this might make for a good sticky. i have a 95 maxima 5 speed and im wondering how much nitrous i can run before i start to hurt anything? yes i know their is not a absolute set limit but what is a safe point? i know some cars will take more then other biased on factory compression ratio or what not.
so on a 4th gen VQ30DE how much spray can i run with a dry set up and how much for a wet set up and still be safe? (well at least as safe is nitrous can be.)

 

A 75 shot is completely safe.

If tuned correctly you can run a lot more than people think.

 

i ran a 75/100shot for like 2 years and my motor is still holding up strong. that was w/ the auto trans too..I'm now 5speed

 

ya i know nitrouscan be as safe as a turbo or blower set up as long as you have the fuel to go with it. i had a 100 shot on my lincoln all i had for fuel was a fuel pressure booster. so when i hit the go button it went from 40 psi to 80 psi but i also had a 255 LHP 110 PSI pump. i saw on here some one say they were running a 200 shot in their maxima but im sure he had motor work done?

so your saying that i can run a dry 75 shot and be fine right? (of corse not holding you responsible for anything)

 

Did you have a darker colored mid 90's Mark7 or 8 ?

 

no i had a white 94 mark 8 im not sure how far you are from tarpon springs but y i know a guy there that parts them out and he had a black 93 mark.

 

I just remember a darker colored one at OSW that was spraying and I believe running low 14's.....

 

oh ya i know that guy from the Mark VIII forums i think hes on either a 100 or a 125 shot wet. wet shot on those cars can be very bad becuase the intake is so big and so long. their have been a few guys that have gotten a freak back fire and have blown the intake manifold through the hood. thats why i had mine add fuel through the injecters by raising the fuel presure not by spratying the fuel through the intake.

 

with the 5.5gens how much can our engines hold?

 

There is no definite answer.

A 75 shot is considered safe, but with the right fuel and some experience you can run quite a bit more than that.

 

not bad

 

75shot dry after that the injectors will start to max out and 200 wet

 

75 dry on a 3.5, what about a 3.0?

I'd like to do a 50 dry shot, just a straight "nitrous in a bag" setup. No timing, no tuning, no fuel upgrades, nothing. Just running a dry shot before the MAF, assuming the MAF is like that of a GM MAF and will see the enriched oxygen and give more fuel.

Basically I need to know if the MAF is a hot wire or cold wire type setup.

 

You can spray a 75 wet shot with colder plugs on 3.0/ 3.5 all day long.

 

its a hot wire. you wont want to spray before the MAF since it will make the MAF go bad quickly

 

So on the 5.5 gen, a 75 wet shot with no other motor work (besides I/H/E) is fine as long as you have colder plugs and I take my timing down from 17 degrees to like 15 degrees? Or should it be 14 degrees?

 

^ You can run a 75shot with stock timing.. Pulling timing is just a preventative thing ya know? I ran a 100shot with stock timing, one step colder plugs and a walbro fuel pump for two years just about.. If I could of pulled timing I would have but I didn't, I just made sure I had enough fuel and my afr's were good.

 

^ 17 is two degree's advanced ^

 

i have a similar question, not to jack a thread but it would be repetitive to start a new one.

a vq35 with vq30 timing in a 4th gen, what timing will the car like with n20, what the afr usually like without any adjustment???

was thinking about a 100 shot (real whp like NX kits) wet, will i have to mess with the timing or should it be good?


as far as the VQ30, i know a guy in miam that sprayed a 100shot wet forever

 

I sprayed a 100shot forever.. If you have the fuel to do it (fuel pump, good injectors, and something to tune with and your afr's are good then you shouldn't have any problems.

 

you can spray 75shot all day in a 4.5gen, to spray a 100shot I would upgrade the fuel pump

stock ecu timing is fine

 

I've been spraying a NX 150 shot for quite a while on my VE with stock timing, 2-step colder plugs, and a walbro 255. No problems yet.

 

I use nitrous before, but never on a Nissan. So all you guys saying 75 shot is safe on a bone stock factory motor on a 06 max AT? Im interested now.

 

I have a boosted Vq30. Pushing 14 psi. The tune is right on the money. Think the motor will hold a 50 wet shot? I have a greddy Ultimate for tuning

 

Only one way to find out lol.

 

Dang, yous a crazy man..your right though, if it blows vq35

 

06 6spd?

 

What?

 

basically same question, how much can my car handle..i have an 06 6spd..

 

yall crazy

 

Exactly my plan once I learn more, already have the kit. Spray should cool boost like meth I think wonder if you can run both, gotta learn and read a bunch.

 

This thread answered all my questions execpt one. What are the twice colder plugs part number or type for the 3.0 in an 01? I think a 150 shot is in my future

 

Remember to post those time slips...

 

So 75dry and 200wet? is that with stock fuel pump?

I been sprayin 75 NX Wet shot past 2 weeks no problems with 17degree timing advance and 1 step colder NGK v powers.

i understand a dry system maxis out the injectors and stuff but a wet shot really dont if i retard my timing down to 13 or bac 15 stock could i safely spray a 100 shot wet with stock pump?

 

Just read this thread man.
The answer I am giving you is from above:
With a 100 wet shot, you should upgrade your fuel pump.
You can run it on stock timing.

What are you using to tune?
Do you have a wideband?

 

Tuning with spark plugs for now,will have wideband soon.

 

 

wtf is that dude! A black video with car constantly revving?

 

I needs no gas!

 

dont understand.....but okay.
