I put one on Sandy's car. I got it in a trade deal. I never weighed it. Hmmm.. should have.
Anyway, the car will be on the road soon. I have a 2.0 with stock injection. We shall see if I like it.
The thought is it will free up some hp. and spin up faster out of the corners but may suck on the freeway when your trying to hold a steady speed. Also there is an issue with the engine stalling when your in town and let off the gas and let the idle drop while your foot is on the brake. Without the inertia of the heavier flywheel will sometimes the engine drops below idle and stalls.
It affects idle, freeways speeds are not an issue...you are on the gas.
The idle may annoy you.
It can work if the car is in perfect tune.
I have run an 11 lb one for 10 years...
I know when I need a tuneup...it stalls at the lights.
