I know they never said it would make more power, I'm just saying that if it did then it would be AWESOME.

 

Hi all, first post but have been lurking here for awhile. (c/o picked up in October)

I have read a lot of these track key threads, I wonder why with 91 octane being required there is not any gain in power? I would think a couple horsepower could be gained just by tuning a car to run on higher octane fuel. Thanks, Keith

 

Does anyone know high octane TK will adjust to? Will it go to 103 for aviation fuel?

 

Stop, your making way to much sense!!
Only problem is none of the dyno test really show any HP gain. At least Ford did not mislead us on that. I for one realy wanted that true Loppey ideal. Each one of us has different uses for TK. I dont track my car as of now. I just enjoy driving it to shows and realiving STRESS. It works soooooo well on STRESS.

 

It's rumored to be 100 octane but there won't be any significant HP gains. Maybe 5 running 100 octane. Probably not worth the added cost. But if you have a K&N filter with the side pipes wide open and aftermarket axelbacks you could probably pick up 10 HP.

 

I did not see any dyno gains running 100 octane. The standard deviation of the 100 octane runs was more consistent, however.

I'd run it if you want that extra peace of mind, but outside of that, you're just paying 2x the cost of fuel.

 

~$6/gallon. Bought some for a friend's plane Saturday and that gave me the TK idea.
Thanks for the info guys.

 

The reciprocating engine aviation fuel most prevalent at today’s airports is 100LL fuel dyed blue in color. The older higher lead content 100/130 (lean/rich) octane gasoline dyed green is practically nonexistent in North America. Thus if you go to a local airport and inquire about “103” octane fuel, they will most likely not have a clue what you are talking about. Both these aviation grade fuels contain tetra ethyl lead which will quickly fowl a catalyc converter equipped automotive engine.

Just understand that the octane rating ascribed to an aviation gasoline (manufactured to ASTM D910 specification) is not the same as the “motor” or “research” octane branded to an automotive produced gasoline (manufactured to ASTM D4814-11a). The two are quite different.

 

The only aviation fuel I would put into my vehicles is JP8/Jet A, and it would go into my powerstroke. Even then, it still doesnt lube the walls as diesel would.
