Actually it's the other way around, in most cars you LOSE low-end torque and GAIN top-end horsepower.

This article will expain most of your inquiries.

The OEM F20 flywheel is about 14 lbs.
The Comptech FW is about 9.5 lbs.
There have been reports that with such a lightweight flywheel the engine "dips" less when you press the clutch at idle and the revs climb a bit quicker to normal idle too.
Not much difference in normal driving.

I'm looking forward using my Comptech FW + ACT PP with the 4.57's.
I will post my experiences.
The old clutch is still working, so it may take a while.

Most of the energy the engine is producing is used to accelerate the car, not the flywheel.
Heel & toe throttle blips to rev match may be easier?

 

Don't forget the the AP2 has a slightly heavier OEM flywheel at 18-19 lbs.

You will feel a loss on the low end when your coming off the line with a light flywheel. If this car is your daily driver and you do a lot of stop and go driving I wouldn't recommend anything lighter than the Comptech flywheel.

I drove a s2000 with the Toda flywheel which is around 7-8 lbs. and I stalled it several times going around the block.

 

The flywheel operates with the principles of inertia - heavier flywheels are slower to change speeds, thus, it effects how fast or slow the rpms rise and fall - when you simply press the gas pedal, when you engage the clutch, etc., a heavier flywheel will slow the rate of increasing and decreasing rpms. This can be a good thing when you want to keep rpms from dropping out of the power band too quickly.

If you have nothing but I/H/E and don't need to replace your clutch, don't worry about your flywheel. If you are getting ready to replace your clutch, you may want to think about a heavier or lighter than stock flywheel. How you drive your car would dictate this, but if you're just tooling around, you might as well get OEM imo.

 

I have had the Toda for a number of years and am very happy with it. Would buy another if I needed a FW.

 

I rock the fidanzza 8lb FW, love it

 

If your rev match or heel toe, it makes it much easier and quicker with the "blip."

 

That's the real reason for this mod. I love my Comptech
