100%

 

That could be your problem right there.. thats what i was running and it was WAY offf.

 

anybody know of a reputable place to buy 100% meth in the jersey area?

 

these guys sell meth

= 50% power increase

 

Wow, i hope the 100% mix is a big swing in power. I am about to install my 3076 kit and I want to see race gas like #'s. I have been debating going with race gas just to get the best gains. I am hoping that 93+meth is going to be within +- 20hp of race gas. I have the AMS kit with the BIG nozzle and 100% meth and on the stock turbo I gained 60 hp and 60 ft/lbs at some RPMs (40 hp and 50 ft/lbs peak)

 

Mike I would HIGHLY suggest buying a different boost gauge.

When i went to Pruven for hte 2nd time to get dynoed I thought I was running 23psi... I got on the dyno and made 340whp.... I was like wtf... Al told me that boost guage was crap... and showed me that iwas reading horribly innacurate. Turned the boost up to 23psi ACTUALLY and power shot to 361.. yada yada.

 

to start, there is a lot of misinformation here. you really should be more careful about what you know as fact, and what you think you know/read on the internet is right before reposting it. to start, the boiling point of methanol is NOT 93 degrees. if that were the case no one would ever use it as a fuel because on a normal texas day, all the methanol would be a highly explosive vaporized fuel. not the case... it boils at 148.5 deg F that is well above any normal temperatures we will see, thus it does not evaporate very quickly. one thing that DOES happen with both methanol and ethanol is they absorb water quickly. if you tune for 100% meth and let it sit for a prolonged period of time, it will no longer be 100% meth, as it will absorb water vapors from the air reducing the concentration.
also not true. methanol will not make a o2 sensor read rich, unless you really are running rich. if the methanol and gasoline are both being consumed properly, then the o2 sensor will read normal. you are confusing a few things. first off, lambda is the proper parameter you should use when talking about a/f ratios of different fuels being mixed together. the lambda value will acount for both mixtures, and then give a value that can be used.

also meth stoichiometric ratio to air is 6.45:1, 6.45 parts air to 1 part meth. GASOLINE (calling it fuel is pretty abstract) you are correct on, 14.7:1.

for those tuning with methanol. your better off not worrying about AFR, and look at lambda. any wideband will have a lambda reading... use that. and that whole, "readings of 11.5 would be 12 on gasoline", that makes no sense. if you have a gaslone/methanol mixture and you have a reading of 11.5 AFR, that really means nothing, as you are mixing fuels, and o2 sensors don't know that. all they do is measure the oxygen in the exhaust. the sensor then sends a signal to a controller/display, which for ordinary purposes is 90% of the time using gasoline, thus it converts the lambda value into a AFR (of gasoline). if you used 100% methanol and no gasoline, that same sensor would read 11.5 AFR when the lambda value would be around .8, but we all should know that it is because the display was not reprogrammed to account for the proper AFR of meth, which had it been it would display around 5.2:1 AFR. if none of this made anysense, at least get this out of it:

when mixing different types of fuels, do NOT use air fuel ratio to tune with. use lambda!!!

 

ok,

Mike had his friend come here with a red 1 gallon bottle of "boost juice." He asked if we could run that instead of the 100% methanol mix we usually run on evo's.. The car is only runnin 26psi instead of 30psi due to the fact that the car wasn't responding as well with the 50/50 boost juice mix. The car would perform much better with 100% non lubricated methanol.

50/50 = safer
100% = flammable...yields most power

 

i wasnt knockin turbo trix or anything.... just asking for some suggestions as to why the numbers were low. my boost gauge is readin 28 psi and ill be checkin the calibration tonight. TT has been very helpful to me with my other reflash and installs.

 

DEFINITELY check that out. I ran into the same problem and was wondering why my power was down so low. Good news is its a quick fix!!! You could be running 25psi and 420whp for 25 sounds about right. Add 3 more psi and some straight meth and your numbers would be where they should be.

 

my numbers went from 310.5hp 272.5 tq to 388.3hp 396.9tq
with stock turbo @30psi dropping to 22psi at redline. I use 100% denatured alcohol.

 

i did a boost leak test today and found that the Tial BOV gasket had broken and i had a big leak there. other than that, all my IC piping was good

i checked the accuracy of my boost gauge and it was extremely close to my digital gauge.

i turned the boost down to 25 psi just bc i fixed the leak and didnt want to push it past my safe tune and it still felt pretty strong at 25.

So im hopin that the boost leak was the main cause and i can set up a tune in the near future for 100% meth.

Thanks for all your input
