I have a few questions, I never have used a meth kit before:

So I bought the AEM meth kit.

It includes:

1 Gallon tank with built in low level switch
Boost referenced progressive controller
“Boost Safe” readiness safety system
Check valve integrated into nozzle to prevent unintended fluid flow
One injector and three nozzles to cover a wide range of HP levels
High Pressure Recirculation-style pump
LED dash light for system status and low fluid warning
20 ft. of injection tubing
I also purchased an injection filter.


1) Am I missing anything that is critical to this system working properly?

2) Where am I going to drill to put the nozzle? Pre turbo in the aem intake or post turbo in the zzp upper charge pipe?

3) How much meth am I going to need for my tuner to get my combo tune fully dialed in? (I heard it is an extensive process)

4) How do I mix the meth and distilled water? 50/50 by volume or is meth less dense and I need to have more of it?

5) On my select-a-tune feature, does the base tune need to run on meth as well? It would be a nice to have a 22psi base tune that would be good for circuit use.

Any help is appreciated.

Thanks.

 

Your missing a pipe and a lighter

 

Funny, I thought someone would post something like that

The internet is %!@*ed. After my post a few of the advertisements I get -> 1. Become an addiction counsellor 2. Are you struggling with addiction and need help.

 

You will need a retune for the meth injection. It will effectively up your octane when the meth/h20 is injected. This will allow you to run more advance and take advantage of the power. The injectors should be after the intercooler... Like right after it just so the water won't condensate in the intercooler and mess up your intake path with big beads of water. The best thing about meth is that you will be able to run more boost because you will get a denser air charge, and you can run more timing advance when you are injecting it into the intake. The amount or % of meth you will use varies depending on ambient air temps and your tune. On the truck in my sig the meth lets me run about 5 more psi of boost... the 6.5 liter is not a boost friendly diesel so meth really helps... In my truck i pretty much run washer fluid, but you can get meth/h20 fluid premixed from devils own. They have good stuff, or you can mix your own. What are your mods now? Do they support a good meth kit? For example, DP, CAI, CPs, and Intercooler. These all allow your motor to breath better to take advantage of the meth kit and let you boost higher and more efficiently. I hope I helped a bit rather than just confusing you further.

 

Even with the meth, I'm not going to exceed 24psi on my combo tune. I realize it needs to be updated.

AEM cold air intake
ZZP catless downpipe
zzp upper charge pipe
muffler delete

 

Hmmm well I would say that meth might not even be needed at that point yet... usually meth is only used to push more boost or help with IATs. If its your goal to use meth then by all means do it... Its awesome but with the mods you have it probably isn't needed yet. You could probably do different mods for less money. I would say maybe wait for a turbo swap to do a meth kit... That way you can safely push more boost. Meth is still great to cool down the air charge though and get you some more power due to added spark advance and more octane in the meth... as well as meth already has an O2 molecule attached so it will burn with more power and richer than just normal primo but it won't able as noticeable.

 

My tuner and I were doing pulls in the TC on the dyno, and the IAT2s reached 172F. Rediculously hot as in Supercharger hot.

The combo tune is already pretty effective, for me the meth kit is to make the motor last longer, and add a tiny bit of power.

 

if your seeing 172 IAT then your having some serious problems and meth would be a band aid. i never saw more than 110 at stock turbo 27 psi and stock intercooler in 90+ degree florida weather

 

Yea but seeing as it was on a dyno thats not really that surprising. Heat soak can be a bitch.

 

This. Sometimes the fans do not move enough air to keep the IAT2s where they would be on the streets.

 

Did they not have a fan pointed at the car?

 

Tuning on dyno suck ***** lol somewhat.. has its pros and cons.

 

I was talking about on the dyno even after half a dozen pulls in 90+ degree weather i never saw more than 110 hell at over 5k rpm it would pull down to 99-101*. are you other guys really seeing 172 IAT on dyno pulls

 

The 172 was obtained after multiple pulls (I would say over 6) on the dyno. We were testing a TF/HP combo tune 24psi we put on the car. Mostly 4th gear pulls.

There was a fan placed there and it was working properly. I realize my car is likely never to get that hot again on the street when air is moving that rapidly.

We took the precautions and cooled things off.


I just want to get the most out of my stock turbo, so why not add meth since we have no e85 here in Toronto.

I have done alot of research on these turbo kits, and I don't think I'm quite there yet. I'm not sure if I would be happy with 420/420, so I think I'm going to enjoy it on the stock turbo for a few years.
When all is said and done (and more research done on these cars and better transmissions are available), i'll probably do an engine rebuild plus larger turbo (600whp).

If I blow my engine or trans now, so be it, but we all know the limits of these cars so I'm not taking it above it consciously.

I'm not willing to spike my boost pressure past 24psi, because over long term we all know what happens to the pistons.

 

Alright well

1) I recomend a solonoid to stop the meth from draining into the engine when the pump is not on snow performance sells them.

2)neither your going to drill in the coldside pipe post intercooler. I recomend you pick up a zzp one but you can always drill into the stock one.

3)I make mine in 5-10 gallon batches it doesn't go bad as long as its sealed so i'd just cook up a big batch and have some leftover and you won't run out during tuning i went thru about half a gallon when tuning.

4)you just pour it in the same container. yes the proper way is to do it by weight but nobody ever does it just do it by volume and save yourself the headache there is little to no differance between 45/55 or 50/50

5)most kits will start spraying at X psi so if your base tune hits the set psi i imagine it will spray the meth.

your smart not taking it past 24 thats what killed mine

 

170* is crazy high! That shouldn't even be possible with no fan on the car. The highest I saw when we forgot to turn the fan on was 120-130ish. Were you doing back to back runs??? You need to give the car 10-15mins between runs to cool off. Otherwise the data you are getting isn't "real" either!!!

 

The place where I dyno do runs, back-to-back-to-back. 3 Dyno runs probably take less than 4 minutes. Hahahaha.

 

how much power can u get running meth on a tc

 

We were doing runs with a break between them, but not 15 minutes.

Thanks Blackvette, I was hoping someone would answer my questions eventually.


I was aiming for 340whp 375wtq with these mods:

ZZP Catless Downpipe
ZZP Upper Charge Pipe
AEM Cold Air Intake (new version)
Muffler Delete
TF/HP Combo Tune 24psi, with no boost spikes
AEM Meth Kit 50/50 Mix
