i must be dense. let me try this again.

i have a mustang 3450lbs(+0.2) on 275 DOT tires(+0.4).

where do you add the 0.6 points?

To whatever is your unadjusted power to weight....so if you make 400whp at 3450lbs, that would be 8.625. Then add .6 to it for a final number of 9.225. Meaning, you should aim to have you power to weight at 8.1 to meet the limit of 8.7.

I look at it backwards... I deduct it from the 8.7 meaning you can shoot to be at 8.1 lbs/horse. But if you drop weight that +.2 goes away.

thats where i got confused. i thought + points were added to the 8.7
and - points were subtracted. in fact its the opposite.

Well the other way of looking at it is taking your power to weight then adding the points and getting back to 8.7.

I.e. you're at 8.1 then add +.2 and +.4 and that = 8.7 which is the min hp to weight. It all works out the same in the end, but just different ways of thingking about it.

Or in your case you're at 8.625 then +6 puts you at 9.225 meaning you cand drop .525 to be at 8.7.

Like I said... I like to think about it in terms of the adjusted HP/weight I can be at. In my case if I'm running 275 tires that gives me +.4 so I can be at 8.3 instead of 8.7.

Clear as mud

i have only a handful of laps at vir. my best lap time was a 2:17 during the top gear
shoot in september. my only time drivng the current car there. admittedly i was not
running hard, but still...a 2:04 sounds well beyond what i will be doing there.

impressive
