Water & Methanol injection (E85)
Any ideas on whether water/methanol/ethanol injection is effective enough to convert an NA engine to turbo without decompressing? I guess it will relate to comp ratio, fuel octane and boost so I'm talking about 10:1cr, 98oct and 14psi for arguments sake

Why not consider E85! there are lots of good sites that offer great info on converting to E85. It will handle much higher comp and run much much cooler.

Thanks for the tip. E85 looks like the way to go for budget turbo conversion then 20-30% more fuel required but can support boost to 14psi on engines with greater than 10:1 static CR.
Is a standard AFR meter going to work and would you be chasing similar figures or much lower given the greater fuel requirement?

AFR will be worse. It runs richer therefore less economical.
E85 loves moisture so so will have to change fuel lines and run a plastic fuel tank.
But its great for the world.

Sorry my question was poorly worded and is well answered here http://www.e85mustangs.com/tuning.html So using my Innovate LC-1 14.7 will still represent a Stoich mixture even though in reality the actual AFR will be 9.7 because it's measuring Lambda of 1.0 then converting it to AFR. Why the need for a plastic fuel tank? I understand the need for new non nat rubber fuel lines.

E85 attracts moisture. You can't really tell if the fuel has moisture(water) in it. Moisture rusts steel over time.

Mickas is correct. Any ethanol blend fuel is hygroscopic which means it attracts and absorbs moisture. It also has terrible 'shelf life' because the blend separates.
I will declare my hand on this topic as my company is the distributor of Sta-Bil fuel stabiliser so we have a fair bit of knowledge on the effects of ethanol.
In ethanols defence, in a daily driven car where the fuel is usually not in the tank for much more than a week it wont pose too many problems but if your car is just a toy that isnt used regularly then tread carefully.
If you do use E85 in a hobby car then you will be well advised to use a product like Sta-Bil as it will pretty much eliminate the bad points of ethanol.

Hey Gdub Im planning to use e85 in a track car does this sta-bil have any adverse effect on the fuel?

It wont adversely effect it in any way. It simply preserves it so it stays as it was when you bought the fuel.
It also protects it against moisture abosrbtion.

So is there an approximate figure on how long products such as sta-bil will extend the life of a tank of fuel beyond the norm? Is sta-bil widely available? Is e85 likely to become widely available in the near future?

I know we have it at Autobarn, and if your local one doesnt they can get it easily for you.

Yes... I think from my class memory the other day Caltex is behind it...

Sta-Bil will keep the fuel fresh for 12 months when used at the correct dosage which is 30ml for every 10 litres of fresh fuel. It is available at Autobarn, AutoPro, Super Cheap, Repco and Burson stores. E 85 will take a while longer to become mainstream but the latest commodore upgrade is setup to run on it.

iirc caltex is "flex fuel" ie, 70-85% ethanol. great for the commodores, not for someone looking to tune on e85 specifically
