Tuning meth injection question

JTs03v6 · April 5th, 2010, 10:50 PM

Think I'm going to run a 50/50mix instead of 100%meth so I can step the nozzle up to a 6 or 7g. I dont want to take out any fuel but will if I have to.

What should the stoich point or a/f I should tune for under wot?? Would 11to1 be good??

Yes 11:1 would be good. Post up the graph.

Have been doing some street tuning for now. a/f stays around 11.3 with the 6g nozzle and 50/50.

I know all setups are different...but what is your a/f with the meth?? what size nozzle??

I dont know the size of my nozzles. In 08 the a/f was 12:1 spraying straight meth. I'm running E85 and only plan to spray what ever washer fluid is. My a/f is set at 11:1 right now.
