Anybody using NOS on their scoobs or had any experiences of using it?

Am considering it for the occasional drag event but need advice as to the effectivness and the type of system to go for.

Thanks in advance.

In france , a serious runner M Violet) use it on his impreza turbo my98 and he has broke 3 blocks. You need to install strengtened parts before install Nos into your car.

There are guys on here running upto 400bhp on stock UK internals (not using NOS).

NOS is occasional use so surely less chance of damage than getting a bigger turbo etc and keeping std internals??

Surely 270bhp with a 50BHP shot of NOS is less destructive than a constant 320BHP??

I'm not quite so sure I'd agree with this statement. I believe the extra strain on engine through 50bhp of NOS and 50bhp of extra boost etc is not going to be very different.

I think the reason you see NOS mainly on NA vehicles only is because on a turbo charged car you can wind the boost up a bit and have the same results, but at less cost.

I see from another thread that you are thinking of fitting this more of a costing issue. You need to be aware that it is not going to just cost you the equipment for injecting the NOS, the ECU will need to be remapped to allow for this too, as it will have to add more fuel whilst the NOS is running. I cannot remember what mods you are running, but surely a manual boost controller would be a far cheaper and safer solution to implement.

I have got a stock TD04 which is set at 17.4/17.5psi (via tek3). Cant imagine that cranking it up anymore would be a benefit.

Also I would only use NOS on the occasional event (lets say 5 days of the year)...compare this to having 320BHP 365 days of the year straining the engine and wearing it out...

therefore in my opinion the NOS method would have a less adverse effect on the engine.?

Personally I'd think the temperatures caused by using NOS would be way above those generated by using a boost controller.

Correct me if I'm wrong but I'm sure the temp of burning NOS is way hotter than burning fuel alone, and therefore would probably melt something internal much quicker.

I thought the temps would be lower using NOS?

will check.

NOS is a very much understood with many myths that 'it will blow your motor'.

I'm not sure if I'm right but a td04 can only manage about 270 bhp tops so if you stuck another 50bhp across it wont it go bang. Surely a bigger turbo would be needed to take the strain.

But I dont really know what I'm on about.

Any experts around these here parts???

===WRX===

dont you mean Nitrious Oxide?

NOS is a manufacturer...lol

I have a friend who runs it on his WRX...good results with a 50 shot, but i am lead to belive that Nitrious has other traits other than a quick bhp fix, it also has a habbit of finding weaknessing in the engine and "opening" them so to speak, where as a boost increase is a little less prone to popping things..in moderation of course....

any-who...his works fine, but a good saturday night session with the saxo queers will see you £35 lighter and a trip to BOC for a top up of N02..

not my cup of tea...but you never know


all the best

Nick:

Doh!...didn't consider that.

Will have to look into it...I was just looking at the limitations of the engine itself.

WRX:

I don't intend to use it on the road as I have not come across anything that requires me to put out more power than I currently do...certainly not saxos.

Will be for drags only.

Yes it is nitrous but its easier to type NOS and I'm sure that everyone understands what it means.

What mods your mate with the WRX have?

===WRX===

Hello Sir...so far ive got

Apexi PowerFC
Apexi AVC-R
Apexi Turbo Timer
HKS SSQV
HKS Super Metal Flow Induction
HKS Plugs
HKS Down Pipe
HKS De-Cat
HKS Hyper Back Box
Bosch Coil packs
FSE Ajustable Fuel Regulator
280lt Evo Fuel Pump

Full Cusco brase Setup
Ap organic Clutch
18" Super L's
Toyo S1's
Geometry setup ( had that done yesterday, best cash ive ever spent )


its a tidy setup, lots of power and lots of tourque, i have a bottle of Nitrious myself, but ive never plummed it in as yet, just found out my turbo needs a overhaul so it looks like its bottom of the list again..lmao


cheers

all the best

oppsie..you ment him....lol

not much to be honest, decat, Backbox, FSE, Apexi Induction kit..not much but its intresting to say the least, he uses it for a sort of anti lag senerio if you get my drift...

also with nitrous if you run anything bigger than a 25bhp jet you will need to retard the timing too!

Just been doing some research...


N2O actually reduced the charge temps by a fair bit

Only need to retard timing if going for 75bhp jets or greater.
