is it good for high compresion motors like 12.28?

 

like we have a choice

 

it's bad. High always better.

 

damn norcal is getting 92 again this winter..

 

I get 93 here in Alabama

 

Really???? When...getting tired of 91 octane

If you have someone properly program your ecu, and dependent upon which cams you have, you can run 91 octane. The tuner that I deal with has a couple of customers that are running on 13:1 with 91 octane.

man...anymore raising prices on gas i'm gonna die!

 

Wisconsin too

 

pushing it 12.1 , a good ecu program helps or even running hondata

 

I'm sure if you were exteremely worried about detonation while running high comression you would retard the timing as well, correct? Im not saying its necessary, but would definately help prevent it.

 

94 at Sunoco in PA

 

I hadn't heard this either... When? Where? Booya!

 

You said 13.1 damn but what kind of timing are they running? 11 degree's?

 

No clue...it's all handled inside the ecu...when you're reprogramming the ecu the distributor timing doesn't matter as much.

 

oooh where the 92 gonna be at? man theres that pic in like motortrend of a texas gas pump it was liek 120 for 93 octance..

 

Maybe SoCal will get it again too!

i always send my polar bear out to fill up the R w/ 94 from sunoco.......(I
m in Canada)

 

I know a guy who had a car with compression up in the 13's making ~250ish whp on 91 gas.

 

.....sucks, I get pissed when I have to put 92 in the car. Sunoco has 94 pump

 

Yea... that thread told me a whole lot of nuttin... other than one guy guessing that they're peeling the 91 sticker off... Hmmm....

Oh, and 76 doesn't use MTBE because they use methanol. 76 runs like crap in my car.

 

in some cars the MTBE free stuff gives better mileage though. I dind;t notice it in mine.. I usually use chevron

 

well if you are by redlands the texaco on the corner of Redlands BLVD and Tenesse sells VP racing fuel if you need that extra boost
