I was having problems with my gas carb and a friend offered his alky carb for a try. My experiences were very positive. I run a Magnafuel fuel system, so it is compatible with both fuels, so all I did was drain the gas and put in alky and turn up the fuel pressure. The car definitely had better throttle response, more power, and ran extremely cool. Also ran really clean. Never got a track number out of it because it was after the season. I will be trying that same carburetor in comparison to my new 1050 HP gas dominator and see what the differences are. The only bad thing about the alky is getting it fired up the first time of the day, after the initial firing it starts easy. I changed the oil after running it on alky (approx 25 gallons I used) and the oil wasn't any different than before. All I did was run about 5 gallons of 87 through my fuel system (2 cycles) to get all the alky out. If you have a carb its worth a try, I liked the way my car reacted to it and the only drawbacks I noticed were starting issue and it running too cold, around 150 degrees.
