I totally understand the benefits and disadvantages of an alum. flywheel. This ain't that kind of discussion! BUT...... is there an advantage for those HIGH RPM(8000+) small block to use a 40/50+lb. flywheel to keep the RPM up between shifts OR....would a light wheel get the engine to "wing-up" on the launch? Unlike a street ride...you racers have "the gear" to keep the engine operating in it power zone most of the time so we can take that out-of-the-equation. So the question is the "launch" I guess.(and weight of the car) What do you fellas run?...Heavy f'wheel or light f'wheel? 6sally6 See y'all in Aiken(House-of-Hook)
Don't know the answer to that question. But check out the Gene Shwartz vids on YouTube, high winding small block with a heavy flywheel.
From what I remember, the heavy flywheel was used for a real heavy car to assist in launch and inertia between shifts. The light flywheel sounds cool but isn't as useful as it is cool sounding. I have a light flywheel in my 32 because I like real responsive engines.
The heavy fly wheel is a positive on heavy lower torque cars, if you launch your car and it bogs of the line you could benefit from a heaver flywheel. If it spins the tires to much, a lighter wheel might be needed.
