How effective is Nitrous?

Just came back for some street racing, i ran the 98, My friend ran his 99 Dodge, its got a 66 Turbo, ?injectors, Edge comp, studs and rings. 080 shot NOS

I Beat him by about a truck length, fuel only.
When he would spray, he would beat me by about 2 or 3 truck lenghts...

Id say in total 4 truck lenghts, and thats with some lean mexican nitrous

How much would it drop ET's spraying on my truck?
i believe id have to get studs too...

What difference does it make on ya'll trucks?

You must have the extra fuel to go with the nitrous.

You can only spray enough NX to clean up the extra fuel you have

according to NX nitrous in a diesel is nothing like it is in a gas motor. They say you can throw average of a 150 shot before diesels have problems

I took my 01 24v from 550hp #2 to 790hp on Spray and from a 12.36 to a 11.48 at the track with quite a few dyno runs to tune it that way. So it can make a pretty big improvment but you'll need studs and o rings too prob..

Nitrous is an OXIDIZER. Think of it as an extra turbo pushing more air not as more fuel. You need fuel for it to be beneficial.

i was figuring i'd need more fuel, it doesnt smoke much now at WOT...
I'd like some Mach 4's (waiting on a good deal on a used set)
But im wondering if they would be too small, if i wanna use nitrous??

dzlfarmboy, what size injectors where you running? thats almost a full second which is great!!

How do you tune nitrous on a diesel? I know on a gas engine you will change your timing and check you A/F so you aren't lean.

Just trying to learn.

I have a progressive controller that I can change the ramp, amount and there's different jet sizes to try, along with changing your fueling aswell.

I just noticed that yours is a 12V so that will change things a bit also.
