I believe that DOE actually did a study and found that water/meth injection in diesel applications increased fuel economy and engine output without having any significantly adverse effect on emissions...not sure the same could be said about smokey there.

I definitely hear your points, T. And it is true that you are adding another system to the vehicle and therefore another point of failure. However, diesel and gas methanol applications differ pretty heavily as far as risk and ease. Also, I don't think many folks in their right mind would be running over 49% meth in their water/meth mixture on a day-to-day basis (which takes care of the safety items you mentioned). As long as you stick w/ lower percentages, it is literally no different than driving around with an extra tank of windshield washer fluid.

I'd love to see some aftermarket turbos for our application stateside, but I don't think meth is as bad of an option as you may feel it is.

With that said, I do not have meth installed to my car currently (nor would i install it on my past gassers) so I am not speaking from personal experience while you, however, are. I am fairly risk-averse with my modding, though, and would be completely willing to install a good meth kit after what research I have done on the topic as it specifically pertains to diesel applications.

Meth do increase diesel engine performance but only if you have problems to control egt's, which is not the case. The temps of my car are rock solid at minimum operation values. You need to sort first a reinforcement kit or a swap for the gearbox for at least a minimum of 1000nm. Only then you may need to think on a meth kit.

With 50% water and 50% meth you are pretty safe. This mixture dont burn.

Diesels do consume much more water/meth to show decent results. 1 gallon should last 10min on a race track. And i'm being optimist.

BTW, my car dont smoke as bad as the orange e90... different ecu tuning companies. Just same turbos with similar output.

I think I've seen the videos of your car, and it is definitely not Smokey the Bandit as this one seems to be.

I will be interested to see how quickly the car burns through meth with the nozzles and programming I have in my head (tweaking can always occur as needed). Ideally, I'd only like to top off the tank at about the same interval as adding fuel. As odd as it sounds, I probably wouldn't keep the system armed on a circuit track (its going to be the driver's abilities slowing me down, not the hp of the car). I would,however, keep it on for a 1/4mi track, and this is probably the only time at which I would consider running higher concentrations temporarily.

I've found some leaks in my system that I will want to get addressed (ie upper red charge pip seal) prior to any modifications, so it may be just a bit before we have to worry about having everything installed.

Once everything is done (probably early spring), I'd be happy to perform a dyno with and without the meth system armed to document actual results.

We'll see how it works out.

It is always good to see results from others members that go chasing performance from alternative ways.

Although i dont have much faith on it by the reasons that i posted above, i'm anxious to see your results.

[Puerto Rican 335d]

wow Tiago

[FormerRotor]

On the bright side, Having everything sitting around for a few months gives plenty of time to prepare for a clean install.

mike what is that

It is the meth controller from snow performance kit.

ok

[FormerRotor]

So I finished up the install (mostly) and am working on finding the right settings.

What are those of you with meth running as far as nozzles and injection parameters?

I seem to have an almost sweet spot with a 225ml/min nozzle ramping up slowly from 13 to 27psi, then a 500ml/min nozzle kicks in in tandem at 23psi. (49/51 mixture). It's not perfect yet, but I'll get it dialed in. (Note: nozzles corrected for psi of pump)

I was getting some combustion quench in the 13-16psi range from the 225 nozzle when it was ramping up from 10-20 or even 11-24.

I am running this with JBD, but hope to switch that out for another tune later this year once I'm comfortable with what's out there.

Look forward to hearing your thoughts.

Nice!

That seems similar to what I've been running the last couple years. Although I've got mine setup to ramp up with rpm's and boost, because I was also getting some quench if too much was sprayed at low rpm's and mid boost levels.

I noticed Hotrod said he was using 1200 cc/min at 100% methanol for his record 1/4 mile run. That's a lot! Not sure I want to go that high... But I have things setup so I can add another nozzle if/when I experiment to go higher.

[JDG]

How did you guys running meth install the bungs? I'm looking at doing this maybe next year and want to start planning it.

[TDIwyse]

I drilled and taped the intake pipe before the post intercooler Air Temp sensor. The methanol/water dramatically lowers the charge temp. Placing it before the sensor allows the DDE to see the reduced IAT's and change injection timing take advantage of the lower IAT's.

Ditto. I'll post some pics when not mobile. Anyone planning the install should note the above.
For now...



I think I'm going to downsize the small nozzle so that I can run it from lower (10ish) psi up to 100% at 20-22. Also, will move one of the taps (new pipe) because it is sitting too close to some lines (and likely shift them down further ipstream from e temp sensor a bit)

I'm glad to have it all hooked up & tested. Now it's time to tweak & beautify (or--more accurately-- de-ugly

Looking good guys. Has anyone out there dyno'ed before/after with meth? Clearly with hotrods run of 12.3 --- he's pumping out some serious HP/TQ.

In my head the following would be sweet:

*Reflash with raised boost
*Remove DPF/EGR
*Downpipe
*Methanol

Anyone with this extreme of a combo in the US yet?

Yes, yes, partial (DPF section gone, DOC section still in place), and yes.

I've got some info on an Evolve remap with and without some custom stuff which includes 50/50 H2O/methanol at ~650ml/min max level (so Hotrod was squirting ~4X the methanol in his runs). Also has the charge air temp data and EGT's with the runs. It was on a stingy Superflow dyno with their largest rollers so big dually pickups can be strapped on it...

http://www.bimmerfest.com/forums/sho...24&postcount=1

With the pre DPF/Ecotune mods using Evolve and stock IC/DPF this everyday methanol/custom/Evolve setup, along with some slicks, I've done 12.65 secs and trap speeds of 110.18 in the quarter mile with less than ideal winds/DA's. The Ecotune/DPF mods have freed up about about 20hp more according to my rough measurements using my in car measurement devices.

TDI - great info there and love the data capture. I'll be hopping into a 335d here soon and will also start the modding. Looking forward to what this thing can do.

My car will be a commuter, track toy and maybe yank around a small utility trailer for projects around the house. Gotta use these things!

Was it easy to set the meth injection parameters? I was thinking of getting a meth kit just to inject past 3200rpm and 20psi of boost.

Yessir, but I'm controlling only based on boost; haven't checked to see if I can tie in an additionalpoint for rpm on this controller.(don't think so).

I've got one of those stage 3 snow kits on a truck of mine .. The only options on mine are; low medium and high with adjustable gain .. With washer fluid on one of my trucks I consistently ran 88 psi of boost at 1250 egt while pulling past 100 mph ....without water on same set up I would run 80 psi of boost at around 1450 egt in the same situation

88 psi of boost! Wow. Please let me know the details on that setup. Please...
