dyno nunbers and conditions

Yes weather can greatly affect engine performance. Factors such as temp, humidity and even barometric pressure will affect the power. And as has been said, each dyno is different. Even the way the car is tied down can make a difference. Don't get too wrapped in the number but concentrate more on the feel. The only number that matters is elapsed time. That is what dictates the power and performance. Besides, a car will not match a dyno number anywhere but on that dyno at that time.
