Default pump and injectors for straight Methanol

What’s up guys been thinking of changing fuel set up I am currently running c16 for fuel but been thinking of going straight methanol. Just been doing some research and wanted to see what is the fuel pump n injectors size to go with. Car is a Twin 66mm turbos forged LS 6.0. So to make the questions short is what fuel pump n injectors should I run? Thanks in advance fellas

What are you running now? Figure the usage rate of meth compared to the present fuel and go from there

The pump shown in this picture is one of their best and can handle the methanol but it will set you back about $1400.00.

I am making the leap. Next week on the dyno. I will let you know. I am 120s and magnafuel 750 pro tuner pump. But n/a first to get a base line. If I got room I will add a little juice on a dry shot. I am shooting for 600 to the tire n/a.
I am curious how far 120s on methanol can go. N/A ,juiced or, forced induction.

It's been said to stay away from aluminum when dealing with methanol so its PTFE and/or stainless steel hard lines, stainless steel or plastic tanks yet the fittings and fuel rails are mostly aluminum. What's been your experience with using methanol and aluminum rails and fittings? Do they just need to be changed out more often?. I take it an E85 compatible aluminum fuel cell would be a no go with methanol or would it be okay as long as your purging out the fuel system after use.

That greatly depends on what the duty cycle is currently.

I've not messed with M1, but from what I've read it takes a ridiculous amount more than gas. E85 takes about 30% more and I believe M1 takes even more than that.

After every race my friend did in his sprint car he would have to purge the methanol from the system and give it the ole Marvel's Mystery oil injection.

Well initial start up went good no issues. I added 30% to the fuel map (was on e before) changed tune to methanol.Idles better than ever at 5.5 afr.
To get me to start up point. Change filters pre and post pump to stainless mesh. Put in ntk o2 sensor and changed the tune.
I'm all ptfe and plastic cell, anodized everything. I dont plan on flushing it out till race season is over. Efi is completely sealed so dont really see any way oxygen can get into the system to oxidize.
Goes on the rollers Thursday. So far been an easy transition.

It's when the methanol is flowing that it can start eating away at anodized aluminum fittings so keep an eye on them.

Well good news is 120s are 80% DC at 550 rwhp at 40 psi. Over 750 pounds per hour. 58 psi same hp 650 pounds per hour. 100 shot of the juice netted 660 hp. Required 90 pounds of enrichment. Ran out of time for a 200 shot. Need to go over logs to make sure I have room for another 100 hp.
I would say out of all this you better get a huge pump to run over 750 hp. My pump was rated to 2000 hp on gas and I would be scared to push it to half that on methanol.

Keep in mind that the problem with methanol is that it carries its own oxygen. Corrosion can and will occur in a completely sealed environment.
