Boost will go up if you feed the inlet side of the blower more efficiently.
I've heard peaple say that the blower will pull the air through a restriction.....NOT......blowers don't suck.....they create a void or depression and then the air moves in at atmospheric pressure (14.7 lbs) and fills the void. The more bends and twists you take out of the system and the more volume you add, the better the blower will "Load the Rotors" on the intake side. And the more air you can load into the rotors the more it will pump. They are also sensitive to "direction" of flow on the inlet side.
I spent a lot of time on this with my Kenne Bell and got a ton of gains out of it but by time the boost hit the 23lb range I couldn't stop the belt slippage. One minute it would give you 23 and the next time out it would hit 18 and then when you look under the hood all you see is black belt dust on everything.

Dale are you saying improved airflow prior to where the boost is measured (intake) will increase boost, and this is good.................but worse airflow after the intake ...say bad flowing heads, this will also increase boost, but it is bad?

Any restriction at the inlet side of the blower will cost power and sometimes boost. I had a centrifugal car that lost OVER 300 rwhp with a mandrel-bent 180 degree turn at the inlet of the blower for a fresh air inlet. I removed the bend and picked up over 300 rwhp.
If the engine is not efficient (poor exhaust, head design, etc.) then you can increase boost and still not make more power, usually start to lose power as the air gets so heated from the extra boost but the charge is just stacking up in the engine. But if you pick up boost by changing something on the intake side of the engine it is always good, it means a restriction has been improved or eliminated.

Actually Steve I would have said Modifications made before blower inlet and Modifications made after blower outlet.
Well....you know what I mean

Looks great Jody...here is mine almost finished with the re-polishing of the blower, I still need to work on the snout and the other side. I should finish polishing today.
Hope to assemble it tomorrow.

Yep, yours is awesome! I normally try to keep the engine areas as stock appearing as possible due to living in California; mine will pass smog, but you don't really want them crawling all over things when they open the hood and see a bunch of mods. But now with the new law I don't have to smog my truck until 2009 so I've got 4 more years before I worry about trying to disguise the JLP intake.

Thanks for the compliments and the info on your install
