Default Re: LS1 Horsepower Factors

The horsepower differences between sticks and auto's are reflected in the index's. But it was originally to make up for the way auto's and sticks were back in the day. Now with the evolution of auto transmissions I think the sticks are the ones that need the half a tenth. But then I run a stick. You know there is something up with the horsepower when a engine combo that is 75 ci smaller rated at less horsepower in the same class can be 3 tenths and 4 mph faster. Just saying.
