I have been wondering after this past weekend of racing in KY about how far off the HP/ET Calulators are on the internet. I have used several and they all seem to be way off from my perceived actual. Heres the situation.
Best Run in KY this weekend was a 12.214 @ 113 mph
Best Dyno to date was at the 2011 shootout of 350 rwhp.
When I punch in my car race weight (just over 3/4 tank) I get vary different HP numbers. Now I realize they don't mean much I was just wondering about why the large difference.
Wallaceracing has these numbers.
Your Horsepower computed from your vehicle weight of 4000 pounds and MPH of 113 is 474.36.
Then based on my ET I get this: Your HP is 433.88 computed from your vehicle weight of 4000 pounds and ET of 12.214 seconds.
Both of these are great, but I am wondering how far off these things are typically, especially when I only dyno'd 350 RWHP at the shootout this year.
Also when I punch in my actual dyno number HP and weight I should only be able to run a 13.025 @ about 103 MPH
I understand there will always be a difference, but this large of a difference?
Just wondering really. Are our cars that strange and throw off normal N/A HP numbers? I wouldn't think so.
But I don't really know hence why I am asking.
