I Need Help With A Math Problem

[Larry Hill]

A good friend of mine has a heads up in Stock second round. So for fun I looked at the HP rating of his competition. Much to my surprise the 1970 Camaro 350/360 in Super Stock was de-rated from 360hp to 325hp 12/19/02. I know the AHFS was in affect at that time and according to the rules: a competitor my have requested a reduction in Hp rating. The scale for reduction was based on the year’s previous runs by that combination. The reduction was written as 1.25% if the fastest run was quicker than -.165 under the National index and the class average was below -.550. If the quickest run was -.115 to -.164 under the reduction was 2.25%. So to receive a 35 Hp reduction using the 2.25 % I believe the start Hp would have to be 1555hp. Would y’all mind running the numbers to check my math. And for example a 15 Hp reduction on an engine rated at 420 the start Hp would have to be 666 Hp. I wonder how all this happened with the AHFS in affect?
