VP octanium fuel additive

[biholliday]

i recently purchased this can of additive to 10 gallons of 91 octane and was able to add 3 degrees of timing to my high octane table. the difference was very noticeable. i probably could go another degree with no knock. it costs 28 dollars on ebay. i watched a you tube video where the tuner gained 70 hp on a ls7 just by adding 1 can

I've used it in the pass on an older set of heads (12.6:1). The local Autozone carries it. Only thing I didn't like was the deposits it left on the spark plugs, its like a red/orange layer that builds up over time.

I remember when we used to make our own. 55 gal drum with pump premium, AVgas, and Toluene. Came out to around 115 octane. Most likely the reason I have problems finding my keys over the last 10 years.
