Hey guys, probably gonna order a Clutchmasters Stage 1 clutch and their light flywheel on Monday. I found a deal for both for $570 and I found a shop near me to install it all for $280. I figure $850 for a new clutch and flywheel is pretty good. I've done a search and have a few questions...

1.) I've heard this mod can be bad for drag racing. Is this because the clutch has a harder time grabbing a lighter flywheel? But since the upgrade is a better clutch, it should grab the flywheel easier, right? I mean, I can see if you dumped the clutch it'd be harder to hook up, but slipping the clutch and keeping the rpms constant shouldn't be harder to launch than stock, right? Overall, this will help my 1/4 mile times considerably, right? Anyone wanna guess by how much?

2.) This is a good mod for an LS, right? I mean I can see wanting to get into VTEC sooner, but would a lighter flywheel negate the LS's good torque curve?

3.) How is this for daily driving? I expect it to be harder in traffic and stuff, but it's not that bad right? Is gas mileage affected? What about like freeway cruising speeds, higher or lower in the rpm's? Will it adversely affect my idle?

4.) I read that every pound taken off the flywheel is like 25 pounds off the car. Is this true? So going from 18 lbs to 7.5 lbs is gonna be like taking 250 lbs off my car?

Anything else I should know about this mod? Overall, would you recommend it. My main goal is to improve my ET's right now.

 

light flywheel is bad for drag racing due to the loss in torque i think. Its like you dont have all the extra weight on the flywheel to burn out and go, sure you can still do it, just a heavy flywheel (stock) helps for that kinda thing.
I have a toda flywheel however. and im more then happy with it...ok i need sleep, nite

 

I still don't see how a lighter flywheel would be bad for dragging. I mean, even if the launch is more difficult, the faster revs should more than make up for it. I can't see how it'd be THAT hard to launch with a lighter flywheel if you just keep the revs in check and slip the clutch till your tires hook up. With an aftermarket clutch, it will grab the flywheel pretty quickly.

 

awesome

 

How light is the flywheel you are installing. About 2 weeks ago I installed a 8.5 lb flywheel and clutchnet stage 1. I will try to answer you questions.

1. Unlike stated by someone else earlier, the problem with dragging is loss of potential energy from revving a heavy flywheel. This allows a much harder start. I personally don't think it is an issue unless you drag on slicks. From a street start, 1st and 2nd feel much better. Today I tried my first hard start, a 1-2 shift that would have chirped the tires before did nothing.

2. Lighter flywheel will decrease rotating mass. It will allow your engine to change speed faster.

3. I am still learning to use mine. I have 2500 miles on it in two weeks(2000 miles from a road trip). I just started playing with it a little today since it should be broken in enough. Taking off is tricky. I went to get an alignment done and they could hardly move my car RPM's are the same, freeway cruising is the same, idle was not affected in my case. If you go super light like 6.5 pounds, I don't know.

4. I have seen the math for this. I was confused.

 

Thanx for the response. I'd get a 7.5 lb flywheel. I don't really get your response to #1. Launching is only harder with slicks? You need to launch higher in the rpm with a lighter flywheel?
