that .7 is a flash from the PCM's burst knock setup. .. over 21000 miles and 0 motor issues so far

 

meth can be found online (boost juice, vp, etc). or at local performance shops or race tracks, or at local farms that use it to make biodiesel...and it should be 3-7 dollars a gallon...

some water has minerals and deposits in it that can over time clog the nozzle...

alky has different stoich value but tuning is much the same, you can push the car to "leaner" afr's but in reality they aren't always as lean as you would really thing they are...

 

when running meth do you have to advance your timming, or can you just run it for its IAT cooling bonuses. i was thinking about running a low or smaller spray of meth just to lower IAT... i just dont want to advance my timing right yet. i konw its not taking the full advantage of meth but would it hurt to run it without advanced tuning?

 

Maybe look into smc injection kits sold by rjcracing.com, I use it on my 86 Buick Grand National and I run 23 lbs of boost on pump gas with no knock. Just FYI.

 

you could certainly do that but you would be leaving a lot of hp on the table...

 

I have a meth kit and I can run more timing with no KR but my IAT2 temps aren't any cooler than before at all. What gives?

 

where are you spraying, you may be spraying after the sensor and hence it won't read lower...

 

hmm, well i guess i will have to look into that more when i do an install on our cobalt when we get it...i guess the blowers making so much heat that its not effected by the meth injection...

 

Ya, I'm spraying before the blower aswell.

 

more meth = cooler temps... I usually run 75% meth 25% water

 

no prob... I never run less than a 50/50 mix for that reason

 

I got s&k speed around here... but check with VP fuels and see if you have a local vendor for M1 racing methanol

 

anytime man.

 

bump for some mor meth addicts in the making...

 

Hooking up a Alcoholinjectionsystem.com kit right now. Worked great on my GTO will see how it works on the Cobalt.

 

what is the best system out for meth i have heard snow performance is great. what is the 2.5 bar thing?

 

Well... I'll admit I'm clueless so I have a few questions.

Is meth something you can install without a tune primarily for the cooling effects? Once I drop pulley sizes I will get tuned but until then is it safe to run without a tune specific for meth?

I would assume not due to the fact that it raises octane level.

If I were to run out of meth after I have been tuned for such, what kind of problems would this cause if I were to drive without any meth for some time?

 

^ anybody? ^

 

don't beast on your car if you are tuned for meth but don't have any at the time that could eqaul massive detenation

 

I assumed that much, but rather is it okay to drive for some time (driving normally, not WOT) until I can get more meth?

 

One question, (the same question I've always been posting) do you guys think the meth injection could work in lieu of the 50 shot of nitrous for the GM Stage 3 Kit? I'm going to purchse the stage 3 for sure, but not sure whether to use water/meth or nitrous. By the way, does anyone here actually have the GM Stage 3 set-up?

**update**

In answer to my question, no it doesn't work!!

 

I ran both for a long time with my evo with great results...i went from 110 traps to 123...

 

well ive been readig and reading and i like the idea of meth injection.... so what are the side effects? does it hurt anything at all?

 

Some info I thought I would toss out.

Spraying after the blower is more efficient, but you don't get the cooler blower. IMO I would get 2 smaller nozzles and have one before and one after. Right now I got 2 spraying after and going to try routing one of them into the intake.

Also, water actually lowers the temps better than meth. Meth is used for added fuel. 50/50 mix is optimal to get the best of both.

 

OK can i add the 50/50 meht/water after my cars tuned? Than if i run out it wont cause lsj death...
