Ok. Last time out at the track(1/8th mile) i was trapping consistant 90-91mph. This was on 2 gal c16 mixed with 2 gal 93.

NOW, i have since added an alky kit(along with V3). I went last night and could not trap more than 88mph for the life of me. I have not tuned the car on the alky, i basically just ran my same map i ran on the race gas mix, but instead of race gas, i used alky.

I tinkered with the maps last night in between runs, but couldn't manage to gain any MPH. YOu guys that added alky, did you have to pull a large amount a fuel out when you were spraying alky?

Im guessing a couple things here: Either the car was knocking and pulling timing running this map, OR the car couldn't burn all the fuel+alky efficiently.

What do you guys think? Any help would be appreciated!

BTW, for the last 2 pulls i dumped ~3 gals of 110 in with my ~5 gals of 93....nothing changed! So im thinking it wasn't pulling timing badly.

 

u ran a 50/50 mix?

 

I didnt know race gas map is the same as alky map. I thought it was a differnt kind of tune Is this true?

 

strait alky

 

you do have to remove fuel with the akly....i don't know how much...but it does compensate for fuel......

 

yeah, i figured that....but some tuners say not to remove much, and some day do.

i removed some fuel, it didn't make much a difference. it was pretty consistant on 88mph, thats what makes me think timing was being pulled....no matter what i did, same MPH

 

I'm running 50/50 mix Methanol/Distilled water. I'm runnig 15% alc/h20 to fuel. My AFR are 11.7:1 richening up to 11.2:1 by redline. I also added timing up top, max 21degs. Stcok turbo 26psi, tappering to 22psi by 8Krpms.
You could be drowning out. Lean out, add timing, gap plugs to .024, crank boost.

 

boost is cranked. I guess i just need to make a freakin 5hr trip to the dyno. I have my timing map zeroed out on my xede, which is a few degrees advanced over stock due to the MAF manipulation.

maybe i should just lean the ***** out on lower boost and listen for knock....and add boost till im to the sweet spot.

Thanks for the input bishiboy.

 

Running the same map for race gas as alchy isn't a good idea. You can't advance timing as much with alchy as you can with race gas. If I was a betting man, I'd bet that you were pulling timing.

 

its amazing to me how many different opinions there are on that particular matter. Some people say you can run the same amount of timing on alky/pump as race gas, some say you can't.

 

lol....the situation you have now is like asking a bunch of blind men to describe an elephant...one will say it feels like a hose, another, like a tree trunk.........

Data log and you will know what the hell is going on!

 

well, to be honest, i was hoping for tuner's advice. you know, the guys that have actually tuned an alky kit.

i know how to weed out the, "i heard you can't do this" type answers/people.

But, ive spoken with 2 tuners so far who say im running SOOOPER rich. And the same boost and timing levels should be fine from race gas to pump+alky.

 

This is your problem. There is no mystery otherwise.

 

well, i know that much, LOL. I just wanted to know some things to step in the right direction of running the best tune i can.

Ted, any chance i can take a look at your 93 octane map VS your 93+alky map? I jsut want a comparison between your 2 maps to see how much fuel is pulled when you are spraying alky. Im not going to run these maps, i just want to know how many points of fuel are pulled from your 93 map to your alky map. Just for comparo sake.
