Thread: obx pulleys

anyone currently using these pulleys?? are they any good???

i have the set a its pretty good, i just got the crank one, my friend has them all and he went to the dyno en got 151whp and 136 tq with s4s , flywheel , msd, header, , cai and pulleys

only problem is that they don't have timing marks, I almost got a set but got a deal on the g spec pulley. I was planning to transfer the marks from the stock pulley to the obx.

thats what i did, i also got the cam gear from obx

so pretty good for the price, not no crappy ass pulleys

id just set the timing as you want it with the stock pulley, then fit the new lighter one and the ignition timing will be **** on

i had these pullies many moons ago and had planned to swap the timing marks over....this is what you do.

install the stock pulley and turn the crank to stock 15* timing.......now install the OBX crank and use a hack saw blade to mark it.......you now have a 15* timing mark.


put the OEM back on and now set it to 17 or 19* (what ever higher timing setting you prefer) and reinstall the OBX crank. use hacksaw blade and make another mark.

If anybody has or knows where I can get just the alternator pully please pmme the info
