Nitrous oxide and the M30: deadly or doable?

[Rustam]

the problem is good distribution through the manifold, most cheep nos systems are designed for "wet mainfolds" where they are designed to flow fuel and air evenly to all cylinders and a little more fuel and air (nos = oxidizer) from a single injector works good, the bmw uses a "dry manifold" that wasn't designed to deliver a fuel charge, imho the safest system would be one with a fuel/nos nozzle in every port just like the factory injectors, but that style of system is not cheep, easy to install or for small power increases, now people have run cheepo nos on 535s for years and i suppose a few melted pistons have resulted from pushing the limmits over the years, you just need to research what the safe limmit is for a cheep system and realize it's a dice roll

why bother installing a nozzle into every port if one can simply put one before the throttle plate?

[Rustam]

Not yet. I ordered some new bolts for the oil spray bar. As soon as they arrive I'll tackle the job.

Thanks for the input guys. It sounds like a modest NOS shot might be doable, but I'll leave it for at least a few more months.

don't forget the price of refilling that NOS tank

good distribution so that one or more cylinders doesn't go lean and melt, the bmw intake wasn't designed with fuel flowing through it in mind, and you can't add a oxidizer without something to burn so you need fuel too, a single nozzle spraying into the throttle body is not efficiant with all of that complex manifold piping for the mixture to condence on the walls of and dribble into the ports, yes it can make some power much over 40-50 and you are seriously asking for detenation, the $400-500 spent on a nos system (plus what you spend on filling the bottle) could be better put to use on regular mods that are with you all of the time and are less abt to malfunction and hammer your motor

Not to bring up a dead thread, but i was curious on the subject of nitrous and i have to ask, what about using a water/alky injection in conjunction with nitrous??

I know the water inject kits help to prevent knocking/pinging and alot of people use them on turbo applications so they can run more boost.

So basically running NOS thru the factory intake system, whether it be the intake itself or the intake manifold will not work because, BMW did not design the intake system to have fuel running through it.

I have an m20 and wondered how a small hint of NOS would work well when in need of more power. But after thinking about it, I cannot figure out where I would install the fogger besides directly into the cylinders. Is there any other way to run an effecient NOS system?

This is the part I don't understand (okay, I don't understand lots of things...).

NOS is a gas. So is the air in the atmosphere. So how does NOS cause problems in the intake? It's just adding oxygen, after all, not liquid fuel.

[Bimmer Nut Ed]

Don't forget, Gas is gas too. It all depends on what pressure they are under, and what temperature they are at (eg, liquid nitrogen).

have you seen the top gear where they drive that nitroused jag off an air-craft carrier

[BillionPa]

i would think that installing a fogger inside the top of the air box would have the best distribution of NOS for the incoming air charge, assuming you dont have a turbo or supercharger. although i have no idea how that would effect the MAF... at WOT is it even used?
