Hi all, apologies in advance because I did origionally post this topic in the tech section...
I'm fortunate to live 10 mins away from one of the few morrisons pumps in the uk currently selling bioethanol. As you may know this stuff has a stupidly high octane rating of about 107 (it's also a greener fuel some say, although production has a big carbon footprint). Some cheap unleaded fuels already contain 5% bio to make them cheaper etc, the vw handbook suggests that there engines are perfectly safe to run on a 5% mix.
I can't take credit for this because it was actually beddies find but here's the idea..
Currently the bio on sale is 85% bioethanol 15% petrol, I think 106 ron. So with some clever mathmatics I work out a mix ratio that is equal to 85% petrol (vpower 99 ron), and 15% bioethanol (factoring in that it's already only 85% pure) giving me a fuel with a guessed ron factor between 101-105 whilst still keeping the mixture to engine friendly levels.
I know that a lot of people on scooby.net are actually having remaps written for this.
I'm doing a track day on Saturday and this could be a perfect easy increase of bhp, but I'm also aware this if done wrong could be fatal, I know a bloke who worked on the new bently engine and getting it to run on bio meant pretty much a brand new engine design.
I'd love any ideas, thoughts, experience, advice on this one guys do please let me know your thoughts on my "moonshine".
Oh and failing that, does anyone use the nos 7 point octane boost from halfords (not road legal and £20 per full tank)
