Default Alcohol Anyone??

I have a SBC that makes around 775HP and has run 9.6 @ 140 on Alcohol...What do you think I will lose as far as HP and/or ET if I switch over to race gas?? Looking for anyone who has tried this with their combo and knows first hand what the results were.

Thanks, Joe

Thanks Hammer, My combo was running a sheet metal intake with a split alky dominator (2-2barels) and I want to switch back to a ported cast aluminum intake with a single Dominator for class reasons...I'm just afraid the car might lose alot of ET.

I would be ready to loose as much as 2 tenths.

I would be very happy if thats all I lose! I was thinking I would lose 4-5 tenths. Thanks again for your input.

The intake swap may hurt things, getting the carb/intake correct when you change will be key or you may loose a lot more then 2 tenths. If both setups are good there is no reason to loose anymore then this though.
