In a light car with a lot of power?

FST SS

I believe mine weighs 22 lbs. A stock one weighs 30 lbs. I have an SLP clutch and flywheel (2002 Z06 and steel billit) that's what they told me at SLP. I have not tried launching yet on my M/T's but can't wait. I know that with the stocker it would just blow the tires out in 1st and 2nd. With the lighter one it doesn't do that and it revs up like crazy.

Well im pushing 360 torque to the wheels on 285/30/r20's and with the steel flywheel i have to baby it outta first to keep from the white smoke cloud, and im running a 9in rear with 35 spline axels and a detroit locker with a 3.89 gear , so im going to an aluminum flywheel as soon as i get it installed and get a few test runs ill let ya know how mine felt vs the stocker. by the way my race weight is roughly 4200 due to the big subwoofers and 20 inch wheels and such. i tend to street race just a smidge so i think launching on the road with street low pros will benifit from an aluminum flywheel

I know this post has been going on awhile, but I went from a stock flywheel to a 18lb. billet, and I bog terrible off the line at the track now. I launch at 4500rpm's. and the car deadhooks and bogs to 1800. Worst mistake I made for the dragstrip. My 60ft. went from consistant 1.7's to 1.8's now. This is with a 3800 raceweight and hoosier 26" slicks.

What kinda power are you making? How about your 1/4 mi et and mph are they worse also. Why not just up your launch rpm? Are you using a 2-step? I was seriously considering the 18lb billet but now Im not sure. Thanks

I just got the nitrous going so 99% of my runs were na. Im running all stock IRS suspension with dragbags only. So Im kinda afraid to launch higher then the 4500rpm's. No 2 step. my na power is 423/403. In my opinion if you track quite abit, then I would pass on the 18lb. That's what I run, and regret it. Unless your pretty lightened up. In my opinion in a heavier car, it's not worth it. Plus after 20,000 miles my clutch still chatters, I think it's because of the lightweight flywheel.

Yeah, my car is pretty heavy 3900# + 98 SS. Making 430/410 but with a 2-step. I think the 2-step will keep the rpm's from dropping that much. What stage monster do you have? Did your 1/4 times and ets drop off as well or just your 60's?

So since this is long thread and I didn't get to every page, what would the consensus be if you had a aftermarket rear end (say a 9" or 12 bolt), would a lighter flywheel make up for the fact you picked up more weight/rotation with the rear?

with an aluminum flywheel at the track, you better leave at 6500 +
On the street its great though. I have a stock steel flywheel back in my car and it drives much better. easier to get the car to idle good too.

I agree. A sticky track can cause a car equipped with an aluminum flywheel to either bog or be inconsistent. I've been there, and went back to a steel flywheel. Bob

What do you think about the lightweight steel one. 18lbs. I'm not really planning on going with slicks or 6000 rpm launches. More like 4000 rpm off the 2 step maybe cutting 1.7 60 fts in a 3900# camaro with 4:11 gears on a 26 inch DR with 430 rwhp. I'm not looking to cut 1.4 60's or yank the wheels 2 feet up. I was hoping the lighter flywheel might not blow the tires off it. I agree that the aluminum is not a good idea for my car. Thanks

I was thinking the same thing, not going full aluminum and just using the 18 pound one.

Also if you're leaving at 4k on a 2 step you better be getting better then a 1.7 sixty.

I'm just tryin to say that I don't want to leave at 6k and I would like to run dr's. It could go faster in the 60. I was more questioning if I would need the heavier flywheel to launch like that on those tires or if the heavier flywheel will just smoke the dr's and a lighter one would be a better choice.

This.... He's right. I run the 18lb. billet steel, and I bog horrible everytime. No matter how high I launch. It drops down to 1800rpm's when it bogs. It sucks big time. Next time I pull the tranny, Im going back to a heavier flywheel.

Yeah Gto, I understand how it works in your situation and I appreciate the advice. But I have to think that launching off of a 2-step will stop the rpm's from dropping so much. Also since I am not looking to run a slick or cheater slick, I was thinking that the lighter flywheel might not hit the tire so hard. But if I don't hear anything positive about it, I will probably end up going with the 28lb flywheel. Thanks

HOW? that will not keep rpms up once you release it and drop the clutch. The 2 step only holds that rpm untill the clutch is dropped.

Not that the 2-step keeps the rpms up. But I would be launching at wot where he is launching at part throttle, so it will tend to bog more.

From my experience.... If you have a light car less than 3300 lbs, get a lightweight flywheel. My car 60's extremely consistant, and hard. (1.42,1.43, 1.44) Rarely ever higher than 1.45. I have the 15 lb chromemoly flywheel. Barry at qtp has an aluminum and had similar results prior to his last change. It 60'd very consistant.

Now, a GTO cannot expect to 60' like an fbody, especially with a lightweight flywheel, it's just too heavy.

That is kinda my dilemma. My car is 3900# with me in it, but I'm not trying to get 1.40 60ft times either and want to run a dr. So that is why i'm on the fence with the lighter one (I was thinking that it might not kill the dr's out of the hole and make up for the lesser 60ft up top). I know that a heavy car needs a heavy flywheel to 60' its best. But if I use a heavy flywheel with dr's, I think it will either spin or bog. Spinning is no good and if it bogs then I have the heavier flywheel to get spinning again. I was hoping the lighter flywheel would allow me to rev alittle higher at the line without spinning and rev quicker the rest of the way. Is my logic wrong? Do you think it is going to spin or bog either way because of using dr's? Thanks
