problems after you install your kit get to a dyno and have your a/f checked to be safe......make sure your running a good wet kit and colder plugs gapped at 35k part number # NGK4306........do not run a dry shot theres no way for the computer to adjust for the nitrous......my 03 hemi truck weighed 5000 pounds it was a loaded longbed and ran 12.4s in the 1/4 mile .......these motors are alot stronger then some might think ......get the tune right and you will be fine......with a 175hp shot my truck put down over 500hp and 639 tq to the wheels on a dyno.....with the drivetrain loss on a truck at 23 to 25% that = over 600hp and 800tq at the motor this was a stock motor that has never been opened

theres alot of tricks and secrets using nitrous if you need any info give me a email

i have a zex kit it adjust the air fuel by itself with one step colder ngk irdium plugs works great just debating on if i should try 125 but deffinately 100 shot will probably dyno in mar or april weather sucks up here , but good news i am having the tranny leak fixed and the gave me a magnum to drive until mine is fixed i like that magnum too

you should never run irdium plugs with nitrous......whats the gap set at???? make sure you get your a/f checked before you run a 100 shot of juice

 

[hemi777]

the spark plugs worked fine so far but what do you guys suggest and why arent they any good

for a small shot they might be fine but on a 100hp shot or bigger there' s a very good chance for a big problem........the plugs that you want to run are NGK 4306 make sure you gap them at 35k .........i have been tunning and racing these hemi motors for almost 3 years and never have had a problem and i run all my toys very hard .......make sure you have the right plugs and have your a/f checked on a dyno........

 

[hemi777]

it says that part number does not exist and is that one step colder thanks for your help

heres a link for the 4306 plugs.......they are one step colder then stock

[hemi777]

it doesnt say anything about fitting in a 5.7 hemi just the v6 but i hope you are right i just ordered 16

i'm 100% sure the right plugs to get for nitrous on the 5.7 hemi motor is NGK 4306 ......make sure you gap them at 35k......i can post several links to hemi guys running these plugs with nitrous.......
