Help, I'm stumped!

Update; After conversations with my local shop, visiting with Keith (Keith Craft), Quick Fuel and checking out your suggestions I'm going to install a seperate heat shield and 1/2" phenolic spacer. After a quick study I would really like a "Super Sucker" but they seem to be most effective from 1 1/2" and above and I don't have the space. The science behind these spacers is fascinating and the applications are specific to your driving goals. I'll be curious as to the effectiveness of this approach vs. a "Turkey pan."

I had similar vapor lock and fuel bowl flooding after I got gas in Austin coming back from our cruise to the OASIS on Lake Travis. I have no room to put a spacer but Keith and Rob recommended putting some 107 or 110 in it so I put 5 gallons of 107 in last Saturday. Took it to Cars and Coffee and then the Cobra lunch and it ran great and it was 86 that afternoon and no problems. I plan to mix about 4 or 5 gallons of 107 with each fill up of 93 for a while. Heck it was only $ 6.23 gallon so not to far from 93.....

Gary, where did you get the high octane gas in Dallas? Thanks.

High Performance World (HPW) at 3133 National Circle - Garland, Texas www.hpwtx.com 972-271-3900. It's a speed shop run by Husband and wife from Austrailia. They opened a couple years ago and have all kinds of performance parts in stock plus fuel. You can buy 55 gallon drums or take you container in and buy it by the gallon. I was going to get some 110 and after talking to him regarding my 10.7 compression he suggested 107 would be better as it burns faster than the 110. 110 is better for higher compression.

I haven't had the pleasure of buying 100+ octane fuel so I really don't know much about it. I have a sneaky suspicion that many blends over 100+ octane have some kind of oxygenate like ethanol or some other alcohol. You might inquire about the components in the fuel. The octane of ethanol is 115+.

Update;

I've just returned from a month out of the country and took my BDR out for my first run since San Marcos. I went North and found some great roads but still had some San Marcos fuel in the tank and after she warmed up the fuel 'starvation" issue reared it's ugly head again. I found a auto parts store and bought a bottle of Lucas Fuel Additive and filled up with some Shell 93. The combination was pure magic! The krap they called fuel in San Marcos was the issue. However since our government is going to continue to push corn as fuel I'm still going to install a phenolic spacer and keep a bottle of Lucas in my trunk .
