It seems funny that no one can agree on how much power a modified Miata puts

out.  I have heard that a Sebring will increase the power up to about 170hp

on a 1.6L and that the 0-60 time decreases from the mid 9's to the mid 6's.

But now someone is saying that only around 139 hp is available with this

addition?  What gives?



I have in front of me a claim that the addition of a Jackson CAI, a header

and an exhaust sytem can produce "up to 145 hp"  That's a lot of power

gained from just three aftermarket intake and exhaust components.



Speaking of intake mods, one catalog I have says that the K&N and HKS

systems add 6 hp, but that their own mod, which looks almost identical to

the other two adds 7hp.    wow....  I'd better buy that one!  >>grin



I've also visited a web site that contains Dynojet Dyno graphs of a stock

Miata that was run on the dyno stock, and then run again after the addition

of the Jackson CAI.  The hp increase was about 4-6 I recall which is

different from the 11-15 hp increase claimed by yet another catalog that

sells them.



I realize that diffferent dynos produce different numbers, and I really

don't care how much power my car really has.  I'd prefer to think of it in

terms of what kind of other cars could it potentially embarass?



I think a list is in order, starting with stock and working progressively

toward heavily modified, that has the Miata, with specific engine

modifications in one column, and the cars it could knock off  in the other

column.  That would be much more useful. 



Ok, just a though...
