weighted flywheels

[1986cj7]

I read in a magazine some where about putting a extra 9 pound weight on the flywheel of a 2.5 for extra torque, I haven't researched it yet but this sounds like a good idea for a AMC 258 i6 / 4.2l or 4.0 not sure if this is available for the AMC 258 i6 / 4.2l or 4.0 but it sounds good. Didn't know if anyone out there has heard of this or done it? Or any opinions out there about this?

The wieght flywheel will help keep the crank rotating when you are wheeling but that weight also will hinder the ability for the motor to spin up which will hurt acceleration on the street and with the extra rotational mass will reduce gas mileage. The AMC 258 i6 / 4.2l has plenty of torques so in my eyes this would be counterproductive.

Thanks I just found some info on google about the weight of the flywheel will reduce acceleration, and actually only help at low speeds, I guess if you were into heavy rock crawling this would be helpful but for all around wheeling it is a bad trade off. Specially since I drive my jeep to the trail and back. Thanks for your info, and opinion

No problem.
