I have a '91 N/A, soon to have exhaust and cold air box, is the added expense of a lightened flywheel like the ACT unit worth the money?

Will it adversley affect drivability?

 

im curious as well

 

Might as well just stick to the regular steel flywheel.. Lightened flywheels mainly just help in acceleration. But since you've added the cold air and exhaust, the flywheel might make up for (a possible) loss in low end torque.

 

My daily driver vert has a Racing Beat Lightweight Steel Flywheel. I think its like 16 or so lbs compared to the stock which is around 22 lbs or so. It definitely helps acceleration, doesn't really hurt driveability. All you have to do is slip the clutch a little more, and give it some more gas to get started on a hill. Definitely worth it, IMO as long as you're taking out the motor/tranny anyway. I don't know if its worth pulling the engine or tranny to install though. But if you're replacing the clutch or motor, etc. I would definitely recommend a light flywheel.

 

I don't think a lightweight flywheel is gonna make the car really hard to drive. I spent some time driving Blue TII's S4 with a HUGE streetport and an aluminum flywheel and it wasn't too bad once we got the Haltech dialed in. Running it with stock ports should be really easy. You'll just need to be kinda smooth taking off, since the motor will respond quicker to getting in or out of the throttle. At worst you might stall it if you aren't paying attention.

 

I have a RB Aluminum Flywheel on my FC. It's plenty streetable with the least Indifference of making It a pain In the ***, In terms of every day drivability.

 

It's awesome.

 

Its fine. I have a 9lb flywheel and I live in SF and have to deal with hills all the time, its no worse than stock, once you get the hang of it.. which took all of 5 minutes.

 

However, I don't recommend you get one If you are drag racing. I learned that the hard way, just the other day In fact...

 

Launches suck. Big time!

 

I have a 9.5# flywheel. The only thing you have to get used to is giving it more gas to get going other than that it is just like the stock one.

 

Hmmm, well sounds like those that have tried it, like it.., not too sure about having to slip the clutch MORE though.

Yes, as far as the drive train, the only thing left in the car right now is the rear-end.

But from what I am reading about the ACT unit, it is set for the TII (240mm), and so that would mean that I also need to replace my N/A clutch assembly due to diameter and mounting depth.

So this is starting to add up, $450 CDN for the flywheel and $400 CDN for the clutch= $1000 taxes in!!!!

So is it still worth it?
