Another methanol-fueled 7 is born!
Much thanks to Howard Coleman for his help and for the pics & documentation on his installation! Last Thursday I finished installing my AlkyControl kit, which I had purchased in December of last year but never got around to installing thanks to my workload and the fact that I had to figure out how much line I needed. I had to mock everything up first and send the line lengths to Julio @ AlkyControl, and he got me the lines a day earlier than he said! Awesome guy and great product!
Anyways now to the setup. '93 FD, 100% methanol, coming on at 12 psi. I'm running the M15 nozzle, about a foot-and-a-half from the TB elbow. I haven't calc'd out the exact ratio of meth to gas, but I've got the dial set at 6 and took out quite a bit of fuel. I'll figure it out from looking at the datalogs I've took and post back if anyone wants the exact figure.
So far I'm running 24 psi with 91 octane pump gas and the methanol. This is on a half-bridgeport 13B-REW, with a Turbonetics T-66 1.0 A/R & Rotary Extreme monster v-mount. Haltech E6K, with two MSD LS1 Blaster coils for leading and stock LS1 coils for trailing, B10EGV plugs with stock gap.
With the testing I've done so far, I've gone through 2 gallons of methanol. Our shop was helping out with a drift event at Willow Springs so I decided to run the car out there, to test part throttle boost. The car ran flawlessly, although at one point we were worried about a methanol leak. It turned out to be condensation on the intake pipe, not fuel.
I wish I would have done this sooner! The power is smooth and the car is the fastest its ever been! There's more work to be done with tuning, but so far the setup is great. One thing I need to do before my next track outing is find some foam for my fuel cell, to keep the meth from sloshing around. With a full tank it didn't seem to be a problem at the track, but that doesn't seem the ideal solution for that. Anyone have any suggestions where I can find the foam?

congratulations!
24 psi w 91 pump and alcohol. and i bet your knock is close to non-existent.
as to foam... if you search fuel cell vendors it is easy to find. my 4 gal Jaz cell came w it and it is a necessity. BTW, there is such a thing as methanol safe foam. i discussed this w Julio and it was his opinion it was not needed.
i have run my foam for a year and removed it recently to check and it is perfect.
do keep us informed as i am sure many are interested in your results and setup.

Heh, heh, very cool. The single M15 will run out of steam in the low-mid 400rwhp range so you may want to consider upgrading to a pair of M10's with a tee.

the rotary requires 1.3 times the air and gas to make the same hp as a piston engine.
Julio is giving you piston numbers. so, 550/1.3= 423. you need two M10s. that's 1200 CC/Min.
i find that you want to displace as much gas as possible when you are at max boost....
i am shortly going to 1600 CC.

This is assuming a pretty gross replacement of fuel with alcohol. I normally do 70% gasoline and 30% alcohol. Obviously, if the amount of alcohol used as a replacement for gasoline is very small (5 or 10%), then the capability of that single M15 will be higher.

Edit: Forgot to add info about gas/alcohol ratio

i suggest you purchase a Y fitting.... jegs/summit and replace the T fitting that will come from Julio. the Y is from NOS and is anodised aluminum. aluminum can over time be degraded from meth but perhaps because it is anodised mine is fine after a year of usage. much better flow w it.
