E85 vs M5 methanol for the compound build
Ok, I need other people's opinions.
Personally, I never used E85 or M5 methanol on any of my cars.
I've only used race gas.
On my current compound turbo build, I'll be using the stock tank, with a secondary fuel cell.
We are still deliberating if we'll use E85 or M5
I was thinking of just using regular gas 93 octane on the tank for DI injectors..........and M5 methanol on secondary fuel cell/port injectors
instead of E85 on both DI and PI.
what are your thoughts guys?
thanks!

LOL, your build is not a normal build. That I would talk to master gurus of the LNF world...
I would do e85 DI, and probably just some ms109 or something in the PI. What is this intended for though? I'm sure your setup isn't a DD and you want something for power?

Even with cam lobe upgrade, and 5th injector setup, E85 really isn't going to be realistic with those power goals with the lnf fuel system imo. It just can't keep up the flow demands. I would personally stick with race fuel and a good dose of meth injection.
Edit: I just rechecked your build thread. I actually didn't realize you're using a full pi fuel system in conjunction with the di system, although I probably should have assumed so with that much power.. lol
What size injectors are you planning on using on the pi system and what standalone controller?

The problem is I doubt this is ever going to be a DD with 800 hp LOL. I'm guessing he wants the best mixture of gas. I'm not too sure. All I know is don't put race gas and meth they don't work well together AFAIK. I remember some guy in the e46 m3 with a huge turbo was testing it out. His name is Tazaa m3. You can read about it if you google his name and active autowerk. He has a 1000whp m3. He would have some good info one what fuel to run in those threads..

I have my Nissan Leaf to daily drive so I can save gas and be earth friendly 
I would like to drive the car on the weekends, and run at the track once to see how she performs. It will be the last run since I know they will ban me from it after they already warned me before. Especially now that my convertible will probably run way faster
Unfortunately for a convertible, if u run 13.49 or faster, they require a roll cage.
Would like to join some HPDE if possible
Most 800hp vehicles with a single big turbo is not streetable since you really don't enjoy the power until it fully boost at high rpm. That big huge surge of power will kick in, and might be unsafe on the streets. Some set ups have horrible idle, overheats , and others have race clutches that's very hard to use on stop and go traffic
with a compound, I don't have to be on high rpm. Plus no huge surge of power.
I can easily enjoy the instant response of the gt28 and zip thru traffic (I'm assuming) .
Hopefully, I won't have those other issues. I have stage 3+ spec clutch, which I've used before . Feels like stock.
But who knows, the car might not be steerable? I never driven a set up like this.
About the use of race gas, of course I'm always open to it. But if I can use e85, with similar result, why not? Way cheaper !!!
Never used M5 methanol before, and wondering what benefits it will bring.

I'm thinking I'll just go all out e85 (both on DI and PI systems).
both the fuel systems were already designed to be E85 compatible, plus the ethanol is cheaper than a race gas or methanol..............and will probably produce the same/similar whp results (e85 vs meth vs race gas).
its a win win situation........power wise and price wise.
plus when I used methanol before...........it is just soooo corrosive. It corrodes anything it sees. Aluminum will just deteriorate so fast.
I think I can deal with the cons of e85 (maintenance, cold starts, availability, etc)
