Better off fitting a more powerful engine TBH.
Nitrous is only rented horsepower.

[billgatese30]

Nitrous is only rented horsepower.

meaning what exactly?

[N00b]

Nitrous is only rented horsepower.

meaning what exactly?

Meaning when your bottle is empty your bhp gains vanish. Nitrous has it's place, but on a 316 isn't one of them.

[gareth]

next time you're in the supermarket, have look at a can of whipped cream...
the propellant is nitrous oxide!

cream injected 316i anyone

[DRIFTBOY]

Nitrous has it's place, but on a 316 isn't one of them.

Why not?

[N00b]

Nitrous has it's place, but on a 316 isn't one of them.

Why not?

Because for the cost of a nitrous system you could fit a more powerful engine.....and one that will have that power permanently, not as long as the bottle isn't empty.

Why would you add Nitrous to a 316?

[Gunni]

Cause you want 316 mileage and 200hp´s when you want.

[N00b]

Cause you want 316 mileage and 200hp´s when you want.

I assume you mean 316 economy and 200bhp available?
Will the 316 produce 200bhp with nitrous only?

lol have not got the time for engine swops unless someone would like to do it for me i just wan the power when i feel, can someone point me in the right direction

when your petrol tank is empty you loose all your power completely...but we keep it topped up to prevent that, as you would with a nitrous bottle

The day a bottle of Nitrous lasts as long as a tank of petrol, I'll agree with you, or when there are as many places to top up a bottle as there are fuel stations.
A bit of a hollow argument though as an engine will give all of it's power as long as it has fuel, whereas Nitrous Only gives you a boost in extremely short bursts. Plus it can be extremely difficult to know how much Nitrous you have left in your bottle depending on the system, whereas remaining fuel is much easier to assess because it's used at a slower rate.


Why don't F1 use Nitrous, for example.....or rally cars?

You're either going to fit a nitrous system yourself, or pay someone to do it for you.
In either scenario, an engine swap is almost certainly going to be cheaper and take just as long to do.

[Rav335uk]

Problem with doing an engine swap on a 316 is that all the suspension set up will have to be uprated too.

[N00b]

Problem with doing an engine swap on a 316 is that all the suspension set up will have to be uprated too.

If you add Nitrous (and as a consequence an extra, say, 50bhp), wouldn't you want to uprate the brakes and suspension anyway?

was going to do this anyway, also i could fit the nos no probs, but the engine is a different thing, i have no crane or anything so...

Bigger engine, more weight, NOS, no extra weight really.

[gareth]

you'll add 10 or 20kg or so with nitrous i reckon, by the time you've considered the bottle etc.

err, the rules would probably be the main reason!

[billgatese30]

a lot of the setups that i have seen on race cars use a thermostatically controlled jacket to maintain a steady bottle pressure so that a consistent amount of gas is delivered.

this is also partly the reason that people melt pistons from running lean and say nitrous is too much of a black art/game of chance, what a crock of shit, you just need to remember its a compressed gas and the amount delivered to the intake is dependent on its temperature and thus the pressure it is stored under and not to get too greedy that they can't supply a sufficient amount of extra fuel to stop it going lean. assuming you can get those right, you need to make sure your exhaust valves can flow the extra exhaust gases created (heavily nitrous dependent engines often have exhaust valves increased to as big as or larger than the inlet valve)

I know people who have ran race engines for over 15 years and never melted/damaged anything from running lean due to a high bottle pressure (or at least higher than when they set their mixture to be an ideal AFR)

This is because they know what pressure the bottle should be at and control it to be as such (as with the bottle heater blankets) as the hotter you get the bottle, the higher the pressure as the gas decreases in density, thus raises in pressure.


you can see when a bottle gets low on gas as it either struggles to get to temp, or is at a low pressure for the ambient temperature (my brother ran it on his old race car and in normal ~20 deg C temps it should never dip below about 800-900 psi before we put the heater on, we aimed for 1100-1200 psi to do a run, when we struggled to get it to 1000 psi we knew it needed a fill)

As I said, Nitrous does have it's place. I just think that on something like a 316 the same outlay would be better spent swapping to a more powerful engine.

An engine hoist is cheap to hire and easily available. If you're confident enough to install a Nitrous system then an engine swap will present no problems (unless it's something radical of course).

[Chuntington101]

N2O isn't always cheap power! It can get very exspensive very quickly! lets sya you start off with a simple setup spraying 50bhp through a wet system... then you want 75bhp.. then you need a timing retarding box so you dont blow the engine... then you want 100bhp... thenyou have to forge the internals so you dont melt pistons...then you want a progresive controller....then you want a second 50bhp stage on there.... then you want a sand-a-lone fuel supply so you can run more N2O...then you want a 2 stage system with 100bhp hit followed by a second 100bhp hit but on a progressive controller... beofre you know it you have as much money in the N2O as you do a Turbo setup!

not having a go at N2O, i think its great when used right.

Also has anyone seen the pusher systems???? they use N2 gas to maintain the N2O presure rather than heating the bottle. It means with say a 10lb bottle you can use all the 10lbs of N2O rather than only getting 5 or so Lbs.

Cheers

No point in a progressive contorller unless you are using it in track day's/races as you would want it on all the time when on full throttle. I use it just for sprint's which needs quick direct burts of full flow.

On a 316 you can only run 40hp with out causing damage, and to honest 40 hp is not worth doing as you won't notice it. If you run 100 jet in it you will need to replace your engine very quickly. So as above fit a bigger engine.....

[Rav335uk]

Put an M30 in it and NOS that fooker, 400 bhp no probs

[Barx325i]

you'll add 10 or 20kg or so with nitrous i reckon, by the time you've considered the bottle etc.

Why don't F1 use Nitrous, for example.....or rally cars?

err, the rules would probably be the main reason!

an f1 engine has more than enough to deal with without adding the compication of excess cumbustive energy, it's like giving the worlds fastest sprinter a vile of amphetamine, he'd just melt!

[zaust]

Put an M30 in it and NOS that fooker, 400 bhp no probs

No more than 100 extra on an m30 or bang fella, So with the right bit's thats 340 ish

Not really, as dragsters run nitrous and they generate far more internal heat.....and they measure bhp in the thousands. F1 doesn't use it because it's a power gain that just doesn't last any meaningful amount of time at all.

I thought these things could take upto 400bhp no probs??

[zaust]

Not nitrous mate, you could run up to 400 with FI

[Barx325i]

but they run on nitro fuel, they don't have N02 button. a drag engine is built with tollerances designed for 10 seconds of huge power from supercharged high capacity whereas an F1 engine is a discustingly highly tuned & delicate motor which needs to last a few races.

A drag engine can't be compared to an F1 engine sorry

in fact, an F1 engine is probably so efficient at combustion & the power it creates so close to the limits of its strength it'd just go bang with nitrous.

I'd like to see it.

[cypriot_boy_2k7]

way off subject

[UweM3]

way off subject

but still a stupid idea IMHO. The time and money it will take you to get it running right you will fit another engine or even buy another car with a bigger engine.

[cypriot_boy_2k7]

not getting another car, how long would it take to plum in?

[N00b]

but they run on nitro fuel, they don't have N02 button..

Yes they do.
Top fuel dragsters use Nitrous Oxide. Fact.

i'd be interested to see how what your definition of "discustingly highly tuned & delicate" is TBH. A top fuel drag engine produces more power per litre than an F1 lump, generates more internal heat, tends to run at a higher CR and needs a rebuild every 5 seconds or 500 yards. SO by definition, the drag motor is in a higher state of tune and far more delicate.....it almost makes an F1 engine look like one from a daily driver in that respect.

Anyway as mentioned this is getting WAYYY off topic, so back to the OP.
Fit a bigger engine. Even if Nitrous gives you the initial rush you're after you will soon be wanting more. Fitting a more powerful engine will be a much better starting point for you.
