sorry about the crappy formatting on that last post – and I blew the SAE address:
http://www.sae.org/

Even non-engineer Miataphiles can (seriously) find some interesting stuff on their site.

Well, thanks for correcting me! I suppose your source is more valid.

I’ve had my 1.6 up to 125, but although the speedo seemed accurate
around 60-70 as measured over a few miles, I doubt it was a real 125mph.
That would make the 116/120 ratio a bit questionable.

my book here, but this abstract of an SAE (Society of Automotive Engineers) Standard
should show the correct usage:

SAE Standards

                        Document Number: J-690
                        Date Published: 1992
                        Title: Certificates of Maximum Net Horsepower for Motor
                        Trucks and Truck Tractors

                        Scope:
                        In the report of the SAE Motor Truck Rating Committee on
                        Ability Rating published in the January 1940 issue of the SAE
                        Journal, it was recommended that pounds per certified net
                        brake horsepower delivered to the clutch or its equivalent be
                        used as the index of the potential ability of a motor truck or
                        combination. This report defined the term ‘certified net brake
                        horsepower’ in detail and recommended that certain data be
                        provided to support the certification. The accompanying forms
                        provide a method for the presentation of the data specified.

For $15 you can order the standard and read the detailed definition of "certified net
brake horsepower" from htttp://sae.org

The difference between brake, net, gross, flywheel, drive-wheel horsepower, etc can turn
into a lengthy (but interesting to some people) discussion! Hope this helped

Oh, it’s possible.  :)

At least going by the stock speedometer, I gather that it might be off
~7mph or so.

That’s rather odd because 127hp is official mfr. data from GM. Does GM
actually measure horsepower at the wheels? I doubt it..

There is a K&N filter out for it. I also saw an ad for RAV4 sway bars in
SCC. Why, I don’t know..

As to why the K&N and sways exist for the RAV4… simple: there are
indeed RAV4 enthusiasts just like there are Miata enthusiasts. And they,
just like us, like to improve on their vehicles. Hmm… I guess sway
bars are a bit odd though. <g>

Doh. See, the problem with questions of the "just wondering" variety is
that I am usually left feeling stupid afterwards. Beats ignorance,
though..

Come to think of it, why "base"? An hp is an hp is an hp. Is a "bhp"
somehow different?

Hmm… the SC2 R&T tested on 12/96 (and in 1997 Road Test annual) shows
124 hp. Perhaps another magazine using a different dyno got the 127 hp
reading. It is not uncommon for two dynos to give two very different
readings.

Btw, the RAV4 does the 0-60 in 13 flat.

It’s a fairly meaningless relationship. My ’60 MGA allegedly had 79.5 bhp
(old method of measuring, would be more like 65 bhp today), and it topped
out at 105 mph.
