Tired blower... this pisses me off.

Checked the clearances: .012 toward the rear of the case, .014 toward the front.

Well, I'm not sacrificing my summer to wait on my blower to be rebuilt, but at least I now know why this thing isn't building the boost that was expected.

No surprise after those boost numbers on your setup. That sucks tom .

I think i asked this question earlier, not sure if i got the answer or not. So what is the recommended clearance on the rotor to case?
I would like to check my 250 tonight.

Normal is about .004-.006 on a used 250 with some time on it.

Thanks MT i will check mine tonight!

Yup. I remembered right.

I guess the "brand new blower with only dyno time" goes hand in hand with the NIB inverter. What a bunch of BS!! $3k f'ing dollars for what will probably end up being a heat pump once it's in the boat. Yes, I'm a little mad.

250 clearance
 

Well checked mine and it is at .008-.009 on each Teflon strip near top of the case

Just keep in mind that boost PSI is a reference of airflow restriction. With your blower not getting hot at all,(blower not working very hard) then it could possibly be that your camshaft and head flow is working really well and thus your boost psi. reading is low.
Just a thought.

Appreciate it, but see the post above about the clearances being way out of spec. My understanding is that anything over .008 needs servicing. There's no way this blower will build strong boost until its serviced.
