Ok Here's one that i havent seen on this thread. Whos Using Lafing gas and on what type of FC

1. S4 NA
2. S4 TII
3. S5 NA
4. S5 TII

Also please state how often you hit it, how much of an HP increase, and and how many miles your engine has on it.

Thanks

Thread cleaned up. Funny how that resulted in every reply being deleted. Happens again and the thread's gone.

haha, i missed this one

Where is Scathcart? That man probably has NOS on his lawn mower...

6 people on this entire forum are running Nitro???

^ that sounds about right. I wish there was more of it in use, as it seems like a really fun way to give your car a kick... but nitrous injection doesn't have a very good rap around this forum.

I was thinking about some way to link a system with the 3800 RPM auxilary port system on th N/As. that way, you wouldn't have to worry about flooring the gas pedal and activating nitrous at low RPM. instead, there would be three criteria to achieve before the spray would spray: 1) system armed 2) pedal floored and microswitch touched 3) engine speed above 3800 RPM

if I could ever afford to safely do nitrous in my N/A, that's what I'd do

sorrry....wrong thread...this is an edit

I think once this motors is together and the rest of the car is straightened out, the next mod I'm saving up for is some nitrous. Its all about the numbers.

dude, check out: 1300cc.com

ull find a write up called: "NOS on a Rotary: Everything You Need to Know By: Sean Cathcart"

the guy uses this stuff to brush his teeth he's so informed about it.

i highly recommend it.

It's called an RPM activated window switch, in my last car I used it with my Nitrous system so it would only be on between 4k and 7k. No worries about fuel cutoff.

Roy James

How much for such a window switch? I don't see exactly whats wrong with a toggle switch, and a momentary switch in series, although I've never had a nitrous system installed on any car I've owned. Just seems cheapest easiest on lower shots (say under 100 obviously single stage). Just my two.

rxcyprus7

a window switch would be ideal...

ckyguy

couldn't you just flip the arming switch after flooring it to the rpm range you want and that would act like a 'window switch' until you flipped it back or let off the gas?

scathcart

*Raises hand*
Sup guys?
I won't vote on the poll, but I have done installs to all of those cars.

For arming of the nitrous system on an N/A:
-You can use a window switch, which makes things a bit safer and more idiot proof, but its really only required if you have a tendency to bounce off the rev limiter, which is fatal under nitroud injection. If you can keep it off the limiter, you're fine.
-The auxilary ports MUST be open when you engage the nitrous system, otherwise you get deadly nitrous backfire, no matter if you're using wet or dry. To ensure this, you can do a couple things:
- Wire the ports open all the time.
- Use said window switch between 4000-shift point
- Wire your port actuators to open whenever the system is armed. This is what I do. I use my own method of electronic auxilary ports, and then just wire them to receive voltage whenever the master siwtch is flipped.

Anyone want a wiring diagram for your typical N/A nitrous install?

I'm in the middle of installing a kit on my t2 at the moment. scathcart - as i understand it the nitrous will increase the boost so this is my plan. i've been running 10 psi on the stock turbo for a while now with no problems, the only fuel mods i have are a walbro, fcd, and safc. i am going to disconnect the mbc and run the wastegate at stock opening pressure (5 psi i think) to see what the boost creeps to. I figure that if it does start to creep to far this will give me time to get of the throttle. once i see how far it creeps i can then turn the boost back up to a safe level. Do you think this method will be o.k ? Its an s5 btw and the wastegate is not ported, i also have a cone type intake and am waiting for a 2.5" downpipe and midpipe to be delivered. the lowest jets i have are for a 35 shot so i plan to start with them.

scathcart

As a very minimum, port the wastegate. Nitrous is HUGE on exhaust products.

rxcyprus7

a wiring diagram would be great Scathcart. Also have you ever put the activation swich up on the steering wheel like a push button type switch? It's give more control

RarestRX

Yo,

There's the man!

Heya, I've got a question for ya. Do have any experience with the NOSzle product:

http://www.holley.com/HiOctn/ProdLin...NS/NOSzle.html

Looks like you just plug them in where your primary and secondary injectors are. Looks simple, no tapping manifolds, just plug and play.

If anyone has used 'em, it'd be you. *grin*

Thanks!

scathcart

I have used them on a different car... 4.6L mustang using the existing kit.
One thing I was unsure of with installing them onto an FC is getting them to clear the intake manifolds. The NOSzles space the rack up a significant amount, which could cause clearance problems making the stock primary rail hit the intake manifolds (on N/A's).

Overall, though, I wasn't that pleased with the product. It seemed a lot like a Ricer hype product than one designed with performance most in mind.

Keep in mind with nitrous you want its injection to be as far as possible from the intake ports for the best atomization; something that does not exist with the stock injector locations.

scathcart

I have done installs using a push-button mounted on the steering wheel... I hated it.
I suppose for drag only use it would be fine... but I'm not a drag only guy (which some argues doesn;t make mush sense for nitrous use). The problem lies when you want to take a corner... which becomes impossible if you are holding down a button on the steering wheel.

I simply install a toggle switch in the center console, and then flip that up when I want it (which has been during launches )

rxcyprus7

thanks for the input... Do you have another switch on the console that injects nos into your car while your hittin it goin around corners? ()

gsracer

I'm one of those people. Where in the world would you use nitrous outside of drag racing. It's illegal to use in scca solo II competitions. I'm not sure about solo I, or other circuits like NASA but I'm sure they don't allow it either.

4SPresident

So what kind of times are people running out of lightly modded S4 NAs with N20?

ConVert

Nos is illegal in Iowa. But the goddamned cops get to use it, good thing there's a "no chase law" in city limits, :p

scathcart

Driving a car isn't solely about competition.
I've used it for street driving and at casual track events to pass some of the higher-dollar cars.
