Rick in Colorado

I've researched a few URLs on this topic (see attached) - has anyone on the board tried this? I've also called around here in Colorado regarding prices. The gallons seem to average $9-10 and 5 gallon containers are ~$35. The premise is economically interesting at $3/gallon (as referenced in the articles), but at $10/gallon the use of pump 100 octane is at least as good (if not cheaper). Thoughts???

I have no experience with it. But I know that some of the guys on the 944 Turbo & S board use it. If you get no answers here, perhaps give that board a try.

Only experience I've had is that I used to put benzene in my Dodge 340 engine. However, I never ran it on straight benzene.

Rick - If you're asking about octane boosters for a stock 996 (and not a turbo), you don't need anything more than 91 in Colorado. The high altitude here makes the effective compression ratio lower and high octane unnecessary. There is, however, a place in Denver that I occasionally go to with 101 octane racing fuel for $2.99/gallon when I turn the boost up on my 944 Turbo S racecar.

Rick, Ive used it in my 996TT. I have put about 6 tanks through, 4.5 gal of Toluene in a 15 gal tank of 93 octane. Noticed no problems and it really runs as well as the VP racing 104 (which smells exactly like toluene). Faster throttle response is the most noticeable.

Regardless of what you use be very carefull of all of these as they are major carcinogens from what I understand. So this advice is like the saying...."Don't get any on you!" (I think inhale is also very bad for you.

GrantG is correct. I live at 8,000' The attached URL indicates that the effective octane at my elevation is 95 (91+8000/3000*1.5). I used 1.5 as an average of "1-2 octane per 3,000 feet". Even "down" in Denver the calc works out to 93.5 octane. Thanks Grant.
