Dual fuel tank setup for pump gas and race gas
 

Ive been brainstorming about how to do a dual tank setup to have a pump gas tune setup for daily driving and then be able to switch to a race gas tune with just the flip of a switch.

I have a buddy that runs something similar on his bmw m3. He has a stock tank running pump gas and a 5gal tank with race fuel. He has a toggle switch that when activated the race gas is injected thru nos nozzles thru the intake manifold into each cylinder. So at the flip of a switch he has a higher octane fuel and can boost higher with more aggressive timing. Also the system flows both pump gas and race gas at the same time.

Im asking because i have a few things that keep me from doing either or. I wanted to switch to E85 and be done, but we have 1 station in charlotte where i live and that isnt gonna cut it. Then people say buy a drum of the stuff and just go from there. Well i live in nc and i drive my car daily and far. Mountain trips are always a tank of gas away. And race gas is too expensive to run on a daily basis.

Ok, again i drive my car a lot and i have people i wanna spank as well as bikes that i wanna beat. And i hate saying im not ready, or i dont have any race gas in my tank. Also hate draining the tank just to do that. So is there any way to have the best of both worlds under one hood.
I run 93 pump gas and boost juice (meth). I did 550/500@23psi.

What you guys think.

It's not very hard to do. there are a few guys on the supra forum that do it.
