Allow myself to quote myself (lol)...from the same thread:

"....I looked at the owners manual for some numbers, listed below (for a base w/ manual transmission):

217 HP ;Weight: between 2777 lbs and 2954 lbs, which I averaged at 2866 lbs; 0-60mph 6.5 sec

Now I understand that these numbers are not scalable, but for giggles, if they were:
2866lbs/6.5sec=441 lbs/sec or 0.002267 sec/lbs.
Given 5 lbs reduction, that would equal just 0.01133 sec reduction on the 0-60 time, or with a car stripped of 100 lbs, an increase of 2/10ths of a second 0-60...which somehow sounds about right (at least to me)....

I should stay away from numbers, and stop asking questions."

And I'll stand by that comment, or at least that I should stay away from numbers

Lets test it.

Anyone in LA or OC have a stock 986 that they would be willing to use for a couple of 0-60 runs?

I'll bring my Spec Boxster (stock engine and trans) which has been weighed repeatedly at races (2655 lbs with 195 lb driver and 1/8 tank gas).

We can swap cars so we have two sets of data to average out the driver. You'll get to drive a Spec Boxster.

I also have an AIM Solo GPS timer which has a 0-60 mode. It starts counting as soon as motion is detected and stops the time at 60mph.

Then we can do the maths and know roughly what 1lb is worth in terms of 0-60 mph.

Its not perfect, but it will be fun and we'll have a rough order value to banter about.

PM me if interested.
