Good morning,

For those following the thread, my Z06 will soon be in the hands of Manny, with luck this week. The 3rd component of the build will be a Alky Control methanol injection system to help lower the intake air temperature. I sort understand the whys of this but then when others started to post on anotehr thread it gave me a few more questions.

I understand that since this will be a very tune specific job that I need to decide the purity of methanol to use beforehand.

MADDOX has been sharing his experience with methanal injection with me and he's a 100% man.

Not that it is a big deal but running 50/50 and still being able to use the wipers sort of amuses me. Plus being able to carry around a jug of windshield waasher fluid and being able to buy this anywhere is sort of appealing too.

But if what I have read is correct, going from 50/50 to 100% results in a further 3% hp gain. As this is a matter of what product to fill the reservoir with and the tuning work which is done, it sounds like an option I should seriously consider.

Now my understanding is that if you use 50/50 or 100% is a decision that I have to make BEFORE the tune is done and that I can't go from one to the other afterward without having the car re-tuned which is not something that I can easily do.

So I was wondering for others of you with methanol injection on your FI system, which way did you go, 50/50 or 100% and why??

Maybe Manny can weigh in with his thoughts please.........

I sure appreciate the help!

Cheers,

Garry

I have Alky system's on all our cars , and most run in the summer only , and boiling has never occured , even with our hot summers here . 100% meth is the best way to go , why dilute a product that works best at 100% consentrate .
Julio , who developed this system in Mami Florida has never had this issue either ., and we know who hot it gets down there .

Some of my clients do long hauls with their supercharged and meth injected system's and have had zero issues. These guys are driving up to 6 hours at a time .

All the cars that we we do run 100% meth in the washer tanks . If anything I would use a second tank for the washer fluid if you were really concerened about being able to wash the windows .

As for the the meth running out . We move the IAT sensor behind the the Tb and in the intake , so that if you do run out , it will be seen right away on the sensor and timing will be cut back right away.
 
Good evening Manny,

Living the dream here, alive for my son's 8th b'day, mom and dad were over, cake was great, son happy with presents, it doesn't get better than this.

Thanks for the info.

Is there a particluar brand of methanol that people use?

Anything to stay away from or beware of, methanol with additives perhaps?

Do most skip the being able to wash windows and just use the windshield washer fluid reservoir?? Does anyone wash windows with 100% methanol or is there a fire hazard?!

I really enjoyed MADDOX's video clip - I can't wait to do that myself!!

Cheers,

Garry
 
Remember meth is only spraying when your in the boost

What spring are you going to use in you blow off valve ?
 
Good evening MADDOX,

Yes, I understand that. No gas pedal applied, no massive volumes of fuel running into engine, no need to cool air or advance timing, no need to apply methanol.

I'm not sure what spring is being used......which ever one comes with the Alky Control kit?? What should I be made aware of?? Does the purity of the methanol come into play? If the Alky Control system was built for 100% methanol what is the potential problem?

Cheers,

Garry
 
The Garry the Spring Maddox , is talking about is in the blow off valve for the Supercharger kit .

The answer is: the one that Andy send's with the kit . This is not a custom application , so there is no need to change up any of the parts that A&A have researched to work together as a kit .

The concentration & brand of the meth really has little bearing . It does not matter where you buy it or what brand you use .

All of the systems we have done did not get a seperate tank for the washer fluid . Again its a personal choice if you want it .

Its not at all advisable to use 100% meth as a washer fluid for your windows : 1 because it is and can be flamable & 2 it will eat your paint .

Thx
Manny
 
Good evening Manny,

So any old methanol will do. Good to know.

Why would Maddox wonder about the spring in the BOV? I remember you mentioning that you were going to set it to 7 psi (?) but that was about the only time this area came up.

Funny that so many would give up having windshield washer capabilities. I'm sure most of us are fair weather drivers but I wonder why? Can't be room or difficultly in mounting a 2nd tank. Any idea pro or con-wise?

Garry

Garry , not really sure sure what Maddox is getting at with his spring question .

Boost is set by the pulley size we are runnng , in your case its a 3.8 . The spring is in the the blow off valve that releases excess boost , much like a waste gate on a turbo .

Most people try very hard not to drive in the rain , so most do not need the extra tank for the washer fluid . Again its a personal choice, you can always run a small bottle , or as I've seen you do a squirt bottle out the drivers side :rofl:

Sorry I don't mean to start any problems here or cause any

I just thought if you went with a #3 spring it would take more pressure of the head unit
that all

This is why I dont really post on here I just read :seeya:

Guys guys guys! There are NO PROBLEMS at all here, at least with me!

You're right though Manny. I remember coming back from Peace River and it started to shower and I just hoped it would hold off for 10 minutes until I got home. Rain I can live with if I have to but the spray under the car I don't get too excited about.

Squirt cleaner with a bottle? Now what kind of a wingnut would do that??!! If you didn't follow the earlier posts MADDOX find 'The journey of my beloved Z06 begins" for a laugh perhaps........looking back at the trip now I sort of have to shake my head a bit. But it makes for good story telling at least!

I'm glad that you have posted on these threads MADDOX, as with Manny and the others I appreciate your input and experiences. This is a new road for me and the better informed I am the better.

So I hope you won't fade out on me please!

Will you share the type of spring you are running? How much boost are you running?

One of the ZR1's at Race the Base this year was running 15 psi I think but the turbocharged Supra was running like 40 psi! Is there normally such a difference between SC and T boost pressures??

You can run much higher boost pressure with a turbo .

So for Maddox , Andy's systems are built extremely well and I am not aware of any headunit problems due to the spring used at the BOV .
Again this is not a custom blower build , but an off the shelf kit that has proven its self time and time again , so why change anything :D
 
Good morning Manny,

I would suspect if anything occured with a spring failure of getting weak it would simply open earlier and not later so there would be no over-boosting???

Maybe there would be merit in a boost gauge????

Garry , I have yet to see that happen .

There is no merit in those gauges . If you really want them I can install both the AFR & Boost Gauge for you .

Personally for me I think they are just not needed .
 
Good morning Manny,

I feel so bare without new gauges! How about a shift light? Same-same?

Cheers,

Garry
 
Good morning Manny,

Yes, I know that you would. But your point is certainly correct. I shouldn't be looking a gauges when I am driving at a spirited pace. On the other hand, maybe my passenger and certainly my son would probably find it entertaining. Something to think about.

Maybe I need to do a gauge thread. As has been said of Riley, I'm such a post whore!

Cheers,

Garry

Manny, I have to disagree. Knowing what's going on with the engine can definitely alert you to a problem before it becomes a big one. For example I once noticed that my boost was a little higher than normal under light acceleration, and sure enough after much investigation, it turned out my cats were breaking up and starting to plug the exhaust.
Of course someone would have to be aware of "norms" and have some knowledge of what to look for.

Let me rephrase it then , For the average guy , they have no meaing , since most do not understand what they are reading . Just pretty lights .

I have yet to install a gauge pack for anyone that was able to really say they were looking for or at . So for the most part my first statement was correct .
 
Good morning Canuk, Manny,

Hey nice to see you have a sense of humor Canuk, cute pictures!

Maybe you could program in a set of guidelines for the alarms to be sensitive to go off at. I might not be aware of what the problem might be but it sure would be nice to know that I am in a danger area. Sort of like I was mentioning before about idiot lights. I don't need to have the oil presure reach 5 psi to see a light coming on. If it is always rock steady at 50 psi and suddenly starts to read lower I'd like to be aware of that. While I might not ever tackle a forged engine with this car I'd also rather not have to face finding a replacement for it either as we know what tracking down a LS7 can be like. I like to think that I am a teachable sort of guy and knowing good numbers from bad would be useful..............

Canuk, any idea what caused the cats to fall apart like that????? I grew up in Kirkland on the West island in the mid-70's, really enjoyed living there a lot. Went to school in Beaconsfield..........

Manny, does the range of AFR vary from car to car or is is constant? I remember Juan with his FD telling me that the range for him was 12 to 15%...........

I should be able to send you the proper number this morning as well to correct the other issue, I called for it last night but the owner was in bed.

Cheers,

Garry
 
You a funny guy Garry :rofl:

The AFR always varies from car to car and system to system .
