I've searched and searched. I just need help please. I got the crank bolt out but the pulley just won't budge we have the pulley remover but it ain't budging any ideas?
Depending on the puller you have you may need the longer crank bolt slightly in still so the puller has something to push against in the center. Then use a wrench on the puller, it will come out.
Necessary- eh, probably not, but that depends on who's tune your running- extremely, extremely beneficial- absolutely.
The IAT located pre-blower is worthless for you now. You might as well leave it disconnected. It's input will be completely useless.
Post-blower and you'll be able to advance/retard timing based on the temperature of the compressed air- this is a HUGE advantage for both safety and power.
