Back to the shop...again

Alcohol always scared me after watching some of the old Indy car fires with no visible flames.

It's cheaper and much safer in conditions of pitstops. It has less energy per unit, so you run it much richer.

I haven't followed drag racing for many years but I do remember that 'alcohol' meant methanol. It may be that ethanol is used in dragsters these days but I'm sure it's not the garden variety you get at the pump. The fuel requirements of a dragster that is designed to run on ethanol for a few seconds, perhaps mainly in good weather, are a lot different from every day requirements of normal older vehicles used in all kinds of weather.

When a vehicle is purpose built to run a specific fuel, you can bet your bottom dollar they use fittings and components that will handle that fuel.

Pump gas with ethanol will not be a problem if it doesn't sit in storage. In my van it is in the tank and out the exhaust too fast for any problems. I use additive in the gas-cans with no problems after more than 12 months. Fiberglass tanks on marine vehicles have had reported problems. There are a lot of stories passed on as truth by repetition.

The main design differences are a higher flowing fuel pump and a bigger carb/EFI. Plenty of other types of racing uses ethanol (not methanol) too. Dirt track for example.

wtf are you talking about? the guy claimed ethanol makes race cars slower and using it is sanctioning body politics.
