Calif 91 octane woes

[Chris Thorne]

Just wondering how those of you who are
here in CA, the (tarnished) Golden State,
are dealing with the stepdown in octane.

For those of you who aren't here: starting
around July, 92 octane premium disappeared
from our pumps. The highest you can find now
is 91. Dishwater 91. My GSR rattles like a
castanet with the stuff and it's not running
a turbo or S/C!

From the (patronizing, self-serving, dumb,
dishonest) Tosco press release, we have this:

"Is 91 octane adequate for high performance vehicles?

Tosco anticipates 91 octane gasoline should meet the needs of almost all premium 76 gasoline customers."

Yeah, right.

Guess they don't deal with many customers
on forced induction. The last blown car I
drove needed 93 -minimum- to keep from
melting its piston tops.

My experience has been that most octane
boosters sold OTC are pretty much expensive
junk. Plus they are usually MMT these days.
Nasty stuff.

Chris

For anybody who lives in the bay area, there's a 76 station on almaden that sells 100 octane at the pump. I believe it's about $4.00 or so for a gallon.

Directions:
Take 87s to Capitol expressway. Make a right on Capitol Expwy. Take Capitol to Almaden Expwy. Make right on Almaden Expwy. 76 will be on your right.

Damn it's good to be in a non-nazi state where I can go to Sunoco and fill up on 94 octane at the pump for $2 a gallon or less.

Y'all need to move out of california! Then while they try to figure out why their tax revenues are dropping, you can be running with advanced timing on your blown 'teg, AND eat a burger in a restaurant cooked RARE, while SMOKING at the bar!

Cheers,
Ben

I hear ya brotha!

With 91 octane my J&S lights up 2 once in a while. 104 and other cheaper boosters did nothing for the detonation. I used NOS racing formula and the J&S hasn't lit up. Highly recommended but at $10 a pop.

Just FYI there is a 76 in South Pasadena that also sells 100 octane. It's at the very end of the 110 north. Can't miss it.

I know what I would do if I lived in your land of earthquakes, fires, mud slides, riots and low octane. I would definately be running a good quality octane booster and be done with it. Nos is a good brand as well as many other. So relax and BOOST! Octane boost that is.

OK, this thread seems on topic to this so I'll finally ask. I haven't noticed any difference with the 91 octane and wouldn't think anyone would that could run at 92 without a problem, unless you're running right at the edge .

That said, I tried some octane boost, including when I had my car dynoed, but noticed (what a surprise ) that my car was running extremely rich (i.e. 11:1 even down to 10:1 at top end when I was running about 12.5 to 1 without octane boost). Now, I'm not the most technically inclined here, but usually overly rich=less power. The other thing I noticed is that even though it was rich, it did not allow me to run any less timing retard on my BTC or affect my part throttle detonation under load problem.

So, my question to the more technically inclined is if you run octane boost all the time, wouldn't you also have to modify the car's setup in terms of fuel pressure, timing, etc. for it to have a positive effect? Or do I have some other problem I haven't figured out?

With as much as these robs charge us for gas (have you noticed 91 is about as expensive as 92), $10 of NOS octane boost isn't bad. I was paying $2.00+ per gallon anyhow so it doesn't seem too bad.

Regardless I'd like to thank the jerkoffs who decided it would help the environment to have 91 octane.

It also pisses me off that they charge us more claiming it takes longer to get gas to us when in other parts of the country pay less yet they have gasoline shipped from much farther areas.

From the info I've gathered and conversations I've had, 1 octane point is usually good for roughly 2 degrees of timing as a general rule.

On my car, retarding the timing by 2 degrees in the midrange resulted in a roughly 5whp loss in that region. In the dyno graph below, at 4000 rpm, the green line is retarded a max of 2 deg from 2500 to 5000. The blue and red lines have no retard in that region.

Yes, it definitely sucks ass.

I got my MAP and BTC installed just in time apparently (before the last of the 92 pumps disappeared). The MAP will definitely help those poor CA JRSC 'teg drivers. No pings here. My BTC is probably dialed in more than it used to be also . . . bastards!
