The Racing Beat aluminum flywheel is 8.2 lbs, and the total weight increases to 12.5 lbs when you add the counterwieght and hardware. It also has a replaceable steel friction surface (that is included in the 8.2 lbs weight I quoted). If the weight for the SR flywheel is just for the flywheel itself, expect the total weight to be 13.5-14 lbs. I really like my light flywheel, but it might be better to go with the stock flywheel or the RB 17 lbs flywheel if you want to drag race the car. A light flywheel will increase your launch RPM substantially and make the car harder to launch. I haven't heard of people warping aluminum flywheels, but the added inertia of a heavier flywheel seems to be easier to launch and better for drag racing generally. I still don't know if the energy stored up in the flywheel at launch (more inertia = more stored energy) is a significant factor, but ease of launching alone makes the heavier flywheel better for drag racing, in my opinion.
The light flywheel makes the car rev faster and frees up a good bit of power in first gear (50HP?), and a little power in second (15HP?), but after that you aren't accelerating fast enough for the difference in inertia to give you any significant increase in power at the wheels (<5HP?). The light flywheel also makes it easier to match revs for downshifts (heel & toe), and it matters much less if you don't match them right.

Holy moley! Look at the big brain on maxcooper. Yeah, I believe you with the power numbers in the higher gears. But subjectively if feels a lot better. The butt-o-meter never lies 
(or is that the magic eight ball that never lies?)
7mech: you're on the money. I basically have a stock setup. I'll try your advice the next chance I can. :bigthumg:

Jerk Racer: Cool let me know if it works for you. Oh yeah you must remember that I live in Texas and generally the temps stay higher and that my distance above sea level my be different than yours. These factors may affect how your car boosts.
Maxcooper: Thanks for the info. I think I'm going to stay with my stock flywheel because I have yet to road race my car. I may sometime in the future, but untill that day comes I think my stock flywheel will suit me just fine.

Well, I had all the switches set as you suggested but the mild/sharp **** was set to the middle. I haven't been able to test it out yet. I will tomorrow. Over here near Seattle this time of year the weather is really good for turbos. I'm also at a very low elevation.

i drove silver 93's FD with 9lb flywheel. its nice but i wouldn't invest in a LW flywheel unless you have $$$ to burn or your flywheel has cracks. i have the stock flywheel in my FD and a 17lb in my old TII, it revs more than fast enough for me
