Nitrous oxide and the M30: deadly or doable?

[Flamin'Cow]

Nitrous is like a drug, you can never have enough - and therein lies the problem. As you can only use it for short periods of time and must leave a gap of around 300 miles (or one week) between each use - it kinda defeats its own object.

Thinking back, I shoulda spent that £1000 on getting the head skimmed, perhaps a stainless manifold, even a superchip.

I hear that its possible to add the turbo from a 525 TD onto a petrol 535 engine - why not do that? - At least you'd be able to have a dump valve and make that cool 'ssssshhhhh' noise everytime you change gear.

NoS is okay if you engine is HIGHLY modified, strengthened pistons, con-rods etc etc etc etc etc. Although the BMW 'Big-Sixes' are bullet proof - I dont think NoS would do you any good.

Turbo it is

That's news to me. I didn't know you had to let so much time pass between boosts. If that's the case, I agree completely that it's pointless.

Sounds to me like you did use a "cheap zex kit"....seems kinda dumb imo because ive heard great things about zex and worse about NoS.

I see nothing about a window switch or WOT switch to prevent you from blowing your motor and doing something dumb.


Anyways im still curious. wet kit go or nogo on the M30??

Ironically - the BWW Enthusiasts guide - does an NOS install on an e28 535is. Got some decent numbers out of it.

I know the guy that article was written about, Dan Tackett. Bigtime BMW CCA guy, comes out to the autocrosses all the time in San Diego. Drifts his E46 M3 all around the course with a shiteating grin plastered on his face, great guy to hang out with, and a helluva driver.

What's this crap about 300 miles or one week between uses? That makes no sense at all... If I get into the throttle and my supercharger starts boosting, should I make sure I drive it really easy below 3000rpm for the next week??

[Flamin'Cow]

No this is only with Nitrous. Obviously you done 'have' to leave any time at all between uses - but the man from NoS says that bugger your engine up really quickly....

hes just saying that to avoid a lawsuit or something

Every time you hit that little button you take a year off the life of your stock motor... When motors are designed, N2O is not a factor! N20 greatly raises the heat in the combustion chamber doing significant damage or excessive wear to pistons, piston rings, valves, cylinder heads, and even the block. I've run N2O on several of my cars. When I raced my 780BHP Mustang I ran the NOS 150 shot on the button and a constant 25 fog... Granted that's a lot of boost but it was new rings, valves and head gasket every 100 or so times on the drag strip. I love NOS but be prepared to modify or loose your engine and remember with NOS comes extra maintenance. That's my rant... Remember as great of a engine BMW builds they are not engineered to be beat on quite that hard. The reason the salesman said to wait so long between boosts is the more often you run it the faster it wears your motor, you car run it several times a day, just keep in mind every time you do your car looses a little life.

Ive heard that if its properly tuned it is no more dangerous then forced induction.

Whichever bmw i end up buying in the future, my plan is to do a nitrous setup on it w/ water injection to help stop any knocking. Right now its looking like a 525i is my best option since its seems like the 535i motor cant handle a wet kit.
