When I looked at using methonal (I even ordered 25 ltres but did not pick it up and sold it to Justin)
In the water injection system I fitted to my Supra the health warning put me off.
Now I am no square when it comes to don't do that its dangerous BUT this stuff, if you spash it in your eyes it can blind you. The vapour from it alone is extreamly dangerous.
If you have got kids then the risk to there health is high.
I IMHO don't beleive the health risk is worth ignoring from what is prob very little gain in Power.
Just buy some bigger turbos, I advise the ones that allowed Christian to reach in excess of 20mph faster then my 355 over the same distance.
P.S. I did explain the health risk to Justin but he bought it anyway.
