Anti lag is will destroy an exhaust system that is not designed for it. I think in my case N2o is the best bet to keep it streetable

I plan on running Robert's nAst1 code (staying OBD1) this spring and I believe he already has anti lag implemented in it. The only time I plan on using it is at the strip or the occasional need to beat someone off a light if I need to merge or something. . In other words I won't use it a lot, but it will be nice to have on hand.

i imagine launch mode could be used as spark retard anti-lag, but i haven't specifically added that to the program...... yet. if i do, it will have to be when i add closed loop boost control, that way it stays in that mode for the shortest amount of time possible.

the three-step rev limiter may or may not be useful here as well.

Hmm I wonder how I can set it up in HPtuners. Im going to the track tonight and I might try and see if it helps.

I wasnt able to figure out how to setup an anti lag with hptuners but I did set an new PB

I wouldn't bother with an electric motor on the shaft. More to go wrong and turbos can spin (not down like my phone previously swyped) at over 100k rpm. As for the injection, basically what you are talking about is how anti-lag works. Anti-lag with the ecm works by retarding the spark so late it fires late enough that the combustion event is still happening when the exhaust valve is still open/opening, raising EGT to spool the turbo faster.

I agree however I am curious with BMW's new turbo concept.

BMW is working on a turbo that has an electric motor with a series of clutches. The electric motor spools the turbo up and when the engine catches up and powers the turbo the motor turns into a generator. As it has it, the generator restricts the turbo w/o needing a wastegate.

The turbo can have a seperate electric circuit/battery to spool it up and recharge during boost. I bet excess charges can be leaked into the main circuit reducing alternator parasitic loss. Which is energy otherwise wasted through the wastegate. Though this is just my assumption as there may be less efficiencies or some real time issue reducing the potential gains.

I didn't read what voltage it operates at. I imagine a higher voltage would benefit due to the loads involved as the amps would be very high at 12v.

Interesting stuff those germans come up with!


It’s been reported on these pages before that BMW was toying with the idea of an electrically-power turbocharger, and a new patent suggests the German automaker is moving forward with those plans.

BMW has officially submitted plans for an electric turbo to the the German patent office, suggesting the technology could become a reality in the not-too-distant future. In fact, the next-generation M3 could arrive with the technology sometime in 2014.

Working in tandem with a larger, conventional turbo, the electric unit use a small electric motor to power its turbine during the transition from idle to load, which BMW says greatly reduces the phenomenon known as turbo lag – the period it takes a conventional turbocharger to spool up. In addition to boosting performance, the electric turbo also increase fuel efficiency as it helps keep the engine in its optimum operating zone.

BMW has yet to announce any production plans for the electric turbo, but the time is certainly coming. The German automaker will likely initially use the electric turbocharger on its higher-end performance cars to defray development cost, but the fuel-saving technology could eventually spread to lower-end vehicles.

I know :P

The electric motor on the turbo reminds me of those cheap ones on ebay.

I wonder if I can machine a N20 nozzle just right into the housing that the pressure helps spin the turbine up.

Back pressure would be an issue unless the point of injection was aimed directly into the turbine blade. Odd number of injected versus the number of blades to spread the load. Like having 4 blades and 3 evenly spaced points of injection. Each blade will recieve a push between the next promoting a smoother spin up.

Viktor Schaubergers work on vortexing gases and fluids was beyond his time. He was working for the Nazis and had his hands in turbocharging turboprop aircraft.

He was well ahead of his time. If you like to invent better ways of turbocharging, his work is worth looking at.

edit: the idea of drilling into a working turbo is, hard to do. Unless I had the cash to burn on 2 prototypes.....gets expensive going into serious mods like that. And thats if it even works, lol.

I think the best solution so far was roberts code or some pcm that can control boost.

My brain hurts just trying to think about his work.

lol, knowing how a large mass of air with low momentum efficiently converted to high velocity vortex. Spirals within spirals making a vortex with 2 main ropes. The outer edges of the vortexing air flow become super heated and the center become chilled, by hundreds of degrees if the right conditions and flow is met. Bleed off the hot side, controlled, and the intake becomes much cooler, moving in a self sustaining spin within a spin.

Somehow get the engines vacuum to drive the flow in such a way, same as applied pressure on the other end. An oversized hilsch tube intake cooler.

The company I work for bought a Korean turbo blower manufacturer. They have a centrifugal compressor with integral electric motor (industrial applications that cost more than most cars). It is possible to make one for a car that's 100% electric, but it takes a lot more effort than e-bay and Chinese knock-off companies put into it.

BMW's effort of mixed electric and exhaust drive sounds like a nice compromise, though one that may be overly complicated.
