aftermarket lightweight pully?

[cb7-tcakes]

ok pretty much i need a different harmonic balancer, jy wants 65 for used so i was thinking just getting a lightweight aftermarket pulley but not sure if its a safe way to go on a stock f22 w auto tranny? Does a lightweight pulley work like a lightened flywheel?

my plan was to use the lightweight pulley on f22, until i swap my h22 in and then slap it on h22 since i got a 9lb fly with it the h22.

yeah less rotational mass and so you'll "regain" some power loss but i doubt it's much power to be had. i'd look else where or just save your money until you've had enough for your engine swap.

why do you think you need another harmonic balancer?

Reduction in rotation weight is worth more then removing stationary weight on the car which is a good thing.

Some people have reported oil pump failure due to a lightweight crank pulley. I've had one on my H22 for about 7 years now with no problems (and lots of driving).

DO NOT get a cheap pulley, though. Unorthodox Racing is the only brand I would ever trust. If you get a cheap "ebay" pulley, it may not be properly balanced, which would very likely lead to engine damage.

the key slightly dug into the side where key slides in, nothing major, and when putting the pulley back on its wobbly so i dont really trust putting it back on, crank is fine.

I have the h22 sitting in my garage im just waiting on esp mounts to come in to start the swap.

Oh lol. Yeah that would be a good reason to have another crank pulley installed especially if you need the motor to last just a little longer.

Good choice on going with the ESP mounts. I used them in my 5sp conversion.

i put a UR crank pully on my a6 when i rebuilt it and the pully rubbed like crazy and ate a hole in my brand new lower timing cover.. I took the pully off and the back of it looks like a brake rotor does after the pads wear to bare metal..it was pretty rugged. I also noticed it wobbled like crazy when i had it installed even after i torqued and re-torqued it.. just my 2 cent

guess ill just go with stock then, good to know for future upgrades though.

i've been looking for an crank pulley for an f22 but no luck i search UnorthodoxRacing.com but they don't make for f22ax, does the h22a1/a4 fits f22ax?

[theSOB]

i think they discontinued it. the one for the h should fit

anyone know for sure because i was thinking of buying the h one to use on my f but wasnt sure about fitment.

[deevergote]

The H one will fit. The belt width will be different, though.

what causes crank pullys to wobble???

crank bolt decided to come lose, pull over to the side and i see my hb rattling back and forth and that caused the inside of the hb to be a little messed up.

You'd be surprised how many stock motors have grooves worn into the timing belt cover with stock crank pulleys...
