What A/F ratio to aim for with a lot of meth?

[Slowrc]

Wondering what air/fuel ratio you guys are using for turbo applications with a good bit of meth? I am running 2 15GPH nozzles on an Alky-control kit.
THANKS!

I run two nozzles and a 200 psi pump, and shoot for low 11 afr's on the gas scale.

Good to hear. Had another guy answer the same so that makes me feel better. I am in the mid 10's now working on leaning her out. Thanks for sharing!

It depends on how your using the meth, lower IAT's. make more hp, more octane, etc. You really cant just shoot for X a/f ratio because there are too many variables IMO.

I am using an alky-control kit to spray 2 M15 nozzles. I use it for octane, cooling , and for more fuel.

Same, you should notice a power increase when you get it leaned out to the low 11s.

I have a progressive controller and have altered the boost VE table to allow for the Meth and find fueling very consistant

Yes sir. Last time at the track , the leaner I tuned it , the more mph. Just wanted to know what point others were shooting for. Answers through various forums have all said 10.9 -11.5. Sounds good ! Thanks for responding.

To rich will really hurt it. More then less timing. Just be careful how far you lean it out. You can go to 12.2 to 1 . You need to watch your plugs. Tune to leanest cylinder. As long as it is well atomized before it gets to the intake manifold you will be right. 11.5 to 1 is good. Any richer will hurt it.

When shooting 30 Gph straight meth, wouldn't you want it richer than the normal mid to high 11's for air/fuel ratio ??? My meth is not just for cooling. It takes a good deal of fuel map remaoval to run this much meth. Thanks for input guys.
