That would explain that I did not experienece any hesitation on my car, part of the reason is because we start to spray at nearly 18psi.

By the way guys, I spent a few extra minutes asking the "silly" question to Steve from SMC. One of my "silly" questions was about the ending psi seting on the second dial(26psi), he told me that the number 26(max) is there because they really di not have more room to imprint the higher numbers but that the system actually max out at around 29-30psi.

I hope we have a better idea on how the SMC works.

Carlos, my low setting is 18psi and the high setting is 26psi.

 

haha i'm workin on it!

 

you dont really need to tune period....it only helps ,
i didnt see any power difference maybe alittle between after and before the tune with methanol kit...
im a methanol lover~

 

That is not possible. If your meth really works, then your AFRs went down 2 points as soon as you activated it. There is no way you can get the same power before and after tuning, because with tuning, you remove TONS OF FUEL to get the AFRs back _AND_ you add a lot of timing that wasn't able to be used before the meth.

 

ask al........!
he only adds 1 degree of timing .....

 

Did he give any kind of timeline on when the failsafe would be available?

 

he does not respond to me

 

I don't have to ask. I was right there watching every step while on the dyno. The moment I turned on the alky and boosted, my AFRs went into the 9s. If I didn't retune, I would have about 40 less whp, if not worse. He had to pull a ton of fuel and gave more than 1 degree of timing. I did a lot of timing, especially with the ported/coated Buschur parts.

 

so clayton what are your mods now? how much more HP are you making since the 12.2 and the 12.0 runs?

im still interested in finding out whats better alky or meth, or same thing pretty much?

also wondering if you run this all the time, how long does it last? or is it one of those things you only use at the track and have a special map for it?

thanks

 

go for 100%methanol !
you dont wanna mix with water

 

Do you need anything after the alky kit is installed for a tune? Like a wide band or something to control your timing?

I personally do not pull much if any fuel on alky tunes. I don't feel it is safe to do it, it costs me some power I know but I don't want someone's car to blow up. I usually crank the boost and add timing rather than trying to run it leaner. IF you pull a bunch of fuel with the alky and something happens to the kit it is going to cost you an engine

and al said---
90% of the power from an alcohol kit comes from increased boost and cooling the air intake temps at the manifold. You can also increase the timing slightly but given the higher boost your cylinder pressure is already approaching optimal. Leaning out the a/f is going to add more power - but the increase is very slight and the risk is great.
Prudent tuners leave alcohol tunes rich.

warrtalon - dont say something u dont know for sure...

 

I didn't say anything I don't know for sure. You are quoting other people, and I am talking about what was done on my car right in front of my eyes. I do not run crazy boost. I run a moderate 26psi. I was in the 9s when the alky was activated, therefore, Al removed a ton of fuel. This does not mean we ran the car lean - only to the low 11s, but that's still a lot of fuel removed from 9s. We also ran more timing. I did not try to run 28-30psi, since this is a daily driven Evo that I use for road racing on the same tune.

You absolutely CANNOT RUN ALKY WITHOUT A RETUNE. You just aren't understanding how alky works and are taking comments out of context. No one adds alky and runs it without a retune - that makes no sense.

 

I'll try to answer all this.

1) I was around 300whp/300wtq on the 12.26@110, then around 335whp with the 12.0 runs, but I never dyno'd on that setting. That was just me adding race fuel and turning up the boost after running the 12.2 with the same mods. The trap speeds of 112-113 indicate 330-340whp on a Dynojet.

2) After adding the ported/coated manifold/10.5 along with SS O2 and alky, I put down 341whp/361wtq (93oct, no more race gas), but the tracks were closed before I moved from VA, so I didn't get to slap down some high 11s.

3) Alky and Meth are pretty much the same in terms of power - alky is just easier to get at more places than meth, but meth costs less

4) Yes, I run my alky 24/7 on the street, drag strip, and road course. It's illegal in SCCA, so I turn it off, add race gas, then plug in my SAFC with fuel added (I tuned it myself on a dyno to ensure safety without the alky).

5) For me, I have the SMC with 1-gallon tank hidden in the driver's side fender well (trunk). It lasts about 2 full tanks of gas of daily driving, so I refill it once every 2 weeks or so. On the road course, with the tune I have and smaller nozzle (7lph), I was able to do 20-25min sessions and only use about 1/3 of a tank...maybe 1/2 with no traffic. I did 7 sessions for a total of about 125-130mins of road racing and used 3-4 gallons of alky. I brought 4 cans but only used 3 plus whatever was already in the tank. I was very pleased by this.
