Is there anyone that is spraying nitrous along with forced induction? I'm planning to run a 75 wet shot along with 15 psi of boost but dont have much info about this setup. I know how to tune for nitrous but dont know about the possible results. anyone that has experience in this setup?

 

FI + Nitrous = BOOM

Why not just up the boost?

 

He's got a built motor and nitrous can be a very good addition to a boosted vehicle if done RIGHT.

Two reasons. Compressing air further produces more heat and nitrous cools the intake charge significantly. Heat wise, we would be better off with 5lbs of boost and a 100shot on top of it to make ~450whp than with 9-11lbs of boost. Much less heat and therefore more efficient power production and a lowered risk of detonation.

The offset of all of this is that nitrous refills aren't cheap, and if you drive your car hard a lot and want the power all the time, this definitely wouldn't be the way to go. More things to malfunction and more things to monitor.

 

Yeah, I was being a bit facetious with that response due to the post title, but I'm aware of the properties of n2o, thank you.

The last I heard, the UTEC was able to control nitrous injection applications but I have yet to hear any feedback on it. Besides, it appears he's already running water/meth so he is already taking advantage of a method of cooling intake charge temps.

I'm not sure whether we're talking about running both simultaneously? hmm...

 

If you are aware of the properties of n2o then you shouldn't post "Why not just up the boost?"

ok

Both boost and nitrous simultaneously?
or
Both nitrous and wather/meth simultaneously?

 

Yes, I have a 100 shot hooked up through the spare solenoid on UTEC. UTEC essentially allows you to control the "conditions" that must be met to spray.

Conditions such as RPM, throttle position, intake air temp, coolant temp and manifold absolute pressure.

I really only use RPM and throttle position.

 

The comment on upping the boost only applies if the compressor is being forced to pressurize the air beyond its efficiency. The increase in pressure of 5 PSI if maintained in the same efficiency band should have negligable affects on increasing compressor outlet temps. With a good intercooling strategy the change should be minimal in terms of increased air temps at the throttle body. That being said I would prefer to "up the boost" with water/meth injection added as opposed to nitrous. If anything I would say if you plan to run MONSTER snails then sure a small 35-50 shot earlier in the power band will get you moving and get your EGTs up to spool the turbos but once they reach boost threshold I would kill the shot...

 

with my current setup i dont need NOS to spool my turbos as I'm using the stock APS turbos. Of course i can ramp up the boost which is one of the things that I'll do as soon as I upgrade my fuel setup to twin pump and 1000cc injectors. I'm planning to use nitrous for emergency situations only

Isn't that the vid of the guy who attempted a 300 shot on a Z?

If this is true (300 shot), that's his stupidity.

 

that looks irrevelant, he's holding a stock rod and has a smile on his face.

 

Hello and welcome to 3 years ago.

 

i know its old...but it never gets old...i love that video...
