Fast?!?! Nitrous?! Haha

So, anyone played around with nitrous? Particularly svt's or zetecs? I've tried to do a bit of research, not much helpful info. What's your opinion? What else should be changed? Is it safe? Worth it? I'm just wanting a little extra ooomph every now and then. For the most part the Svt can... (street racing is illegal and highly not recommended), let's say "handle" si civics and such, but occasionally a v8 truck needs to be put in it's place. Cough cough. Haha. Anyway, but for real, all jokes a side, it's a daily car. So just opinions and info, like where to get nitrous filled? How long can you keep one fill?

Not even worth it... Your more likely to blow somthing sooner than later i would honestly go with Forced induction than nitrous lot more safer on the car especially if its a DD if you have time and money and want to got that way i would rebuild a junkyard motor with forged internals then it should be decently alright to run nitro. I just dont like it do to the fact your motor life diminishes very quickly

I think a 50 shot with a good tune would be perfect and safe!!

i used to run a 20 shot with a venom nitrous kit no tune, stock besides some basic bolt on's... never any problems... quite fun really...but IMHO boost is a whole nother level.. of course with a pretty price tag...but worth every penny... i dont even have my nitrous hooked up anymore.. its there but empty tank. besides i dont wana blow up my internals just yet.. (stock) lol

IMO, nitrous is kind of a waste.

First, its alot more dangerous than going FI, and if you go with a small enough shot that its not so dangerous, the resulting output isnt very great.

Second, its costly, the kit itself may not seem to expensive, but refilling that tank all the time will start to weigh on your wallet if you are pressing that button alot.

Third, it just cant stand up to proper FI. A decent supercharger or turbo will smoke you all day because they arent limited by how big their tank is. (well.. a supercharger can over heat fairly easily.)

Buy Cody's supercharger, you will love it, i do.

Nitrous is just as dangerous as any other power adder. I've run dozens of tanks through my Mustang and it's had no ill effects whatsoever.

Running any dry kit on a fuel injected vehicle is a generally bad idea because you are literally hoping that your open loop fuel enrichment will adequately cool the cylinders. Nitrous it's just an oxidizer....and gas engines require a certain ratio of air/fuel. So...if you add more "air" you have to add more fuel or bad things will happen.

Using nitrous safely typically requires the use of a wide open switch, a fuel pressure cutout and a window switch. I usually spray a 100 shot which is established by fuel and nitrous jets that are replaceable within my throttle plate spacer. I also use a gauge and a bottle heater to keep my nitrous pressure as consistent as possible because this will affect the desired gain.

With the bottle open, the activation switch closed, my throttle under WOT, fuel pressure greater than 40psi and the window switch only activating the nitrous between 3000 and 6000rpms I am almost guaranteed never to hit the rev limiter, burn too lean or overload the motor at too low RPM.

The only real danger in using nitrous is having a full tank of unknown condition cooking in the sun, having the incorrect fuel jets installed, losing fuel pressure or hitting the rev limiter. Sounds like a lot but considering I have control of when the nitrous does and doesn't work I don't think it's incomparable to a blower.

The blower is a few thousand $. It will require a lot of labor. It will require a tune and the power is there at all times.

I honestly like the fact that I can control when my power adder is active. It makes grunge matches more fun to negotiate, I feel safe giving the keys to friends who aren't perhaps the best drivers, and if I'm not spraying it I have no worries whatsoever about collateral damage like crank walk, belt slippage, detonation, fuel consumption, etc.

That being said my opinions on spraying a car like the SVT focus are even harder for others to swallow. It's a joke. Why spend all that time and $, risk all the damage for a car that isn't going to run times fast enough to impress anyone. Maybe I'm just old but my high 12 second car isn't what I would consider fast. Plus... I've got like 6 grand into the whole thing. Not only is it a "joke" to eek out 15 second 1320's but you are certainly not getting much bang for the buck.


The best advice: Keep your car nice, clean and stock. Drive it with respect. These are nice daily drivers that are fun to drive. If you want a toy that makes your heart beat and palms sweat - buy something older with RWD and more than 4 cylinders. You'll have more fun in a 20 year old bolt on foxbody than you ever would in a focus with nitrous/supercharger


...IMO of course

Some real wisdom to this.

But ill put in my 2 cents on top.

Foxbodies are to the dragstrip as Foci are to the twisties. To each his own, but when I mod my car, its for the twisties, and its pretty clear that NOS is not intended for those.

Just because the focus isnt a god at the dragstrip doesnt mean that you will get any less pleasure out of boost, it just means that you are going to find that pleasure on a different patch of pavement.

^I agree. If I had a drag car I would probably have a sick na motor with some N2o on top. N2o is used at WOT anyway. Perfect for the strip. In the Focus, I'm looking for handling. Hitting the twisties is fun. It's ALOT more fun with some boost.
