I made the intake out of 4" round alum. 3.5 top, 10% of bottom
3.5" and stock crank pulley should put you at about 9 psi at 6000 rpm. You just need to make sure you are not maxxing out the fuel pump or going lean for some other reason. If its a stock block, I would not rev more than 6200 rpm. Keep 91 or 93 octane in it and you'll be fine.
And yes, your video sounds fine to me. 2.6 liters is a fairly big blower for a 4.6 liter motor. Plus the blower is always pumping air and with the motor unloaded most of that air is going thru the bypass valve which is not that big of an area. My point is that there is a lot of air moving around and that makes some noise.The kb is well engineered and seldom has any issues.
Guessing it was boost loss from the intercooler.
If the intercooler cools the air, the air will condense and be at a lower pressure if it occupies the same space.Elaborate on that please. How can a normally functioning intercooler cause am”boost loss”?
My comment above was not directed at you in particularI'm not trying to split hairs. OP seems to think that there is or was a problem. I'm simply saying that the numbers stated are completely inline with what I've personally seen. I've had the same 2.6L KB for 10 years now including 3 different pulleys and 2 different crank pulleys (stock and +10% IW).
Well very bad news. Went on a second datalog. Maybe saw 5000 maybe 5500 rpm and the blower seized...gonna call kb tomorrow
Maybe what .10? I'm not even joking... I took the head unit off and there was shreds all on top of the heat exchanger. Thank god it didnt go into the engine. The screws are all screwed up too..lol no pun intendedWell that just sucks! I’m sorry to hear that. How many miles on the blower?

Here ya goDamnit! I hate that crap. I really feel your pain, I’d be pretty upset myself. I truly hope they will just replace this thing without a bunch of hassles.
When you get a chance, upload some pics.
I think material defect because I've done 3 pulls for my datalog and they were all fine..That’s pretty severe for no miles. Is there any possibility something got pulled into the intake tube and caused this, or do you think it was a material defect?
