Wow, I never knew the gains would be that high.

I've seen a Toda flywheel make a 12 hp difference on two identical setup SC'd S2k's on the dyno...but every motors different depending on the compression so theres an error ffactor there...14 sounds a bit high so your probably right, but who knows?

Sounds like a best case math senario to me. look at what it weighs and how much of that weight is toward the outer edge. I think that's what you have to take into account.

Maybe there's an engineer out there who can explain it.

I don't believe you get extra hp from a flywheel. All it does is free up more of the hp you already had for the wheels. I believe you may loose some top end with a flywheel though.

I've found that on a dynojet (which measures how fast you accelerate a known weight,) will show an increase in horsepower with a lighter flywheel.

Anyway you look at it, whether your adding or freeing up existing ponies, it still translates to more power to the pavement.

What's the tradeoff though? Heavier engine braking?

true that, it's an amazingly good mod, but wouldn't the rev drops between shifts go to quickly and it may drop to low, making the car little slower during shifts. I'm all for the install and am soon to get a flywheel myself, but everything good also has something bad.

I have the Comptech flywheel...I notice the difference...and no the revs don't drop to quick...as long as you don't shift like a parapalegic. I consider it easier to shift and normally just blip the throtle between shifts and it matches up prefectly and very quickly, even better then stock.

I personally noticed NO negative effects from the flywheel...revs don't drop to quickly, low end power is still good, top end is slightly better, I have nothing negative to report.
