Have reported my findings on E85, E98, C85 & ftw 120+Purple to mark who will make the final call. The Purple appears the fuel of choice amongst those seeking big horsepower. I see Andy uses it in his Scoob. Very little in stock in the UK but ive tracked some down. Its £33 a gallon so not as bad as I expected. In various test just changing the fuel & not making adjustments its making gains of 10% over the others listed. Anyone heard anything bad about this Fuel. If Mark agrees I will buy 20 gallons of the stuff for Dyno development for mine & an EVO also striving for 1000bhp.
