We did some testing on optimax with our land speed record bikes and found no gains with it and infact found looses even after ign and squish etc had been altered to try and make use of it.

The BP Ultimate worked much better even when simple back to back runs were performed.

Of course every engine is different so in some cases it may well be that optimax is better than your standard fuel but in these cases it wasn't
