Guys
Thanks for the info. I have both a Knock sensor and EGT gauge on the GN as when you have a turbo motor you need to keep track of what is going on with the EGT and Detonation. However, on the normally aspirated Cobra I don't have any of that. The Cobra is 11.5 to 1 compression and I have had no problems with it as I run my Toulene/Xylene mix at 10-15% and it works fine. At the races I put in 116 octane on top of my "mixed" fuel and eliminates the problems.
Re the Alcohol setup on the Buick it isn't an Edelbrock setup and its made specifically for the GN. I've been thinking about getting an alcohol setup for the Cobra so I can simply put 93 octane in the tank and forget about mixing. Still up in the air about doing it though. How did you like the Edelbrock setup?
Regards,
