Not sure, but when i take off from a light i am using the bottom end of my power band ?

Hayduke did it affect your acceleration onto the highway or driving at highway speeds?

I run one w/ a CF-DF clutch and like it, a lot less tendancy to stall on the trail. It is a bit slower accelerating but with 4500 lbs. of 4Runner and 116HP, its no big difference. Also the heavier flywheel can soak up more heat to help cool the clutch. No subsitute for gears but I did find the heavier flywheel let me run about 1 gear higher on the trail and keep the engine RPMs lower.

As far as being concerned about money, I built the snot out of my truck, cost be darned. But that was to gain something. For a clutch I went with a genuine Toy reman, for no loss of service life or function and a significant savings. I have used these clutches for years in prior vehicles with very good success and long life. A dual ultimate crawler makes the life of the clutch even easier, put your money toward that.

If I had a 4.3 or 3.4 I might have made other choices. YMMV.

And thanks for the replys from the 2 people who actually have heavier flywheels and actually answered mxitup's original question <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" />

This is how I drive a clutch...
I release the clutch with little or no gas. Once it engages I give it gas and finish letting it out. My 3.0 and my 2.4 have always had enough torque at idle or slightly above to drive in this fashion. And since the engine is not spinning fast, there is less burning of the clutch. The heavier flywheel stores extra inertial energy that can be used to get all the runnning gear turning. So the way I drive, I use the bottom end of the torque curve.

People who rev their engines to 2-3000 then dump the clutch are running in the middle-top of the torque band. Guess who is going to replace a clutch first.

I've always driven manual trannys, always put over 100,000 miles on a vehicle before I got rid of it, and the 4Runner is the first vehicle I've replaced a clutch in. Because the rear oil seal lubed the old one. In fact my Corolla has 249,000 on it's original Toy clutch.

I didn't notice a lag in acceleration at highway speeds although the laws of physics dictate that there would be. Keep in mind, the TRD flywheel is only 5 lbs heavier. I've heard of other flywheels weighing from 8-10 lbs. If you do a search for some of the previous posts, it seems that folks with the heavy ones disliked them because of the lag in acceleration. I think the TRD is a good compromise. You forget it's different because it works so well.

I'm also running a CF/DF clutch w/ heavier flywheel and very happy w/ it. It allows me to maintain my speed on the highway w/o having to downshift as often on hills.

I think this weekend i will take my CF/DF and heavy flywheel out and repalce it with stock swap motors take my lift off put stock tires on and sell my runner LOL and start over with a automatic <img border="0" title="" alt="[Wink]" src="images/icons/wink.gif" /> <img border="0" alt="[Ignore]" title="" src="graemlins/ignore.gif" /> Ease up guys just tring to help

A 5lb heavier and 8-10lb heavier flywheel could perform exactly the same depending on where the extra weight is placed. If the 5lb extra mass is at the outer edge, and the 8-10lb is dispersed from center to the edge it is possible for the lighter to store more energy. I'm guessing Toyota located the extra mass correctly and it was all that was needed. I'm sure someone will correct me if I'm wrong. <img border="0" alt="[Nerd]" title="" src="graemlins/nerd.gif" />
