"Lead" Fuel Additives?
I'm interested in any information about fuel additives that *really* improve octane. For those of you who do not live in the USA, my best local "premium" gasoline is unleaded 92 octane(RON-method).
I've done a "Google-search" and have found lots of claims for products. I've looked through some of the older posts here. I've talked to race friends, a chemist (he owns a Cobra)and the guys at the local speed shop.
I hear lots of unproven claims by the companies selling the stuff, but I'm leary of this (snake oil?).
Some of the products talk about extending valve-seat life and cleaning the fuel system...I don't care about these features. I'm really only interested in preventing knocking under acceleration.
My car isn't an extreme example of "race tech" but it will be used for sprint and enduro races: this Winter I replaced the old 7.3:1 compression pistons with 9:1, milled the head and replaced the cam with a modest performance unit. I'd like to run 32 degrees of total ingition advance.
I don't think I really need to start buying Klotz or CAM2 in 50 gallons barrels yet. Many tracks sell high-octane race fuel, but not all of them, and anyway, I'm still going to drive this on the street once in a while.
Right now I'm looking at the Klotz fuel additive, mostly because their other products are decent. Any other advice?
While I'm at it, has anyone seen any real good information about the use of aviation fuel in cars? I hear all kinds of plus/minus stuff about this.
