Make sure its unleaded and you should be fine.. You wont have to worry about detonation.
I have some 108 octane (unleaded) in the garage, and some Nutec, there is no octane rating on the Nutec, but its $250 for the 15 gallon drum. I have not put either in the porsche, and probably won't... Probably.... heh heh...
The Nutec does contain lead.
Some intereting engineering facts about the bikes we race.. 600cc with exhaust, filter, remapped injection, and Nutec results in about 109hp at rear wheel, redline is 14,500. Thats a stock motor, with a few tricks you can get around 115hp
600ccc !!
