LS1 Horsepower Factors
I recently bought a copy of Nitro Joe's Stats on Ebay.(Nice job by the way).
I really wasn't aware of some of the horsepower factors in some of the classes I don't compete in. It appears that there is an LS1 in some bodies that is at 381. Then there is a manual transmission combo that is something like 40 horsepower less than the 381 of the same body. Then,if it is in a Corvette,you see 350.But in a Firebird, it's 381 Are these engines all the same or are there differences? |

Re: LS1 Horsepower Factors
Same setup as the Corvette. Factored to 340 hp.

40 horsepower difference based on transmission type? It doesn't matter if they were at 340 or 380,I still wouldn't ever outrun one. |

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.
