Maybe i am way off...probably.

u dont put the tank in the engine bay...duh...i ran this in my gtr and i was able to run higher boost with no problem !

but theres a bad side to this as some ppl say they create moisture in the block and will rust inside the motor.....

There is condensation occurring inside an engine every time you start it when the weather is cool and it will dissipate after about 6 or 8 miles of driving. One cool thing about water/methanol injection is that it steam cleans the combustion chamber and the steam exits the engine during the exhaust stroke.... If you are putting too much into your intake you are gong to quench the plugs and have to disconnect the coils and crank the engine with the throttle held wide open to clear it.

Wow great thread with awesome info. My buddy has meth inj on his STi and loves it.

yeah, i made an album with some pics of the kit in it (cuz it seemed easier than postin them all in this isnt there a way to just take jpg images and just paste em in this little box....no html blahblah? owell)

And its a Snow Performance Kit.. even tho the name of this thread is AEM...
The car goes into be tuned next monday. even tho it was supposed to be today but they rescheduled me..

I don't think it will be much different from the original tune. All i did was up the boost 2psi and put the Meth kit on. I'll just have to wait and see.

well the car is tuned and the meth didnt do much for power because advancing timing with the fit's L15A motor did not add any HP. it actually lost a bit when they turned it up the first couple of degrees.

So I got +12hp and +20tq so i now have 156whp and 167wtq
The Fit is also an AT paddleshifter so any more of a gain that this would most likely begin to damage the Transmission, Which was my main concern.

Well you have got me sold. That is a hell of a power gain from something that will extend the life of your combustion chamber. The system buffers the initial explosion at ignition in addition to cooling and cleaning. It also lowers exhaust temperature reading by the O2 sensor. What are your A/F ratios. and ignition advances when it is squirting juice..... I don't think that it is advised to use more than 50% methanol to avoid a possibility of combustion in the intake manifold which can become a disaster on a boosted motor.... Instead retune with some nitromethane in the mixture with 50% water.... You added more boost so it is no surprise that it couldn't take more timing advance.

+12hp & +20tq is a nice gain considering the tiny motor we have.

I would rather see a larger torque gain than horsepower on a small displacement motor with street gearing any day, and oh so much more on an automatic with such tall gearing.... I would be happier than a possum eating cow shit..... That is big time oozing with happiness. I'll tell you.

yeah the fit is running well and i can feel that little extra bit of torque in the later gears, which is a nice feeling

with meth injection before tuning a/f ratio was in mid 13's, and now after tuning its like low12, low 12 ,low 12 then dips alittle to high 11's ... (lol i'm staring at the graph line... not an exact science...eyeballin it like this.....)
basically right around 12, i dont know the exact number.

The snow performance kit uses a vacuum diaphragm switch which uses boost pressure to tell the pump when to turn on. ( and the more expensive kits[cuz i just got stage 1] have like a cool little controller so you can do/set everything up on it in-cabin blah blah coolness...)
I set mine first at like 4 psi, but once the first dyno run was done, they let off the gas and the car bogged n died. lol, i had it putting meth in too early so i adjusted it and it is set to come on at like 4.6-4.8psi, which works awesome.
so if you get the kit just dont set the meth too early and it'll be amazing, cuz the install is pretty darn easy.
