It’s hard to believe CR but it’s so true. Someone please help me understand how gas prices can be cheaper in other states then Texas? Although I think we are still at $2.90 for 87 and $3.10 for 93.

 

How about 3.19 for 87 octane right up the street from me.

 

There is a station just down the road from Watkins Glen International that sells race gas for $6.21 is the last price I saw the other day... I wonder if a stock bottom end would stand up to race gas? Or is my idea of the performance of race gas way off?

And I thought $3.09 was bad for 87 less than 1/10 mile from my house. I live 10 minutes from the PA border where gas is usually $.10 cheaper.

 

the 94 octane i refered to here is sold at same price as the 93, also I'm in vancouver and there is alot of olympic construction goign on so sometimes access to gas stations are blocked off and they offer premium at regular price

 

Race gas is just very high octane, it is not rocket fuel or anything. Without proper tuning it will probably make your engine run like junk, actually. It is also probably leaded, which will do a real number on your catalytic converter and spark plugs.

Even with the proper tuning it will not make much more power than 93 octane in a N/A engine, at least not one that was built and designed for 87. The compression just is not there. The more octane you run, the higher compression you can have which = more power. More compression = power, but you need higher octane to run the compression without detonation (spark knock, which is bad)

I used to drag race a 75 Mustang Chassis car with a 600CID Big Block. It used 116 octane race fuel, and had about 13.5:1 compression (if I recall right). Our engines have 9.8:1?? compression . If we had used 87 in the race engine it would have probably melted a few pistons.

 

You're thinking of 100LL (Low Lead) Avation gas... "Sunoco 260 GT 100 is designed for high performance street cars, muscle cars, classics, street rods, motorcycles, karts and marine applications. Sunoco 260 GT 100 contains no metallic compounds to harm catalytic converters or oxygen sensors. It contains a comprehensive additive package for greater engine protection and reduced fuel system deposits. Sunoco 260 GT 100 is also compatible with virtually all two-stroke synthetic and mineral based motor oils."

It's available only in Guntersville, Alabama... So like I could drive there... Load up with gas and Dougs new 100 Race tune drive back home and fill and dump the 93 Race back in!

But it would be a heck of a ride back home!

 

Opps gas prices are falling here in Houston, went to the station and 87 is $2.74 now and 93 is $2.94. Lower is always better right...............
