If I was to put it a Carbonetics twin disc clutch along with the lightened flywheel, would these show up at all on a dyno?

I think obviously not but still curious. These mods would show up on a time trial for sure but seriously would there be any gain on a dyno from them?

 

Theoretically, yes. Realistically, no.

 

Think of it like a 4.08 final drive... technically, you aren't making more power, you're just getting up the revs faster

 

Kinda of what i was thinking too. It'll get you there faster but your technically, as far as i know, not making more power, just getting there faster.

 

Technically, a lightweight flywheel will give you more power at the wheels.

Wheels/tires are a rotating mass that robs power, right? Flywheel is the same concept, just on a much smaller scale.

Realisticaly speaking, the gain from a flywheel is so small that it falls well within the margin of error on a dyno.

This is also why dynapacks read higher than dynojet/dyno dynamics/mustang; they connect to the hubs, which eliminates the wheels/tires variable.

 

I can't argue about the flywheels, but as for this - technically, dynos need to be "tuned" too...

The Dynapack at Blacktrax has been correctly calibrated, and it reads about the same as the Dynojet at DynoSpot, which really isn't that much higher than my friend's notoriously low reading Mustang. My car makes about 20 more horses on the Dynapack and Dynojet than the Mustang... I can get those same numbers on other Mustangs in the area...

 

IMO, any dyno that can "read what other dynos read" is suspicious...

Lightweight wheels and tires will register as additional power on a dynojet (compared to heavy wheels and tires); it will have absolutely no impact on a dynapack.

 

It's all on how you set up your dyno. Correctly set up, it should compensate for more than you are thinking it does. I think the only variable dynos can't compensate for is air density.

And IMO, up to about 10hp difference between different dynos would be pretty similar, depending on weather.
