Comp stage 3 with Comptech FW here. If I had it to do over again I'd have just kept my stock FW.

 

you are probably right, I was trying to remember off the top of my head but their ultralight is like 8.6lbs, undrivable w/ boost IMO

 

Proautosport=7lb

 

What!?!? My turbo RX-7 (420hp) had an 8lb flywheel and I can tell you it was one of the best mods ever!!

 

I'm running a Comptech flywheel. For turbo I'd still opt for a light flywheel to help the motor rev up.

 

I had the same car (FD), same result. I flywheel really made the car more fun to drive. Yes, it was tougher to launch but once rolling shifting gears was a hoot.

 

I had a Fidanza flywheel. I noticed ZERO positive benefits. However the flywheel definitely seemed to add noise and make it very difficult to drive. I sold the flywheel and went back to my stock AP2 flywheel.

How does adding a heavier flywheel create more torque?

 

having a heavier flywheel helps you down low better because the heavier flywheel is able to resist change so you can hold your torque for example at launch

 

I have a fidanza as well on my S. Not boosted yet (it's sitting in my living room). Have a fidanza on my boosted 'teg too. Honestly, I have no problems at all on either car. I let some friends drive both and the only comment I get is that the motors rev up fast. They wouldn't of guessed I had a lightened flywheel had I not told them. No problems launching, bogging (even on steep hills), or chatter.

There was a post a few years back where someone actually dyno'd with and without lightened flywheel on a b-series and found he gained 2-3 whp.
