I only have limited experience, so FWIW my opinion.

Typically in hot weather you can see 0.3 tenths in the 1/4 mile, so maybe .2 in the 1/8th mile. The torque improvement can show more improvement in the 1st half of the track.

In cold weather, the ET difference will be less. And in mineshaft air it might be too close to call. But people have reported different results in different combos.

I also am a firm believer that alcohol can make a car more consistant from less change with weather changes. But some gas combos are very consistant too.

If you go alcohol injection, give serious thought to a gas primer/idle system. This helps put/keep heat in the motor, easier cool weather starting, saves fuel, etc. Recommended, but not required !




and A+ for the primer plus gas system. It sure makes my life better. I'm with Ryan J. What do you mean? Alky loves compression.
