BTW I'm assuming you have an internal wastegate and are running the stock(or something close to stock) turbo.

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 https://www.nopistons.com/forums/pub...#>/biggrin.png (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 knob 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.

Cool, again let me know how it works out.

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 https://www.nopistons.com/forums/pub...DIR#>/wink.png

https://www.nopistons.com/forums/pub...IR#>/boink.gif that is because you cant drive

Vosko would you say the 17 lbs Flywheel is better than the stock one and worth the investment. A friend of mine wants to know the order of mods he should do his TII in. We're at this point now.

if he has the money its a nice mod to do but its not necessary...........
