You have to remember Duffman355 - "Furthermore, there are several factors that can affect the SAE corrected horsepower values as measured by K&N or at any other dyno facility. Some of these factors are:"
• Consistency of test parameters
• Tire pressure
• Fuel octane rating
• Vehicle condition
• The atmospheric conditions (dyno correction factors can vary from engine electronic correction factors)
I have heard from other members that the number is 140ish but it sounds like the above factors are playing a big part in the numbers.
