Topic: 2.5 inertia ring

[Jlayne]

Does anyone know where I get a inertia ring for my 2.5? I'm looking for something like this:

I can't seem to locate one.

Tri county gear in Pomona California they have them in stock

Pardon my ig'nance but why not just use a hand throttle to bump up the rpms a bit if stalling out on obstacles is an issue for you?

This ring seems like a lot of work to install and you have to cut up your bellhousing to fit the starter too, which means more dirt and crap will be getting in there.

From what i've heard it is worth it the extra rotating mass realy makes the little 4 banger feel like its has more torque starting off.  You have to modify the dust shield on the front more so than the actual bellhousing.  Its not much harder to install than a clutch (mine will need a clutch soon) and I can have the trans sitting on the floor in 45min.




I was mainly curious to see if anybody on the east coast made them.  Cali is just a long way to ship ($$$) from me and if you have a problem its easier to deal with a close vendor.

By the way does anyone know what they run as far as $$?  I have heard 125 but not sure if that is correct.

I have one on mine; bought it about 3 years ago, and installed it about a year ago.  The difference it makes off the line is not drastic, but it is felt (especially if you rev the engine).  The stall RPM is lowered significantly, but in my case, I did it more to get a bit more umph off the line.

PS: I also have a RE hand throttle waiting to be installed...

as far as i know it's the other way around, you lighten the flywheel to help the engine rev up faster (and anything else that rotates for that matter), lower inertia, less loss fighting that - but it does help keeping it running at low rpm (same reason, more rotating mass).

[aw12345]

The idea is to make the flywheel heavier so it does not bog or stall the engine as quick, sat when you try to climb a steep hill or something like that, it kind of makes it act like a diesel engine, since the flywheel will release the stored energy when the engine starts bogging down. It will make the engine rev up slower though since it takes more energy to start rotating the heavier mass, but wants it rotates at speed it takes more of a load to slow it down which is it's intended purpose.

You are right; it takes more power to rev up, but if you rev up and then release the clutch, the engine has more power, which improves the take-off speed at intersections (this is important in Panama, as driving is abit nuts there!).

oh, i see - you chirping the 33s

Is a good way to drop a driveshaft

OK, let me clarify a bit more...  I rev the engine only to about 3K, and that launches the Jeep a bit better, but does not make the tires chirp (unless I'm turning when doing it).

[Jlayne]

What i'm hoping to gain out of it it to smooth out the buck bucks (for lack of a better term) on slow trail sections, crossing a rouch field, or crossing ditches.  The additonal rotating mass should help smooth those out.  As for the driveshaft/axle/trans mission, I could wind it up and drop the clutch and send one of those to the great junkyard in the sky right now.  I just take my SPED helmet off before I drive.
