lightweight flywheel engine braking

[CB7lx91]

So you replace your stock 17lb flywheel with a lightweight 8.5 lb. The engine will rev up and down faster, but how is engine braking affected? I would assume it would brake quicker, but I don't know lol

Anyone know?

i have a fidanza aluminum flywheel in mine, it didnt really change except for the fact that with my stage 3 clutch it engages really hard and can be a little irritating. i gotta get the rpms up then engage the clutch, but it still engine breaks the same

id think it might make it stop faster, less momentum keeping it spinning. reason i stay away from those shiesty flywheels. 12lbs is the lightest I will go. screw having to rev to 5k rpms to take off froma light cause you running 1.5hp weed wacker flywheel weight. i mean damn briggs 5hp engines use 12lbs!! they heavy for a reason. i know this is a never ending arguement, but thats my opinion.

From a DEAD stop at a light, I rev to about 1300 and take off fine. No studder/shudder or anything and my flywheel is 8.9lbs.

yeah i wasnt being dead serious..lol i know how they are my friends gsr civic has a 9LB. i hate it.gotta give it more gas than normal to go. its also prolly a lil diff with the f22 vs d16,b18.....the torque factor.

I have an 11lbs flywheel and exedy clutch and I can slowly let the clutch out, never touch the gas and not stall the car. As for engine braking, it will feel the same.

ive engaged from third before but using the gas. compression also helps engine braking

Do aftermarket flywheels need to be balanced? How important is it and how is it done?

you can do it but i wouldnt bother. if i lightened an oem flywheel, i would def. balance it.

Just get a quality aftermarket wheel and it's fine.
Fidanza and ACT are some of the only brands I would trust to go below 11lbs.

how do you lighten a stock flywheel? you talking cutting holes in it? or milling it? machine shop here said it cant be done on a stocker.

you trim the material behind the face and you produce a taper so you dont lose strength.

round table on mill.
