putting the Wagon on methanol

Been running my Dart and my Volare wagon on E85 the last two years.

Won the track championship last year using both cars, so I cant say anything negative about E85. Its been good to me, and I plan to still run it on the Dart.

I had an 830cfm E85 carb on the wagon. When I bought the car it was running 7.40's. Through tuning and going to E85, its best pass to date is 6.95, and normally goes low 7.0's.

Now I have a 750cfm Methanol carb that I just had built. Will be this coming friday before I'm able to go to the track with it. I'm guessing once the tune is finally reached it should go mid 6.70's to mid 6.80's range.

What do you guys familiar with methanol use for a top lube, and how much per 5 gallons?
Any tips on maintaining the system from corrosion?

I have the following parts or have done the following:

Methanol fuel pump and a meth bypass regulator with a return line to the fuel cell.
Have taken the foam out of the fuel cell.
Have a 10an line feeding the pump and 8an the rest of the way.
have a lean out valve installed for helping get the engine up to temp.
will get the engine up to 185degrees and spray wd40 in the carb before shutting off the engine for the day.

Thinking of installing an oil temp gauge and an oil pan heater to help with cold starts on cool days.

Anything else?
