Here is my meth kit set up - it is a custom alky control kit.

Here are some pics















I have tried every possible combination with this set up from different pumps, nozzles, injection sites, meth mixes and every possible different combination know to man

I am currently running a base Dimsport tune with dual maps via a Haltech interceptor one for meth and one without. This system alows for switching between maps on the fly.

Here is the latest dyno meth tune v non-meth tune and you can clearly see the difference. Green is with the meth map AND METH ON (tune on) the other 2 (blue and red) NO METH or METH MAP



There seems to be alot of miss-information when it comes to boost based kit as you can see from these results you can tune them, providing your tuning know wht he is doing

My question is what gains would I see if I swapped to an IDC based system? Like the Aquamist/Howertonengineering/RMW system http://www.howertonengineering.com/

There are no NO before and after charts of these kits and no deltas have been shown to see what gains can be expected with these kits and a tune.

If I can get more hp out of these systems I would swap out what I have.

If anyone has any dyno charts with the deltas using IDC systems could you please post them.

Thanks

P.S. Lets see if this one gets closed

 

I am only running one nozzle into the IC horn and I see you have two in-line. Do you have an idea as to what improvement the one in the air intake made over just the one in the IC Horn ?

It does make a difference and helps keep the S/C temps down

 

God loves a trier Damien

 

Nice info D-Man

Have you measured air temps out of the supercharger to see what the difference is without and with the meth ?

 

Thanks

 

Haven't measured air temps directly out of the supercharger, but it would be worth doing.
The IAT's are reduced when using both injection ports as opposed to just one.
I would also like to try direct injection straight into the intake manifold....

 

Would you be able to get enough 'mist' then though ? - lovely thought to cool the egg frying manifold down

Being the Meth guru and having just sold mine do you think it would work with E85 ? I was a little reluctant to run the two together whilst trialing the E85 as I know the 85% can be a bit hit and miss . You already know mine's just for the track so always HOT .

 

It would work you would just have to play around with nozzle size and may have to use multiple injection sites....

Nige meth will still work with E85, while it is not going to add much (if anything) to the octane rating of E85 you are still going to get the benefits of cooling the intake charge and combustion temps.... As you can see I am a big fan of meth for the mini

 

That's what I thought you'd say - I'll be in touch if that's ok regarding set ups as I didn't get my Devils to work - due to my own faults not the kits !

 

No problems PM me anytime

 

D- MAN Gorgeous install !! It's EXACTLY what & THE way I proposed to do the A.I.S system but "they" (ais so far ) talked me OUT of the air horn application;saying that (for their system) it wasn't worth going thru the time / $$ & trouble as the differences would be negligible ?? They "say" the intake (as you've done) is ALL thats needed? Have or did you ever try using just the intake app (block the horn) and see what JUST that application does by itself ?? I did argue the point (a little) leaning toward the dbl hoses as this IS their second option; costs more (not much) and I felt WOULD be the RIGHT way---they said don't bother due to the fact that on the Mini ALL is in such close proximity & the M45 is just NOT that efficient!(tuning?) My system may be here today (thurs) but I kinda think tomorrow is a bit more "real". The GOOD (?) thing about the A.I.S is that you can just add w/ NO "upgrades"- so THAT IS why I'm takin their word (for the moment) Tuning (they claim) IS unnecessary and "they" use the same explanation in that regard but this applies ONLY to the single nozzle install and -20 wiper fluid. SO I guess we're workin from opposite ends toward the middle with the SAME exact goal in mind; I'm gonna dyno it just as the primary install (single nozzle) Blocked on the first /maybe (?) 2nd pull then ON for the 3rd (or more) This will be & IS scheduled to be right after my arrival-75 mi / app 100k so all should be up to temp and "REAL" I (like you) CANNOT find ANY info as to the
"magic" (for the $$) with the Aquamist or is that Aquamyth??

 

I know what I would do... Save the money. Injector pulse width is determined by the following usually:

-Transient enrichment trims (in other words that extra fuel that needs to be dumped in when you stab the gas)
-RPM
-MAP
-Air temp
-Coolant temp
-Closed loop trims

Of those the ones that actually matter for a meth injection controller to get a very good approximation of how much to pump air temp, map, and rpm (due to VE reasons) are what matter. Yours is set up to run based strictly map, which gives a pretty good idea of how much air your engine is getting (this is what the ECU uses after all).

True, without incorporating transient, air and closed loop enrichments your system isnt going to be as precise as an aquamist, but it will be close. There is an open market though for somebody with a bit of programming knowledge and some free time. I would be interested in seeing somebody creating a controller using a lookup table based on RPM and MAP with temperature based trim. In that reguard the cooling mist controller seems to come close.

/me waits to get flamed

 

Gawd : IT'S SO NICE to see that there are STILL intelligent life forms out there. Done fooled around & fell in luv!! Maybe we could pass a hat?? THAT was a great post-------thank YOU !

 

All good info for sure and let me add something in more of a " real world " manner. The dyno numbers are good to see but perhaps this might give you some explanation as to how those numbers are coming about .

As mentioned earlier I have the Alky Control system as does Dman . I have not tuned my car for meth, just added it as more of a safety measure and a way to keep the power I have during those hot So Cal summer days. I did perform a simple test to see just what it did , even in such a raw form.
I had been tooling around in stop and go traffic and a quick stop to pick up some parts and my intake temp was 132 obviously very hot . As I approached the Fwy on ramp I switched on the system. I hit three gears hard and then slid into fourth. I looked over and my intake temp was 66 degrees . The real amazing fact is that it was a 92 degree ambient day. As you can see from my install it is quite simple , one nozzle in the horn, the second is for NOS.



I can only imagine how it would perform if i was to go to such an advanced set up as this piece of mechanical art

 

Thanks Fishhead

I started with the intake horn nozzle the then I started playing around with the system.
After a while I added the second nozzle to the air intake.
I did runs with each nozzle and then both.
The IC horn made more difference but I was using a larger nozzle.
Both nozzles make more of a difference (no suprise there )

 

Thanks that what I was thinking.

I would like to see some before and after dynos and the deltas with IDC kits - just to see if the added cost of these kits is justified.

As to the controler I was thinking if I could use my Haltech to run the meth system. It could give me some more options....

I currently have my water sprayers hooked up to the Haltech and set up to come on at pre determined boost and temps
Here are some pics

 

So you are running a DFIC, Aerogel blanket, water sprayer and a meth system! Was the meth system the last purchase of these four item's? I ask because the IDC systems and stock intercooler have proved to be an unbeatable pair even in the harshest track conditions. With the money spent on that DFIC and all the add-ons you could have moved up to an IDC system and still had $500 to put in your pocket.

Do a search for the RMW meth thread. All the info you are looking for is in that thread D-Man. You even posted in it .

I also recommend you go here and do some reading:
http://www.aquamist.co.uk/vbulletin/

Longboard

 

The DFIC and the water meth system works a treat.... I regularly see below ambient temps, can't beat that

The water sprayers were a little project as I started to run out of things to do with my car - but they also work very well and was dirt cheap. I like playing around with my car otherwise I would have to talk to my wife on weekends.

As for the IDC systems yes I have read all the literature available and I am quite familiar with the theory of them, however nothing beats real world testing. And I am just interested, as are alot of other NAM'ers and mini owners out there, as to what gains you can expect and what cost benefits you will see over a boost based system.

However the mini is a strange beast and what works on one car ie wrx's, evo's may not be optimal for the mini.....

I have searched the threads and as fishhead said there is no data showing the deltas of using an IDC kit on a M45 mini.....

 

Thanks MX-MN & D-MN Your info won;t go wasted and the installs--WOW !! I WAS gonna post some pics but now ?? Feels like bein at a formal get together w' cutoffs & juaraches on !! The "other fella ?? Oh well Summers comin & I've definitely GOT some bug spray. I saw That NoS bottle but you SoCal guys ARE so "trikee" that I'm STill not sure bout that----shelly or matt WILL tell me---this ais tank IS very cool and I really should take some pics before stikin it in (gawd that sounds good)---------I'll be back

 

Post some pics Fishhead, dont worry about them

 

Great setup D-MAN! And maxmini, awesome looking inlet manifold there . It reminds me of this,

 

Keep this thread civil, factual, on topic and if you have any doubt whatsoever, here is a link to the

 

Thank you for getting this back on track .

What percent meth to water are you guys running ? I have just been going with 100 % meth, its cheap enough LOL. I do not run it that often so I am not too concerned about the corrosive factor. Dman with you having that second nozzle so far up stream in the air intake have you noticed any unusual wear ?

I run 100% meth also.... just make sure your pump can handle running straight meth....some of the pumps internals can't handle it thats why some manufacturers recommend only a 50/50 mix.

As for the second nozzle I have had that on for over 30,000kms and no unusual wear. At forst I was worried about possible wear on the air intake but nothing to date
