NOS with the TS2?

Hello all. I did some searching on the subject of including a 50 wet shot of nitrus oxide with a supercharger setup. On the general subject, I found that people were having success with it on camaros and mustangs. It was indicated that this was even safe to achieve with using a small shot of NOS and a proper tune. I understand that this is clearly a straight line performance thing and wouldn't by any means be a frequent use thing.

When I dove deeper into the subject, I found nothing on FI E46 and NOS together. Its either one or the other. Now I'm asking (I know it can be done) what is the viability of doing something like this? I know that the M54 uses a steel sleeve for the cylinder liners. But how strong is the rest of the block for something like this? would it be best to use an S52 block and the M54 head instead? This is all pertaining to an engine build in the future using forged internals and eventually moving to the ESS TS3 kit. Which would move to using a 15lb pulley and so forth.

I'm aware that AFR's are very important in any performance situation so more rich than lean is always the way to go. NOS is just such a cheep power adder to be totally overlooked. Any input (not haters or flaming) is appreciated.

My ONLY concern would be this: Is it "OK" to spray atomized fuel in a small quantity through/past the rotors of the TS2/3 S/C ?

IMO, everything else will be straight forward & easy.

Yeah, that was my concern as well. It would be easy enough to mount the nozzle in past the screws. But I'm not a huge fan of drilling into really expensive cast pieces... I would probably have to call up Lysholm and see if its safe to spray before the screws or not.

Yes, call them.

The nitrous gas would never be a problem, but the small quantity of Gasoline may or may not be a problem.


Good luck,

I ran a 75 shot for 2 years with no problems with my TS2. Sold the kit and went meth with TS3. Only got rid of it because I couldn't run both.

Could anyone with a TS-kit try to find out if the Disa valve is still activatable? Just plug a voltage meter or a small light bulb (12v low amperage) into the connector and have a ride. if the light goes on/off we know its still usable and configurable for our needs, like activating a solenoid for fluids or gases

That would be slick.

Nitrous controlled by re-purposed DISA circuit. (Software reconfigured obviously)

That is an awesome idea! I never would have thought of that!

Were did you mount your nozzle? Before or after the screws? Was it a wet shot or a dry shot? How much (or little) work did you have done to the internals while running the NOS? Thanks.

That was on completely stock. WOT switch, 75 shot before the screws. I had full set up, bottle warmer, gauges, progressive controller (never used) all NX Express, Nitrous is great when all conditions line up. I an too impatient for it. Dont like waiting for bottle pressure, bottle warmers, constant trouble shooting, etc..Its cool for the track but not ideal for me for the streets. Its safe as long as its done right. I know a guy that does a 200hp shot in him M3 (all stock).

Being disconnected does register a fault code. I'll drop an e-mail to ESS and ask them

Nope, DISA fault is deactivated, at least we can deactivate it

We just need someone to confirm if there is still power on those wires and if not, we need to find where they switched it off.

On a stock BMW engine, on top of a supercharger system, nitrous will help shorten the life of engine.

You may spray througout 1st and 2nd gears but if you keep on spraying all the way till the end of 4th gear you will soon remove cylinder head and rebuild your engine.

So we could use the exhaust flap to actuate the NOS valve, its gear-dependant

Well, iŽll have a look at how to find it out and post some instructions.

I tend to think they just disabled the error message, rather then completely deactivating the solenoid.

Very cool! Good research paraklas. Thanks for getting in touch with Hans. It would be very cool to see if that would work with either NOS or a meth injection (which ever a user may prefer).

Alright, just plug in a voltmeter at the contacts from the disa connector, set it to -20V/dc and switch on the ignition to second position. If the Disa valve is still active, there should be ~12v even without the engine running. At idle there should be ~12Vdc, too.

If thats the case one can use that connection to switch whatever they want at load-dependancy
