hey whats up peoples, i've read and heard alot about nitrous kits but i still have a few questions that i'd like answered directly

- first of all, i wanna get at least a 75 shot but would love to get a 100 shot or more, what should you have done to your motor and what not to reinforce it so that it can put up with the extra abuse of a nitrous shot that big every now and then? cause i think i'm going the bottle route with a few bolt ons until i can afford a bigger motor swap and H/C/I for it, and i dont wanna trash my motor till then cause it could take a couple of years for me to save up

- second, can some one please explain in simple terms (possibly one sentence[&:]) the difference between a dry and wet nitrous kit

thanks alot

 

well first off, u can put a 100 shot on a stock motor, the only thing ud have to do is retard ur timing 2 degrees. ud be fine running at the track all day with a smaller shot on a stock motor though. the difference between a wet and dry kit is simple. the wet kit introduces a no2 and a fuel mixture into ur motor at the same time and a dry kit is strate up no2. dry kits are a lot easier to install and are a little safer on a stock motor

 

ok cool so if i got a 100 shot and retarded the timing 2 degrees, then using it every once and a while wouldnt hurt the motor?

 

Not completely true,
You're also going to have to up the fuel to make it so it doesnt run lean on ya
And, you may want to run a step colder on your plugs too, just so they last...

 

how would you do both those things? [&:]

but yeah if i did all that then the 100 shot wouldnt tear my engine up?

 

A wet kit is actually safer because: when you introduce nitros into your combustion chambers, you need extra fuel to supplement it. A dry kit depends on the computer to sense this and compensate. A wet kit either taps into the existing fuel line and adds the extra fuel, or it has a dedicated fuel pump and a seperate fuel line to compensate for the extra fuel needed. The 2nd is actually safer, but either way, a wet kit is safer.

 

The plugs just need a more narrow gap.

 

Not true on the 5.0(if he's injecting before the TB)

Fuel is NOT supposed to travel thru the intake, and with the extremely odd shape of the 302's manifold
It pools, and will eventually A-Splode.

 

True, that applies on all EFI (dry manifold) cars. But I.m talking about 4.6l or on big shots that the computer can't compensate for on stock fuel pump and enjectors. The 4.6 is a dry manifold car, but has a returnless furl system, unlike the 5.0's

 

ok thanks alot guys, so this is what i have come up with:

for a 100 shot of nitro --

- advance your timing 2 degrees

- get plugs with a more narrow gap (or can u adjust it?)

- increase your fuel ratio in the mixture

ok so i still have two questions then [&:]

1. can u adjust your sparkplugs to run a narrower gap and "run colder" or do you have to buy some narrow gap plugs?

2. what would be the best way to inrease the amount of fuel to compensate for the nitrous?

thank you so much OB and GT00
