Claims are 60 whp on a stock 535i, so you would get slightly less.

I always love it when I see a correction factor done in Standard mode to exaggerate the WHP claim "CF STD".

Who else wants to talk about Nitrous ?

I do. What does it take to spray like 250? The usual forged internals?

Hi Rob, I am really not trying to be condescending but would like to understand more.

Can you tell us your experience with nitrous? What difference did it make from your stock setup? What modifications did you have to do? If you had to do it all over again, would you have picked a different base car?

Thanks!

Can you tell us your experience with nitrous? My experience has been very good, I've never had any type of failure in anyway....just as it should be with any form of F/I. This is because I started with new quality parts & started small, then I slowly increased my HP settings as I became more aware of how nitrous worked while always monitoring my AFR's to maintain a safe level. I've come to believed that there's a tipping point, below 100 WHP & above 100 WHP. Above 100 WHP the user needs to know how to read his/her spark plugs for tuning purposes, knowing this is very important for higher levels of nitrous use. Also knowing this is why I'm a big advocate for nitrous systems Below 100 WHP, typically helping guys set them up in the 35 to 75 WHP range.

What difference did it make from your stock setup? Nitrous is great because my Bimmer runs perfectly in N/A mode as a semi DD, but when I want to enjoy it, it's there for my pleasure.

What modifications did you have to do? Click on my Vimeo dyno & read the list.

If you had to do it all over again, would you have picked a different base car? Nope, I truly enjoy my E46 330Ci.

Thanks!

I was serious... Does it just take the forged internals (pistons,rods, etc) that other F/I setups take?

Just wondering for my car if I could run a 75HP setup safely with just the stock internals.

Everything concerning my motor in that list was done (virtually) before the nitrous. But realize that internally the only things that got changed for my motor that I'd consider truly applicable to nitrous use were: 1) Head Studs 2) Ceramic Piston Coating.

A bone stock motor can easily handle 75 WHP as long as the system was setup correctly, like Any F/I system. As the nitrous WHP is increased, it's very important to use a Progressive Nitrous Controller. Just as it sounds, this unit has the ability to "Ramp In" the nitrous at a much lower WHP setting in the lower RPM range, then it builds as the RPM builds. By using a Progressive Controller the nitrous can be setup to come on "Softly", unlike an on off switch which would yield a hard hit of the nitrous.

Mein Auto: 2009 650i
I used to run a 150-175hp Gemini NX wet kit on my 2002 Camaro... loved it. I've been considering something on the 09 650i, but I'm a bit hesitant. Certainly nothing over a 75HP shot, so I'd need much smaller solenoids. As well, I'm not sure how well a BMW likes anything other than platinum plugs, with a smaller gap. I ran a controller that would retard the timing too... I don't think I can do that on this car.

As well, I'm not sure how well a BMW likes anything other than platinum plugs, They love Iridium, & Nitrous loves Iridium too. with a smaller gap. At 75 WHP, you can run stock gaps. If you did run 3 to 5 thousands less, I'm quite sure you'd be just fine. I ran a controller that would retard the timing too... I don't think I can do that on this car.
Correct, it's difficult to retard the timing on a Bimmer ECU, but it is possible.

Post up your Exact motor code for your Bimmer, I'll look it over.

Running an adjustable dry kit (20 to 100hp) on my e92 m3. The car screams with this. The only person I've seen that doesn't like it is the guy in the next lane.

Dry ??? Not a fan for several reasons.

I pray you're running a good AFR gauge to show what your AFR is at WOT....

Doubt I'll do nitrous on my F10. Just going to put a big ass turbo on it. Had spray on the Z. 150 shot stock block. Broke a ring land after not changing to my nitrous map. Built the motor and added twins. Threw an intercooler spray bar on the purge solenoid and still ran 150 shot on top of boost. There is, I repeat, there is nothing quite like nitrous. ALL AT ONCE...KICK IN THE PANTS. I'll see if I can find the nitrous only dyno. Went from like 240 ft/lbs of torque to 433 in half a second. I had a stiffy for an hour after the first run.

edit...

I cut out a gym bag on the bottom, wrapped it around the bottle and zipped the top. No one could ever find the bottle. Even after I asked them to look.
