I searched a lot but I didn't found any discusion about the AFR on meth injection.
I am running around 12.2 with good results but I would like to know any other members AFRs to compare with mine.

My results Stock IX turbo 30psi, Injen IC pipes, TBE and 50/50 AEM 1000cc
410whp
Timing goes around 7k is 19degree

Has anyone else more aggresive timing and AFR on meth?

I ran 12.5:1 on 100% methanol injection.

I figured run as lean as I could without knock, more timing caused knock in my case so I just kept leaning it out until I got to 12:5.... still had no knock.

GreeceS13

What timing are you running?
I have
6500 17
7000 18
7500+ 19

Wouldn't you benefit more from increase timing compared to leaner AFR's?

Edit: I just notice your timing is 19 up top. That's usually the most I have seen or heard of anyone running. Not bad results with the stock turbo

GreeceS13

Haha yes! And no knock...
I wish to know if I can run it a bit more aggresive..

How much boost are you holding up top and are you using a ecu control boost or MBC?

GreeceS13

Hybrid boost control..
Grimspeed + MBC
I am running 32psi peak boost but around 6000k is 26psi... and after that rpm less and less and less :/
I cannot find a way to keep boost at high rpms

The stock turbo will not hold much more up top one of the trade offs to being a great street turbo.

If you have pushed as much timing the car will take and leaned it out as much the car will allow without knock then you are at the max. But at times it's pretty to sway to a little conservative just in case

<p>Yes I think that I cannot do something more.. </p><p>And everything after that is expensive..</p><p>&nbsp;</p><p>I find in good price tomei arms turbo second hand..</p><p>And with a bigger intercooler will be my next upgrade but I don't know if its worth the tomei turbo!!</p><p>&nbsp;</p><p>I wish to find a fp red in good price but there isn't something here..</p><p>&nbsp;</p>

Fp red is a great turbo good all around setup. A BBK-B ball bearing turbo is a great option as well. It all depends on what you are trying to do. My next setup is going to be a red or BBK-B. With a FP cast manifold.

I think you would want to run a little rich at WOT uptop, no?
