Who sprays the most ALKY and what is your target A/F?

[Scott Atk]

I have mine set on 6 with dual nozzles. 100 octane. 27 lbs of boost. A/F ration is 10.5. Sure is a blast on the street. I've never had as much fun as I have been having lately.

Thats abput right..

Glad to hear you out playing again..

[Scott Atk]

ttt... I was hoping some of the heavy hitters would share what setting they are using and what's their target A/F ratio, also do they alter their A/F ratio in the lower gears.

 

[PaCemkr86]

i set my target a/f without the alky @ 11.3-11.5
then crank the alky up till the knock is gone.. and then keep going up till its not happy then back it off.

usally end up around 10.0 -10.5 a/f..


im not a heavy hitter though.. LOL





not yet anyway

Sissy.......


Put 93 in there Scotty and be a man will ya...

We run with Julio's kit using dual nozzles and the controller on th max setting. Target is about 10.3-10.5 at 25 psi with about 24-26 degrees of timing.Many cars set up this way with excellent results!

Are you using the R chip and what's the timing?

 

[Scott Atk]

Yes on the "R" chip... 25 degrees timing.
Sounds like I'm in the ballpark. Im down some ET and MPH from my old setup and thought maybe I should go back to 11.1 or so.... Now I'm not so sure.

Forgot to ask but is your R chip/ECM set up for the WB control?
PS: What is the new mph/et compared to the old?

That timing is outrageous! How are you pulling that off? What octane of fuel are you running?

93 octane.. what else

Hey Julio, how is everything going? I was curious how you know when it is time to make the jump to the second nozzle? Should I call you for this answer?

Thanks,

Shane

One thing to look at is air fuel as your going down the track. If the air fuel starts to drop the further your in it.. your shooting way too much methanol. I'll see if I can get some datalogs to show this up. Richie's car was spraying way too much.. and his injector duty cycle was constant.. yet the air fuel would drop past the 1000 ft mark.. Turned the gain down a tad.. badabing.. cleaned it up. Last night he ran 9.59 again at 140.xx off the foot brake.

we run the pump at 100% and trim the fuel back, straight racing methanol and 93 octane. You MUST run the a/f a considerable amount more rich with methanol than you would on racing fuel. We use the methanol as a fuel, the cooling benefits are a bonus!It takes alot of dyno time and some creative FAST tuning before you master it.

So I am assuming I will never pull that off with a factory ECM. That is very impressive. One day I will get there.

Thanks for the feedback!

nothing wrong with the stock ecm .

easier to fine tune the fueling with aftermarket like FAST but not impossible on the stock ecm
with a good chip to get it close and gather data then have it reburned based on that data to be that much closer

we also have other fueling adjustment methods available on stock ecm like the maf pro and mer wideband adjustable setup

Im on TT wideband control and stock ecm

Julio, I would love to see that data. I'm assuming Richie has the same ALKY setup as I do. What setting are you guys at?? Lower than 6?? I've been pulling lots of fuel and still running pretty rich (10.5 - 10.7) and was planning on pulling out some ALKY next. I know I'm being conservative with the A/F ... but Russ is right, I am a sissy. At least until the motor is paid off. I would hate to break it while Im still making payments on it. :smile:

That is reassuring. I will have to keep after it and see if I can push the limits.

Same everything.. I would say his is about 6 rite now. It was cranked all the way..

He ran 9.5 at 10.5 afr so no worries.
