No you just need the spacer for the oil filter adapter or you can dent the oil filter. I had an od balancer and all I used was the spacer and had no issues with leaks.if you get a 10% overdrive, the oil filter will need to be relocated, 5% doesn't take any extra work and is cheaper.
And some gtx badges lolGet an SLP 3.5" press on pulley..... it was offered through the OEM/ dealer as an upgraded trim package
if you read any of anything, this is in park, revving it. tq is not a issue here dummy. a bad blower is. cause your not making any boost revving it in park are ya?That doesn't mean the blower is the problem. The motor makes significantly less torque without the blower belt on.
