hi guys..

anyone had nos fitted to their scoob?

if so, was their any problems and how big of a shot can you add without blowing things up all the time?

cheers,

dan.

 

im enquiring about nos too.

any info would be good.im looking at this shop.

NOS fitted blindly with no other mods can lead to problems.

I've seen blocks with holes in them due to dodgy NOS installs.

You'll need to make sure that your fuelling system is up to the job of providing the fuel necessary to stop the car from leaning out. You'll also need some way of retarding the ignition when the nitrous is used. So you'll need to alter the management.

You would also be wise to fit safety devices such as a knocklink and AFR gauge to keep an eye on things and make sure you aren't about to meltdown.

Personally, I think there are far better and safer ways of extracting power form the Subaru engines. Many people on here have high power cars without the need for laughing gas.

Also there's the issue of filling the thing up every time. I would imagine if it's your daily car, the NOS will be used quite a lot (too tempting not to) which will work out expensive.

There's also a few people on here WITH Nos, so i'm sure they'll add their input too, but my humble opinion is do it another way unless you are confident that you (or who fits it) knows what they are doing.

 

look here http://www.twistedsanity.com/Index.htm ,full kits ,progressive controllers ,and they run an 8 second 200mph nitrous powered drag thing . i have one of there kits on my drag car

 

try this site i have made a few of these and also built the controller not fitted to scoob as its a daily driver but if you use controller and dont go mad? i put 150 through old volvo turbo and it was ok but too much is never enough http://www.diy-nitrous.fsnet.co.uk/nos is great and can be used in small amounts ie 15hp to get rid of turbo lag using a pressure switch you will find it on the site but if it all goes pear shaped dont blame me lol

 

thanks for info

 

''You would also be wise to fit safety devices such as a knocklink and AFR gauge to keep an eye on things and make sure you aren't about to meltdown.''

had this debate before about AFR gauges and they will not show if nitrous is running lean. plus it would be too late anyway as you're engine would have gone bang.

www.noswizard.com/bboard for any questions - really helpfull place.

 

Nitrous running lean is no problem at all. Fuel running lean is the killer.

Monitoring the AFR may be a bit late, but it does give you an indication as to how it is running. Why would AFR gauges not show if a nitrous car is running lean?. The nitrous only supplies extra oxygen for the added fuel. I would imaging the nitrogen may have an impact, but not that much.

If you want to buy a kit contact this bloke on Ebay - username is mashamoto. He is based in Newcastle I believe and supplied my mates kit for his MR2.

 

not knocking wizards of nos cos i`ve never met or dealt with them,but i race at the pod and have spoken to at least 3 people who have f***ed engines with the above ,also dont know who`s fault ,so dont shoot me down i`m just passing on info.you wont hurt your engine with to much fuel but you will with not enough while using nos.

 

what cars were they running?

ive got a 1.6 8v saxo engine in my car (90bhp) standard and with the gas im running 179.5bhp with no problems at all (apart from clutches dont like it!)

but saying that i spend alot of time testing my jet sizes to get them right, whereas some people just bolt a kit on and stuff the biggest jets they can in, race round hitting the limiter and injecting a straight 75 shot in a 1.4 at 1500rpm which is a recipe for disaster.

 

Used nitrous on just about every vehicle i've ever owned, but only ever use it for the quarter mile strip, i would'nt even consider for road use, far too expensive. If your wanting extra power for daily driving i deffo would'nt recommend nitrous.

If you do go for it though, the best advise i can give is to do lots of research before you fit it, its not so much nitrous that kills engines, its the ignorance of the fitters/drivers.

I'm pretty sure the guy mentioned earlier 'mashamoto' who sells kits, runs a scooby himself, so he could prob give ya a few pointers.

 

just a quick note nitrogen has a huge effect it boils and lowers charge temps a lot and also acts as a buffer to stop det so is good for engine life lol if you dont put enough fuel with the nos it will run lean and go bang if you put far too much fuel in you will get hydraulic lock that is like a car accident inside your engine if you are serious about nos find out as much as you can about it and pref get an old motorbike or something wou can experiment on its ok having a kit fitted by someone you know to be good but if you dont understand how it works and it all goes pear shaped you will be stuck i would allways go for nos only for the reson that a scoob is a quick car fuel consumption is not great to start with and 5sp boxes are not great so if you are running say 240 bhp everything is ok squirt 100 shot of nos now and again get 340 poss more but tune the engine to 340 it will cost a lot more and be under more strain with parts constantly beyond there limits in older cars you pay your money you take your choice

 

Blimey, all that in one breath.

I think you'll find that Nitrogen is an inert gas, and if you put that in your car, it won't go anywhere

Nitrous Oxide is what you're looking for

 

ahh huh.

helps out quite a bit, thanks everyone.

could any one explain the "knock link" and also would an uprated fuel pump be enough to make sure the car doesn't run lean?

dan

 

A KnockLink is a small device with 5 LEDs which attatches to a knock sensor mounted on the engine block.
The knock sensor is basically a microphone.
Any sound is picked up by the sensor and visually displayed on the unit, by lighting the LEDs.
The number of LEDs illuminated is dependant on the amount of noise heard.
This can give you a visual display of any detonation that may be occuring inside your engine.

IMO it is not just sufficient to fit an uprated pump. This will just ensure that "x" litres per hour can be pumped from the fuel tank.
The regulator will (try to) regulate the fuel pressure at the same level as with the standard pump.
An uprated pump and adjustable reg. would be a good mod though...It will mean that you will be able to run an increased baseline fuel pressure ( and therefore enable your standard injectors to deliver more fuel if they are already operating on or at their maximun duty cycle.
Ideally your ECU will need to be mapped to ensure the injectors can deliver the correct (increased) quantity of fuel at any given load and rpm in the stored fuel map.

cheers richard..

i think i'll be needing a chat with my bank manager!

 

what i ment is that nos is made up of 2 parts Nitrogen 1 part oxygen and was in reply to previous post life is too short to punctuate

 

i thought the whole point of a wet kit was that you had another injector along side the nos,so not needing to uprate your other injectors.if it was a dry kit i can maybe see the point or run a 5th injector but they are hard to get right.
fuel pump pressure is important to get right though .
