aluminum flywheel for 1/4 mile car
#122
TECH Regular
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.
#128
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?

You want the extra rotational mass it will helpyou launch and also help with each shift. The aluminum is only good for road racing where you are constantly reving up and down quickly over and over and over.
If you or a buddy has some weights for lifting, (the round flat disc kind) take a small one and twist it back and forth in your hand, then do the same with a heavier one. The big heavy one wants to keep spinning and is much harder to slow down, so will your motor every time you launch, or shift, that big heavy flywheel will help force the car to accelerate a lil harder as it doesnt wnt to slow down easily. Hope that makes some sense!

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
#134
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.
#136
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

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
