I just ordered my meth set up and was on the phone with a bunch of meth companies and then I also called Whipple. You will want to inject just pre blower. I was originally concerned about meth/water getting on any exposed bearings or anything else that i could harm. This is not the case though. Read through the 5.0 forums and you will see almost everyone with PD blowers is injecting just pre blower. The meth/ water mixture is atomized instantly and therefor does not get on bearings but rather is sucked through with the air.
