lol I wish. But those emissions checks will catch up with me🤣🤣

The problem is not knowing the exact octane you will have and tuning for what you think it has increased to.

BLKROKT

Here's some data. I suggest reading up on meth. You'd have to spray an insane amount to add any meaningful octane. To go from 90 octane to 95 octane, you'd have to spray ~20% vs gas. Good luck when that runs out. Please post pics of the hole in your block. If you ever get a C63 of course.

Most people who know anything don't run meth to raise octane, but to lower IATs.

Set up the meth system before the tune and see how it reacts. Spraying doesn't add enough to affect BOV so you'd have to mix in the tank. If it's not pulling timing try a 91 tune first to be safe.

If you're mixing on the fly you have to account for running your meth tank dry. Don't rely on it being available

As for the other posters saying meth won't increase BOV. They're fkn clueless. I think it was just your initial delivery that rustled the sensitive feathers.

EDIT: Yup, missed this last page of replies when I posted.

RA81722

thank u for saying that. Thats what i mean. Meth has been known to boost octane and let u run a lower octane gas by at least 3 points(being Safe). The gas problem is unique to alaska. Its ether meth or torco, with will be more expensive for one but more importantly its a pain to have to get it everytime u fill up!

RA81722

or maybe just get an upgraded 82mm TB

meth adds octane...sure, but if you're tuning for meth without a standalone, you do realize meth WILL run out. with a standalone you can configure map switching or things of that nature, but honestly at that point you'd simply go alcohol injection. Meth injection is popular mainly among the VW crowd because the VW crowd seems to try to push the most power out of the smallest turbos.

if you're honestly worried about 1 octane difference from say...California 91 octane, you're really just what people in industry call a "bench racer". Any tuner can knock down the timing map 1-2 degree's before sending it over to you. in addition all this talk about Alaska, you have COLD air...you are actually less conducive to seeing knock than the rest of us in hotter climates.

people that actually DRIVE their cars don't worry about things like meth. run what you brung or so they say.

RA81722

umm the VW crowd didn't popularize meth dude.
tuners have been using it for a long time and companies like weistec use it in there e63 builds. Its not just one octane point, the octane boosting capabilities as discussed are like 10 points. How would u run out with a 5 gallon tank in there back? you might refill every 1000 miles id guess

your right we do have colder air, but that doesn't make up for crap gas.

doing research isn't bench racing bro, so don't insult my intelligence.

BLKROKT

Your method for asking for help and opinions needs some improvement

hachiroku

wow bro. get the **** out of here.

BLKROKT

Dude. You would go through 5gal of meth per every 90 octane fill if you wanted to raise your octane 3 points. It's math. The stuff isn't magic like Boostane.

Ludedude

Boostane FTW!

BENCH RACING

1. To discuss the possible quarter-mile elapsed time (E.T.) of a car based on a list of modifcations or horsepower estimate.
2. To discuss the estimated output (in horsepower) of one engine versus another based on lists of modifications done to each engine.
3. To discuss "which is faster?" or "Which would win in a race?" between two cars, based on 1 and 2 above.

http://www.urbandictionary.com/define.php?term=askhole
ASKHOLE

1. Someone who asks many stupid, pointless, obnoxious questions.
2. Someone who consistently abuses internet fora and discussion boards to post stupid questions a quick google search could have easily answered. Usually withholds relevant information so that even posters trying to help cannot really solve his problem adequately. Utterly disgraceful and quick to insult anyone who refers him to google or other sources.
3. A person who constantly asks for your advice, yet ALWAYS does the complete opposite of what you told them to do.
4. A person who repeatedly asks for advice from multiple individuals, only to ignore aforementioned advice completely. The askhole will choose the least logical option (usually their own), skipping merrily down the path into unbridled oblivion, blissfully and willingly oblivious throughout the entire ordeal.

We can conclude that an "askhole" is a gaping, cavernous pit of stupidity, into which good, sound counsel is thrown and subsequently lost forever.

RA81722

😂😂😂 it really shows u no nothing when u say stuff like, the vw crowd pioneered meth injection

RA81722

it’s not injecting all the time dude. U can set it for a specific rpm like 3500 and up. It would depend on how much u step on it. 5 gallons squrted there a tiny nozzle would not run out with every tank of gas.

Edit, just forget it

This sounds like a boom waiting to happen. Now we're onto only part-time spray that's RPM dependent, on the stock ECU. On a car with instantaneous throttle response.

roadtalontsi

just forget about real world n/a 500whp. the only way thats going to happen is on e-85

forget the underdrive pulley - spin the water pump, a/c and alternator slower? remove important dampening characteristics. id pass.

having a separate ecu with a race gas tune will help get a little more.

on n/a cars intake air temps arent nearly that big of a deal. meth is a waste of time.

mct in a 204 is rated for 1000nm


as for poorly designed intercooler on the e55 comment. i guess you've never looked at any other roots/twin screw intercoolers and where they're located?

RA81722

on top of the poorly designed intercooler the supercharger is not clutchless from the factory, leading to rough engagement. which further adds to the bad supercharger design that I talked about. The intercooler being a bad design is already something that’s been settled along time ago. Look at the Cadillac CTSV, that has the intercooler on top of the supercharger in the lid of the supercharger. That once doesn’t get heat soaked

RA81722

is that 1000 N meters at the wheels or at the motor ?

Ambystom01

Why did you quote yourself to ask yourself a question?

hachiroku

seems you know everything about everything. I wonder why you aren't getting paid big bucks to lead the head of engineering at AMG...oh ya that's right you're a ****.

hachiroku

Jasonoff

Usually the controller will tap into RPM and manifold pressure to calculate pulse width. So it's always part time spray. You don't just dump in meth for no reason...

Have any of you guys making comments actually set up a meth system?

Edit: Just curious. Don't get all offended or anything...
