dyno on new SE-R

[spdracer@mail.utexas.edu]

I remember the relatively low dyno number was discussed a long time ago.  Mike
thought it might be the flywheel as it's a dual mass one that weighs like 40
lbs or something ridiculously heavy.  Since the car was tested on a dynojet
which is an inertial dyno(i think that's the term); anywayz, it determines HP
by determining torque by how fast the car can accelerate the roller of a known
mass.  As you know, the more mass there is, the longer it takes to accelerate.
That's why you want light wheels, flywheels, etc.  BUT, when you add a light
flywheel, you aren't increasing HP, just reducing the mass you need to
accelerate.  BUT, on the dynojet, it'll look like a HP increase because you
reduced the mass in the rotating system, so you accelerated the roller faster,
so it looks like you have more torque and HP.  A brake dyno would probably give
a better indication of how much HP the Spec-V makes.  BUT, the dynojet kinda
gives a more realistic real world value.

In the SCC great 8, if you look at the dyno charts though, since the Spec-V
makes so much torque, it makes a ton more power down low than any of the other
cars except for the WRX and maybe the Tiburon.  Just compare the HP at like 3k
or 4k rpm.
